20090054352BENZENE DERIVATIVE OR SALT THEREOF - Problem: To provide compounds which have an anticoagulation effect based on their ability to inhibit the activated blood coagulation factor X and are useful as coagulation inhibitors or agents for prevention or treatment for diseases caused by thrombi or emboli.02-26-2009
20090137498SUBSTITUTED BENZENE DERIVATIVES OR SALTS THEREOF - There are provided compounds having an anticoagulant action on the basis of inhibition of activated blood coagulation factor X and being useful as anticoagulants or preventive/therapeutic agents for diseases induced by thrombosis or embolism. Effective ingredients are the compounds such as 4′-bromo-2′-[(5-chloro-2-pyridyl)carbamoyl]-6′-β-D-galactopyranosyloxy-1-isopropylpiperidine-4-carboxanilide, 2′-(2-acetamido-2-deoxy-β-D-glucopyranosyloxy)-4′-bromo-6′-[(5-chloro-2-pyridyl)carbamoyl]-1-isopropylpiperidine-4-carboxanilide, etc. or salts thereof.05-28-2009
20090197834QUINOLONE DERIVATIVE OR PHARMACEUTICALLY ACCEPTABLE SALT THEREOF - [Problem] To provide a compound having excellent platelet aggregation inhibitory activity.08-06-2009
20100179137PYRIDONE COMPOUND - [Solving Means] The present inventors have conducted extensive studies on an EP4 receptor agonist, and as a result, found that a novel pyridone compound characterized in that the 1-position in the pyridone ring is substituted with a group having an acidic group such as a carboxyl group and the 6-position is bonded with an aromatic ring group via lower alkyl, lower alkylene, ether, or thioether, has an excellent EP4 receptor agonistic action, thereby completing the present invention. Since the compound of the present invention has an excellent EP4 receptor agonistic action and a blood flow increasing action in the hindlimb of a rat, it is useful as a pharmaceutical, in particular, an agent for treating peripheral arterial occlusive disease.07-15-2010
201002223292-ACYLAMINOTHIAZOLE DERIVATIVE OR SALT THEREOF - A 2-acylaminothiazole derivative or a pharmaceutically acceptable salt thereof having an excellent effect of proliferating human c-mpl-Ba/F3 cells and an activity of increasing platelets based on the effect of promoting the formation of megakaryocytic colonies. A compound or a pharmaceutically acceptable salt thereof useful in treating thrombocytopenia.09-02-2010
201002223612-ACYLAMINOTHIAZOLE DERIVATIVE OR SALT THEREOF - A 2-acylaminothiazole derivative or a pharmaceutically acceptable salt thereof having an excellent effect of proliferating human c-mpl-Ba/F3 cells and an activity of increasing platelets based on the effect of promoting the formation of megakaryocytic colonies. A compound or a pharmaceutically acceptable salt thereof useful in treating thrombocytopenia.09-02-2010
20110082133PYRIDONE COMPOUNDS - [Problems] A useful compound which can be used as a pharmaceutical, in particular, an agent for treating peripheral arterial occlusive disease is provided.04-07-2011
