## Title
Pharmaceutical composition for preventing and treating metabolic bone diseases containing alpha-arylmethoxyactylate derivatives

## Abstract

The present invention relates to a use of a specific alpha-arylmethoxyacrylate derivative, or its pharmacologically acceptable salt or solvate for preventing and treating metabolic bone diseases.

## Background
This is a national stage application under 35 U.S.C. 371 of PCT/KR2005/01935 filed on Jun. 22, 2005, which claims priority from Korean patent application 10-2004-0046644 filed on Jun. 22, 2004, all of which are incorporated herein by reference.
FIELD OF THE INVENTION
The present invention relates to a pharmaceutical composition for preventing and treating metabolic bone diseases which contains an alpha-arylmethoxyacrylate derivative, or its pharmacologically acceptable salt or solvate as an active ingredient.
DESCRIPTION OF THE PRIOR ART
Metabolic bone diseases such as osteoporosis are typically caused by reduction of protein, calcium, phosphor and others in bones. Osteoporosis occurs regardless of age and sex with increasing frequency upon aging, especially in a high frequency in postmenopausal women. Recently, the number of osteoporosis patient has been increasing due to the aging of global population and, accordingly, there has existed a need for developing an efficacious medicament for preventing and treating osteoporosis.
Currently available therapeutic agents for osteoporosis include bisphosphonates, hormonal drugs, vitamin D and its analogues, calcitonin, and calcium. Representative bisphosphonates include alendronate (Merck and Co., Ltd.), risedronate (Hoffman-La Roche Ltd.), zoledronate (Novatis A G; EP Patent No. 275,821), ibandronate (Hoffman-La Roche Ltd.; U.S. Pat. No. 4,942,157) and minodronate (Yamanouchi Pharmaceutical Co., Ltd.; EP Patent No. 354,806). Bisphosphonates are major therapeutic agents for osteoporosis; however, they have the disadvantages of low absorption rates through the gastrointestinal tract and possibility of causing esophagitis when not keeping the complicated administration guidance.
Exemplary hormonal drugs include raloxifene (Eli Lilly and Co.), droloxyfene (Pfizer Inc.; EP Patent No. 54168), lasopoxifene (Pfizer Inc.), FC-1271 (homosmedical Co. and Orion Corp., WO 96/07402), TES-424 (Ligand Co. and Weyers Co., U.S. Pat. No. 5,948,775). However, hormonal drugs have the risk of causing breast and uterine cancers and, accordingly, they are limitedly used as a therapeutic agent for osteoporosis which requires a long-term administration.
Further, vitamin D and its analogues are expensive and the therapeutic efficacy for osteoporosis thereof is not clearly established; calcitonin is relatively expensive and requires a difficult administration way; and calcium is known to cause little side effects, but is effective only for the prevention of osteoporosis, having no therapeutic effect.
SUMMARY OF THE INVENTION
Accordingly, it is a primary object of the present invention to provide a novel pharmaceutical composition for preventing and treating a metabolic bone disease having good activity and low side-effects.
In accordance with one aspect of the present invention, there is provided a pharmaceutical composition for preventing and treating metabolic bone diseases comprising a compound of formula (1), or its pharmacologically acceptable salt or solvate as an active ingredient:




wherein,

    A is O, S, CH2, O—N═CH or O—N═C(CH3);
    X is H, or a halogen;
    Y is N or CH;
    Z is O or NH;
    R1 is H or C1 ̃4 alkyl;
    R2 is unsubstituted or substituted aryl or heteroaryl.


In accordance with another aspect of the present invention, there is provided a use of the compound of formula (1), or its pharmacologically acceptable salt or solvate for preventing and treating metabolic bone diseases.
In accordance with a further aspect of the present invention, there is provided a method for preventing and treating metabolic bone diseases using the compound of formula (1), or its pharmacologically acceptable salt or solvate.



BRIEF DESCRIPTION OF THE DRAWINGS
The above and other objects and features of the present invention will become apparent from the following description thereof, when taken in conjunction with the accompanying drawings which respectively show:
FIGS. 1a and 1b: the changes in bone mineral density (BMD) of multiparous mice ovariectomized to induce osteoporosis observed when the mice were subcutaneously injected with compounds according to the present invention; and
FIGS. 2a and 2b: the changes in BMD of multiparous mice ovariectomized to induce osteoporosis observed when the mice were orally administered with compounds according to the present invention.



DETAILED DESCRIPTION OF THE INVENTION
In the compound of formula (1), R2 may be an aryl group such as phenyl or naphthyl, or a 5- or 6-membered heterocyclic aromatic ring containing at least one element selected from O, S and N, such as pyridine, pyrimidine, oxazolone, 1,3,4-thiadiazole, cromene, indole, morpholine, thiomorpholine, pyrrolidine, piperidine, piperazine, N-methylpiperazine, N-acetylpiperazine, pyrrolidone, piperidone, oxazolidinone, thiazolidinone, and imidazolone.
Such an aryl or heteroaryl group represented by R2 may be substituted with at least one substituent selected from the group consisting of halogens, cyano, nitro, C1 ̃4 haloalkyl, C1 ̃4 haloalkenyl, hydroxy, C1 ̃8 alkyl, C2 ̃8 alkenyl, C2 ̃4 alkynyl, C3 ̃6 cycloalkyl, C1 ̃8 alkoxy, C1 ̃4 alkoxy C1 ̃4 alkyl, C3 ̃6 cycloalkyl C1 ̃4 alkyl, C1 ̃4 dialkoxy C1 ̃4 alkyl, 1,3-dioxolan-2-yl, 1,3-dioxan-2-yl, C2 ̃8 alkenyloxy, C2 ̃4 alkynyloxy, C3 ̃6 cycloalkyl C1 ̃4 alkoxy, hydroxy C1 ̃4 alkyl, C1 ̃4 acyloxy, C1 ̃4 alkylcarbonyl, C1 ̃4 alkylcarbonyloxy, C3 ̃6 cycloalkylcarbonyloxy, C1 ̃4 alkoxycarbonyl, C1 ̃4 dialkylamino C1 ̃4 alkoxy, at least one N or O-containing C2 ̃5 heterocyclo C1 ̃4 alkoxy, 2-morpholinoethoxy, 2-(piperidin-1-yl)ethoxy), unsubstituted or substituted N-containing heteroaryl, unsubstituted or substituted amino, and unsubstituted or substituted amino C1 ̃2 alkyl.
The unsubstituted or substituted amino or amino C1 ̃2 alkyl is represented by —(CH2)n—NR3R4, wherein n is 0, 1 or 2, R3 and R4 are each independently H, C1 ̃8 alkyl, C1 ̃8 haloalkyl, hydroxy, C2 ̃8 alkenyl, C2 ̃4 alkynyl, C3 ̃8 cycloalkyl, C3 ̃8 cycloalkyl C1 ̃4 alkyl, C1 ̃4 alkoxy C1 ̃4 alkyl, C3 ̃8 cycloalkoxy C1 ̃4 alkyl, C1 ̃8 alkylsulfonyl, at least one N, O or S-containing C2 ̃7 heterocyclic C1 ̃4 alkyl, or an optionally substituted aryl; or R3 and R4 may be fused together with the nitrogen atom to which they are attached to form a heterocyclic ring.

Step 3)
In a dried reactor, 63 mg (0.46 mmol) of K2CO3 and 50 mg (0.30 mmol) of the compound obtained in Step 2 were added to 4 ml of acetonitrile. The resulting mixture was stirred for 20 min, and 104 mg (0.36 mmol) of (E)-methyl-2-(2-bromomethyl)phenyl)-3-methoxy acrylate was added thereto. The resulting mixture was refluxed for 16 hours, cooled, distilled under a reduced pressure to remove the solvent, and then 10 ml of ethyl acetate was added thereto. The organic layer was separated, washed twice with water, dried over anhydrous MgSO4, and concentrated under a reduced pressure. The residue was subjected to column chromatography using 30% ethyl acetate/hexane as an eluent to obtain 70 mg (yield 64%) of (E)-methyl-2-[2-((6-(pyrrolidin-1-yl)pyridin-2-yloxy)methyl)phenyl]-3-methoxyacrylate.

TEST EXAMPLE 1
Inhibitory Effect on Osteoclast Formation
The inhibitory activities of the alpha-arylmethoxyacrylate derivatives prepared in the above Examples on the proliferation of osteoclasts were examined as follows.
(1-1) Isolation of Osteoclast Pregenitors and Induction of their Differentiation to Mature Osteoclasts
First, a bone marrow sample containing osteoclast pregenitor cells was isolated as follows. After sacrificing 7 to 9 week-old female mice by cervical dislocation, femur and tibia were excised aseptically while removing soft tissues attached thereto, After cutting both ends of the long bones, 1 ml of an enzyme solution containing 0.1% collagenase (Gibco), 0.05% trypsin and 0.5 mM EDTA (Gibco) was injected into the bone marrow cavity at one end using a syringe with a 26-gauge needle, and the bone marrow was then collected. After stirring the recovered bone marrow for 30 min, the precipitated bone marrow cells were collected, and cultured in α-minimum essential medium (α-MEM) supplemented with 10% FBS for 24 hrs. Then, non-adherent cells, which are osteoclast pregenitors, were aliquoted onto a culture plate at a density of 2×105 cells per well, and cultured for 8 days in α-MEM supplemented with 20 ng/ml of macrophage-colony stimulating factor (M-CSF, Peprotech, USA), 30 ng/ml RANKL (Peprotech, USA), and 0.3, 1.0 or 3 μM of the compounds of the Examples. Control cells were cultured at the same condition except not adding the compounds of the Examples.
(1-2) Evaluation of Inhibition of Osteoclast (Trap-positive Multinuclear Cell) Formation
After cell culture for 8 days, the adherent cells were washed with PBS and fixed with citrate-acetate-formaldehyde for 5 min. The fixed cells were incubated at 37° C. for 1 hr in acetate buffer (pH 5.0) containing naphthol AS-BI phosphate, fast Garnet GBC solution and 7 mM tartrate buffer (pH 5.0) to conduct TRAP (tartrate-resistant acid phosphatase) staining. After staining, TRAP-positive multinuclear cells having 3 or more nuclei were considered as osteoclast (see, Minkin, C., Calcif. Tissue Int. 34:285-290. 1982), and the inhibitory activities of the compounds of the Examples (0.3, 1.0 and 3.0 μM) on osteoclast formation compared to that of control are shown in Tables 4a and 4b.

As can be seen from Tables 4a and 4b, the α-arylmethoxyacrylate compounds of the present invention have an excellent inhibitory effect on osteoclast formation.
(1-3) Evaluation of Inhibitory Effect on Resorption Activity of Osteoclast
In order to evaluate the effect of the compounds synthesized in the Examples on the resorption activity of the osteoclasts, the differentiated osteoclasts were cultured on a calcium phosphate-coated plate (OAASTM, OCT, Korea) (Choi et al., Eur. J. Immunol. 31:2179-2188, 2001). After finishing culture, the plate was washed with distilled water, and 50 μl/well of 5% sodium hypochlorite was added to the plate. The plate was let alone for 5 min, washed again with distilled water to remove the adherent cells, and dried at room temperature. Then, the area of formed resorption pits was calculated by means of Image Pro Plus software (Media Cybernetics Ver. 3.0). Reduction (%) of the resorption pit area of osteoclasts treated with the compounds of the Examples as compared to that of the control are shown in Table 5.

As can be seen from Table 5, the resorption pit area in the plate treated with one of the compounds of the Examples was remarkably reduced as compared to that of the control, and the resorption activity of osteoclast was almost completely inhibited when more than 0.1 μM of any of the compounds of the Examples was used. This result demonstrates that the α-arylmethoxyacrylate compounds of the present invention have an excellent inhibitory activity against osteoclast.
TEST EXAMPLE 2
Cytotoxicity Test
(2-1) Cytotoxicity Against Osteoclast Pregenitor
In order examine the toxicities of the compounds of the Examples against osteoclast pregenitors, pregenitor cells were aliquotted onto a 96-well microplate at a density of 2×105 cells per well, treated with 2, 4 and 8 μM of the test compounds, respectively, and cultured for 48 hrs in α-MEM supplemented with 20 ng/ml of M-CSF (Peprotech, USA) using 37° C. incubator (5% CO2). At 3 hrs before the culture was finished, 50 μl of MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) solution (50 μg/ml) was added to each well. Upon completion of the cell culture, the supernatant was removed, and the precipitated dye was reacted with 100 μl of isopropanol/0.04 N HCl at room temperature for 30 min to dissolve it. The absorbances of the wells were measured at 550 nm, and the relative absorbance of each well relative to that of the control (set as 100) is shown in Table 6.

TEST EXAMPLE 3
Clinical Test
(3-1) Bone Mineral Density (BMD) Determination of Female Mice Undergone Ovariectomy (Control)
The effect of Compound Nos. 274 and 388 of the present invention on BMD of female mice with osteoporosis induced by ovariectomy was examined as follows.
Specifically, after anesthetizing female mice used as a control by abdominal administration with a mixture of 10 mg/kg body weight of Ketamin HCl (Ketara) and 0.15 ml/kg body weight of 2% Xylazine HCl (Roupun), the lumbar dorsum of each mouse was shaved bilaterally and the exposed skin was prepared for aseptic surgery by a 10% povidone-iodine scrub followed by a 70% alcohol wipe. A 1-cm incision was made in the central region of the abdomen, and the ovaries were identified with caution not to damage the main organs such as the liver and diaphragm. The ovaries were ligated with a suture thread, and then severed. Thereafter, each organ was relocated to its original position, and the incision was closed with a suture thread in an interrupted pattern. After ovariectomy, the mice were injected with 0.088 mg/kg body weight of gentamicin to prevent infection.
To investigate the change in BMD of the mice, bone mineral density was measured before the ovariectomy and every two weeks for 8 weeks after the ovariectomy using a bone mineral densitometer, XCT 540 Research SA (Stratec, Germany). Specifically, BMD measurement was made at a voxel size of 0.1 mm×0.1 mm, threshold values of 280 mg/cm2 for cancellous bone and 500 mg/cm2 for compact bone, and the analysis sites at the proximal tibias were determined by Scout scans (10 mm/sec). BMD was measured at three slices at the determined sites by CT scans (7 mm/sec), and the measurement was performed twice or more at the same site.
(3-2) Determination of BMD in Female Multiparous Mice after Ovariectomy
Multiparous mice each weighing 250 to 350 g were subjected to ovariectomy in accordance with the method of (3-1). From the 2nd day to 12th week after the ovariectomy, the mice were injected subcutaneously once a day with 0.5 and 1 mg/kg body weight/day of Compound Nos. 274 and 388, respectively. Alternatively, the mice were administered orally with 2.5 and 7.5 mg/kg body weight/day of Compound Nos. 274 and 388. BMD was measured before the ovariectomy, and during the period of the 2nd week to 11th week after the ovariectomy.
FIGS. 1a and 1b show the result obtained with the Compound No. 274, wherein the controls not treated with the Compound No. 274 showed a decrease of BMD (subcutaneous injection: 4.0%, oral administration: 6.3%), while the mice treated with the Compound No. 274 showed no decrease of BMD in the case of subcutaneous injection, and little increase of BMD (0.8%) in the case of oral administration.
On the other hand, FIGS. 2a and 2b show the result obtained with the Compound No. 388, wherein the controls not treated with the Compound No. 388 showed sudden decreases of BMD (subcutaneous injection: 15.4%; oral administration: 15.60%) after 8 weeks, while the mice treated with the Compound No. 388 showed sudden decreases in the BMD level (subcutaneous injection: 5.0% at 0.5 mg/kg and 6.7% at 1 mg/kg; oral administration: 10.6% at 2.5 mg/kg and 10.2% at 7.5 mg/kg).
Therefore, it can be concluded that the α-arylmethoxyacrylate compounds of the present invention are effective for preventing and treating osteoporosis.

(4-2) In vivo Pharmacokinetics Using Female Mice
(4-2-1) Administration of Compounds and Serum Separation
Female mice each weighing about 250 g were divided into groups of 5 mice each. The mice were anesthetized with ether, catheterized in their femoral artery and vein, respectively, and administered with 0.5 mg/kg body weight of compounds 234 and 274, and 5 mg/kg body weight of compounds 388, 404 and 415, respectively, via intravenous injection. Alternatively, 15 mg/kg body weight of compound 274 and 10 mg/kg body weight of compound 234 were orally administered to the mice.
At 0, 5, 10, 15 and 30 minutes and 1, 2, 4, 6, 9 and 12 hours after the intravenous injection, or at 0, 10, 20 and 40 minutes and 1, 2, 4, 6, 9 and 12 hours after the oral administration, 0.3 ml blood samples were taken from the mice through femoral artery. The blood samples were kept on an ice bath for 30 minutes and centrifuged at 3,000 rpm for 10 minutes to obtain a supernatant (serum). The supernatant samples were stored at −20° C.
(4-2-2) Determination of the Concentration of the Compounds in the Serum
In the following experiment, HPLC-grade methanol and acetonitrile (Merck) and a HPLC system (Shimadzu LC-10AD) were used.
Standard solution: Compounds 234, 274, 388, 404 and 415 were respectively dissolved in methanol to a concentration of 1 mg/ml to obtain stock solutions. The stock solutions were diluted with methanol to obtain standard solutions having concentrations of 40, 20, 10, 2, 1, 0.5, 0.2, 0.05 and 0.02 μg/ml, respectively.
Standard calibration curve: A stand calibration curve was prepared by employing calibration concentrations of 0.002, 0.005, 0.02, 0.05, 0.1, 0.2, 1, 2 and 4 μg/ml.
10 μl each of the standard solutions prepared above was added to 100 μl of normal serum sample and diluted 10 times. 250 μl of acetonitrile was added to the resulting dilution and the mixture was centrifuged for 10 minutes to obtain a supernatant. 300 μl of the supernatant was dried by evaporation under a nitrogen atmosphere and reconstituted by adding 50 μl of methanol. 20 μl of the resulting solution was analyzed by HPLC to prepare a standard calibration curve. HPLC was performed with Shimadzu ODS2 column (4.6×250 mm, 5 μm by employing a mixture of methanol/water (90/10 (v/v)) as the mobile phase at a flow rate of 1.2 ml/min, and measuring the absorbance at 240 nm.
The resulting stand calibration curves exhibited good linearity.
Extraction: 100 μl of the serum sample obtained in (4-2-1) was put into a 1 ml microtube and 10 μl of methanol was added thereto. 250 μl of acetonitrile was added to the microtube and the mixture was centrifuged for 10 minutes to obtain a supernatant. 300 μl of the supernatant was dried by evaporation under a nitrogen atmosphere and reconstituted by adding 50 μl of methanol. 20 μl of the resulting solution was analyzed by the HPLC method as above.
(4-2-3) Determination of Pharmacokinetic Parameters
Average concentrations of the compounds in the serum samples were plotted in a semi-log scale against the time lapsed after the administration, and the pharmacokinetic parameters were determined as a non-compartment open model by employing WinNonlin® program (Pharsight Corporation). Average values for the pharmacokinetic parameters are shown in Table 9.
