Abstract: (R)-2-(2-aminothiazol-4-yl)-4?-[2-[(2-hydroxy-2-phenylethyl)amino]ethyl]acetic acid anilide or its salt shows a potent bladder relaxation effect in “isolated rat bladder smooth muscle relaxation test”, dose-dependently lowers the contraction frequency of rhythmic bladder contractions in “rat rhythmic bladder contraction measurement test” and, moreover, prolongs the urination intervals in “urination functions measurement test on cyclophosphamide-induced overactive bladder model rat”. Owing to these effects, the above compound is useful as a remedy for overactive bladder.

Abstract: To provide novel crystals useful as an ingredient for the production of a diabetes remedy. The invention is concerned with ?-form crystal and ?-form crystal of (R)-2-(2-aminothiazol-4-yl)-4?-[2-[(2-hydroxy-2-phenylethyl)amino]ethyl]acetanilide. The ?-form crystal does not exhibit hygroscopicity and has stability such that it can be used as a medicine, and is useful for mass synthesis in the industrial production. The ?-form crystal does not relatively exhibit hygroscopicity and is also useful as a production intermediate of the ?-form crystal.

Abstract: The present invention provides a pharmaceutical composition useful as a therapeutic agent for fatty liver disease. A pharmaceutical composition, which comprises (1S)-1,5-anhydro-1-[5-(azulen-2-ylmethyl)-2-hydroxyphenyl]-D-glucitol or a pharmaceutically acceptable salt thereof, (1S)-1,5-anhydro-1-[3-(1-benzothiophen-2-ylmethyl)-4-fluorophenyl]-D-glucitol or a pharmaceutically acceptable salt thereof, or alternatively, (1S)-1,5-anhydro-1-[4-chloro-3-(4-ethoxybenzyl)phenyl]-D-glucitol or a pharmaceutically acceptable salt thereof, more specifically such a pharmaceutical composition for treating fatty liver disease, such as nonalcoholic fatty liver disease in one embodiment, or nonalcoholic simple fatty liver and/or nonalcoholic steatohepatitis in another embodiment.
