(en)TECHNICAL FIELD
The present invention relates to a compound having a calcium-sensing receptor (CaSR, hereinafter to be simply referred to as a calcium receptor) antagonistic action, a pharmaceutical composition containing the compound, particularly a calcium receptor antagonist and a therapeutic agent of osteoporosis.
BACKGROUND ART
Calcium receptors sense extracellular Ca 2+ concentration and increase intracellular Ca 2+ , thereby acting to suppress the production of parathyroid hormone (PTH) involved in the control of Ca 2+ metabolism and bone metabolism.
The serum calcium concentration of healthy mammal is strictly maintained at about 9-10 mg/100 ml (ca. 2.5 mM), which is referred to as calcium homeostasis of living organisms. When this value falls to not more than 50%, tetania occurs, and conversely, when it increases by 50%, consciousness is clouded, both cases threatening the lives. For maintaining calcium homeostasis, duodenum acts as a Ca 2+ uptake organ, bone acts as a Ca 2+ storage organ, and kidney acts as a Ca 2+ excretory organ. These Ca 2+ kinetics are controlled by various hormones generally referred to as “calcium controlling hormone”. Representative hormone includes active vitamin D [1 α , 25(OH) 2 D 3 ], PTH, calcitonin, Parathyroid Hormone-Related Protein (PTH-related Protein (PTHrP)) and the like.
Bone plays an important role not only as a supporting framework and motor organ of the body, but also as a storage organ of Ca 2+ , which is its constituent component. To fulfill such functions, bone tissues repeat formation thereof (osteogenesis) and absorption thereof (bone resorption) throughout the entire life. For osteogenesis, osteoblast derived from mesenchymal cell plays a major role, and for bone resorption, osteoclast derived from hematopoietic cell plays a major role. The mechanism of osteogenesis includes osteoid formation by bone organic matrix (bone matrix proteins such as type I collagen and the like) produced by osteoblast present on the osteogenesis surface, and subsequent calcification. On the other hand, the mechanism of bone resorption includes adhesion of osteoclast to the bone surface, intracellular absorption of Ca 2+ via protease acid secretion and ion transport, and excretion of absorbed Ca 2+ to the bone marrow side, thereby releasing Ca 2+ into blood. The deficient part of the bone absorbed by osteoclast is repaired by osteogenesis by osteoblast. This series of phenomena are called remodeling of bone, and by the remodeling, old bones are replaced by new bones, thus maintaining the strength of the entire bone while maintaining calcium homeostasis.
When blood Ca 2+ concentration increases, calcium receptor senses it, immediately suppresses secretion of PTH from the parathyroid gland to decrease the amount of Ca 2+ to be supplied into the blood [Brown, E. M., Homeostatic mechanisms regulating extracellular and intracellular calcium metabolism, in the parathyroids, p. 19, (1994), Raven press, New York]. Secretion of PTH is also suppressed by active vitamin D [1 α , 25(OH) 2 D 3 ].
Because PTH is a hormone assuming an important role in controlling Ca 2+ metabolism and bone metabolism, attempts have been made to apply PTH to the treatment of osteoporosis. In 1982, Tam et al. found that sustained administration of bovine PTH (1-84) to thyroid/parathyroid gland enucleated rat results in promotion of both osteogenesis and bone resorption of femoral cancellous bone, leading to a decrease in net bone mass, but subcutaneous intermittent administration thereof does not result in promotion of bone resorption but in promotion of osteogenesis alone, leading to an increase in the bone mass [Endocrinology, 110, 506-512 (1982)]. Furthermore, Uzawa et al. compared the actions of sustained administration and intermittent administration of PTH with regard to epiphyseal long bone and metaphyseal cancellous bone of young rat. As a result, they clarified that sustained administration of PTH results in remarkable increase in bone mass in metaphyseal cancellous bone highly susceptible to the effect of enchondral ossification, though associated with abnormal findings such as hyperplasia of epiphyseal plate cartilage, fibrous ostitis and the like, and in marked promotion of bone resorption and decrease in bone mass accompanied by rarefaction of cortical bone, in epiphyseal cancellous bone where the effect is small [Bone, 16, 477-484 (1995)]. In addition, it has been reported that intermittent administration of PTH results in significant increases in bone mass and bone trabecula in both epiphyseal and metaphyseal cancellous bones without increase in osteoclast or decrease of cortical bone.
Moreover, Scutt et al. have reported that, in chicken calvaria derived osteoblast, a short time (10-20 min) treatment with PTH promotes cell growth as compared to a long time (18 hr) treatment [Calcif. Tissue Int., 55, 208-215 (1994)]. This suggests that some of the actions of PTH on osteoblast are temporary and that expression of the action by the treatment for an extremely short time may be related to the fact that sustained administration and intermittent administration of PTH in vivo show different actions on bone tissues.
Ishizuya et al. further clarified through investigation of the action of PTH on differentiation of osteoblast using an in vitro experiment system that the action of PTH varies depending on the treatment time. They have reported that sustained action of PTH on osteoblast derived from rat calvaria resulted in strong inhibition of differentiation of osteoblast and nearly complete inhibition of osteogenesis in vitro, but repeated PTH action for the first 6 hr of 48 hr as one cycle resulted in significant promotion of differentiation of osteoblast and promotion of osteogenesis in vitro.
PTH is considered to not only prevent decrease in bone mass of osteoporosis model, but also has a bone mass recovery effect even on an animal already suffering from marked decrease in bone mass. Wronski et al. intermittently administered human PTH (1-34) to 90-day-old SD rat at 4 weeks post-ovariectomy and showing an obvious decrease in cancellous bone, for 15 weeks from 4 weeks post-ovariectomy. As a result, promotion of osteogenesis and inhibition of bone resorption were observed during the period of from week 5 to week 10 after the start of the administration, showing increased bone mass of about twice the bone mass of sham operation group [Endocrinology, 132, 823-831 (1993)]. They have also reported that, in this experiment, estrogen and bisphosphonate prevented decrease in bone mass caused by ovariectomy but did not show increase in bone mass, unlike PTH. They analyzed in detail the cortical bone of this experiment system and found images showing promoted osteogenesis and bone mass increase on the periost side and endosteum side by intermittent administration of human PTH (1-34), based on which they have clarified that the increase in cancellous bone due to PTH did not accompany decrease in cortical bone [Bone, 15, 51-58 (1994)].
Furthermore, Mosekilde et al. have reported that intermittent administration of human PTH (1-34) or human PTH (1-84) causes not only an increase in bone mass but also a dose-dependent increase in compression strength and bending strength, which are indices of bone substance, of cancellous bone [Endocrinology, 129, 421-428 (1991)] and cortical bone [J. Bone Miner. Res., 8, 1097-1101 (1993)] of rat vertebral bone. As discussed above, since PTH shows an obvious bone mass increasing action in experimental animals, various investigations are ongoing as regards the restrictive conditions expected in actual clinical applications. Mizoguchi studied whether or not a pharmacological effect is observed by intermittent administration of PTH, even when PTH in blood, which is considered to be one of the factors responsible for osteoporosis, has significantly increased, and concluded that the bone mass increased as usual [Journal of Japanese Society of Bone Morphometry, vol. 5, pp. 33-39 (1995)]. Takao et al. have studied the frequency of PTH administration and reported that administration of once a week for 12 weeks to healthy rat scarcely promoted bone resorption but dose-dependently increased the bone mass [Japanese Journal of Bone Metabolism, vol. 12 (Suppl.), p. S343 (1994)], suggesting possible effectiveness of clinically useful low frequency administration. The foregoing achievements suggest the possibility of PTH for making a potent and promising therapeutic drug for the treatment of postmenopausal osteoporosis or postovariectomy osteoporosis, which increases bone mass and decreases bone fracture rate.
These results clearly indicate that intermittent administration of PTH would enable treatment of osteoporosis. On the other hand, PTH problematically requires injection as an administration route, which is painful for many patients. However, an orally administrable pharmaceutical agent that can intermittently increase PTH concentration in blood is greatly expected to become a therapeutic drug of osteoporosis, which is based on a new action mechanism different from that of the above-mentioned PTH and conventional calcitonin.
Calcium receptor is a G protein coupled receptor, which is cloned as a molecule essential for controlling PTH secretion, and which penetrates cell membrane 7 times. Human calcium receptor consists of 1078 amino acids, and shows 93% amino acid homology with bovine calcium receptor. Human calcium receptor consists of a large N terminal extracellular region consisting of 612 amino acids, a cell membrane penetration region consisting of 250 amino acids and a C terminal intracellular region consisting of 216 amino acids.
Expression of calcium receptor has been found in parathyroid gland, kidney, thyroid C cell, brain and the like, as well as in bone (bone marrow cells).
When calcium receptor is bound with a ligand such as Ca 2+ and the like, it activates phospholipase C in conjugation with G protein, causes production of inositol triphosphate and increase in intracellular Ca 2+ concentration, and as a result, suppresses secretion of PTH [Nature, 366, 575-580 (1993)].
As mentioned above, a pharmaceutical agent that inhibits activation of calcium receptor, or a pharmaceutical agent that antagonizes calcium receptor, removes suppression of PTH secretion in parathyroid gland cells, and promotes secretion of PTH. It is considered that, if the antagonistic action can increase blood PTH concentration discontinuously and intermittently, its antagonist is expected to show the same effect as that provided by intermittent administration of PTH, and a pharmaceutical agent extremely effective for the treatment of osteoporosis can be provided.
In contrast, cytochrome (cytochrome P450, hereinafter P450) is a protein having a molecular weight of about 50,000, which contains protoheme, and its physical functions vary over a wide range. For example, it has a function of an enzyme catalyzing various reactions in the drug metabolism. CYP2D6 belonging to the family of P450 (CYP) is an important enzyme for human drug metabolism, and is involved in the metabolism of many compounds. When a drug inhibiting the metabolic function of CYP2D6 is administered, the drug is accumulated in the body and may exert a strong influence. Accordingly, a compound having a weak inhibitory action on the metabolic function of CYP2D6 is desirable as a drug.

Maxine Gowen et al. administered a compound having a CaSR antagonistic action, which is called NPS-2143,
to OVX rats orally and measured blood concentration and bone density thereof, thereby testing the effect of NPS-2143 on osteogenesis, and reported the results thereof (The Journal of Clinical Investigation, vol. 105, pp. 1595-1604 (2000)).
According to the report, NPS-2143 significantly promotes release of PTH, but it did not show any direct effect on osteoblast and osteoclast in vitro and was free of bone decrease or bone increase. One of the reasons pointed out therefor is too long a half-life of NPS-2143 in blood. That is, when rat PTH (1-34) was administered to OVX rat at the dose of 5 μg/kg, blood PTH concentration reached the peak of about 175 pg/ml in 30 minutes and returned to the original level in 2 hours, but when NPS-2143 was administered at the dose of 100 μmol/kg, the blood PTH concentration reached about 115 pg/ml in 30 minutes and kept increasing and showed about 140 pg/ml even 4 hours later (The Journal of Clinical Investigation, vol. 105, p.1595-1604 (2000), especially p. 1598, FIG. 3).
At that time, the blood concentration of NPS-2143 itself was maintained at the level of not less than 100 ng/ml even 8 hours after the administration. It was 24 hours later when the concentration became 10 ng/ml or below the undetectable level.
The above-mentioned Maxine Gowen et al. reference teaches that a calcium receptor antagonist having a too long blood half-life provides results as in continuous administration of PTH, where a bone mass increase cannot be expected. Thus, most of the conventional calcium receptor antagonists continuously increase the blood PTH concentration and cannot be expected to provide a sufficient osteogenesis promoting action. Of the conventional calcium receptor antagonists, a compound represented by the following formula [I]
wherein R 1 is optionally substituted aryl group etc., R 2 is C 1-6 alkyl group, C 3-7 cycloalkyl group etc., R 3 is hydroxyl group etc., R 4 is hydrogen atom etc., R 5 and R 6 are C 1-6 alkyl group etc., R 7 is optionally substituted aryl group etc., X 1 is a single bond, C 1-6 alkylene etc., X 2 is optionally substituted C 1-6 alkylene, X 3 is a single bond or optionally substituted C 1-6 alkylene, and X 4 and X 5 are linked to form a single bond, methylene etc., which has a superior calcium receptor antagonistic action, which can be administered orally and intermittently, and which can increase blood PTH concentration discontinuously and intermittently, is disclosed (WO02/14259). By comparison of the activities of a compound within the scope disclosed in this publication and the compound of the present invention, the compound of the present invention was surprisingly found to have a higher activity and to be a compound having a lower inhibitory action on the metabolic enzyme CYP2D6.
However, there are not many reports on such an effective compound, and further study is desired.

EXPERIMENTAL EXAMPLES
The bioactivity of the compound of the present invention was examined by tests.
Experimental Example 1
Evaluation of Antagonistic Action on Calcium Receptor Using Reporter Gene
Luciferase cDNA and human calcium receptor cDNA were introduced into a cell strain derived from rat adrenal to transform the cells, and the transformed cells were cultured in a medium (80 μl, F12 medium containing 0.5% dialyzed horse serum and 0.25% dialyzed bovine fetal serum). A dimethyl sulfoxide solution containing a test compound at 0.1-10000 μM was diluted 100-fold with the medium and added to the test compound group at 10 μl per well (dimethyl sulfoxide final concentration 0.1%). In the same manner as in test compound group, dimethyl sulfoxide 100-fold diluted with medium was added to a control group and a blank group. Then, 50 mM calcium chloride-containing medium was added to every well except the blank group at 10 μl per well (final concentration 5 mM). A medium containing 50 mM calcium chloride was added to the control group at 10 μl per well, such that the final calcium concentration of the medium became 5 mM. A medium alone was added to the blank group. After culture for 4 hrs, luciferase substrate was added and the luciferase activity was measured with a photoluminometer. The inhibitory rate (%) was calculated from the obtained measured values according to the following formula.
Inhibitory rate ( % ) = 100 - measured value of compound group - measured value of blank group measured value of control group - measured value of blank group × 100
Based on the results, the concentration (IC 50 ) showing 50% inhibitory rate was determined. The results are shown in the aforementioned Tables 1 to 60.

Effect of Concomitant Administration of Test Compound and Estrogen on Bone Resorption and PTH Secretion
The 13-week-old ovariectomized rats were divided into 4 groups of a control group (Group A), an estrogen administration group (Group B), a test compound administration group (Group C), and a test compound and estrogen concomitant administration group (Group D). One sham control group (E group) subjected to a sham surgery was also established. Estradiol was dissolved in 5% benzyl alcohol-corn oil and subcutaneously administered to an estrogen administration groups (Group B and Group D) at the dose of 10 μg/kg. 5% Benzyl alcohol-corn oil was subcutaneously administered to groups (Group A and Group C) free from administration of estrogen. The compound of Example 1-1 was suspended in 0.5% methyl cellulose solution and orally administered to groups (Group C and Group D) to be administered with the test compound at the dose of 3 mg/kg. As regards the groups (Group A and Group B) free from administration of the test compound, 0.5% methyl cellulose solution was orally administered.
On day 13 from the start of the administration, the blood was drawn in each group from the tail vein, and serum was obtained. ICTP, which is a blood bone resorption marker, was measured using a commercially available ELISA kit (“RatLaps ELISA kit”, Nordic Bioscience Diagnostics).
In addition, blood was drawn with time for the measurement of blood PTH at day 16 of administration. The blood was drawn in each group from the tail vein immediately before oral administration and 0.25, 0.5, 1, 2 and 4 hr later, and serum was obtained. For serum PTH measurement, a commercially available ELISA kit (“rat intact PTH ELISA kit”, Immutopics) was used.
The measurement results of blood ICTP are shown in Table 65 and the blood PTH measurement results are shown in Table 66.

When osteoporosis is to be treated by increasing the blood PTH concentration based on inhibition of the action of calcium receptor, the compound to be used for this end should have at least the following properties.
(i) The compound has a sufficient antagonistic action on calcium receptors. In other words, the compound has a sufficiently low IC 50 value. In the specification of WO99/51241, it is described, “In general, a compound showing a low IC 50 value in the assay of calcium receptor inhibitor is a more superior compound. A compound showing an IC 50 value of not lower than 50 μM is considered to be inactive. A preferable compound shows an IC 50 value of not more than 10 μM, more preferably 1 μM, and most preferably not more than 0.1 μM.” (ii) Administration of the compound results in a sufficient increase in the blood PTH concentration. (iii) The time-course concentrations in blood after administration of the compound are not sustainable. Desirably, the PTH concentration returns to the level before administration in 3-4 hr after administration of the compound.
Moreover, it is preferable to satisfy the following two aspects;
(1) Administration of the compound does not inhibit the action of bone resorption suppressants such as estrogen and the like. (2) The PTH secretion action of the compound is not inhibited by bone resorption suppressants such as estrogen and the like.
As regards (i); as shown in Tables 1 to 60, the IC 50 value of the compound of the present invention is not more than 1 μM, and the compound has a sufficient antagonistic action on calcium receptors. The compound of the present invention is considered to be preferable in view of the IC 50 value.
As regards (ii); as shown in Tables 61 and 62, the serum PTH concentration 15 min later was 1.8-3.3 times higher (compound wherein n=0) and 1.8 times higher (compound wherein n=1) than control, and the compound of the present invention has been confirmed to have a superior PTH secretion promoting action.
As regards (iii); as shown in Table 61, PTH secretion by the compound of the present invention reached a peak at 15 min after administration, sharply decreased thereafter and returned to the blood PTH concentration before administration in about 1-2 hr. It is clear from this aspect that the compound of the present invention is superior. In contrast, as a result of the reproductive test of NPS-2143 of the reference, the sustained secretion promoting action of NPS-2143 was confirmed.
From the foregoing test results, it is clear that the compounds of the present invention satisfies the above-mentioned properties.
As regards (1); as shown in Table 65, comparison of the sham control group subjected to a sham surgery and the control group reveals an increase in ICTP due to ovary enucleation, thereby confirming promoted bone resorption. This increase was suppressed by an exclusive administration of estrogen, and concomitant administration of Example 1-1 did not show changes in the ability to suppress estrogen.
As regards (2); as shown in Table 66, there was found no difference in blood PTH value before administration between the groups. By examination of the changes with time, increase in blood PTH was not observed by estrogen exclusive administration, but a transitional increase was observed in both the Example 1-1 exclusive group and Example 1-1 and estrogen concomitant administration group.
INDUSTRIAL APPLICABILITY
As is clear from the above-mentioned Experimental Example 1, the compound of the formula (1) of the present invention has a superior calcium receptor antagonistic action. Accordingly, the compound is expected to be useful as a therapeutic drug for diseases accompanied by abnormal calcium homeostasis, such as osteoporosis, hypoparathyreosis, osteosarcoma, periodontal disease, bone fracture, osteoarthrisis, chronic rheumatoid arthritis, Paget's disease, humoral hypercalcemia, autosomal dominant hypocalcemia, Parkinson's disease, dimentia and the like. As is clear from Experimental Examples 2 and 3, the compound of the present invention has a temporary PTH secretion promoting action, and as is clear from Experimental Example 4, it has weak metabolic enzyme CYP2D6 inhibitory activity. Accordingly, the compound is particularly useful as a therapeutic agent for osteoporosis.
As is clear from Experimental Example 5, moreover, the compound of the present invention does not inhibit the action of bone resorption suppressants such as estrogen and the like, and the PTH secretion action of the compound of the present invention is not inhibited by bone resorption suppressants such as estrogen and the like. Therefore, use of the compound of the present invention and bone resorption suppressants such as estrogen and the like in combination is considered to be extremely effective for osteoporosis.

(en)TECHNICAL FIELD
The present invention relates to a compound having a calcium-sensing receptor (CaSR, hereinafter to be simply referred to as a calcium receptor) antagonistic action, a pharmaceutical composition containing the compound, particularly a calcium receptor antagonist and a therapeutic agent of osteoporosis.
BACKGROUND ART
Calcium receptors sense extracellular Ca 2+ concentration and increase intracellular Ca 2+ , thereby acting to suppress the production of parathyroid hormone (PTH) involved in the control of Ca 2+ metabolism and bone metabolism.
The serum calcium concentration of healthy mammal is strictly maintained at about 9-10 mg/100 ml (ca. 2.5 mM), which is referred to as calcium homeostasis of living organisms. When this value falls to not more than 50%, tetania occurs, and conversely, when it increases by 50%, consciousness is clouded, both cases threatening the lives. For maintaining calcium homeostasis, duodenum acts as a Ca 2+ uptake organ, bone acts as a Ca 2+ storage organ, and kidney acts as a Ca 2+ excretory organ. These Ca 2+ kinetics are controlled by various hormones generally referred to as “calcium controlling hormone”. Representative hormone includes active vitamin D [1 α , 25(OH) 2 D 3 ], PTH, calcitonin, Parathyroid Hormone-Related Protein (PTH-related Protein (PTHrP)) and the like.
Bone plays an important role not only as a supporting framework and motor organ of the body, but also as a storage organ of Ca 2+ , which is its constituent component. To fulfill such functions, bone tissues repeat formation thereof (osteogenesis) and absorption thereof (bone resorption) throughout the entire life. For osteogenesis, osteoblast derived from mesenchymal cell plays a major role, and for bone resorption, osteoclast derived from hematopoietic cell plays a major role. The mechanism of osteogenesis includes osteoid formation by bone organic matrix (bone matrix proteins such as type I collagen and the like) produced by osteoblast present on the osteogenesis surface, and subsequent calcification. On the other hand, the mechanism of bone resorption includes adhesion of osteoclast to the bone surface, intracellular absorption of Ca 2+ via protease acid secretion and ion transport, and excretion of absorbed Ca 2+ to the bone marrow side, thereby releasing Ca 2+ into blood. The deficient part of the bone absorbed by osteoclast is repaired by osteogenesis by osteoblast. This series of phenomena are called remodeling of bone, and by the remodeling, old bones are replaced by new bones, thus maintaining the strength of the entire bone while maintaining calcium homeostasis.
When blood Ca 2+ concentration increases, calcium receptor senses it, immediately suppresses secretion of PTH from the parathyroid gland to decrease the amount of Ca 2+ to be supplied into the blood [Brown, E. M., Homeostatic mechanisms regulating extracellular and intracellular calcium metabolism, in the parathyroids, p. 19, (1994), Raven press, New York]. Secretion of PTH is also suppressed by active vitamin D [1 α , 25(OH) 2 D 3 ].
Because PTH is a hormone assuming an important role in controlling Ca 2+ metabolism and bone metabolism, attempts have been made to apply PTH to the treatment of osteoporosis. In 1982, Tam et al. found that sustained administration of bovine PTH (1-84) to thyroid/parathyroid gland enucleated rat results in promotion of both osteogenesis and bone resorption of femoral cancellous bone, leading to a decrease in net bone mass, but subcutaneous intermittent administration thereof does not result in promotion of bone resorption but in promotion of osteogenesis alone, leading to an increase in the bone mass [Endocrinology, 110, 506-512 (1982)]. Furthermore, Uzawa et al. compared the actions of sustained administration and intermittent administration of PTH with regard to epiphyseal long bone and metaphyseal cancellous bone of young rat. As a result, they clarified that sustained administration of PTH results in remarkable increase in bone mass in metaphyseal cancellous bone highly susceptible to the effect of enchondral ossification, though associated with abnormal findings such as hyperplasia of epiphyseal plate cartilage, fibrous ostitis and the like, and in marked promotion of bone resorption and decrease in bone mass accompanied by rarefaction of cortical bone, in epiphyseal cancellous bone where the effect is small [Bone, 16, 477-484 (1995)]. In addition, it has been reported that intermittent administration of PTH results in significant increases in bone mass and bone trabecula in both epiphyseal and metaphyseal cancellous bones without increase in osteoclast or decrease of cortical bone.
Moreover, Scutt et al. have reported that, in chicken calvaria derived osteoblast, a short time (10-20 min) treatment with PTH promotes cell growth as compared to a long time (18 hr) treatment [Calcif. Tissue Int., 55, 208-215 (1994)]. This suggests that some of the actions of PTH on osteoblast are temporary and that expression of the action by the treatment for an extremely short time may be related to the fact that sustained administration and intermittent administration of PTH in vivo show different actions on bone tissues.
Ishizuya et al. further clarified through investigation of the action of PTH on differentiation of osteoblast using an in vitro experiment system that the action of PTH varies depending on the treatment time. They have reported that sustained action of PTH on osteoblast derived from rat calvaria resulted in strong inhibition of differentiation of osteoblast and nearly complete inhibition of osteogenesis in vitro, but repeated PTH action for the first 6 hr of 48 hr as one cycle resulted in significant promotion of differentiation of osteoblast and promotion of osteogenesis in vitro.
PTH is considered to not only prevent decrease in bone mass of osteoporosis model, but also has a bone mass recovery effect even on an animal already suffering from marked decrease in bone mass. Wronski et al. intermittently administered human PTH (1-34) to 90-day-old SD rat at 4 weeks post-ovariectomy and showing an obvious decrease in cancellous bone, for 15 weeks from 4 weeks post-ovariectomy. As a result, promotion of osteogenesis and inhibition of bone resorption were observed during the period of from week 5 to week 10 after the start of the administration, showing increased bone mass of about twice the bone mass of sham operation group [Endocrinology, 132, 823-831 (1993)]. They have also reported that, in this experiment, estrogen and bisphosphonate prevented decrease in bone mass caused by ovariectomy but did not show increase in bone mass, unlike PTH. They analyzed in detail the cortical bone of this experiment system and found images showing promoted osteogenesis and bone mass increase on the periost side and endosteum side by intermittent administration of human PTH (1-34), based on which they have clarified that the increase in cancellous bone due to PTH did not accompany decrease in cortical bone [Bone, 15, 51-58 (1994)].
Furthermore, Mosekilde et al. have reported that intermittent administration of human PTH (1-34) or human PTH (1-84) causes not only an increase in bone mass but also a dose-dependent increase in compression strength and bending strength, which are indices of bone substance, of cancellous bone [Endocrinology, 129, 421-428 (1991)] and cortical bone [J. Bone Miner. Res., 8, 1097-1101 (1993)] of rat vertebral bone. As discussed above, since PTH shows an obvious bone mass increasing action in experimental animals, various investigations are ongoing as regards the restrictive conditions expected in actual clinical applications. Mizoguchi studied whether or not a pharmacological effect is observed by intermittent administration of PTH, even when PTH in blood, which is considered to be one of the factors responsible for osteoporosis, has significantly increased, and concluded that the bone mass increased as usual [Journal of Japanese Society of Bone Morphometry, vol. 5, pp. 33-39 (1995)]. Takao et al. have studied the frequency of PTH administration and reported that administration of once a week for 12 weeks to healthy rat scarcely promoted bone resorption but dose-dependently increased the bone mass [Japanese Journal of Bone Metabolism, vol. 12 (Suppl.), p. S343 (1994)], suggesting possible effectiveness of clinically useful low frequency administration. The foregoing achievements suggest the possibility of PTH for making a potent and promising therapeutic drug for the treatment of postmenopausal osteoporosis or postovariectomy osteoporosis, which increases bone mass and decreases bone fracture rate.
These results clearly indicate that intermittent administration of PTH would enable treatment of osteoporosis. On the other hand, PTH problematically requires injection as an administration route, which is painful for many patients. However, an orally administrable pharmaceutical agent that can intermittently increase PTH concentration in blood is greatly expected to become a therapeutic drug of osteoporosis, which is based on a new action mechanism different from that of the above-mentioned PTH and conventional calcitonin.
Calcium receptor is a G protein coupled receptor, which is cloned as a molecule essential for controlling PTH secretion, and which penetrates cell membrane 7 times. Human calcium receptor consists of 1078 amino acids, and shows 93% amino acid homology with bovine calcium receptor. Human calcium receptor consists of a large N terminal extracellular region consisting of 612 amino acids, a cell membrane penetration region consisting of 250 amino acids and a C terminal intracellular region consisting of 216 amino acids.
Expression of calcium receptor has been found in parathyroid gland, kidney, thyroid C cell, brain and the like, as well as in bone (bone marrow cells).
When calcium receptor is bound with a ligand such as Ca 2+ and the like, it activates phospholipase C in conjugation with G protein, causes production of inositol triphosphate and increase in intracellular Ca 2+ concentration, and as a result, suppresses secretion of PTH [Nature, 366, 575-580 (1993)].
As mentioned above, a pharmaceutical agent that inhibits activation of calcium receptor, or a pharmaceutical agent that antagonizes calcium receptor, removes suppression of PTH secretion in parathyroid gland cells, and promotes secretion of PTH. It is considered that, if the antagonistic action can increase blood PTH concentration discontinuously and intermittently, its antagonist is expected to show the same effect as that provided by intermittent administration of PTH, and a pharmaceutical agent extremely effective for the treatment of osteoporosis can be provided.
In contrast, cytochrome (cytochrome P450, hereinafter P450) is a protein having a molecular weight of about 50,000, which contains protoheme, and its physical functions vary over a wide range. For example, it has a function of an enzyme catalyzing various reactions in the drug metabolism. CYP2D6 belonging to the family of P450 (CYP) is an important enzyme for human drug metabolism, and is involved in the metabolism of many compounds. When a drug inhibiting the metabolic function of CYP2D6 is administered, the drug is accumulated in the body and may exert a strong influence. Accordingly, a compound having a weak inhibitory action on the metabolic function of CYP2D6 is desirable as a drug.

Maxine Gowen et al. administered a compound having a CaSR antagonistic action, which is called NPS-2143,
to OVX rats orally and measured blood concentration and bone density thereof, thereby testing the effect of NPS-2143 on osteogenesis, and reported the results thereof (The Journal of Clinical Investigation, vol. 105, pp. 1595-1604 (2000)).
According to the report, NPS-2143 significantly promotes release of PTH, but it did not show any direct effect on osteoblast and osteoclast in vitro and was free of bone decrease or bone increase. One of the reasons pointed out therefor is too long a half-life of NPS-2143 in blood. That is, when rat PTH (1-34) was administered to OVX rat at the dose of 5 μg/kg, blood PTH concentration reached the peak of about 175 pg/ml in 30 minutes and returned to the original level in 2 hours, but when NPS-2143 was administered at the dose of 100 μmol/kg, the blood PTH concentration reached about 115 pg/ml in 30 minutes and kept increasing and showed about 140 pg/ml even 4 hours later (The Journal of Clinical Investigation, vol. 105, p.1595-1604 (2000), especially p. 1598, FIG. 3).
At that time, the blood concentration of NPS-2143 itself was maintained at the level of not less than 100 ng/ml even 8 hours after the administration. It was 24 hours later when the concentration became 10 ng/ml or below the undetectable level.
The above-mentioned Maxine Gowen et al. reference teaches that a calcium receptor antagonist having a too long blood half-life provides results as in continuous administration of PTH, where a bone mass increase cannot be expected. Thus, most of the conventional calcium receptor antagonists continuously increase the blood PTH concentration and cannot be expected to provide a sufficient osteogenesis promoting action. Of the conventional calcium receptor antagonists, a compound represented by the following formula [I]
wherein R 1 is optionally substituted aryl group etc., R 2 is C 1-6 alkyl group, C 3-7 cycloalkyl group etc., R 3 is hydroxyl group etc., R 4 is hydrogen atom etc., R 5 and R 6 are C 1-6 alkyl group etc., R 7 is optionally substituted aryl group etc., X 1 is a single bond, C 1-6 alkylene etc., X 2 is optionally substituted C 1-6 alkylene, X 3 is a single bond or optionally substituted C 1-6 alkylene, and X 4 and X 5 are linked to form a single bond, methylene etc., which has a superior calcium receptor antagonistic action, which can be administered orally and intermittently, and which can increase blood PTH concentration discontinuously and intermittently, is disclosed (WO02/14259). By comparison of the activities of a compound within the scope disclosed in this publication and the compound of the present invention, the compound of the present invention was surprisingly found to have a higher activity and to be a compound having a lower inhibitory action on the metabolic enzyme CYP2D6.
However, there are not many reports on such an effective compound, and further study is desired.

EXPERIMENTAL EXAMPLES
The bioactivity of the compound of the present invention was examined by tests.
Experimental Example 1
Evaluation of Antagonistic Action on Calcium Receptor Using Reporter Gene
Luciferase cDNA and human calcium receptor cDNA were introduced into a cell strain derived from rat adrenal to transform the cells, and the transformed cells were cultured in a medium (80 μl, F12 medium containing 0.5% dialyzed horse serum and 0.25% dialyzed bovine fetal serum). A dimethyl sulfoxide solution containing a test compound at 0.1-10000 μM was diluted 100-fold with the medium and added to the test compound group at 10 μl per well (dimethyl sulfoxide final concentration 0.1%). In the same manner as in test compound group, dimethyl sulfoxide 100-fold diluted with medium was added to a control group and a blank group. Then, 50 mM calcium chloride-containing medium was added to every well except the blank group at 10 μl per well (final concentration 5 mM). A medium containing 50 mM calcium chloride was added to the control group at 10 μl per well, such that the final calcium concentration of the medium became 5 mM. A medium alone was added to the blank group. After culture for 4 hrs, luciferase substrate was added and the luciferase activity was measured with a photoluminometer. The inhibitory rate (%) was calculated from the obtained measured values according to the following formula.
Inhibitory rate ( % ) = 100 - measured value of compound group - measured value of blank group measured value of control group - measured value of blank group × 100
Based on the results, the concentration (IC 50 ) showing 50% inhibitory rate was determined. The results are shown in the aforementioned Tables 1 to 60.

Effect of Concomitant Administration of Test Compound and Estrogen on Bone Resorption and PTH Secretion
The 13-week-old ovariectomized rats were divided into 4 groups of a control group (Group A), an estrogen administration group (Group B), a test compound administration group (Group C), and a test compound and estrogen concomitant administration group (Group D). One sham control group (E group) subjected to a sham surgery was also established. Estradiol was dissolved in 5% benzyl alcohol-corn oil and subcutaneously administered to an estrogen administration groups (Group B and Group D) at the dose of 10 μg/kg. 5% Benzyl alcohol-corn oil was subcutaneously administered to groups (Group A and Group C) free from administration of estrogen. The compound of Example 1-1 was suspended in 0.5% methyl cellulose solution and orally administered to groups (Group C and Group D) to be administered with the test compound at the dose of 3 mg/kg. As regards the groups (Group A and Group B) free from administration of the test compound, 0.5% methyl cellulose solution was orally administered.
On day 13 from the start of the administration, the blood was drawn in each group from the tail vein, and serum was obtained. ICTP, which is a blood bone resorption marker, was measured using a commercially available ELISA kit (“RatLaps ELISA kit”, Nordic Bioscience Diagnostics).
In addition, blood was drawn with time for the measurement of blood PTH at day 16 of administration. The blood was drawn in each group from the tail vein immediately before oral administration and 0.25, 0.5, 1, 2 and 4 hr later, and serum was obtained. For serum PTH measurement, a commercially available ELISA kit (“rat intact PTH ELISA kit”, Immutopics) was used.
The measurement results of blood ICTP are shown in Table 65 and the blood PTH measurement results are shown in Table 66.

When osteoporosis is to be treated by increasing the blood PTH concentration based on inhibition of the action of calcium receptor, the compound to be used for this end should have at least the following properties.
(i) The compound has a sufficient antagonistic action on calcium receptors. In other words, the compound has a sufficiently low IC 50 value. In the specification of WO99/51241, it is described, “In general, a compound showing a low IC 50 value in the assay of calcium receptor inhibitor is a more superior compound. A compound showing an IC 50 value of not lower than 50 μM is considered to be inactive. A preferable compound shows an IC 50 value of not more than 10 μM, more preferably 1 μM, and most preferably not more than 0.1 μM.” (ii) Administration of the compound results in a sufficient increase in the blood PTH concentration. (iii) The time-course concentrations in blood after administration of the compound are not sustainable. Desirably, the PTH concentration returns to the level before administration in 3-4 hr after administration of the compound.
Moreover, it is preferable to satisfy the following two aspects;
(1) Administration of the compound does not inhibit the action of bone resorption suppressants such as estrogen and the like. (2) The PTH secretion action of the compound is not inhibited by bone resorption suppressants such as estrogen and the like.
As regards (i); as shown in Tables 1 to 60, the IC 50 value of the compound of the present invention is not more than 1 μM, and the compound has a sufficient antagonistic action on calcium receptors. The compound of the present invention is considered to be preferable in view of the IC 50 value.
As regards (ii); as shown in Tables 61 and 62, the serum PTH concentration 15 min later was 1.8-3.3 times higher (compound wherein n=0) and 1.8 times higher (compound wherein n=1) than control, and the compound of the present invention has been confirmed to have a superior PTH secretion promoting action.
As regards (iii); as shown in Table 61, PTH secretion by the compound of the present invention reached a peak at 15 min after administration, sharply decreased thereafter and returned to the blood PTH concentration before administration in about 1-2 hr. It is clear from this aspect that the compound of the present invention is superior. In contrast, as a result of the reproductive test of NPS-2143 of the reference, the sustained secretion promoting action of NPS-2143 was confirmed.
From the foregoing test results, it is clear that the compounds of the present invention satisfies the above-mentioned properties.
As regards (1); as shown in Table 65, comparison of the sham control group subjected to a sham surgery and the control group reveals an increase in ICTP due to ovary enucleation, thereby confirming promoted bone resorption. This increase was suppressed by an exclusive administration of estrogen, and concomitant administration of Example 1-1 did not show changes in the ability to suppress estrogen.
As regards (2); as shown in Table 66, there was found no difference in blood PTH value before administration between the groups. By examination of the changes with time, increase in blood PTH was not observed by estrogen exclusive administration, but a transitional increase was observed in both the Example 1-1 exclusive group and Example 1-1 and estrogen concomitant administration group.
INDUSTRIAL APPLICABILITY
As is clear from the above-mentioned Experimental Example 1, the compound of the formula (1) of the present invention has a superior calcium receptor antagonistic action. Accordingly, the compound is expected to be useful as a therapeutic drug for diseases accompanied by abnormal calcium homeostasis, such as osteoporosis, hypoparathyreosis, osteosarcoma, periodontal disease, bone fracture, osteoarthrisis, chronic rheumatoid arthritis, Paget's disease, humoral hypercalcemia, autosomal dominant hypocalcemia, Parkinson's disease, dimentia and the like. As is clear from Experimental Examples 2 and 3, the compound of the present invention has a temporary PTH secretion promoting action, and as is clear from Experimental Example 4, it has weak metabolic enzyme CYP2D6 inhibitory activity. Accordingly, the compound is particularly useful as a therapeutic agent for osteoporosis.
As is clear from Experimental Example 5, moreover, the compound of the present invention does not inhibit the action of bone resorption suppressants such as estrogen and the like, and the PTH secretion action of the compound of the present invention is not inhibited by bone resorption suppressants such as estrogen and the like. Therefore, use of the compound of the present invention and bone resorption suppressants such as estrogen and the like in combination is considered to be extremely effective for osteoporosis.
This application is based on a patent application No. 119131/2003 filed in Japan, the contents of which are hereby incorporated by reference.
