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.
