20090209576 | PHARMACEUTICAL COMPOSITION CONTAINING CLOPIDOGREL CAMPHORSULFONATE OR POLYMORPHIC FORMS THEREOF - A pharmaceutical composition of the present invention which comprises clopidogrel camphorsulfonate of formula (I) or its polymorphic forms as an active ingredient is useful for treating or preventing a platelet aggregation-associated disease. | 08-20-2009 |
20090326234 | (S)-(-)-Amlodipine Camsylate or Hydrate Thereof And Pharmaceutical Composition Comprising Same - Disclosed is (S)-(−)-amlodipine camsylate or a hydrate thereof having good photostability and high solubility, and a pharmaceutical composition comprising same, which can be efficiently used in treating cardiovascular diseases. | 12-31-2009 |
20100099884 | METHOD OF PREPARING S-(-)-AMLODIPINE OR A SALT THEREOF AND AN INTERMEDIATE USED THEREIN - The present invention provides a novel method for preparing S-(−)-amlodipine having a high optical purity or a salt thereof and an intermediate used therein. | 04-22-2010 |
20100168433 | PROCESS FOR PREPARING BEPOTASTINE AND INTERMEDIATES USED THEREIN - A process for stereospecific preparation of bepotastine of formula (I) and novel intermediates used therein having formulae (II) to (IV) are provided. The inventive process comprises subjecting (RS)-4-[(4-chlorophenyl)(2-pyridyl)methoxy]piperidine to a reaction with a 4-halobutanoic acid l-menthyl ester, halo being chloro, bromo or iodo, in an organic solvent in the presence of a base to produce (RS)-bepotastine l-menthyl ester of formula (II), conducting a reaction of the compound of formula (II) with N-benzyloxycarbonyl L-aspartic acid in an organic solvent to induce selective precipitation of bepotastine l-menthyl ester.N-benzyloxycarbonyl L-aspartate of formula (III), filtering the precipitates formed in step 2) to isolate the compound of formula (III), treating the compound of formula (III) with a base to liberate bepotastine l-menthyl ester of formula (IV), and hydrolyzing the compound of formula (IV) in the presence of a base. The inventive process can provide bepotastine having a high optical purity of not less than 99.5% in a high yield, and thus, is useful in the development of anti-histamines and anti-allergic agents. | 07-01-2010 |
20100179120 | NOVEL AMIDE DERIVATIVE FOR INHIBITING THE GROWTH OF CANCER CELLS - The present invention provides a novel amide derivative and a pharmaceutically acceptable salt thereof which selectively and effectively inhibits the growth of cancer cells induced by the overexpression of an epidermal growth factor receptor and also prevents the development of drug resistance caused by the mutation of EGFR tyrosine kinase, and a pharmaceutical composition comprising same as an active ingredient. | 07-15-2010 |
20100190983 | PROCESS FOR PREPARING VORICONAZOLE - Optically pure voriconazole can be prepared in a high yield by a) subjecting 1-(2,4-difluorophenyl)-2(1H-1,2,4-triazol-1-yl)ethanone to Reformatsky-type coupling reaction with a substituted thiopyrimidine derivative to obtain a desired (2R,3S)/(2S,3R)-enantiomeric pair; b) removing the thiol derivative from the enantiomer to obtain racemic voriconazole; and c) isolating the racemic voriconazole by way of optical resolution using an optically active acid. | 07-29-2010 |
20110178330 | METHOD FOR PREPARING (3S,4S)-4-((R)-2-(BENZYLOXY)TRIDECYL)-3-HEXYL-2-OXETANONE AND NOVEL INTERMEDIATE USED THEREFOR - The present invention relates to a high-yield method for preparing highly pure (3S,4S)-4-((R)-2-(benzyloxy)tridecyl)-3-hexyl-2-oxetanone using a metal salt of (2S,3S,5R)-2-hexyl-3,5-dihydroxyhexadecanoic acid as an intermediate. | 07-21-2011 |
