Abstract:
The present invention relates to a novel benzamidine derivative, a process for the preparation thereof, and a pharmaceutical composition comprising the same. The benzamidine derivative of the present invention effectively inhibits osteoclast differentiation at an extremely low concentration, and greatly increases the trabecular bone volume, and thus it can be advantageously used for the prevention and treatment of osteoporosis.
Abstract:
An N- hydroxy-4- benzamidine 2 ethansulfonic acid salt is provided to show excellent solubility, stability, and bioavailability, as well as a higher initial release rate than 2 methansulfonic acid salt thereof. An N-hydroxy-4-benzamidine 2 ethansulfonic acid salt is represented by a formula(1) and is prepared by reacting N- hydroxy-4-benzamidine and ethanesulfonic acid in an inert solvent. A pharmaceutical composition for preventing and treating osteoporosis, bone fractures, allergic or inflammatory diseases comprises the N- hydroxy-4-benzamidine 2 ethansulfonic acid salt and a pharmaceutically acceptable carrier. An oral formulation for preventing and treating osteoporosis, bone fractures, and allergic inflammatory diseases, comprises the N- hydroxy-4-benzamidine 2 ethansulfonic acid salt along with (a) at least one carbonate selected from the group consisting of alkali metal carbonate, alkali metal bicarbonate and alkaline earth metal carbonate; (b) at least one disintegrant selected from the group consisting of sodium carboxymethyl starch, sodium carmellose, calcium carmellose and sodium croscarmellose; or a combination of (a) and (b).
Abstract:
A composition for preventing and treating osteoporosis comprising terpenoids isolated from Euphorbia kansui or the extracts thereof is provided to inhibit bone absorption of osteoclasts without side effects. The composition for preventing and treating osteoporosis comprises kansuinine A represented by the formula(1) and gamma-euphorbol represented by the formula(2) or the extracts thereof. The kansuinine A represented by the formula(1) and gamma-euphorbol represented by the formula(2) are isolated by extracting and concentrating Euphorbia kansui with methanol, suspending the concentrated extract of Euphorbia kansui in water, and adding nucleic acid into the suspension to separate a nucleic acid layer, adding methylene chloride into a water layer obtained by separating the nucleic acid layer to obtain a methylene chloride fraction, and subjecting the methylene chloride fraction to chromatography.
