7.Description:
(en)BACKGROUND OF THE INVENTION
The present invention relates to novel azabicycloheptyl compounds. The compounds possess valuable therapeutic properties and are suitable, in particular, for treating diseases that respond to modulation of the dopamine D 3 receptor.
Neurons obtain their information by way of G protein-coupled receptors, inter alia. A large number of substances exert their effect by way of these receptors. One of them is dopamine. Confirmed findings exist with regard to the presence of dopamine and its physiological function as a neurotransmitter. Disorders in the dopaminergic transmitter system result in diseases of the central nervous system which include, for example, schizophrenia, depression and Parkinson's disease. These diseases, and others, are treated with drugs which interact with the dopamine receptors.
Up until 1990, two subtypes of dopamine receptor had been clearly defined pharmacologically, namely the D 1 and D 2 receptors. More recently, a third subtype was found, namely the D 3 receptor which appears to mediate some effects of antipsychotics and antiparkinsonians (J. C. Schwartz et al., The Dopamine D 3 Receptor as a Target for Antipsychotics, in Novel Antipsychotic Drugs, H. Y. Meltzer, Ed. Raven Press, New York 1992, pages 135-144; M. Dooley et al., Drugs and Aging 1998, 12, 495-514, J. N. Joyce, Pharmacology and Therapeutics 2001, 90, pp. 231-59 “The Dopamine D 3 Receptor as a Therapeutic Target for Antipsychotic and Antiparkinsonian Drugs”).
Since then, the dopamine receptors have been divided into two families. On the one hand, there is the D 2 group, consisting of D 2 , D 3 and D 4 receptors, and, on the other hand, the D 1 group, consisting of D 1 and D 5 receptors. Whereas D 1 and D 2 receptors are widely distributed, D 3 receptors appear to be expressed regioselectively. Thus, these receptors are preferentially to be found in the limbic system and the projection regions of the mesolimbic dopamine system, especially in the nucleus accumbens, but also in other regions, such as the amygdala. Because of this comparatively regioselective expression, D 3 receptors are regarded as being a target having few side-effects and it is assumed that while a selective D 3 ligand would have the properties of known antipsychotics, it would not have their dopamine D 2 receptor-mediated neurological side-effects (P. Sokoloff et al., Localization and Function of the D 3 Dopamine Receptor, Arzneim. Forsch./Drug Res. 42(1), 224 (1992); P. Sokoloff et al. Molecular Cloning and Characterization of a Novel Dopamine Receptor (D 3 ) as a Target for Neuroleptics, Nature, 347, 146 (1990)).
Compounds having an affinity for the dopamine D 3 receptor have been described in the prior art on various occasions, e.g. in WO 95/04713, WO 96/23760, WO 97/45503, WO98/27081 and WO 99/58499. Some of these compounds possess moderate affinities and or selectivities for the dopamine D 3 receptor. They have therefore been proposed as being suitable for treating diseases of the central nervous system. Some of the compounds described in these publications possess a pyrrolidinylphenyl structure. Unfortunately their affinity and selectivity towards the D 3 receptor or their pharmacological profile are not satisfactory. Consequently there is an ongoing need to provide new compounds, which either have an high affinity and an improved selectivity. The compounds should also have good pharmacological profile, e.g. a high brain plasma ratio, a high bioavailability, good metabolic stability, or a decreased inhibition of the mitochondrial respiration.

Compounds I of the present invention can be synthesized as outlined in the synthetic route below.
In scheme 1, A and Ar are as defined above. R′ is either R 1 or is a precursor of R 1 .
Compound (I′), which is either the desired product (I) or a precursor thereof, can be obtained by nitrating the aryl or hetaryl moiety A-H of an azabicycloheptane (II). Reduction of the nitro group and reaction of the formed amino functionality with a suitable sulfonic acid derivative provides compound (I′) (steps (i), (ii) and (iii)). Alternatively, the aryl or hetaryl moiety A-H of the azabicycloheptane (II) is brominated and then reacted with a suitable sulfonic acid derivative.
The reaction of step (i) takes place under the reaction conditions which are customary for a nitration reaction on an aromatic radical and which are described, for example, in Jerry March, Advanced Organic Chemistry, John Wiley, 3 rd edition, page 468ff, Tetrahedron 1999, 55(33), pp. 10243-10252, J. Med. Chem. 1997, 40(22), pp. 3679-3686 and Synthetic Communications, 1993, 23(5), pp. 591-599. For example, compound (II) is reacted with concentrated nitric acid or a nitrate, such as potassium or sodium nitrate, in the presence of concentrated sulfuric acid. The nitration reaction generally leads to the formation of different regioisomers, such as the ortho, para and meta product. Generally, the meta product I essentially is not formed. However, customarily both ortho and para products are obtained, the para product being generally the predominant species. By separating the ortho and para products, compounds of formula I, wherein A is 1,4-aryl or hetaryl as well as compounds I, wherein A is 1,2-aryl or hetaryl, are accessible via the reaction path shown in scheme 1.
In step (ii), the nitro group in (III) is reduced to an NH 2 group. Subsequently, the NH 2 group can be converted into a —NR 5′ group, in which R 5′ has the meanings different from hydrogen which are specified for R 5 . The reaction conditions which are required for step (ii) correspond to the customary conditions for reducing aromatic nitro groups which have been described extensively in the literature (see, for example, J. March, Advanced Organic Chemistry, 3rd ed., J. Wiley & Sons, New-York, 1985, p. 1183 and the literature cited in this reference). The reduction is achieved, for example, by reacting the nitro compound III with a metal such as iron, zinc or tin under acidic reaction conditions, i.e. using nascent hydrogen, or using a complex hydride such as lithium aluminum hydride or sodium borohydride, preferably in the presence of transition metal compounds of nickel or cobalt such as NiCl 2 (P(phenyl) 3 ) 2 , or COCl 2 , (see Ono et al. Chem. Ind. (London), 1983 p. 480), or using NaBH 2 S 3 (see Lalancette et al. Can. J. Chem. 49, 1971, p. 2990), with it being possible to carry out these reductions, depending on the given reagent, in substance or in a solvent or diluent. Alternatively, the reduction of VII to VIII can be carried out with hydrogen in the presence of a transition metal catalyst, e.g. using hydrogen in the presence of catalysts based on platinum, palladium, nickel, ruthenium or rhodium. The catalysts can contain the transition metal in elemental form or in the form of a complex compound, of a salt or of an oxide of the transition metal, with it being possible, for the purpose of modifying the activity, to use customary coligands, e.g. organic phosphine compounds, such as triphenylphosphine, tricyclohexylphosphine or tri-n-butylphosphines or phosphites. The catalyst is customarily employed in quantities of from 0.001 to 1 mol per mol of compound VII, calculated as catalyst metal. In a preferred variant, the reduction is effected using tin(II) chloride in analogy with the methods described in Bioorganic and Medicinal Chemistry Letters, 2002, 12(15), pp. 1917-1919 and J. Med. Chem. 2002, 45(21), pp. 4679-4688. The reaction of VII with tin(II) chloride is preferably carried out in an inert organic solvent, preferably an alcohol such as methanol, ethanol, isopropanol or butanol.
Step (iii) is preferably carried out in the presence of a base, according to standard procedures in the art. In the reaction depicted in the above scheme, step (iii) takes place under the reaction conditions which are customary for preparing arylsulfonamide compounds or arylsulfonic esters, respectively, and which are described, for example, in J. March, Advanced Organic Chemistry, 3 rd edition, John Wiley & Sons, New York, 1985 p 444 and the literature cited therein, European J. Org. Chem. 2002 (13), pp. 2094-2108, Tetrahedron 2001, 57 (27) pp. 5885-5895, Bioorganic and Medicinal Chemistry Letters, 2000, 10(8), pp. 835-838 and Synthesis 2000 (1), pp. 103-108. The reaction customarily takes place in an inert solvent, for example in an ether, such as diethyl ether, diisopropyl ether, methyl tert-butyl ether or tetrahydrofuran, a halohydrocarbon, such as dichloromethane, an aliphatic or cycloaliphatic hydrocarbon, such as pentane, hexane or cyclohexane, or an aromatic hydrocarbon, such as toluene, xylene, cumene and the like, or in a mixture of the abovementioned solvents. The reaction with Cl—SO 2 —Ar is customarily carried out in the presence of an auxiliary base. Suitable bases are inorganic bases, such as sodium carbonate or potassium carbonate, or sodium hydrogencarbonate or potassium hydrogencarbonate, and organic bases, for example trialkylamines, such as triethylamine, or pyridine compounds, such as pyridine, lutidine and the like. The latter compounds can at the same time serve as solvents. The auxiliary base is customarily employed in at least equimolar quantities, based on the amine compound II.
Instead of the nitration step (i), the compounds I′ are also accessible by bromination of compound (II). The bromo substituent of the A group may then be replaced by reacting with an appropriate sulfonamide ArSO 2 NH 2 , e.g. under microwave conditions. Pd, especially Pd(0), or Cu catalysts may also be used for coupling (see, e.g. Org. Lett. 2000, 2, 1101; J. Am. Chem. Soc. 2002, 124, 6043; Org. Lett. 2003, 5, 4373; Tetrahedron Lett. 2003, 44, 3385). This reaction path is especially useful in cases where the corresponding sulfonyl chloride is not available. Alternatively, the bromo substituent may be replaced by an amino substituent, e.g. by reacting with benzophenone imine in the presence of a Pd catalyst (see, e.g. J. Org. Chem. 2000, 65, 2612). The aminoaryl or hetaryl compound may then be subjected to the sulfonation of step (iii).
If R′ is allyl, the allyl group can be cleaved to obtain a compound wherein R′ is hydrogen. The cleavage of the allyl group is achieved, for example, by reacting I [R′=allyl] with an allyl trapping agent, such as mercaptobenzoic acid or 1,3-dimethylbarbituric acid, in the presence of catalytic quantities of palladium (0) compounds or palladium compounds which are able to form a palladium(0) compound under reaction conditions, e.g. palladium dichloride, tetrakis(triphenylphosphine)palladium(0) or tris(dibenzylideneacetone)dipalladium(0), advantageously in combination with phosphine ligands, e.g. triarylphosphines, such as triphenylphosphine, trialkylphosphines, such as tributylphosphine, and cycloalkylphosphines, such as tricyclohexylphosphine, and especially with phosphine chelate ligands, such as 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl or 1,4-bis(diphenylphosphino)butane, using methods known from the literature (with regard to eliminating N-allyl in the presence of mercaptobenzoic acid, see WO 94/24088; with regard to eliminating in the presence of 1,3-dimethylbarbituric acid, see J. Am. Chem. Soc. 2001, 123 (28), pp. 6801-6808 and J. Org. Chem 2002, 67(11) pp. 3718-3723). Alternatively, the cleavage of N-allyl can also be effected by reacting in the presence of rhodium compounds, such as tris(triphenylphosphine)chlororhodium(I), using methods known from the literature (see J. Chem. Soc., Perkin Transaction I: Organic and Bio-Organic Chemistry 1999 (21) pp. 3089-3104 and Tetrahedron Asymmetry 1997, 8(20), pp. 3387-3391).
If R′ is benzyl, this substituent may also be cleaved to obtain a compound I′ wherein R′ is H. The reaction conditions for the cleavage are known in the art. Typically, the benzyl group is removed by a hydrogenation reaction in the presence of a suitable Pd catalyst, such as Pd on carbon or palladium hydroxide.
R′ can also be a protective group. The protective group may be removed to yield a compound I′ wherein R′ is H. Suitable protective groups are known in the art and are, for example, selected from tert-butoxycarbonyl (boc), benzyloxycarbonyl (Cbz), 9-fluorenylmethoxycarbonyl (Fmoc), triphenylmethyl (Trt) and nitrobenzenesulfenyl (Nps). A preferred protective group is boc. The protective groups can be removed by known methods, such as treatment of the protected amine with an acid, e.g halogen acid, such as HCl or HBr, or trifluoroacetic acid, or by hydrogenation, optionally in the presence of a Pd catalyst.
The resulting compound [R′═H] can then be reacted, in a known manner, in the sense of an alkylation, with a compound R 1 —X. In this compound, R 1 is C 1 -C 4 -alkyl, C 3 -C 6 -cycloalkyl, C 1 -C 4 -haloalkyl, C 1 -C 4 -alkoxy-C 1 -C 4 -alkyl or C 3 -C 6 -cycloalkyl-C 1 -C 4 -alkyl and X is a nucleophilically displaceable leaving group, e.g. halogen, trifluoroacetate, alkylsulfonate, arylsulfonate, alkyl sulfate and the like. The reaction conditions which are required for the alkylation have been adequately disclosed, e.g. in Bioorganic and Medicinal Chemistry Lett. 2002, 12(7), pp. 2443-2446 and also 2002, 12(5), pp. 1917-1919.
The alkylation can also be achieved, in the sense of a reductive amination, by reacting the compound I′, wherein R′═H, with a suitable ketone or aldehyde in the presence of a reducing agent, e.g. in the presence of a borohydride such as sodium borohydride, sodium cyanoborohydride or sodium triacetoxyborohydride. The skilled person is familiar with the reaction conditions which are required for a reductive amination, e.g. from Bioorganic and Medicinal Chemistry Lett. 2002, 12(5), pp. 795-798 and 12(7) pp. 1269-1273.
In case R′ is hydrogen, the resulting sulfonamide can further be reacted with an acyl halide to obtain a compound of the formula I wherein R 1 is C 1 -C 3 -alkylcarbonyl. The carbonyl group in these compounds can be reduced, e.g. with diborane or lithium aluminium hydride, to obtain compounds of the general formula I, wherein R 1 is C 2 -C 4 -alkyl. The carbonyl group can also be reacted with a fluorinating agent to obtain a compound I wherein R 1 is 1,1-difluoroalkyl. Acylation and reduction can be achieved by standard methods, which are discussed in Jerry March, Advanced Organic Chemistry, 3rd ed. J. Wiley & Sons, New York 1985, p. 370 and 373 (acylation) and p. 1099 f. and in the literature cited in this publication (with regard to acylation, see also Synth. Commun. 1986, 16, p. 267, and with regard to reduction, see also J. Heterocycl. Chem. 1979, 16, p. 1525).
The substituent Ar can be varied by either using different sulfonyl chlorides or by modifying the substituents of the cyclic group Ar after the formation of the sulfonylamide by known methods. For example, a bromine substituent of the Ar group may be replaced by an N-bound pyrrolidinyl group according to the procedure described in Tetrahedron Asym. 1999, 10, 1831. A bromine substituent of the Ar group may be replaced by an isopropenyl group according to a Stille coupling where the bromo compound is reacted with an alkenyl tributyl stannate in the presence of an appropriate Pd coupling catalyst, e.g. tetrakistriphenylphosphine palladium(0) (see, e.g. Tetrahedron, 2003, 59(34), 6545 and Bioorg. Med. Chem. 1999, 7(5), 665). The isopropenyl group may then be converted into the isopropyl group by known hydrogenation methods.
Starting compound (II) can be obtained according to following scheme 2 (see WO 94/00458, WO 00/23423 and Drugs and Future, 1998, 23(2), 191)
In scheme 2, A has the meanings as defined above. R 2 is H or a suitable substituent, such as halogen. If R 2 is Br, the resulting compound (II) can be subjected to step (v) without further reaction.
In step (vi), an aryl or hetaryl aldehyde is reacted with vinyl magnesium chloride to yield the enol (VII). (VIII), obtained via HCl addition and dehydration, is reacted with allyl amine to provide (IX) which is converted in a photochemical [2+2]-cycloaddition reaction into the azabicycloheptane (II). Compound (IX) having E-configuration (as shown in scheme 2) yields essentially the exo enantiomers, whereas the corresponding Z-isomer of (IX) provides essentially the endo isomers. The Z-isomer of (IX) can be obtained by reacting in step (vi) with aryl lithium species to form the hydroxylated species, which is then dehydrated and hydrogenated to give the Z-compound.
The exo and the endo enantiomers, respectively, can be separated by methods known in the art. For instance, the mixture of enantiomers may be treated with enantiomerically pure acids, e.g. with (+) or (−)-ditoluoyltartrate, to yield diastereomeric salts. The latter can be separated by standard separation methods such as chromatography, crystallization and the like. Alternatively, the mixture can be separated by means of a chiral chromatographic column.
Compound (II), where R′ is H (as obtained according to scheme 2) can, if desired, be converted into an N-substituted compound by reacting with a suitable alkylating or acylating agent, as discussed above, before being subjected to the reaction steps of scheme 1.
If not indicated otherwise, the above-described reactions are generally carried out in a solvent at temperatures between room temperature and the boiling temperature of the solvent employed. Alternatively, the activation energy which is required for the reaction can be introduced into the reaction mixture using microwaves, something which has proved to be of value, in particular, in the case of the reactions catalyzed by transition metals (with regard to reactions using microwaves, see Tetrahedron 2001, 57, p. 9199 ff. p. 9225 ff. and also, in a general manner, “Microwaves in Organic Synthesis”, André Loupy (Ed.), Wiley-VCH 2002.
The sulfonylchlorides Cl—SO 2 —Ar are either commercially available or can be prepared according to standard synthetic methods. Sulfonylchlorides containing a fluorinated radical R a may be prepared by different synthetic routes, e.g. by reacting suitable hydroxy or oxo precursor (e.g. a compound Cl—SO 2 —Ar, carrying a hydroxy or oxo substituted radical) with fluorinating reagents like DAST (diethylaminosulfurtrifluoride), morpholine-DAST, deoxofluor (bis(2-methoxyethyl)aminosulfur trifluoride), Ishikawa's reagent (N,N-diethyl-(1,1,2,3,3,3-hexafluoropropyl)amine; Journal of Fluorine Chemistry, 1989, 43, 371-377). More conventionally, the hydroxy group of an aromatic compound which carries a hydroxy substituted radical but not a chlorosulfonyl group, is transformed into a leaving group which is then replace by a fluoride ion (J. Org. Chem., 1994, 59, 2898-22901; Tetrahedron Letters, 1998, 7305-6; J. Org. Chem., 1998, 63, 9587-9589, Synthesis, 1987, 920-21)). Sub-sequent direct chlorosulfonylation with chlorosulfonic acid (Heterocycles, 2001, 55, 9, 1789-1803; J. Org. Chem., 2000, 65, 1399-1406) or a two step process preparing first the sulfonic acid derivatives which are then transformed to the sulfonylchlorides with e.g. chlorosulfonic acid, phosphorous pentachloride (Eur. J. Med. Chem., 2002, 36, 809-828) and the like, yields the desired sulfonylchloride (Tetrahedron Letters, 1991, 33, 50 7787-7788)) Sulfonylchlorides may also be prepared by diazotation of suitable amine precursor Ar—NH 2 with sodium nitrite under acidic conditions and reaction with sulfur dioxide in acetic acid (scheme (iii); J. Org. Chem., 1960, 25, 1824-26;); by oxidation of suitable heteroaryl-thiols HS—Ar or heteroaryl-benzyl-thioethers C 6 H 5 —CH 2 —S—Ar with chlorine (Synthesis, 1998, 36-38; J. Am. Chem. Soc., 1950, 74, 4890-92;) directly to the corresponding sulfonyl chlorides. The further are known in the art or may be prepared by standard methods. E.g. mercapto-pyrimidines or pyrimidinyl-benzylthioether precursors can e.g. be prepared according to literature (Chemische Berichte, 1960, 1208-11; Chemische Berichte, 1960, 95, 230-235; Collection Czechoslow. Chem. Comm., 1959, 24, 1667-1671; Austr. J. Chem., 1966, 19, 2321-30; Chemiker-Zeitung, 101, 6, 1977, 305-7; Tetrahedron, 2002, 58, 887-890; Synthesis, 1983, 641-645).
In the following schemes 3 to 5 several routes are shown which are suitable to prepare benzenesulfonyl chlorides carrying a fluorinated propyl radical.
The 4-(1,1-difluoropropan-2-yl)benzene-1-sulfonyl chloride intermediate can be prepared from the commercially available 2-phenylpropanoic acid. In the first step a) the 2-phenylpropanic acid is converted to the alkyl ester by esterification with an alcohol (e.g. methanol or ethanol) under acid catalysis (e.g. HCl, SO 2 Cl 2 ). The ester can be reduced to the corresponding 2-phenyl propanal by a reducing agent such as DIBAL (diisobutylaluminium hydride). The aldehyde is converted to the 1,1-difluoro-2-propyl derivative by reaction with a suitable fluorinating reagent like DAST (diethylaminosulfurtrifluoride), morpholine-DAST, deoxofluor (bis(2-methoxyethyl)aminosulfur trifluoride), Ishikawa's reagent (N,N-diethyl-(1,1,2,3,3,3-hexafluoropropyl)amine: Journal of Fluorine Chemistry, 1989, 43, 371-377) (step b). The thus obtained 1,1-difluoro-2-phenylpropane can be converted into 4-(1,1-difluoro-2-propyl)benzenesulfonyl chloride by either direct chlorosulfonylation with chlorosulfonic acid (Heterocycles, 2001, 55, 9, 1789-1803; J. Org. Chem., 2000, 65, 1399-1406) (step c) or by a two step process preparing first the sulfonic acid derivatives (step d) which are then transformed to the sulfonylchlorides (step e) by reaction with e.g. chlorosulfonic acid, phosphorous pentachloride (Eur. J. Med. Chem., 2002, 36, 809-828); through diazotisation of suitable amine precursors with sodium nitrite under acidic conditions and reaction with sulfur dioxide in acetic acid (J. Org. Chem., 1960, 25, 1824-26); oxidation of suitable heteroaryl-thiols or heteroaryl-benzyl-thioethers with chlorine (Synthesis, 1998, 36-38; J. Am. Chem. Soc., 1950, 74, 4890-92) directly to the corresponding sulfonyl chlorides.
The synthesis shown in scheme 3 can also be performed using (R)-2-phenylpropanic acid and (S)-2-phenylpropanic acid respectively to give the corresponding chiral 4-(1,1-difluoropropan-2-yl)benzene-1-sulfonyl chlorides.
4-(1,1,1-Trifluoropropan-2-yl)benzene-1-sulfonyl chloride intermediate can be prepared from the commercially available 2,2,2-trifluoro-1-phenylethanone by a synthetic route shown in scheme 4. The ketone can be converted to the 3,3,3-trifluoro-2-phenylpropene by a Wittig reaction with a suitable ylide such as methylene-triphenylphosphane (prepared by reaction of methyltriphenylphosphonium halide and a suitable base such as lithium diisopropylamide or potassium tert-butoxide) or according to a Horner-Emmons reaction by reacting the ketone with a suitable phosphonate such as diethyl methylphosphonate and a suitable base such as lithium diisopropylamide or potassium tert-butoxide. The thus obtained 3,3,3-trifluoro-2-phenylpropene can then be reduced to the saturated alkane by catalytic hydrogenation (eg Pd—C) followed by conversion to the sulfonyl chloride by the methods described in scheme 3.
The synthesis of scheme 4 can also be performed using a chiral catalyst for the alkene hydrogenation to allow the preparation of the corresponding chiral 4-(1,1,1-triifluoropropan-2-yl)benzene-1-sulfonyl chlorides.
The 4-(1,1,1-trifluoropropan-2-yl)benzene-1-sulfonyl chloride can be also prepared from the commercially available 1-phenyl-ethanone by a four step procedure as shown in scheme 5. The ketone can be converted to the trifluoromethyl hydroxyl intermediate by reaction with trimethyl-trifluoromethyl-silane (Journal of Organic Chemistry, 2000, 65, 8848-8856; Journal of Fluorine Chemistry, 2003, 122, 243-246) which can then be converted to the trifluoromethyl bromide (Journal of the American Chemical Society, 1987, 109, 2435-4). Dehalogenation by catalytic hydrogenation (eg Pd—C) can then be followed by conversion to the sulfonyl chloride by the methods discussed above.
Examples of solvents which can be used are ethers, such as diethyl ether, diisopropyl ether, methyl tert-butyl ether or tetrahydrofuran, aprotic polar solvent, such as dimethylformamide, dimethyl sulfoxide, dimethoxyethane, and acetonitrile, aromatic hydrocarbons, such as toluene and xylene, ketones, such as acetone or methyl ethyl ketone, halohydrocarbons, such as dichloromethane, trichloromethane and dichloroethane, esters, such as ethyl acetate and methyl butyrate, carboxylic acids, such as acetic acid or propionic acid, and alcohols, such as methanol, ethanol, n-propanol, isopropanol, n-butanol, isobutanol, 2-butanol and tert.-butanol.
If desired, it is possible for a base to be present in order to neutralize protons which are released in the reactions. Suitable bases include inorganic bases, such as sodium carbonate, potassium carbonate, sodium hydrogen carbonate or potassium hydrogen carbonate, and, in addition, alkoxides, such as sodium methoxide or sodium ethoxide, alkali metal hydrides, such as sodium hydride, and also organometallic compounds, such as butyllithium compounds or alkylmagnesium compounds, or organic nitrogen bases, such as triethylamine or pyridine. The latter compounds can at the same time serve as solvents.
The crude product is isolated in a customary manner, for example by filtering, distilling off the solvent or extracting from the reaction mixture, etc. The resulting compounds can be purified in a customary manner, for example by means of recrystallizing from a solvent, by means of chromatography or by means of converting into an acid addition salt.
The acid addition salts are prepared in a customary manner by mixing the free base with a corresponding acid, where appropriate in solution in an organic solvent, for example a lower alcohol, such as methanol, ethanol or propanol, an ether, such as methyl tert-butyl ether or diisopropyl ether, a ketone, such as acetone or methyl ethyl ketone, or an ester, such as ethyl acetate.
The compounds according to the invention of the formula I are surprisingly highly selective dopamine D 3 receptor ligands which, because of their low affinity for other receptors such as D 1 receptors, D 4 receptors, α1-adrenergic and/or α2-adrenergic receptors, muscarinergic receptors, histamine receptors, opiate receptors and, in particular, dopamine D 2 receptors, give rise to fewer side-effects than do the classic neuroleptics, which are D 2 receptor antagonists. A compound of the invention can be a dopamine D 3 receptor agonist, including partial agonistic activity, or a dopamine D 3 receptor antagonist, including partial antagonistic activity.
The high affinity of the compounds according to the invention for D 3 receptors is reflected in very low in-vitro receptor binding constants (K i (D 3 ) values) of as a rule less than 50 nM (nmol/l), preferably of less than 10 nM and, in particular of less than 5 nM. The displacement of [ 125 I]-iodosulpride can, for example, be used in receptor binding studies for determining binding affinities for D 3 receptors.
The selectivity of the compounds according to the invention, i.e. the ratio K i (D 2 )/K i (D 3 ) of the receptor binding constants, is as a rule at least 50, preferably at least 100, even better at least 150. The displacement of [ 3 H]SCH23390, [ 125 I]-iodosulpride or [ 125 I]-spiperone can be used, for example, for carrying out receptor binding studies on D 1 , D 2 and D 4 receptors.
Because of their binding profile, the compounds can be used for treating diseases which respond to dopamine D 3 receptor ligands (or which are susceptible to treatment with a dopamine D 3 receptor ligand, respectively), i.e. they are effective for treating those medical disorders or diseases in which exerting an influence on (modulating) the dopamine D 3 receptors leads to an improvement in the clinical picture or to the disease being cured. Examples of these diseases are disorders or diseases of the central nervous system.
Disorders or diseases of the central nervous system are understood as meaning disorders which affect the spinal chord and, in particular, the brain. Within the meaning of the invention, the term “disorder” denotes disturbances and/or anomalies which are as a rule regarded as being pathological conditions or functions and which can manifest themselves in the form of particular signs, symptoms and/or malfunctions. While the treatment according to the invention can be directed toward individual disorders, i.e. anomalies or pathological conditions, it is also possible for several anomalies, which may be causatively linked to each other, to be combined into patterns, i.e. syndromes, which can be treated in accordance with the invention.
The disorders which can be treated in accordance with the invention are, in particular, psychiatric and neurological disturbances. These disturbances include, in particular, organic disturbances, including symptomatic disturbances, such as psychoses of the acute exogenous reaction type or attendant psychoses of organic or exogenous cause, e.g., in association with metabolic disturbances, infections and endocrinopathogies; endogenous psychoses, such as schizophrenia and schizotype and delusional disturbances; affective disturbances, such as depressions, mania and/or manic-depressive conditions; and also mixed forms of the above-described disturbances; neurotic and somatoform disturbances and also disturbances in association with stress; dissociative disturbances, e.g. loss of consciousness, clouding of consciousness, double consciousness and personality disturbances; disturbances in attention and waking/sleeping behavior, such as behavioral disturbances and emotional disturbances whose onset lies in childhood and youth, e.g. hyperactivity in children, intellectual deficits, in particular attention disturbances (attention deficit disorders), memory disturbances and cognitive disturbances, e.g. impaired learning and memory (impaired cognitive function), dementia, narcolepsy and sleep disturbances, e.g. restless legs syndrome; development disturbances; anxiety states, delirium; sexlife disturbances, e.g. impotence in men; eating disturbances, e.g. anorexia or bulimia; addiction; and other unspecified psychiatric disturbances.
The disorders which can be treated in accordance with the invention also include Parkinson's disease and epilepsy and, in particular, the affective disturbances connected thereto.
The addiction diseases include psychic disorders and behavioral disturbances which are caused by the abuse of psychotropic substances, such as pharmaceuticals or narcotics, and also other addiction diseases, such as addiction to gaming (impulse control disorders not elsewhere classified). Examples of addictive substances are: opioids (e.g. morphine, heroin and codeine), cocaine; nicotine; alcohol; substances which interact with the GABA chloride channel complex, sedatives, hypnotics and tranquilizers, for example benzodiazepines; LSD; cannabinoids; psychomotor stimulants, such as 3,4-methylenedioxy-N-methylamphetamine (ecstasy); amphetamine and amphetamine-like substances such as methylphenidate and other stimulants including caffeine. Addictive substances which come particularly into consideration are opioids, cocaine, amphetamine or amphetamine-like substances, nicotine and alcohol.
With regard to the treatment of addiction diseases, particular preference is given to those compounds according to the invention of the formula I which themselves do not possess any psychotropic effect. This can also be observed in a test using rats, which, after having been administered compounds which can be used in accordance with the invention, reduce their self administration of psychotropic substances, for example cocaine.
According to another aspect of the present invention, the compounds according to the invention are suitable for treating disorders whose causes can at least partially be attributed to an anomalous activity of dopamine D 3 receptors.
According to another aspect of the present invention, the treatment is directed, in particular, toward those disorders which can be influenced, within the sense of an expedient medicinal treatment, by the binding of preferably exogeneously administered binding partners (ligands) to dopamine D 3 receptors.
The diseases which can be treated with the compounds according to the invention are frequently characterized by progressive development, i.e. the above-described conditions change over the course of time; as a rule, the severity increases and conditions may possibly merge into each other or other conditions may appear in addition to those which already exist.
The compounds according to the invention can be used to treat a large number of signs, symptoms and/or malfunctions which are connected with the disorders of the central nervous system and, in particular, the abovementioned conditions. These signs, symptoms and/or malfunctions include, for example, a disturbed relationship to reality, lack of insight and ability to meet customary social norms or the demands made by life, changes in temperament, changes in individual drives, such as hunger, sleep, thirst, etc., and in mood, disturbances in the ability to observe and combine, changes in personality, in particular emotional lability, hallucinations, ego-disturbances, distractedness, ambivalence, autism, depersonalization and false perceptions, delusional ideas, chanting speech, lack of synkinesia, short-step gait, flexed posture of trunk and limbs, tremor, poverty of facial expression, monotonous speech, depressions, apathy, impeded spontaneity and decisiveness, impoverished association ability, anxiety, nervous agitation, stammering, social phobia, panic disturbances, withdrawal symptoms in association with dependency, maniform syndromes, states of excitation and confusion, dysphoria, dyskinetic syndromes and tic disorders, e.g. Huntington's chorea and Gilles-de-la-Tourette's syndrome, vertigo syndromes, e.g. peripheral positional, rotational and oscillatory vertigo, melancholia, hysteria, hypochondria and the like.
Within the meaning of the invention, a treatment also includes a preventive treatment (prophylaxis), in particular as relapse prophylaxis or phase prophylaxis, as well as the treatment of acute or chronic signs, symptoms and/or malfunctions. The treatment can be orientated symptomatically, for example as the suppression of symptoms. It can be effected over a short period, be orientated over the medium term or can be a long-term treatment, for example within the context of a maintenance therapy.
Therefore the compounds according to the invention are preferentially suitable for treating diseases of the central nervous system, in particular for treating affective disorders; neurotic disturbances, stress disturbances and somatoform disturbances and psychoses, and, in particular, for treating schizophrenia and depression. Because of their high selectivity with regard to the D 3 receptor, the compounds I according to the invention are also suitable for treating disturbances of kidney function, in particular disturbances of kidney function which are caused by diabetes mellitus (see WO 00/67847) and, especially, diabetic nephropathy.
Within the context of the treatment, the use according to the invention of the described compounds involves a method. In this method, an effective quantity of one or more compounds, as a rule formulated in accordance with pharmaceutical and veterinary practice, is administered to the individual to be treated, preferably a mammal, in particular a human being, productive animal or domestic animal. Whether such a treatment is indicated, and in which form it is to take place, depends on the individual case and is subject to medical assessment (diagnosis) which takes into consideration signs, symptoms and/or malfunctions which are present, the risks of developing particular signs, symptoms and/or malfunctions, and other factors.
As a rule, the treatment is effected by means of single or repeated daily administration, where appropriate together, or alternating, with other active compounds or active compound-containing preparations such that a daily dose of preferably from about 0.1 to 1000 mg/kg of bodyweight, in the case of oral administration, or of from about 0.1 to 100 mg/kg of bodyweight, in the case of parenteral administration, is supplied to an individual to be treated.
The invention also relates to the production of pharmaceutical compositions for treating an individual, preferably a mammal, in particular a human being, productive animal or domestic animal. Thus, the ligands are customarily administered in the form of pharmaceutical compositions which comprise a pharmaceutically acceptable excipient together with at least one compound according to the invention and, where appropriate, other active compounds. These compositions can, for example, be administered orally, rectally, transdermally, subcutaneously, intravenously, intramuscularly or intranasally.
Examples of suitable pharmaceutical formulations are solid medicinal forms, such as powders, granules, tablets, in particular film tablets, lozenges, sachets, cachets, sugar-coated tablets, capsules, such as hard gelatin capsules and soft gelatin capsules, suppositories or vaginal medicinal forms, semisolid medicinal forms, such as ointments, creams, hydrogels, pastes or plasters, and also liquid medicinal forms, such as solutions, emulsions, in particular oil-in-water emulsions, suspensions, for example lotions, injection preparations and infusion preparations, and eyedrops and eardrops. Implanted release devices can also be used for administering inhibitors according to the invention. In addition, it is also possible to use liposomes or microspheres.
When producing the compositions, the compounds according to the invention are optionally mixed or diluted with one or more excipients. Excipients can be solid, semisolid or liquid materials which serve as vehicles, carriers or medium for the active compound.
Suitable excipients are listed in the specialist medicinal monographs. In addition, the formulations can comprise pharmaceutically acceptable carriers or customary auxiliary substances, such as glidants; wetting agents; emulsifying and suspending agents; preservatives; antioxidants; antiirritants; chelating agents; coating auxiliaries; emulsion stabilizers; film formers; gel formers; odor masking agents; taste corrigents; resin; hydrocolloids; solvents; solubilizers; neutralizing agents; diffusion accelerators; pigments; quaternary ammonium compounds; refatting and overfatting agents; raw materials for ointments, creams or oils; silicone derivatives; spreading auxiliaries; stabilizers; sterilants; suppository bases; tablet auxiliaries, such as binders, fillers, glidants, disintegrants or coatings; propellants; drying agents; opacifiers; thickeners; waxes; plasticizers and white mineral oils. A formulation in this regard is based on specialist knowledge as described, for example, in Fiedler, H. P., Lexikon der Hilfsstoffe für Pharmazie, Kosmetik und angrenzende Gebiete [Encyclopedia of auxiliary substances for pharmacy, cosmetics and related fields], 4 th edition, Aulendorf: ECV-Editio-Kantor-Verlag, 1996.
The following examples serve to explain the invention without limiting it.
The compounds were either characterized via proton-NMR in d 4 -methanol, d 6 -dimethylsulfoxid or d-chloroform on a 400 MHz or 500 MHz NMR instrument (Bruker AVANCE), or by mass spectrometry, generally recorded via HPLC-MS in a fast gradient on C18-material (electrospray-ionisation (ESI) mode), or melting point.
The magnetic nuclear resonance spectral properties (NMR) refer to the chemical shifts (6) expressed in parts per million (ppm). The relative area of the shifts in the 1 H NMR spectrum corresponds to the number of hydrogen atoms for a particular functional type in the molecule. The nature of the shift, as regards multiplicity, is indicated as singlet (s), broad singlet (s. br.), doublet (d), broad doublet (d br.), triplet (t), broad triplet (t br.), quartet (q), quintet (quint.) and multiplet (m).

IV. Biological Investigations
Receptor Binding Studies:
The substance to be tested was either dissolved in methanol/Chremophor® (BASF-AG) or in dimethyl sulfoxide and then diluted with water to the desired concentration.
Dopamine D 3 Receptor:
The assay mixture (0.250 ml) was composed of membranes derived from ˜10 6 HEK-293 cells possessing stably expressed human dopamine D 3 receptors, 0.1 nM [ 125 I]-iodosulpride and incubation buffer (total binding) or, in addition, test substance (inhibition curve) or 1 μM spiperone (nonspecific binding). Each assay mixture was run in triplicate.
The incubation buffer contained 50 mM tris, 120 mM NaCl, 5 mM KCl, 2 mM CaCl 2 , 2 mM MgCl 2 and 0.1% bovine serum albumin, 10 μM quinolone and 0.1% ascorbic acid (prepared fresh daily). The buffer was adjusted to pH 7.4 with HCl.
Dopamine D 2L Receptor:
The assay mixture (1 ml) was composed of membranes from ˜106 HEK-293 cells possessing stably expressed human dopamine D 2L receptors (long isoform) and 0.01 nM [ 125 I]iodospiperone and incubation buffer (total binding) or, in addition, test substance (inhibition curve) or 1 μM haloperidol (nonspecific binding). Each assay mixture was run in triplicate.
The incubation buffer contained 50 mM tris, 120 mM NaCl, 5 mM KCl, 2 mM CaCl 2 , 2 mM MgCl 2 and 0.1% bovine serum albumin. The buffer was adjusted to pH 7.4 with HCl.
Measurement and Analysis:
After having been incubated at 25° C. for 60 minutes, the assay mixtures were filtered through a Whatman GF/B glass fiber filter under vacuum using a cell collecting device. The filters were transferred to scintillation viols using a filter transfer system. After 4 ml of Ultima Gold® (Packard) have been added, the samples were shaken for one hour and the radioactivity was then counted in a Beta-Counter (Packard, Tricarb 2000 or 2200CA). The cpm values were converted into dpm using a standard quench series and the program belonging to the instrument.
The inhibition curves were analyzed by means of iterative nonlinear regression analysis using the Statistical Analysis System (SAS) which is similar to the “LIGAND” program described by Munson and Rodbard.
The results of the receptor binding studies are expressed as receptor binding constants K i (D 2 ) and K i (D 3 ), respectively, as herein before described, and given in table 1.
In these tests, the compounds according to the invention exhibit very good affinities for the D 3 receptor (<10 nM, frequently <5 nM) and bind selectively to the D 3 receptor.
The results of the binding tests are given in table 1.

7.Description:
(en)BACKGROUND OF THE INVENTION
The present invention relates to novel azabicycloheptyl compounds. The compounds possess valuable therapeutic properties and are suitable, in particular, for treating diseases that respond to modulation of the dopamine D 3 receptor.
Neurons obtain their information by way of G protein-coupled receptors, inter alia. A large number of substances exert their effect by way of these receptors. One of them is dopamine. Confirmed findings exist with regard to the presence of dopamine and its physiological function as a neurotransmitter. Disorders in the dopaminergic transmitter system result in diseases of the central nervous system which include, for example, schizophrenia, depression and Parkinson's disease. These diseases, and others, are treated with drugs which interact with the dopamine receptors.
Up until 1990, two subtypes of dopamine receptor had been clearly defined pharmacologically, namely the D 1 and D 2 receptors. More recently, a third subtype was found, namely the D 3 receptor which appears to mediate some effects of antipsychotics and antiparkinsonians (J. C. Schwartz et al., The Dopamine D 3 Receptor as a Target for Antipsychotics, in Novel Antipsychotic Drugs, H. Y. Meltzer, Ed. Raven Press, New York 1992, pages 135-144; M. Dooley et al., Drugs and Aging 1998, 12, 495-514, J. N. Joyce, Pharmacology and Therapeutics 2001, 90, pp. 231-59 “The Dopamine D 3 Receptor as a Therapeutic Target for Antipsychotic and Antiparkinsonian Drugs”).
Since then, the dopamine receptors have been divided into two families. On the one hand, there is the D 2 group, consisting of D 2 , D 3 and D 4 receptors, and, on the other hand, the D 1 group, consisting of D 1 and D 5 receptors. Whereas D 1 and D 2 receptors are widely distributed, D 3 receptors appear to be expressed regioselectively. Thus, these receptors are preferentially to be found in the limbic system and the projection regions of the mesolimbic dopamine system, especially in the nucleus accumbens, but also in other regions, such as the amygdala. Because of this comparatively regioselective expression, D 3 receptors are regarded as being a target having few side-effects and it is assumed that while a selective D 3 ligand would have the properties of known antipsychotics, it would not have their dopamine D 2 receptor-mediated neurological side-effects (P. Sokoloff et al., Localization and Function of the D 3 Dopamine Receptor, Arzneim. Forsch./Drug Res. 42(1), 224 (1992); P. Sokoloff et al. Molecular Cloning and Characterization of a Novel Dopamine Receptor (D 3 ) as a Target for Neuroleptics, Nature, 347, 146 (1990)).
Compounds having an affinity for the dopamine D 3 receptor have been described in the prior art on various occasions, e.g. in WO 95/04713, WO 96/23760, WO 97/45503, WO98/27081 and WO 99/58499. Some of these compounds possess moderate affinities and or selectivities for the dopamine D 3 receptor. They have therefore been proposed as being suitable for treating diseases of the central nervous system. Some of the compounds described in these publications possess a pyrrolidinylphenyl structure. Unfortunately their affinity and selectivity towards the D 3 receptor or their pharmacological profile are not satisfactory. Consequently there is an ongoing need to provide new compounds, which either have an high affinity and an improved selectivity. The compounds should also have good pharmacological profile, e.g. a high brain plasma ratio, a high bioavailability, good metabolic stability, or a decreased inhibition of the mitochondrial respiration.

Compounds I of the present invention can be synthesized as outlined in the synthetic route below.
In scheme 1, A and Ar are as defined above. R′ is either R 1 or is a precursor of R 1 .
Compound (I′), which is either the desired product (I) or a precursor thereof, can be obtained by nitrating the aryl or hetaryl moiety A-H of an azabicycloheptane (II). Reduction of the nitro group and reaction of the formed amino functionality with a suitable sulfonic acid derivative provides compound (I′) (steps (i), (ii) and (iii)). Alternatively, the aryl or hetaryl moiety A-H of the azabicycloheptane (II) is brominated and then reacted with a suitable sulfonic acid derivative.
The reaction of step (i) takes place under the reaction conditions which are customary for a nitration reaction on an aromatic radical and which are described, for example, in Jerry March, Advanced Organic Chemistry, John Wiley, 3 rd edition, page 468ff, Tetrahedron 1999, 55(33), pp. 10243-10252, J. Med. Chem. 1997, 40(22), pp. 3679-3686 and Synthetic Communications, 1993, 23(5), pp. 591-599. For example, compound (II) is reacted with concentrated nitric acid or a nitrate, such as potassium or sodium nitrate, in the presence of concentrated sulfuric acid. The nitration reaction generally leads to the formation of different regioisomers, such as the ortho, para and meta product. Generally, the meta product I essentially is not formed. However, customarily both ortho and para products are obtained, the para product being generally the predominant species. By separating the ortho and para products, compounds of formula I, wherein A is 1,4-aryl or hetaryl as well as compounds I, wherein A is 1,2-aryl or hetaryl, are accessible via the reaction path shown in scheme 1.
In step (ii), the nitro group in (III) is reduced to an NH 2 group. Subsequently, the NH 2 group can be converted into a —NR 5′ group, in which R 5′ has the meanings different from hydrogen which are specified for R 5 . The reaction conditions which are required for step (ii) correspond to the customary conditions for reducing aromatic nitro groups which have been described extensively in the literature (see, for example, J. March, Advanced Organic Chemistry, 3rd ed., J. Wiley & Sons, New-York, 1985, p. 1183 and the literature cited in this reference). The reduction is achieved, for example, by reacting the nitro compound III with a metal such as iron, zinc or tin under acidic reaction conditions, i.e. using nascent hydrogen, or using a complex hydride such as lithium aluminum hydride or sodium borohydride, preferably in the presence of transition metal compounds of nickel or cobalt such as NiCl 2 (P(phenyl) 3 ) 2 , or COCl 2 , (see Ono et al. Chem. Ind. (London), 1983 p. 480), or using NaBH 2 S 3 (see Lalancette et al. Can. J. Chem. 49, 1971, p. 2990), with it being possible to carry out these reductions, depending on the given reagent, in substance or in a solvent or diluent. Alternatively, the reduction of VII to VIII can be carried out with hydrogen in the presence of a transition metal catalyst, e.g. using hydrogen in the presence of catalysts based on platinum, palladium, nickel, ruthenium or rhodium. The catalysts can contain the transition metal in elemental form or in the form of a complex compound, of a salt or of an oxide of the transition metal, with it being possible, for the purpose of modifying the activity, to use customary coligands, e.g. organic phosphine compounds, such as triphenylphosphine, tricyclohexylphosphine or tri-n-butylphosphines or phosphites. The catalyst is customarily employed in quantities of from 0.001 to 1 mol per mol of compound VII, calculated as catalyst metal. In a preferred variant, the reduction is effected using tin(II) chloride in analogy with the methods described in Bioorganic and Medicinal Chemistry Letters, 2002, 12(15), pp. 1917-1919 and J. Med. Chem. 2002, 45(21), pp. 4679-4688. The reaction of VII with tin(II) chloride is preferably carried out in an inert organic solvent, preferably an alcohol such as methanol, ethanol, isopropanol or butanol.
Step (iii) is preferably carried out in the presence of a base, according to standard procedures in the art. In the reaction depicted in the above scheme, step (iii) takes place under the reaction conditions which are customary for preparing arylsulfonamide compounds or arylsulfonic esters, respectively, and which are described, for example, in J. March, Advanced Organic Chemistry, 3 rd edition, John Wiley & Sons, New York, 1985 p 444 and the literature cited therein, European J. Org. Chem. 2002 (13), pp. 2094-2108, Tetrahedron 2001, 57 (27) pp. 5885-5895, Bioorganic and Medicinal Chemistry Letters, 2000, 10(8), pp. 835-838 and Synthesis 2000 (1), pp. 103-108. The reaction customarily takes place in an inert solvent, for example in an ether, such as diethyl ether, diisopropyl ether, methyl tert-butyl ether or tetrahydrofuran, a halohydrocarbon, such as dichloromethane, an aliphatic or cycloaliphatic hydrocarbon, such as pentane, hexane or cyclohexane, or an aromatic hydrocarbon, such as toluene, xylene, cumene and the like, or in a mixture of the abovementioned solvents. The reaction with Cl—SO 2 —Ar is customarily carried out in the presence of an auxiliary base. Suitable bases are inorganic bases, such as sodium carbonate or potassium carbonate, or sodium hydrogencarbonate or potassium hydrogencarbonate, and organic bases, for example trialkylamines, such as triethylamine, or pyridine compounds, such as pyridine, lutidine and the like. The latter compounds can at the same time serve as solvents. The auxiliary base is customarily employed in at least equimolar quantities, based on the amine compound II.
Instead of the nitration step (i), the compounds I′ are also accessible by bromination of compound (II). The bromo substituent of the A group may then be replaced by reacting with an appropriate sulfonamide ArSO 2 NH 2 , e.g. under microwave conditions. Pd, especially Pd(0), or Cu catalysts may also be used for coupling (see, e.g. Org. Lett. 2000, 2, 1101; J. Am. Chem. Soc. 2002, 124, 6043; Org. Lett. 2003, 5, 4373; Tetrahedron Lett. 2003, 44, 3385). This reaction path is especially useful in cases where the corresponding sulfonyl chloride is not available. Alternatively, the bromo substituent may be replaced by an amino substituent, e.g. by reacting with benzophenone imine in the presence of a Pd catalyst (see, e.g. J. Org. Chem. 2000, 65, 2612). The aminoaryl or hetaryl compound may then be subjected to the sulfonation of step (iii).
If R′ is allyl, the allyl group can be cleaved to obtain a compound wherein R′ is hydrogen. The cleavage of the allyl group is achieved, for example, by reacting I [R′=allyl] with an allyl trapping agent, such as mercaptobenzoic acid or 1,3-dimethylbarbituric acid, in the presence of catalytic quantities of palladium (0) compounds or palladium compounds which are able to form a palladium(0) compound under reaction conditions, e.g. palladium dichloride, tetrakis(triphenylphosphine)palladium(0) or tris(dibenzylideneacetone)dipalladium(0), advantageously in combination with phosphine ligands, e.g. triarylphosphines, such as triphenylphosphine, trialkylphosphines, such as tributylphosphine, and cycloalkylphosphines, such as tricyclohexylphosphine, and especially with phosphine chelate ligands, such as 2,2′-bis(diphenylphosphino)-1,1′-binaphthyl or 1,4-bis(diphenylphosphino)butane, using methods known from the literature (with regard to eliminating N-allyl in the presence of mercaptobenzoic acid, see WO 94/24088; with regard to eliminating in the presence of 1,3-dimethylbarbituric acid, see J. Am. Chem. Soc. 2001, 123 (28), pp. 6801-6808 and J. Org. Chem 2002, 67(11) pp. 3718-3723). Alternatively, the cleavage of N-allyl can also be effected by reacting in the presence of rhodium compounds, such as tris(triphenylphosphine)chlororhodium(I), using methods known from the literature (see J. Chem. Soc., Perkin Transaction I: Organic and Bio-Organic Chemistry 1999 (21) pp. 3089-3104 and Tetrahedron Asymmetry 1997, 8(20), pp. 3387-3391).
If R′ is benzyl, this substituent may also be cleaved to obtain a compound I′ wherein R′ is H. The reaction conditions for the cleavage are known in the art. Typically, the benzyl group is removed by a hydrogenation reaction in the presence of a suitable Pd catalyst, such as Pd on carbon or palladium hydroxide.
R′ can also be a protective group. The protective group may be removed to yield a compound I′ wherein R′ is H. Suitable protective groups are known in the art and are, for example, selected from tert-butoxycarbonyl (boc), benzyloxycarbonyl (Cbz), 9-fluorenylmethoxycarbonyl (Fmoc), triphenylmethyl (Trt) and nitrobenzenesulfenyl (Nps). A preferred protective group is boc. The protective groups can be removed by known methods, such as treatment of the protected amine with an acid, e.g halogen acid, such as HCl or HBr, or trifluoroacetic acid, or by hydrogenation, optionally in the presence of a Pd catalyst.
The resulting compound [R′═H] can then be reacted, in a known manner, in the sense of an alkylation, with a compound R 1 —X. In this compound, R 1 is C 1 -C 4 -alkyl, C 3 -C 6 -cycloalkyl, C 1 -C 4 -haloalkyl, C 1 -C 4 -alkoxy-C 1 -C 4 -alkyl or C 3 -C 6 -cycloalkyl-C 1 -C 4 -alkyl and X is a nucleophilically displaceable leaving group, e.g. halogen, trifluoroacetate, alkylsulfonate, arylsulfonate, alkyl sulfate and the like. The reaction conditions which are required for the alkylation have been adequately disclosed, e.g. in Bioorganic and Medicinal Chemistry Lett. 2002, 12(7), pp. 2443-2446 and also 2002, 12(5), pp. 1917-1919.
The alkylation can also be achieved, in the sense of a reductive amination, by reacting the compound I′, wherein R′═H, with a suitable ketone or aldehyde in the presence of a reducing agent, e.g. in the presence of a borohydride such as sodium borohydride, sodium cyanoborohydride or sodium triacetoxyborohydride. The skilled person is familiar with the reaction conditions which are required for a reductive amination, e.g. from Bioorganic and Medicinal Chemistry Lett. 2002, 12(5), pp. 795-798 and 12(7) pp. 1269-1273.
In case R′ is hydrogen, the resulting sulfonamide can further be reacted with an acyl halide to obtain a compound of the formula I wherein R 1 is C 1 -C 3 -alkylcarbonyl. The carbonyl group in these compounds can be reduced, e.g. with diborane or lithium aluminium hydride, to obtain compounds of the general formula I, wherein R 1 is C 2 -C 4 -alkyl. The carbonyl group can also be reacted with a fluorinating agent to obtain a compound I wherein R 1 is 1,1-difluoroalkyl. Acylation and reduction can be achieved by standard methods, which are discussed in Jerry March, Advanced Organic Chemistry, 3rd ed. J. Wiley & Sons, New York 1985, p. 370 and 373 (acylation) and p. 1099 f. and in the literature cited in this publication (with regard to acylation, see also Synth. Commun. 1986, 16, p. 267, and with regard to reduction, see also J. Heterocycl. Chem. 1979, 16, p. 1525).
The substituent Ar can be varied by either using different sulfonyl chlorides or by modifying the substituents of the cyclic group Ar after the formation of the sulfonylamide by known methods. For example, a bromine substituent of the Ar group may be replaced by an N-bound pyrrolidinyl group according to the procedure described in Tetrahedron Asym. 1999, 10, 1831. A bromine substituent of the Ar group may be replaced by an isopropenyl group according to a Stille coupling where the bromo compound is reacted with an alkenyl tributyl stannate in the presence of an appropriate Pd coupling catalyst, e.g. tetrakistriphenylphosphine palladium(0) (see, e.g. Tetrahedron, 2003, 59(34), 6545 and Bioorg. Med. Chem. 1999, 7(5), 665). The isopropenyl group may then be converted into the isopropyl group by known hydrogenation methods.
Starting compound (II) can be obtained according to following scheme 2 (see WO 94/00458, WO 00/23423 and Drugs and Future, 1998, 23(2), 191)
In scheme 2, A has the meanings as defined above. R 2 is H or a suitable substituent, such as halogen. If R 2 is Br, the resulting compound (II) can be subjected to step (v) without further reaction.
In step (vi), an aryl or hetaryl aldehyde is reacted with vinyl magnesium chloride to yield the enol (VII). (VIII), obtained via HCl addition and dehydration, is reacted with allyl amine to provide (IX) which is converted in a photochemical [2+2]-cycloaddition reaction into the azabicycloheptane (II). Compound (IX) having E-configuration (as shown in scheme 2) yields essentially the exo enantiomers, whereas the corresponding Z-isomer of (IX) provides essentially the endo isomers. The Z-isomer of (IX) can be obtained by reacting in step (vi) with aryl lithium species to form the hydroxylated species, which is then dehydrated and hydrogenated to give the Z-compound.
The exo and the endo enantiomers, respectively, can be separated by methods known in the art. For instance, the mixture of enantiomers may be treated with enantiomerically pure acids, e.g. with (+) or (−)-ditoluoyltartrate, to yield diastereomeric salts. The latter can be separated by standard separation methods such as chromatography, crystallization and the like. Alternatively, the mixture can be separated by means of a chiral chromatographic column.
Compound (II), where R′ is H (as obtained according to scheme 2) can, if desired, be converted into an N-substituted compound by reacting with a suitable alkylating or acylating agent, as discussed above, before being subjected to the reaction steps of scheme 1.
If not indicated otherwise, the above-described reactions are generally carried out in a solvent at temperatures between room temperature and the boiling temperature of the solvent employed. Alternatively, the activation energy which is required for the reaction can be introduced into the reaction mixture using microwaves, something which has proved to be of value, in particular, in the case of the reactions catalyzed by transition metals (with regard to reactions using microwaves, see Tetrahedron 2001, 57, p. 9199 ff. p. 9225 ff. and also, in a general manner, “Microwaves in Organic Synthesis”, André Loupy (Ed.), Wiley-VCH 2002.
The sulfonylchlorides Cl—SO 2 —Ar are either commercially available or can be prepared according to standard synthetic methods. Sulfonylchlorides containing a fluorinated radical R a may be prepared by different synthetic routes, e.g. by reacting suitable hydroxy or oxo precursor (e.g. a compound Cl—SO 2 —Ar, carrying a hydroxy or oxo substituted radical) with fluorinating reagents like DAST (diethylaminosulfurtrifluoride), morpholine-DAST, deoxofluor (bis(2-methoxyethyl)aminosulfur trifluoride), Ishikawa's reagent (N,N-diethyl-(1,1,2,3,3,3-hexafluoropropyl)amine; Journal of Fluorine Chemistry, 1989, 43, 371-377). More conventionally, the hydroxy group of an aromatic compound which carries a hydroxy substituted radical but not a chlorosulfonyl group, is transformed into a leaving group which is then replace by a fluoride ion (J. Org. Chem., 1994, 59, 2898-22901; Tetrahedron Letters, 1998, 7305-6; J. Org. Chem., 1998, 63, 9587-9589, Synthesis, 1987, 920-21)). Sub-sequent direct chlorosulfonylation with chlorosulfonic acid (Heterocycles, 2001, 55, 9, 1789-1803; J. Org. Chem., 2000, 65, 1399-1406) or a two step process preparing first the sulfonic acid derivatives which are then transformed to the sulfonylchlorides with e.g. chlorosulfonic acid, phosphorous pentachloride (Eur. J. Med. Chem., 2002, 36, 809-828) and the like, yields the desired sulfonylchloride (Tetrahedron Letters, 1991, 33, 50 7787-7788)) Sulfonylchlorides may also be prepared by diazotation of suitable amine precursor Ar—NH 2 with sodium nitrite under acidic conditions and reaction with sulfur dioxide in acetic acid (scheme (iii); J. Org. Chem., 1960, 25, 1824-26;); by oxidation of suitable heteroaryl-thiols HS—Ar or heteroaryl-benzyl-thioethers C 6 H 5 —CH 2 —S—Ar with chlorine (Synthesis, 1998, 36-38; J. Am. Chem. Soc., 1950, 74, 4890-92;) directly to the corresponding sulfonyl chlorides. The further are known in the art or may be prepared by standard methods. E.g. mercapto-pyrimidines or pyrimidinyl-benzylthioether precursors can e.g. be prepared according to literature (Chemische Berichte, 1960, 1208-11; Chemische Berichte, 1960, 95, 230-235; Collection Czechoslow. Chem. Comm., 1959, 24, 1667-1671; Austr. J. Chem., 1966, 19, 2321-30; Chemiker-Zeitung, 101, 6, 1977, 305-7; Tetrahedron, 2002, 58, 887-890; Synthesis, 1983, 641-645).
In the following schemes 3 to 5 several routes are shown which are suitable to prepare benzenesulfonyl chlorides carrying a fluorinated propyl radical.
The 4-(1,1-difluoropropan-2-yl)benzene-1-sulfonyl chloride intermediate can be prepared from the commercially available 2-phenylpropanoic acid. In the first step a) the 2-phenylpropanic acid is converted to the alkyl ester by esterification with an alcohol (e.g. methanol or ethanol) under acid catalysis (e.g. HCl, SO 2 Cl 2 ). The ester can be reduced to the corresponding 2-phenyl propanal by a reducing agent such as DIBAL (diisobutylaluminium hydride). The aldehyde is converted to the 1,1-difluoro-2-propyl derivative by reaction with a suitable fluorinating reagent like DAST (diethylaminosulfurtrifluoride), morpholine-DAST, deoxofluor (bis(2-methoxyethyl)aminosulfur trifluoride), Ishikawa's reagent (N,N-diethyl-(1,1,2,3,3,3-hexafluoropropyl)amine: Journal of Fluorine Chemistry, 1989, 43, 371-377) (step b). The thus obtained 1,1-difluoro-2-phenylpropane can be converted into 4-(1,1-difluoro-2-propyl)benzenesulfonyl chloride by either direct chlorosulfonylation with chlorosulfonic acid (Heterocycles, 2001, 55, 9, 1789-1803; J. Org. Chem., 2000, 65, 1399-1406) (step c) or by a two step process preparing first the sulfonic acid derivatives (step d) which are then transformed to the sulfonylchlorides (step e) by reaction with e.g. chlorosulfonic acid, phosphorous pentachloride (Eur. J. Med. Chem., 2002, 36, 809-828); through diazotisation of suitable amine precursors with sodium nitrite under acidic conditions and reaction with sulfur dioxide in acetic acid (J. Org. Chem., 1960, 25, 1824-26); oxidation of suitable heteroaryl-thiols or heteroaryl-benzyl-thioethers with chlorine (Synthesis, 1998, 36-38; J. Am. Chem. Soc., 1950, 74, 4890-92) directly to the corresponding sulfonyl chlorides.
The synthesis shown in scheme 3 can also be performed using (R)-2-phenylpropanic acid and (S)-2-phenylpropanic acid respectively to give the corresponding chiral 4-(1,1-difluoropropan-2-yl)benzene-1-sulfonyl chlorides.
4-(1,1,1-Trifluoropropan-2-yl)benzene-1-sulfonyl chloride intermediate can be prepared from the commercially available 2,2,2-trifluoro-1-phenylethanone by a synthetic route shown in scheme 4. The ketone can be converted to the 3,3,3-trifluoro-2-phenylpropene by a Wittig reaction with a suitable ylide such as methylene-triphenylphosphane (prepared by reaction of methyltriphenylphosphonium halide and a suitable base such as lithium diisopropylamide or potassium tert-butoxide) or according to a Horner-Emmons reaction by reacting the ketone with a suitable phosphonate such as diethyl methylphosphonate and a suitable base such as lithium diisopropylamide or potassium tert-butoxide. The thus obtained 3,3,3-trifluoro-2-phenylpropene can then be reduced to the saturated alkane by catalytic hydrogenation (eg Pd—C) followed by conversion to the sulfonyl chloride by the methods described in scheme 3.
The synthesis of scheme 4 can also be performed using a chiral catalyst for the alkene hydrogenation to allow the preparation of the corresponding chiral 4-(1,1,1-triifluoropropan-2-yl)benzene-1-sulfonyl chlorides.
The 4-(1,1,1-trifluoropropan-2-yl)benzene-1-sulfonyl chloride can be also prepared from the commercially available 1-phenyl-ethanone by a four step procedure as shown in scheme 5. The ketone can be converted to the trifluoromethyl hydroxyl intermediate by reaction with trimethyl-trifluoromethyl-silane (Journal of Organic Chemistry, 2000, 65, 8848-8856; Journal of Fluorine Chemistry, 2003, 122, 243-246) which can then be converted to the trifluoromethyl bromide (Journal of the American Chemical Society, 1987, 109, 2435-4). Dehalogenation by catalytic hydrogenation (eg Pd—C) can then be followed by conversion to the sulfonyl chloride by the methods discussed above.
Examples of solvents which can be used are ethers, such as diethyl ether, diisopropyl ether, methyl tert-butyl ether or tetrahydrofuran, aprotic polar solvent, such as dimethylformamide, dimethyl sulfoxide, dimethoxyethane, and acetonitrile, aromatic hydrocarbons, such as toluene and xylene, ketones, such as acetone or methyl ethyl ketone, halohydrocarbons, such as dichloromethane, trichloromethane and dichloroethane, esters, such as ethyl acetate and methyl butyrate, carboxylic acids, such as acetic acid or propionic acid, and alcohols, such as methanol, ethanol, n-propanol, isopropanol, n-butanol, isobutanol, 2-butanol and tert.-butanol.
If desired, it is possible for a base to be present in order to neutralize protons which are released in the reactions. Suitable bases include inorganic bases, such as sodium carbonate, potassium carbonate, sodium hydrogen carbonate or potassium hydrogen carbonate, and, in addition, alkoxides, such as sodium methoxide or sodium ethoxide, alkali metal hydrides, such as sodium hydride, and also organometallic compounds, such as butyllithium compounds or alkylmagnesium compounds, or organic nitrogen bases, such as triethylamine or pyridine. The latter compounds can at the same time serve as solvents.
The crude product is isolated in a customary manner, for example by filtering, distilling off the solvent or extracting from the reaction mixture, etc. The resulting compounds can be purified in a customary manner, for example by means of recrystallizing from a solvent, by means of chromatography or by means of converting into an acid addition salt.
The acid addition salts are prepared in a customary manner by mixing the free base with a corresponding acid, where appropriate in solution in an organic solvent, for example a lower alcohol, such as methanol, ethanol or propanol, an ether, such as methyl tert-butyl ether or diisopropyl ether, a ketone, such as acetone or methyl ethyl ketone, or an ester, such as ethyl acetate.
The compounds according to the invention of the formula I are surprisingly highly selective dopamine D 3 receptor ligands which, because of their low affinity for other receptors such as D 1 receptors, D 4 receptors, α1-adrenergic and/or α2-adrenergic receptors, muscarinergic receptors, histamine receptors, opiate receptors and, in particular, dopamine D 2 receptors, give rise to fewer side-effects than do the classic neuroleptics, which are D 2 receptor antagonists. A compound of the invention can be a dopamine D 3 receptor agonist, including partial agonistic activity, or a dopamine D 3 receptor antagonist, including partial antagonistic activity.
The high affinity of the compounds according to the invention for D 3 receptors is reflected in very low in-vitro receptor binding constants (K i (D 3 ) values) of as a rule less than 50 nM (nmol/l), preferably of less than 10 nM and, in particular of less than 5 nM. The displacement of [ 125 I]-iodosulpride can, for example, be used in receptor binding studies for determining binding affinities for D 3 receptors.
The selectivity of the compounds according to the invention, i.e. the ratio K i (D 2 )/K i (D 3 ) of the receptor binding constants, is as a rule at least 50, preferably at least 100, even better at least 150. The displacement of [ 3 H]SCH23390, [ 125 I]-iodosulpride or [ 125 I]-spiperone can be used, for example, for carrying out receptor binding studies on D 1 , D 2 and D 4 receptors.
Because of their binding profile, the compounds can be used for treating diseases which respond to dopamine D 3 receptor ligands (or which are susceptible to treatment with a dopamine D 3 receptor ligand, respectively), i.e. they are effective for treating those medical disorders or diseases in which exerting an influence on (modulating) the dopamine D 3 receptors leads to an improvement in the clinical picture or to the disease being cured. Examples of these diseases are disorders or diseases of the central nervous system.
Disorders or diseases of the central nervous system are understood as meaning disorders which affect the spinal chord and, in particular, the brain. Within the meaning of the invention, the term “disorder” denotes disturbances and/or anomalies which are as a rule regarded as being pathological conditions or functions and which can manifest themselves in the form of particular signs, symptoms and/or malfunctions. While the treatment according to the invention can be directed toward individual disorders, i.e. anomalies or pathological conditions, it is also possible for several anomalies, which may be causatively linked to each other, to be combined into patterns, i.e. syndromes, which can be treated in accordance with the invention.
The disorders which can be treated in accordance with the invention are, in particular, psychiatric and neurological disturbances. These disturbances include, in particular, organic disturbances, including symptomatic disturbances, such as psychoses of the acute exogenous reaction type or attendant psychoses of organic or exogenous cause, e.g., in association with metabolic disturbances, infections and endocrinopathogies; endogenous psychoses, such as schizophrenia and schizotype and delusional disturbances; affective disturbances, such as depressions, mania and/or manic-depressive conditions; and also mixed forms of the above-described disturbances; neurotic and somatoform disturbances and also disturbances in association with stress; dissociative disturbances, e.g. loss of consciousness, clouding of consciousness, double consciousness and personality disturbances; disturbances in attention and waking/sleeping behavior, such as behavioral disturbances and emotional disturbances whose onset lies in childhood and youth, e.g. hyperactivity in children, intellectual deficits, in particular attention disturbances (attention deficit disorders), memory disturbances and cognitive disturbances, e.g. impaired learning and memory (impaired cognitive function), dementia, narcolepsy and sleep disturbances, e.g. restless legs syndrome; development disturbances; anxiety states, delirium; sexlife disturbances, e.g. impotence in men; eating disturbances, e.g. anorexia or bulimia; addiction; and other unspecified psychiatric disturbances.
The disorders which can be treated in accordance with the invention also include Parkinson's disease and epilepsy and, in particular, the affective disturbances connected thereto.
The addiction diseases include psychic disorders and behavioral disturbances which are caused by the abuse of psychotropic substances, such as pharmaceuticals or narcotics, and also other addiction diseases, such as addiction to gaming (impulse control disorders not elsewhere classified). Examples of addictive substances are: opioids (e.g. morphine, heroin and codeine), cocaine; nicotine; alcohol; substances which interact with the GABA chloride channel complex, sedatives, hypnotics and tranquilizers, for example benzodiazepines; LSD; cannabinoids; psychomotor stimulants, such as 3,4-methylenedioxy-N-methylamphetamine (ecstasy); amphetamine and amphetamine-like substances such as methylphenidate and other stimulants including caffeine. Addictive substances which come particularly into consideration are opioids, cocaine, amphetamine or amphetamine-like substances, nicotine and alcohol.
With regard to the treatment of addiction diseases, particular preference is given to those compounds according to the invention of the formula I which themselves do not possess any psychotropic effect. This can also be observed in a test using rats, which, after having been administered compounds which can be used in accordance with the invention, reduce their self administration of psychotropic substances, for example cocaine.
According to another aspect of the present invention, the compounds according to the invention are suitable for treating disorders whose causes can at least partially be attributed to an anomalous activity of dopamine D 3 receptors.
According to another aspect of the present invention, the treatment is directed, in particular, toward those disorders which can be influenced, within the sense of an expedient medicinal treatment, by the binding of preferably exogeneously administered binding partners (ligands) to dopamine D 3 receptors.
The diseases which can be treated with the compounds according to the invention are frequently characterized by progressive development, i.e. the above-described conditions change over the course of time; as a rule, the severity increases and conditions may possibly merge into each other or other conditions may appear in addition to those which already exist.
The compounds according to the invention can be used to treat a large number of signs, symptoms and/or malfunctions which are connected with the disorders of the central nervous system and, in particular, the abovementioned conditions. These signs, symptoms and/or malfunctions include, for example, a disturbed relationship to reality, lack of insight and ability to meet customary social norms or the demands made by life, changes in temperament, changes in individual drives, such as hunger, sleep, thirst, etc., and in mood, disturbances in the ability to observe and combine, changes in personality, in particular emotional lability, hallucinations, ego-disturbances, distractedness, ambivalence, autism, depersonalization and false perceptions, delusional ideas, chanting speech, lack of synkinesia, short-step gait, flexed posture of trunk and limbs, tremor, poverty of facial expression, monotonous speech, depressions, apathy, impeded spontaneity and decisiveness, impoverished association ability, anxiety, nervous agitation, stammering, social phobia, panic disturbances, withdrawal symptoms in association with dependency, maniform syndromes, states of excitation and confusion, dysphoria, dyskinetic syndromes and tic disorders, e.g. Huntington's chorea and Gilles-de-la-Tourette's syndrome, vertigo syndromes, e.g. peripheral positional, rotational and oscillatory vertigo, melancholia, hysteria, hypochondria and the like.
Within the meaning of the invention, a treatment also includes a preventive treatment (prophylaxis), in particular as relapse prophylaxis or phase prophylaxis, as well as the treatment of acute or chronic signs, symptoms and/or malfunctions. The treatment can be orientated symptomatically, for example as the suppression of symptoms. It can be effected over a short period, be orientated over the medium term or can be a long-term treatment, for example within the context of a maintenance therapy.
Therefore the compounds according to the invention are preferentially suitable for treating diseases of the central nervous system, in particular for treating affective disorders; neurotic disturbances, stress disturbances and somatoform disturbances and psychoses, and, in particular, for treating schizophrenia and depression. Because of their high selectivity with regard to the D 3 receptor, the compounds I according to the invention are also suitable for treating disturbances of kidney function, in particular disturbances of kidney function which are caused by diabetes mellitus (see WO 00/67847) and, especially, diabetic nephropathy.
Within the context of the treatment, the use according to the invention of the described compounds involves a method. In this method, an effective quantity of one or more compounds, as a rule formulated in accordance with pharmaceutical and veterinary practice, is administered to the individual to be treated, preferably a mammal, in particular a human being, productive animal or domestic animal. Whether such a treatment is indicated, and in which form it is to take place, depends on the individual case and is subject to medical assessment (diagnosis) which takes into consideration signs, symptoms and/or malfunctions which are present, the risks of developing particular signs, symptoms and/or malfunctions, and other factors.
As a rule, the treatment is effected by means of single or repeated daily administration, where appropriate together, or alternating, with other active compounds or active compound-containing preparations such that a daily dose of preferably from about 0.1 to 1000 mg/kg of bodyweight, in the case of oral administration, or of from about 0.1 to 100 mg/kg of bodyweight, in the case of parenteral administration, is supplied to an individual to be treated.
The invention also relates to the production of pharmaceutical compositions for treating an individual, preferably a mammal, in particular a human being, productive animal or domestic animal. Thus, the ligands are customarily administered in the form of pharmaceutical compositions which comprise a pharmaceutically acceptable excipient together with at least one compound according to the invention and, where appropriate, other active compounds. These compositions can, for example, be administered orally, rectally, transdermally, subcutaneously, intravenously, intramuscularly or intranasally.
Examples of suitable pharmaceutical formulations are solid medicinal forms, such as powders, granules, tablets, in particular film tablets, lozenges, sachets, cachets, sugar-coated tablets, capsules, such as hard gelatin capsules and soft gelatin capsules, suppositories or vaginal medicinal forms, semisolid medicinal forms, such as ointments, creams, hydrogels, pastes or plasters, and also liquid medicinal forms, such as solutions, emulsions, in particular oil-in-water emulsions, suspensions, for example lotions, injection preparations and infusion preparations, and eyedrops and eardrops. Implanted release devices can also be used for administering inhibitors according to the invention. In addition, it is also possible to use liposomes or microspheres.
When producing the compositions, the compounds according to the invention are optionally mixed or diluted with one or more excipients. Excipients can be solid, semisolid or liquid materials which serve as vehicles, carriers or medium for the active compound.
Suitable excipients are listed in the specialist medicinal monographs. In addition, the formulations can comprise pharmaceutically acceptable carriers or customary auxiliary substances, such as glidants; wetting agents; emulsifying and suspending agents; preservatives; antioxidants; antiirritants; chelating agents; coating auxiliaries; emulsion stabilizers; film formers; gel formers; odor masking agents; taste corrigents; resin; hydrocolloids; solvents; solubilizers; neutralizing agents; diffusion accelerators; pigments; quaternary ammonium compounds; refatting and overfatting agents; raw materials for ointments, creams or oils; silicone derivatives; spreading auxiliaries; stabilizers; sterilants; suppository bases; tablet auxiliaries, such as binders, fillers, glidants, disintegrants or coatings; propellants; drying agents; opacifiers; thickeners; waxes; plasticizers and white mineral oils. A formulation in this regard is based on specialist knowledge as described, for example, in Fiedler, H. P., Lexikon der Hilfsstoffe für Pharmazie, Kosmetik und angrenzende Gebiete [Encyclopedia of auxiliary substances for pharmacy, cosmetics and related fields], 4 th edition, Aulendorf: ECV-Editio-Kantor-Verlag, 1996.
The following examples serve to explain the invention without limiting it.
The compounds were either characterized via proton-NMR in d 4 -methanol, d 6 -dimethylsulfoxid or d-chloroform on a 400 MHz or 500 MHz NMR instrument (Bruker AVANCE), or by mass spectrometry, generally recorded via HPLC-MS in a fast gradient on C18-material (electrospray-ionisation (ESI) mode), or melting point.
The magnetic nuclear resonance spectral properties (NMR) refer to the chemical shifts (6) expressed in parts per million (ppm). The relative area of the shifts in the 1 H NMR spectrum corresponds to the number of hydrogen atoms for a particular functional type in the molecule. The nature of the shift, as regards multiplicity, is indicated as singlet (s), broad singlet (s. br.), doublet (d), broad doublet (d br.), triplet (t), broad triplet (t br.), quartet (q), quintet (quint.) and multiplet (m).

III. Examples of Galenic Administration Forms
A) Tablets
Tablets of the following composition are pressed on a tablet press in the customary manner:
40 mg of substance from Example 8
120 mg of corn starch
13.5 mg of gelatin
45 mg of lactose
2.25 mg of Aerosil® (chemically pure silicic acid in submicroscopically fine dispersion)
6.75 mg of potato starch (as a 6% paste)
B) Sugar-Coated Tablets
20 mg of substance from Example 8
60 mg of core composition 70 mg of saccharification composition
The core composition consists of 9 parts of corn starch, 3 parts of lactose and 1 part of 60:40 vinylpyrrolidone/vinyl acetate copolymer. The saccharification composition consists of 5 parts of cane sugar, 2 parts of corn starch, 2 parts of calcium carbonate and 1 part of talc. The sugar-coated tablets which had been prepared in this way are subsequently provided with a gastric juice-resistant coating.
IV. Biological Investigations
Receptor Binding Studies:
The substance to be tested was either dissolved in methanol/Chremophor® (BASF-AG) or in dimethyl sulfoxide and then diluted with water to the desired concentration.
Dopamine D 3 Receptor:
The assay mixture (0.250 ml) was composed of membranes derived from ˜10 6 HEK-293 cells possessing stably expressed human dopamine D 3 receptors, 0.1 nM [ 125 I]-iodosulpride and incubation buffer (total binding) or, in addition, test substance (inhibition curve) or 1 μM spiperone (nonspecific binding). Each assay mixture was run in triplicate.
The incubation buffer contained 50 mM tris, 120 mM NaCl, 5 mM KCl, 2 mM CaCl 2 , 2 mM MgCl 2 and 0.1% bovine serum albumin, 10 μM quinolone and 0.1% ascorbic acid (prepared fresh daily). The buffer was adjusted to pH 7.4 with HCl.
Dopamine D 2L Receptor:
The assay mixture (1 ml) was composed of membranes from ˜106 HEK-293 cells possessing stably expressed human dopamine D 2L receptors (long isoform) and 0.01 nM [ 125 I]iodospiperone and incubation buffer (total binding) or, in addition, test substance (inhibition curve) or 1 μM haloperidol (nonspecific binding). Each assay mixture was run in triplicate.
The incubation buffer contained 50 mM tris, 120 mM NaCl, 5 mM KCl, 2 mM CaCl 2 , 2 mM MgCl 2 and 0.1% bovine serum albumin. The buffer was adjusted to pH 7.4 with HCl.
Measurement and Analysis:
After having been incubated at 25° C. for 60 minutes, the assay mixtures were filtered through a Whatman GF/B glass fiber filter under vacuum using a cell collecting device. The filters were transferred to scintillation viols using a filter transfer system. After 4 ml of Ultima Gold® (Packard) have been added, the samples were shaken for one hour and the radioactivity was then counted in a Beta-Counter (Packard, Tricarb 2000 or 2200CA). The cpm values were converted into dpm using a standard quench series and the program belonging to the instrument.
The inhibition curves were analyzed by means of iterative nonlinear regression analysis using the Statistical Analysis System (SAS) which is similar to the “LIGAND” program described by Munson and Rodbard.
The results of the receptor binding studies are expressed as receptor binding constants K i (D 2 ) and K i (D 3 ), respectively, as herein before described, and given in table 1.
In these tests, the compounds according to the invention exhibit very good affinities for the D 3 receptor (<10 nM, frequently <5 nM) and bind selectively to the D 3 receptor.
The results of the binding tests are given in table 1.
