Abstract:
PURPOSE: Provided are 4-((4-thiazolyl)phenoxy)alkoxy-benzamidine derivatives(DW1350 and DW1352) acting as leukotriene-B4 receptor antagonistic action. The compounds exhibit an excellent inhibition effect on a differentiation, formation, fusion process and bone absorption function of osteoclast cells, therefore they can be effectively used as an prophylaxis and treatment of osteoporosis. CONSTITUTION: The agent for prophylaxis and treatment of osteoporosis contains an effective amount of 4-((4-thiazolyl)phenoxy)alkoxy-benzamidine derivative of formula(1) or a salt thereof. In formula, R is H or OH. The agent is excellent in an inhibition of osteoclast cells as compared to any compound such as DW1349 and DW1351 having structural similarity as well as HS-1141 and CGS-25019C and has increased efficacy in increasing the activity of osteoblast cells.
Abstract:
PURPOSE: Provided is a 3-amido-1,2-benzoisoxazole derivative or a pharmaceutically acceptable addition salt thereof which has improved bioavailability by increasing the aqueous solubility, shows excellent antagonistic effect on an LTB-4 receptor and prevents and/or treats osteoporosis. CONSTITUTION: The 3-amido-1,2-benzoisoxazole derivative of the formula(1) is prepared by introducing an amino acid residue into the amine group of 3-amido-1,2-benzoisoxazole. In the formula(1), R1 is hydrogen, a hydroxyl group, a linear or branched chain alkyl group with C1-C6, a benzyl group or a 2-methylthioethyl group; R2 is hydrogen or -COC(NH2)R3, and R3 is hydrogen, a hydroxyl group, a linear or branched chain alkyl group with C1-C6, a benzyl group, or a 2-methylthioethyl group.
