  An object of the present invention is to provide an agent for treating or preventing digestive ulcer that is effective even to ulcer of small intestine and others, for which gastric acid secretion inhibitors such as proton pump inhibitors are ineffective, and is superior to allopurinol in the efficaciousness and the safety. The pharmaceutical composition of the present invention comprising a non-purine xanthine oxidase inhibitor as the active ingredient is useful as an agent for treating or preventing ulcer that forms in digestive tracts by the attack of gastric acid, pepsin, stress, Helicobacter pylori bacteria, NSAID, etc. In particular, it is useful as an ulcer remedy heretofore unknown in the art as it is effective even for ulcer in small intestine for which gastric/duodenal ulcer remedies that inhibit gastric acid secretion such as proton pump inhibitors are ineffective.

  本发明的目的是提供一种治疗或预防消化性溃疡的药剂，即使是质子泵抑制剂对小肠溃疡等无效的溃疡也能有效治疗或预防，并且在功效和安全性方面优于丙戊酸和乙酰水杨酸等药物。本发明的药物组合物包括非嘌呤黄嘌呤氧化酶抑制剂作为活性成分，可用作治疗或预防由胃酸、胃蛋白酶、压力、幽门螺杆菌、NSAID等侵蚀消化道形成的溃疡的药剂。特别是，它是一种迄今为止在技术上未知的溃疡治疗方法，因为它即使对于质子泵抑制剂等抑制胃酸分泌的胃/十二指肠溃疡治疗方法也非常有效，对于小肠溃疡也非常有效。

  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。
