It is intended to provide a remedy or a preventive for hyperuricemia, gout, inflammatory bowel disease, diabetic nephropathy, diabetic retinitis and so on which has a non-nucleic acid structure and exerts an excellent xanthine oxidase inhibitory effect and a uric acid level-lowering effect. It has been confirmed that a novel triarylcarboxlic acid derivative, which is characterized by having a carboxyl-substituted heteroaryl group and an aromatic ring group such as a phenyl group attached in para-position on a benzene ring and further carrying a cyano group on the same benzene ring, has a potent xanthine oxidase inhibitory effect and a uric acid level-lowering effect. Thus, it is found out that this compound is appropriately usable as a remedy or a preventive for hyperuricemia, gout, inflammatory bowel disease, diabetic nephropathy, diabetic retinitis and so on.

La présente invention concerne un composé préventif ou curatif de l'hyperuricémie, de la goutte, des infections inflammatoires du tube digestif, de la néphropathie diabétique, de la rétinite diabétique et d'autres maladies, ledit composé n'ayant pas une structure d'acide nucléique et exerçant des effets excellents d'inhibition de la xanthine-oxydase et d'abaissement du taux d'acide urique. Il a été confirmé qu'un dérivé innovant de l'acide triarylcarboxylique, caractérisé par la présence d'un groupe hétéroaryle à substitution carboxyle et d'un groupe à cycle aromatique tel qu'un groupe phényle lié en position para sur un cycle benzénique et portant en outre un groupe cyano sur le même cycle benzénique, présente de puissants effets d'inhibition de la xanthine-oxydase et d'abaissement du taux d'acide urique. Il a donc été découvert que ce composé peut être utilisé de manière appropriée pour la prévention ou le traitement de l'hyperuricémie, de la goutte, des infections inflammatoires du tube digestif, de la néphropathie diabétique, de la rétinite diabétique et d'autres maladies.
