A quinoline-3-acetic acid derivative represented by general formula (I) or a medicinally acceptable salt thereof, wherein R¹, R² and R³ may be the same or different from one another and each represents hydrogen or halogen; R⁴ represents hydrogen, halogen or (un)substituted lower alkyl: R⁵ represents optionally esterified carboxyl; and the broken line represents an optional presence of a double bond. The compound (I) and the salt have an aldose reductase inhibitor activity against mammals including man and are excellent in safety, and hence are useful as the drug for the therapeutic treatment of the complications of diabetes, such as faulty union of corneal injury, cataract, neurosis, retinopathy and nephropathy, in particular, cataract and neurosis.
通式(I)代表的喹啉-3-乙酸衍生物或其药用盐,其中 R¹、R² 和 R³ 可以相同或不同,各自代表氢或卤素;R⁴ 代表氢、卤素或(未)取代的低级烷基:R⁵ 代表任选酯化的羧基;断线代表任选存在的双键。化合物(I)和盐对哺乳动物(包括人类)具有醛糖还原酶抑制剂活性,且安全性极佳,因此可作为治疗糖尿病并发症(如角膜损伤、白内障、神经官能症、视网膜病变和肾病,尤其是白内障和神经官能症)的药物。
