20090048213Prodrug of cinnamide compound - The present invention provides a most suitable prodrug of a cinnamide compound. The prodrug is represented by Formula (I)02-19-2009
20090048448SALTS OF CYNNAMIDE COMPOUND OR SOLVATES THEREOF - The invention provides crystals of dihydrochloride monohydrate of the compound of the following formula having an Aβ production inhibiting effect which crystals are characterized by exhibiting a diffraction peak at an angle of diffraction (2θ±0.2°) of 10.9° in powder X-ray diffractometry. Further, the invention also provides the compound in the form of various salts, crystal forms and amorphous forms which are suitable for the development of drugs.02-19-2009
20090062529MULTI-CYCLIC COMPOUNDS - A compound represented by the formula (I):03-05-2009
20090181945TWO CYCLIC CINNAMIDE COMPOUND - The present invention relates to a novel two cyclic cinnamide compound and a pharmaceutical agent comprising the compound as an active ingredient. The two cyclic cinnamide compound represented by the general formula (I):07-16-2009
20090203697HETEROCYCLIC TYPE CINNAMIDE DERIVATIVE - Disclosed is a compound represented by the formula (I) below or a pharmacologically acceptable salt thereof. Also disclosed is a use of the compound or salt as a pharmaceutical product.08-13-2009
20090203916Amorphous object of cinnamide compound - An amorphous object of (3E)-1-[l(s)-1-(4-fluorophenyl)ethyl]-3-[3-methoxy-4-(4methyl-1H-imidazol-1-yl)benzylidene]piperidine-2-one, which is represented by the formula (1) and has Aβ-production inhibitory activity.
