Abstract: Provided is a triarylcarboxylic acid derivative, or an isomer, a prodrug, a hydrate, a solvate, a polymorph, or a pharmaceutically acceptable salt thereof, represented by the following general formula (I): wherein A is an optionally substituted aryl or heteroaryl, and B is an optionally substituted monocyclic heteroaryl; and a pharmaceutical composition comprising the same and a pharmaceutically acceptable carrier. The triarylcarboxylic acid derivative (I) exhibits potent xanthine oxidase inhibiting action and is therefore useful as a therapeutic agent for preventing or treating hyperuricemia, gout, inflammatory bowel disease, diabetic nephropathy and diabetic retinopathy.

Abstract: There is provided a pharmaceutical drug, particularly a novel compound useful for prophylaxis or a therapeutic treatment of various diseases involving infections with viruses of the herpesvirus family, specifically various herpesvirus infections such as varicella (chicken pox) via varicella zoster virus, varicella zoster via recurrent infection with latent varicella zoster virus, herpes labialis and herpes encephalitis via HSV-1 and genital herpes via HSV-2 infection. An N-{2-[(4-substituted phenyl)amino]-2-oxoethyl}tetrahydro-2H-thiopyran-4-carboxamide derivative, of which phenyl group is substituted at position 4 with a specific 5- or 6-membered heteroaryl group, and a salt thereof have an effective anti-virus activity, and the oral administration thereof at a low dose enabled the therapeutic treatment of the above diseases.

Abstract: The present invention relates to a 2-phenylthiophene derivative or a salt thereof, wherein the thiophene ring is substituted with a carboxyl group or the like and the benzene ring has an electron-withdrawing group such as a cyano group and an electron-donating group such as a substituted alkoxy group at the same time. Since the compound of the invention has good xanthine oxidase-inhibitory action and uric acid-lowering action and does not have a structure derived from nucleic acid, the compound has advantages of high safety and excellent effects as compared with conventional compounds and is useful as a therapeutic or preventive agent for hyperuricemia, gout, inflammatory bowel diseases, diabetic kidney diseases, diabetic retinopathy, or the like.
