    • A preparation method of porous beta-tricalcium phosphate (TCP) granules is provided to use dispersion medium to form granules and to facilitate gelification and to produce bio compatible eta-tricalcium phosphate (TCP) granules. The preparation method of porous beta-tricalcium phosphate (TCP) granules includes the steps of; preparing a gelatin solution; preparing TCP slurry by mixing tricalcium phosphate precursor powder and pore precursor and adding the gelatin solution; forming and gelificating sphere shape granules by adding the mixed TCP slurry to dispersion medium that is being stirred; separating and washing the surfaces of gelificated sphere shape granules with an organic solvent; and removing additives other than TCP by calcinating or sintering the sphere shape granules.

    • A novel quinoline ester derivative is provided to promote the secretion of OPG from osteoblast and inhibit the differentiation of osteoclast, thereby being usefully used as an agent for preventing and treating metabolic bone diseases such as osteoporosis and osteoarthritis. A method for preparing the same is provided to produce the desired product at relatively cheap cost due to be manufactured from a low molecular material which is able to be synthesized easily. A quinoline ester derivative is represented by the formula(1), wherein X is H or halogen; Z is H, halogen, unsubstituted or substituted linear or branched C1-10 alkyl, C5-10 aryl, C2-8 heterocycliyl, C1-10 alkylamine, C1-10 alkenylamine, C5-10 aryl, C1-10 alkylamine, C5-10 cycloalkylamine or C1-10 hydroxyalkylamine; R is phenyl carboxyl substituted by U and Y represented by the formula(2). In the formula(2), U is -O-(CH2)m-V or -CH2-O-(CH2)m-V(wherein m is an integer from 0 to 10; V is H, C5-10 aryl substituted by R1(which is selected from the group consisting of H, halogen, nitro, cyano, C2-8 heteroaryl and C2-8 heterocyclo C1-10 alkyloxy), C2-8 heterocyclyl, C5-10 aryloxy or C5-10 arylamine); and Y is H, halogen, hydroxy, amino, nitro, unsubstituted or substituted linear or branched C1-10 alkyl, C2-8 heterocyclyl, C1-10 alkyl, C5-10 aryl or C2-8 heteroaryl, provided that the heterocyclyl, heteroaryl or heterocycloalkyloxy includes at least one hetero atom. A method for preparing the quinoline ester derivative comprises the steps of: (a) dissolving a compound represented by the formula(3) in a proper solvent to prepare a starting material; and (b) reacting the starting material with at least one compound selected from the group consisting of catechol, alkyl bromide and heterocycle compounds(V-H) to prepare the compound of the formula(1), wherein A is H or C1-10 halogenated alkyl; each R, X, Z and V is same as defined above. An agent for preventing and treating a metabolic bone disease comprises the quinoline derivative as an effective ingredient.
