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.
本发明涉及一种
2-苯基噻吩衍
生物或其盐,其中
噻吩环被羧基或类似物取代,苯环同时具有电子吸引基(如
氰基)和电子供给基(如取代烷氧基)。由于该化合物具有良好的
黄嘌呤氧化酶抑制作用和降
尿酸作用,并且不具有源自核酸的结构,因此与传统化合物相比,该化合物具有高安全性和优异的效果,并可用作治疗或预防高
尿酸血症、痛风、炎症性肠病、糖尿病肾病、糖尿病视网膜病等的药物。
