7.Description:
(en)[0001] This application is a continuation-in-part of copending U.S. provisional application Ser. No. 60/163,920, filed Nov. 5, 1999.
TECHNICAL FIELD
[0002] This invention relates to quinoline and naphthyridine carboxylic acid derivatives having antibacterial properties, processes for making of the compounds, methods of treatment using the compounds and pharmaceutical compositions containing the compounds. Specifically, it relates to quinoline and naphthyridine carboxylic acid derivatives having a carbon-carbon linkage at the C-7 position of the molecule.
BACKGROUND OF THE INVENTION
[0003] Many compounds having the quinoline carboxylic acid nucleus are known in the art for their antibacterial activity in curing infectious diseases. Some of the known antibiotics on the market to-date include, for example, ciprofloxacin (U.S. Pat. No. 4,670,444), norfloxacin (U.S. Pat. No. 4,146,719), enoxacin (U.S. Pat. No. 4,352,803), and tosufloxacin (U.S. Pat. No. 4,704,459). Most of these known quinoline carboxylic acid antibacterial compounds have a carbon-nitrogen linkage at the C-7 position of the quinoline nucleus.
[0004] There is a continuing need for discovering compounds which are more effective against resistant bacteria, have improved intestinal absorption, metabolic stability, and exhibit less phototoxicity and cytotoxicity.

[0315] Asymmetric centers can exist in the compounds of the invention. The compounds described herein may be stereoisomers or mixtures thereof. Individual stereoisomers of compounds are prepared by synthesis from starting materials containing the chiral centers or by preparation of mixtures of enantiomeric products followed by separation such as conversion to a mixture of diastereomers followed by separation or recrystallization, chromatographic techniques, or direct separation of the enantiomers on chiral chromatographic columns. Starting compounds of particular stereochemistry are either commercially available or are made by the methods described herein and resolved by techniques well-known in the art. It should be understood that the invention encompasses any stereoisomeric, diastereomeric, or enantiomeric form of the compounds of this invention, or mixtures thereof, which possess antibacterial activity, and is not limited to any one stereoisomer or stereoisomeric mixture.
[0316] According to the methods of treatment of the invention, the compounds can be administered alone, in combination with, or in concurrent therapy with other antibacterial agents. When using the compounds for antibacterial therapy, the specific therapeutically effective dose level for any particular patient will depend upon factors such as the disorder being treated and the severity of the disorder; the activity of the particular compound used; the specific composition employed; the age, body weight, general health, sex, and diet of the patient; the time of administration; the route of administration; the rate of excretion of the compound employed; the duration of treatment; and drugs used in combination with or coincidently with the compound used. The compounds can be administered orally, parenterally, osmotically (nasal sprays), rectally, vaginally, or topically in unit dosage formulations containing carriers, adjuvants, diluents, vehicles, or combinations thereof. The term “parenteral” includes infusion as well as subcutaneous, intravenous, intramuscular, and intrasternal injection.
[0317] Parenterally adminstered aqueous or oleaginous suspensions of the compounds can be formulated with dispersing, wetting, or suspending agents. The injectable preparation can also be an injectable solution or suspension in a diluent or solvent. Among the acceptable diluents or solvents employed are water, saline, Ringer's solution, buffers, dilute acids or bases, dilute amino acid solutions, monoglycerides, diglycerides, fatty acids such as oleic acid, and fixed oils such as monoglycerides or diglycerides.
[0318] The antibacterial effect of parenterally administered compounds can be prolonged by slowing their absorption. One way to slow the absorption of a particular compound is adminstering injectable depot forms comprising suspensions of crystalline, amorphous, or otherwise water-insoluble forms of the compound. The rate of absorption of the compound is dependent on its rate of dissolution which is, in turn, dependent on its physical state. Another way to slow absorption of a particular compound is administering injectable depot forms comprising the compound as an oleaginous solution or suspension. Yet another way to slow absorption of a particular compound is administering injectable depot forms comprising microcapsule matrices of the compound trapped within liposomes, microemulsions, or biodegradable polymers such as polylactide-polyglycolide, polyorthoesters or polyanhydrides. Depending on the ratio of drug to polymer and the composition of the polymer, the rate of drug release can be controlled.
[0319] Transdermal patches also provide controlled delivery of the compounds. The rate of absorption can be slowed by using rate controlling membranes or by trapping the compound within a polymer matrix or gel. Conversely, absorption enhancers can be used to increase absorption.
[0320] Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In these solid dosage forms, the active compound can optionally comprise diluents such as sucrose, lactose, starch, talc, silicic acid, aluminum hydroxide, calcium silicates, polyamide powder, tableting lubricants, and tableting aids such as magnesium stearate or microcrystalline cellulose. Capsules, tablets and pills can also comprise buffering agents; and tablets and pills can be prepared with enteric coatings or other release-controlling coatings. Powders and sprays can also contain excipients such as talc, silicic acid, aluminum hydroxide, calcium silicate, polyamide powder, or mixtures thereof. Sprays can additionally contain customary propellants such as chlorofluorohydrocarbons or substitutes therefor.
[0321] Liquid dosage forms for oral administration include emulsions, microemulsions, solutions, suspensions, syrups, and elixirs comprising inert diluents such as water. These compositions can also comprise adjuvants such as wetting, emulsifying, suspending, sweetening, flavoring, and perfuming agents.
[0322] Topical dosage forms include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants, and transdermal patches. The compound is mixed under sterile conditions with a carrier and any needed preservatives or buffers. These dosage forms can also include excipients such as animal and vegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, talc and zinc oxide, or mixtures thereof. Suppositories for rectal or vaginal administration can be prepared by mixing the compounds with a suitable nonirritating excipient such as cocoa butter or polyethylene glycol, each of which is solid at ordinary temperature but fluid in the rectum or vagina. Ophthalmic formulations comprising eye drops, eye ointments, powders, and solutions are also contemplated as being within the scope of this invention.
[0323] A further possibility for delivery and utilization of the compounds is chemical conjugation of the compounds with other antibacterials. Similar dual-action conjugates are reported in U.S. Pat. No. 5,281,703. In the manner suggested by these references, a covalent bond can be formed between a functional group on a lactam and an amino group at the C-6 position or a carboxylic acid group at the C-3 position of the quinoline or naphthyridine.
[0324] The total daily dose of the compounds administered to a host in single or divided doses can be in amounts from about 0.1 to about 200 mg/kg body weight or preferably from about 0.25 to about 100 mg/kg body weight. Single dose compositions can contain these amounts or submultiples thereof to make up the daily dose.

[0731] Assay A. Determination of Biological Activity In Vitro Assay of Antibacterial Activity
[0732] Representative compounds of the invention were assayed in vitro for antibacterial activity. Twelve petri dishes containing successive aqueous dilutions of the test compound mixed with sterilized Brain Heart Infusion (BHI) agar (Difco 0418-01-5) (10 mL) were prepared. Each plate was inoculated with 1:100 (or 1:10 for slow-growing strains, such as Micrococcus and Streptococcus) dilutions of up to 32 different microorganisms using a Steers replicator block. The inoculated plates were incubated at 35-37° C. for about 20 to about 24 hours. In addition, a control plate with BHI agar and no test compound was prepared and incubated at the beginning and end of each test.
[0733] An additional plate containing a compound having known susceptibility patterns for the organisms being tested and belonging to the same antibiotic class as the test compound was also prepared and incubated as a further control and to provide test-to-test comparability. Ciprofloxacin was used for this purpose.
[0734] After incubation, each plate was visually inspected. The minimum inhibitory concentration (MIC) was defined as the lowest concentration of drug yielding no growth, a slight haze, or sparsely isolated colonies on the inoculum spot as compared to the growth control. The results of this assay, shown in Table 1, demonstrate the antibacterial activity of the compounds of the invention.

[0736] Assay B. Determination of Biological Activity In Vitro Assay of Antibacterial Activity
[0737] Representative compounds of the invention were assayed in vitro for antibacterial activity. The susceptibilities of aerobic, nonfastidious species were determined visually by broth microdilution as described by the National Committee for Clinical Laboratory Standards (NCCLS) (National Committee for Clinical Laboratory Standards. 1997. Methods for dilution antimicrobial susceptibility tests for bacteria that grow aerobically. Approved standard M7-A4. National Committee for Clinical Laboratory Standards. Wayne, Pa.). In brief, serial two-fold dilutions of test compounds were made in cation-adjusted Mueller Hinton broth at two-times the final concentration. Inocula were prepared from overnight cultures of test strains. Tests were inoculated with a suspension of bacteria in Mueller Hinton broth to achieve a final density of approximately 5×10 5 CFU/mL. Tests were incubated at 35° C. in ambient air for 16 to 20 hr. Minimum Inhibitory Concentrations (MICs) were determined as the lowest drug concentration completely inhibiting growth. Ciprofloxacin was included as a control. For testing S. pneumoniae , the cation-adjusted Mueller Hinton broth was supplemented with 3% lysed horse blood and the incubation period was extended to 20 to 24 hr. For testing H. influenzae , the cation-adjusted Mueller Hinton broth was supplemented with 5 g/L yeast extract, 0.3 mmol/L hematin and 15 mg/L NAD and incubation was extended to 20 to 24 hr.. The results of this assay, shown in Table 2, demonstrate the antibacterial activity of the compounds of the invention.

[0741] Synthetic Methods
[0742] The compounds and processes of the invention will be better understood in connection with the following synthetic schemes which illustrate methods by which the compounds can be prepared. The compounds can be prepared by a variety of synthetic routes. Representative procedures are shown in Schemes 1-6. It will be readily apparent that the compounds can be synthesized by substitution of the appropriate reactants and agents in the syntheses shown below. It will also be apparent that the selective protection and deprotection steps, as well as the order of the steps themselves, can be carried out in varying order, depending on the nature of the reactions. A thorough discussion of protecting groups is provided in Greene and Wuts, “Protective Groups in Organic Synthesis,” 2nd Ed., John Wiley & Son, Inc., 1991.
[0743] Precursor compounds, intermediates, and reagents are commercially available or can be prepared from commercially available starting materials. Functional group transformations useful for preparing compounds of the invention are reported in Larock, “Comprehensive Organic Transformations. A Guide to Functional Group Preparations,” VCH Publishers, New York (1989). The groups A 1 , A 2 , Q 1 , Q 2 , R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 , R 9 , R 10 , R 12 , R 13 , R 14 , R 15 , R 16 , W, and Z are as defined above unless otherwise noted below. In the following schemes, the group R 11a is a carboxyl protecting group.
[0744] A synthesis of compounds of formula (Ic) is shown in Scheme 1. Conversion of compounds of formula (i), wherein X 1 is halide, to compounds of formula (Ic) can be achieved by means such as those reported in U.S. Pat. No. 5,282,703. The starting materials are available commercially or can be prepared by well-known means. For example, commercially available 4-bromo-2-fluorobenzoic acid (Alfa/Aesar, Ward Hill, Mass.), ethyl 3-hydroxybenzoate, and 2,6-dichloronicotinic acid (Aldrich Chemical Company, Milwaukee, Wis.) ultimately provide compounds of formula (Ic). A list of additional starting materials (i) with references for their preparation is as follows:

[0752] An alternative method of preparing compounds of formula (Ic) is disclosed in U.S. Pat. No. 6,025,370, which can be employed to prepare derivatives, such as, for example, ethyl 7-bromo-1-cyclopropyl-8-methyl-4-oxo-1,4-dihydroquinoline-3-carboxylate.
[0753] As shown in Scheme 2, compounds of formula (Id) can be nitrated with fuming nitric acid in sulfuric acid to provide compounds of formula (ii). Conversion of compounds of formula (ii) to compounds of formula (Ie) can be achieved with metal powder such as zinc, iron, or tin in acids such as hydrochloric, hydrobromic, sulfuric, acetic, trifluoroacetic, or mixtures thereof. Additional compounds of formula (Ie) can be prepared by alkylating the amino group at the C-6 position of the compounds of formula (Ie) with alkyl chlorides, bromides, or iodides in the presence of a base such as cesium carbonate, potassium bicarbonate, sodium hydride, or potassium hydride.
[0754] A synthesis of compounds of formula (If) wherein R 2 and R 3 are taken together is shown in Scheme 3. Conversion of ehtyl 3-aminobenzoate to ethyl 3-amino-2,4-dibromobenzoate can be achieved by means well-known in the art. The ethyl 3-amino-2,4-dibromobenzoate can then be converted to ethyl 2,4-dibromo-3-chlorobenzoate by diazotization/chlorination according to the procecure described in Chem. Pharm. Bull. 37(8) 2103 (1989) or alternatively converted ethyl 3-amino-2,4-dibromobenzoate by diazotization/reduction as described in J. Am. Chem. Soc. 72, 3013 (1950) and J. Org. Chem. 42, 1469 (1977). Each of these substituted benzoic acids can then be elaborated to compounds of formulas (v), (vi), and (Ic) as described in Scheme 1 and in U.S. Pat. Nos. 4,382,892 and 4,762,831.
[0755] The functionalized amines of formula (iv) can be optionally protected amino acids, amino sulfhydryls, or amino alcohols, the latter two of which can be derived from amino acids of known stereochemistry by preparations such as those described in Tetrahedron Lett. 36(8) 1223 (1995).
[0756] As shown in Scheme 4, compounds of formula (Ic) in which Q 1 is a first covalent bond precursor, for example, bromine, can be prepared from compounds of formula (Ig), which possesses a suitable leaving group at the quinolone C-7 position.
[0757] Compounds of formula (Ig) can be converted to compounds of formula (vii) by treatment of the former with an azido compound, for example sodium azide. Solvents useful for the reaction include polar aprotic solvents such as DMF, NMP, THF, and the like. The temperatures at which the reactions are conducted typically range from about 25° C. to about 100° C.
[0758] Conversion of compounds of formula (vii) to compounds of formula (viii) can be achieved by treatment of the former with hydrogen gas and a hydrogenation catalyst. Representative catalysts include palladium on carbon and palladium on alumina. Solvents useful for the reaction include methanol, ethanol, THF, 1,4-dioxane, and the like. The reaction is generally carried out at ambient temperature.
[0759] Conversion of compounds of formula (viii) to compounds of formula (Ic) can be achieved by diazotization in the presence of a copper salt. Representative copper salts include cuprous or cupric salts, including copper(II) bromide and copper(I) chloride. Solvents useful for the reaction include aqueous acids, for example dilute aqueous hydrobromic acid. The reaction is generally carried out at about 0° C.
[0760] Scheme 5 is an alternative method for preparation of compounds with C-5 and C-6 substituents. Compounds of formula (ix) can undergo nucleophilic aromatic substitution at position C-5 by treatment with a protected amine to give compounds of formula (x), wherein R P is an amino protecting group. Examples of protected amines include 2,4-dimethoxybenzylamine, benzylamine, and the like. Solvents useful for the reaction include trichloroethylene, which can be employed in a temperature range of from about 80° C. to about 85° C.
[0761] Deprotection of compounds of formula (x) to give compounds of formula (Ih) can be achieved by several standard means well known in the art. For example, treatment of a benzyl or substituted benzyl derivative under hydrogenation conditions or TFA give the desired aniline product.
[0762] Conversion of compounds of formula (Ih) to compounds of formula (Ii) can be achieved by treatment of the former with electrophilic reagents via electrophilic aromatic substitution. Representative electrophilic agents include 1,3-dichloro-5,5-dimethylhydantoin, sulfuryl chloride, N-bromosuccinimide, and the like. Solvents useful for the reaction include halogenated solvents including dichloromethane, chloroform, and the like.
[0763] 4-Bromo-2,6-difluorobenzoic acid (xi) (prepared by the method of Mongin, F; Schlosser, M. Tetrahedron Lett. 1996, 37, 6551) can be converted to its oxazole derivative (xii) under standard conditions, lithiated with an appropriate base such as lithium tetramethylpiperidide or the like, and alkylated with a suitable alkylating agent such as iodomethane, dimethyl sulfate, and the like to give (xiii). The resulting product can then be hydrolyzed under acidic conditions to provide the compound of formula (i-a). This acid can easily be converted to compound (ix-a) according to Scheme 1 and further converted to compound (Ik) according to Scheme 5.
[0764] As shown in Scheme 7, compounds of formula (xiv), which are commercially available or prepared by means well-known in the art, can be converted to compounds of formula (Ib) by treatment with a base such as the lithium bis(trimethylsilyl)amide, sodium bis(trimethylsilyl)amide, potassium bis(trimethylsilyl)amide, n-butyllithium, sec-butyllithium, tert-butyllithium, and lithium diisopropylamide followed by treatment of the resulting anion with a Q 2 precursor such as bromine, N-bromosuccinimide, a trialkoxyborane, and a trialkylstannyl halide. For compounds of formula (Ib) wherein Q 2 is halide, the halide can be further derivatized by treatment with a metal such as magnesium or zinc to provide the corresponding magnesium halide or zinc halide. For compounds of formula (Ib), wherein Q 2 is a boronic ester, the boronic ester can be hydrolyzed to the boronic acid with a base such as lithium hydroxide, sodium hydroxide, and potassium hydroxide or an acid such as hydrochloric or hydrobromic.
[0765] As shown in Scheme 8, compounds of formula (I) can be prepared from precursor compounds of formulas (Ia) and (Ib) in the presence of a catalyst. Examples of catalysts include tetrakis(triphenylphosphine)palladium(O), palladium(II) chloride(dibenzylidine acetone), and palladium(II) chloride bis(triphenylphosphine). If necessary, these reactions can be run on the presence of base such as Na 2 CO 3 , Cs 2 CO 3 , CsF, and K 2 HPO 4 , additives such as LiCl, or ligands such as triphenylphosphine, triphenylarsine, and trialkylphosphines such as tributylphosphine.
[0766] As shown in Scheme 9, the ester group of compounds of formula (I) can be directly converted to aldehydes by treatment of the former with a hydride donating agents such as diisobutylaluminum hydride. An alternative conversion of ester groups of compounds of formula (I) to aldehydes is conversion of the corresponding acid to a Weinreb amide, exemplified by compounds of formula (xv) wherein R 16 is —N(CH 3 )(OCH 3 ), followed by treatment with the aformentioned hydride donating agents.
[0767] Yet another alternative conversion of the ester group of compounds of formula (I) to aldehydes is conversion of the corresponding acid to a thioester followed by treatment of the thioester with a hydrogen source and a catalyst. Examples of hydrogen sources are hydrogen gas or triethylsilane. Examples of catalysts are palladium on carbon or platinum on carbon.

TECHNICAL FIELD
[0002] This invention relates to quinoline and naphthyridine carboxylic acid derivatives having antibacterial properties, processes for making of the compounds, methods of treatment using the compounds and pharmaceutical compositions containing the compounds. Specifically, it relates to quinoline and naphthyridine carboxylic acid derivatives having a carbon-carbon linkage at the C-7 position of the molecule.
BACKGROUND OF THE INVENTION
[0003] Many compounds having the quinoline carboxylic acid nucleus are known in the art for their antibacterial activity in curing infectious diseases. Some of the known antibiotics on the market to-date include, for example, ciprofloxacin (U.S. Pat. No. 4,670,444), norfloxacin (U.S. Pat. No. 4,146,719), enoxacin (U.S. Pat. No. 4,352,803), and tosufloxacin (U.S. Pat. No. 4,704,459). Most of these known quinoline carboxylic acid antibacterial compounds have a carbon-nitrogen linkage at the C-7 position of the quinoline nucleus.

The injectable preparation can also be an injectable solution or suspension in a diluent or solvent. Among the acceptable diluents or solvents employed are water, saline, Ringer's solution, buffers, dilute acids or bases, dilute amino acid solutions, monoglycerides, diglycerides, fatty acids such as oleic acid, and fixed oils such as monoglycerides or diglycerides.
[0318] The antibacterial effect of parenterally administered compounds can be prolonged by slowing their absorption. One way to slow the absorption of a particular compound is adminstering injectable depot forms comprising suspensions of crystalline, amorphous, or otherwise water-insoluble forms of the compound. The rate of absorption of the compound is dependent on its rate of dissolution which is, in turn, dependent on its physical state. Another way to slow absorption of a particular compound is administering injectable depot forms comprising the compound as an oleaginous solution or suspension. Yet another way to slow absorption of a particular compound is administering injectable depot forms comprising microcapsule matrices of the compound trapped within liposomes, microemulsions, or biodegradable polymers such as polylactide-polyglycolide, polyorthoesters or polyanhydrides. Depending on the ratio of drug to polymer and the composition of the polymer, the rate of drug release can be controlled.
[0319] Transdermal patches also provide controlled delivery of the compounds. The rate of absorption can be slowed by using rate controlling membranes or by trapping the compound within a polymer matrix or gel. Conversely, absorption enhancers can be used to increase absorption.
[0320] Solid dosage forms for oral administration include capsules, tablets, pills, powders, and granules. In these solid dosage forms, the active compound can optionally comprise diluents such as sucrose, lactose, starch, talc, silicic acid, aluminum hydroxide, calcium silicates, polyamide powder, tableting lubricants, and tableting aids such as magnesium stearate or microcrystalline cellulose. Capsules, tablets and pills can also comprise buffering agents; and tablets and pills can be prepared with enteric coatings or other release-controlling coatings. Powders and sprays can also contain excipients such as talc, silicic acid, aluminum hydroxide, calcium silicate, polyamide powder, or mixtures thereof. Sprays can additionally contain customary propellants such as chlorofluorohydrocarbons or substitutes therefor.
[0321] Liquid dosage forms for oral administration include emulsions, microemulsions, solutions, suspensions, syrups, and elixirs comprising inert diluents such as water. These compositions can also comprise adjuvants such as wetting, emulsifying, suspending, sweetening, flavoring, and perfuming agents.
[0322] Topical dosage forms include ointments, pastes, creams, lotions, gels, powders, solutions, sprays, inhalants, and transdermal patches. The compound is mixed under sterile conditions with a carrier and any needed preservatives or buffers. These dosage forms can also include excipients such as animal and vegetable fats, oils, waxes, paraffins, starch, tragacanth, cellulose derivatives, polyethylene glycols, silicones, bentonites, silicic acid, talc and zinc oxide, or mixtures thereof. Suppositories for rectal or vaginal administration can be prepared by mixing the compounds with a suitable nonirritating excipient such as cocoa butter or polyethylene glycol, each of which is solid at ordinary temperature but fluid in the rectum or vagina. Ophthalmic formulations comprising eye drops, eye ointments, powders, and solutions are also contemplated as being within the scope of this invention.
[0323] A further possibility for delivery and utilization of the compounds is chemical conjugation of the compounds with other antibacterials. Similar dual-action conjugates are reported in U.S. Pat. No. 5,281,703. In the manner suggested by these references, a covalent bond can be formed between a functional group on a lactam and an amino group at the C-6 position or a carboxylic acid group at the C-3 position of the quinoline or naphthyridine.
[0324] The total daily dose of the compounds administered to a host in single or divided doses can be in amounts from about 0.1 to about 200 mg/kg body weight or preferably from about 0.25 to about 100 mg/kg body weight. Single dose compositions can contain these amounts or submultiples thereof to make up the daily dose.

[0731] Assay A. Determination of Biological Activity In Vitro Assay of Antibacterial Activity
[0732] Representative compounds of the invention were assayed in vitro for antibacterial activity. Twelve petri dishes containing successive aqueous dilutions of the test compound mixed with sterilized Brain Heart Infusion (BHI) agar (Difco 0418-01-5) (10 mL) were prepared. Each plate was inoculated with 1:100 (or 1:10 for slow-growing strains, such as Micrococcus and Streptococcus) dilutions of up to 32 different microorganisms using a Steers replicator block. The inoculated plates were incubated at 35-37° C. for about 20 to about 24 hours. In addition, a control plate with BHI agar and no test compound was prepared and incubated at the beginning and end of each test.
[0733] An additional plate containing a compound having known susceptibility patterns for the organisms being tested and belonging to the same antibiotic class as the test compound was also prepared and incubated as a further control and to provide test-to-test comparability. Ciprofloxacin was used for this purpose.
[0734] After incubation, each plate was visually inspected. The minimum inhibitory concentration (MIC) was defined as the lowest concentration of drug yielding no growth, a slight haze, or sparsely isolated colonies on the inoculum spot as compared to the growth control. The results of this assay, shown in Table 1, demonstrate the antibacterial activity of the compounds of the invention.

[0736] Assay B. Determination of Biological Activity In Vitro Assay of Antibacterial Activity
[0737] Representative compounds of the invention were assayed in vitro for antibacterial activity. The susceptibilities of aerobic, nonfastidious species were determined visually by broth microdilution as described by the National Committee for Clinical Laboratory Standards (NCCLS) (National Committee for Clinical Laboratory Standards. 1997. Methods for dilution antimicrobial susceptibility tests for bacteria that grow aerobically. Approved standard M7-A4. National Committee for Clinical Laboratory Standards. Wayne, Pa.). In brief, serial two-fold dilutions of test compounds were made in cation-adjusted Mueller Hinton broth at two-times the final concentration. Inocula were prepared from overnight cultures of test strains. Tests were inoculated with a suspension of bacteria in Mueller Hinton broth to achieve a final density of approximately 5×10 5 CFU/mL. Tests were incubated at 35° C. in ambient air for 16 to 20 hr. Minimum Inhibitory Concentrations (MICs) were determined as the lowest drug concentration completely inhibiting growth. Ciprofloxacin was included as a control. For testing S. pneumoniae , the cation-adjusted Mueller Hinton broth was supplemented with 3% lysed horse blood and the incubation period was extended to 20 to 24 hr. For testing H. influenzae , the cation-adjusted Mueller Hinton broth was supplemented with 5 g/L yeast extract, 0.3 mmol/L hematin and 15 mg/L NAD and incubation was extended to 20 to 24 hr..

For example, commercially available 4-bromo-2-fluorobenzoic acid (Alfa/Aesar, Ward Hill, Mass.), ethyl 3-hydroxybenzoate, and 2,6-dichloronicotinic acid (Aldrich Chemical Company, Milwaukee, Wis.) ultimately provide compounds of formula (Ic). A list of additional starting materials (i) with references for their preparation is as follows:

[0753] As shown in Scheme 2, compounds of formula (Id) can be nitrated with fuming nitric acid in sulfuric acid to provide compounds of formula (ii). Conversion of compounds of formula (ii) to compounds of formula (Ie) can be achieved with metal powder such as zinc, iron, or tin in acids such as hydrochloric, hydrobromic, sulfuric, acetic, trifluoroacetic, or mixtures thereof. Additional compounds of formula (Ie) can be prepared by alkylating the amino group at the C-6 position of the compounds of formula (Ie) with alkyl chlorides, bromides, or iodides in the presence of a base such as cesium carbonate, potassium bicarbonate, sodium hydride, or potassium hydride.
[0754] A synthesis of compounds of formula (If) wherein R 2 and R 3 are taken together is shown in Scheme 3. Conversion of ehtyl 3-aminobenzoate to ethyl 3-amino-2,4-dibromobenzoate can be achieved by means well-known in the art. The ethyl 3-amino-2,4-dibromobenzoate can then be converted to ethyl 2,4-dibromo-3-chlorobenzoate by diazotization/chlorination according to the procecure described in Chem. Pharm. Bull. 37(8) 2103 (1989) or alternatively converted ethyl 3-amino-2,4-dibromobenzoate by diazotization/reduction as described in J. Am. Chem. Soc. 72, 3013 (1950) and J. Org. Chem. 42, 1469 (1977). Each of these substituted benzoic acids can then be elaborated to compounds of formulas (v), (vi), and (Ic) as described in Scheme 1 and in U.S. Pat. Nos. 4,382,892 and 4,762,831.
[0755] The functionalized amines of formula (iv) can be optionally protected amino acids, amino sulfhydryls, or amino alcohols, the latter two of which can be derived from amino acids of known stereochemistry by preparations such as those described in Tetrahedron Lett. 36(8) 1223 (1995).
[0756] As shown in Scheme 4, compounds of formula (Ic) in which Q 1 is a first covalent bond precursor, for example, bromine, can be prepared from compounds of formula (Ig), which possesses a suitable leaving group at the quinolone C-7 position.
[0757] Compounds of formula (Ig) can be converted to compounds of formula (vii) by treatment of the former with an azido compound, for example sodium azide. Solvents useful for the reaction include polar aprotic solvents such as DMF, NMP, THF, and the like. The temperatures at which the reactions are conducted typically range from about 25° C. to about 100° C.
[0758] Conversion of compounds of formula (vii) to compounds of formula (viii) can be achieved by treatment of the former with hydrogen gas and a hydrogenation catalyst. Representative catalysts include palladium on carbon and palladium on alumina. Solvents useful for the reaction include methanol, ethanol, THF, 1,4-dioxane, and the like. The reaction is generally carried out at ambient temperature.
[0759] Conversion of compounds of formula (viii) to compounds of formula (Ic) can be achieved by diazotization in the presence of a copper salt. Representative copper salts include cuprous or cupric salts, including copper(II) bromide and copper(I) chloride. Solvents useful for the reaction include aqueous acids, for example dilute aqueous hydrobromic acid. The reaction is generally carried out at about 0° C.
[0760] Scheme 5 is an alternative method for preparation of compounds with C-5 and C-6 substituents. Compounds of formula (ix) can undergo nucleophilic aromatic substitution at position C-5 by treatment with a protected amine to give compounds of formula (x), wherein R P is an amino protecting group. Examples of protected amines include 2,4-dimethoxybenzylamine, benzylamine, and the like. Solvents useful for the reaction include trichloroethylene, which can be employed in a temperature range of from about 80° C. to about 85° C.
[0761] Deprotection of compounds of formula (x) to give compounds of formula (Ih) can be achieved by several standard means well known in the art. For example, treatment of a benzyl or substituted benzyl derivative under hydrogenation conditions or TFA give the desired aniline product.
[0762] Conversion of compounds of formula (Ih) to compounds of formula (Ii) can be achieved by treatment of the former with electrophilic reagents via electrophilic aromatic substitution. Representative electrophilic agents include 1,3-dichloro-5,5-dimethylhydantoin, sulfuryl chloride, N-bromosuccinimide, and the like. Solvents useful for the reaction include halogenated solvents including dichloromethane, chloroform, and the like.
[0763] 4-Bromo-2,6-difluorobenzoic acid (xi) (prepared by the method of Mongin, F; Schlosser, M. Tetrahedron Lett. 1996, 37, 6551) can be converted to its oxazole derivative (xii) under standard conditions, lithiated with an appropriate base such as lithium tetramethylpiperidide or the like, and alkylated with a suitable alkylating agent such as iodomethane, dimethyl sulfate, and the like to give (xiii). The resulting product can then be hydrolyzed under acidic conditions to provide the compound of formula (i-a). This acid can easily be converted to compound (ix-a) according to Scheme 1 and further converted to compound (Ik) according to Scheme 5.
[0764] As shown in Scheme 7, compounds of formula (xiv), which are commercially available or prepared by means well-known in the art, can be converted to compounds of formula (Ib) by treatment with a base such as the lithium bis(trimethylsilyl)amide, sodium bis(trimethylsilyl)amide, potassium bis(trimethylsilyl)amide, n-butyllithium, sec-butyllithium, tert-butyllithium, and lithium diisopropylamide followed by treatment of the resulting anion with a Q 2 precursor such as bromine, N-bromosuccinimide, a trialkoxyborane, and a trialkylstannyl halide. For compounds of formula (Ib) wherein Q 2 is halide, the halide can be further derivatized by treatment with a metal such as magnesium or zinc to provide the corresponding magnesium halide or zinc halide. For compounds of formula (Ib), wherein Q 2 is a boronic ester, the boronic ester can be hydrolyzed to the boronic acid with a base such as lithium hydroxide, sodium hydroxide, and potassium hydroxide or an acid such as hydrochloric or hydrobromic.
[0765] As shown in Scheme 8, compounds of formula (I) can be prepared from precursor compounds of formulas (Ia) and (Ib) in the presence of a catalyst. Examples of catalysts include tetrakis(triphenylphosphine)palladium(O), palladium(II) chloride(dibenzylidine acetone), and palladium(II) chloride bis(triphenylphosphine). If necessary, these reactions can be run on the presence of base such as Na 2 CO 3 , Cs 2 CO 3 , CsF, and K 2 HPO 4 , additives such as LiCl, or ligands such as triphenylphosphine, triphenylarsine, and trialkylphosphines such as tributylphosphine.
[0766] As shown in Scheme 9, the ester group of compounds of formula (I) can be directly converted to aldehydes by treatment of the former with a hydride donating agents such as diisobutylaluminum hydride. An alternative conversion of ester groups of compounds of formula (I) to aldehydes is conversion of the corresponding acid to a Weinreb amide, exemplified by compounds of formula (xv) wherein R 16 is —N(CH 3 )(OCH 3 ), followed by treatment with the aformentioned hydride donating agents.
[0767] Yet another alternative conversion of the ester group of compounds of formula (I) to aldehydes is conversion of the corresponding acid to a thioester followed by treatment of the thioester with a hydrogen source and a catalyst. Examples of hydrogen sources are hydrogen gas or triethylsilane. Examples of catalysts are palladium on carbon or platinum on carbon.

One tube was charged with 1 ml 1:1/dichloromethane:dimethylacetamide, N-cyclohexylcarbodiimide, N′-methyl polystyrene HL (NovaBiochem, 200-400 mesh, 2% DVB, 1.52 mmol/g loading) (0.151 g, 0.23 mmol), 1-hydroxybenzotriazole hydrate (0.003 g, 0.019 mmol) and N-(9-fluorenylmethoxycarbonyl)-glycine (0.051 g, 0.171 mmol). The mixture was stirred for 30 min before a solution of Example 83A (0.05 g, 0.114 mmol) in 1 ml of 1:1 / dichloromethane:dimethylacetamide was added. The mixture was stirred 48 h at room temperature. PS-Trisamine resin (Argonaut, 100-200 mesh, 1% DVB, 4.06 mmol/g loading) (0.135 g, 0.55 mmol) was added and the mixture was agitated for 2 h. Piperidinomethyl polystyrene HL resin (NovaBiochem, 200-400 mesh, 2% DVB, 3.5 mmol/g loading) (0.244 g, 0.855 mmol) was added and the mixture was shaken for 7 days. The mixture was filtered through the Quest reaction tube and the residual resin was washed with dichloromethane (2×2 ml). The filtrate was concentrated to dryness and the residue was redissolved in 3 ml of 1:1/tetrahydrofuran:methanol. 2N aqueous sodium hydroxide solution (1 ml) was added and the mixture was shaken overnight. The mixture was neutralized with 4M hydrochloric acid in dioxane and concentrated to dryness. The residue was suspended in 1:1/dichloromethane:methanol (2 ml) and was filtered to remove any inorganics. The resulting clear solution was concentrated to dryness and was purified by preparative reverse phase HPLC (Waters Prep Nova-Pak HR C18 column, 25×100 mm, 6 μm, 60 Å, 0.01% trifluoroacetic acid in water:acetonitrile) to give the desired product (0.005 g, 12%) as an off-white solid.
