| 20120136149 | METHOD FOR PREPARING 5-CHLORO-N-(METHYL)THIOPHEN-2-CARBOXAMIDE DERIVATIVE AND INTERMEDIATE USED THEREIN - Disclosed are: a method for preparing a 5-chloro-N-({(5S)-2-oxo-3-[4-(5,6-dihydro-4H-[1,2,4]triazin- | 05-31-2012 |
| 20120108808 | METHOD FOR PREPARING (S)-5-CHLORO-N-((3-(4-(5,6-DIHYDRO-4H-1,2,4-OXADIAZIN-3-YL)PHENYL)-2-OXOO- XAZOLIDIN-5-YL)METHYL)THIOPHENE-2-CARBOXAMIDE DERIVATIVES - Provided is a method for preparing (S)-5-chloro-N-((3-(4-(5,6-dihydro-4H-1,2,4-oxadiazin-3-yl)phenyl)-2-oxooxazolidin-5-yl)methyl)thiophene-2-carboxamide derivatives of Formula (I) which are useful as blood coagulation factor Xa inhibitors, and said method using 1-fluoro-4-nitrobenzen as a starting material. According to the method of the present invention, (S)-5-chloro-N-((3-(4-(5,6-dihydro-4H-1,2,4-oxadiazin-3-yl)phenyl)-2-oxooxazolidin-5-yl)methyl)thiophene-2-carboxamide derivatives of Formula (I) which are useful as blood coagulation factor Xa inhibitors can be prepared in a high purity and a high yield. | 05-03-2012 |
| 20110178293 | Novel Oxazolidinone Derivatives with Cyclic Amidoxime or Cyclic Amidrazone and Pharmaceutical Compositions Thereof - Disclosed is a novel oxazolidinone derivative, particularly a novel oxazolidinone compound with a cyclic amidoxime or cyclic amidrazone group. Also disclosed is a pharmaceutical antibiotic composition including a novel oxazolidinone derivative, a prodrug thereof, a hydrate thereof, a solvate thereof, an isomer thereof or a pharmaceutically acceptable salt thereof as an effective ingredient. Because the novel oxazolidinone derivative, a prodrug thereof, a hydrate thereof, a solvate thereof, an isomer thereof or a pharmaceutically acceptable salt thereof exhibits a wide antibacterial spectrum against resistant bacteria, a low toxicity, and a strong antibacterial activity against Gram-positive and Gram-negative bacteria, it can be usefully used as an antibiotic. | 07-21-2011 |
| 20110112083 | FXA INHIBITORS WITH CYCLIC AMIDOXIME OR CYCLIC AMIDRAZONE AS P4 SUBUNIT, PROCESSES FOR THEIR PREPARATIONS, AND PHARMACEUTICAL COMPOSITIONS AND DERIVATIVES THEREOF - The present invention relates to novel oxazolidinone derivatives with cyclic amidoxime or cyclic amidrazone group, pharmaceutically acceptable salts thereof, methods for preparing the same and pharmaceutical compositions comprising the same. The oxazolidinone derivatives with cyclic amidoxime or cyclic amidrazone group or the pharmaceutically acceptable salts thereof can be effectively used for the treatment of thromboembolism and tumor as an anticoagulant based on the inhibition of factor Xa. | 05-12-2011 |
| 20100184781 | FXA INHIBITORS WITH CYCLIC AMIDINES AS P4 SUBUNIT, PROCESSES FOR THEIR PREPARATIONS, AND PHARMACEUTICAL COMPOSITIONS AND DERIVATIVES THEREOF - The present invention relates to novel oxazolidinone derivatives with cyclic amidines, and prodrugs, hydrates, solvates, isomers and pharmaceutically acceptable salts thereof, and processes for preparing the same, and pharmaceutical compositions comprising the same. The oxazolidinone derivatives with cyclic amidines, and prodrugs, hydrates, solvates, isomers and pharmaceutically acceptable salts thereof can be usefully employed as an anticoagulant for treating thromboembolism and tumors via inhibition of coagulation factor Xa. | 07-22-2010 |
