The present invention relates to an inhibitor for the production of 3-deoxyglucosone (3-DG) which contains at least one of parabanic acid derivatives represented by the following formula (I) or pharmaceutically acceptable salts thereof as an effective ingredient
wherein R is hydrogen or lower alkyl; X is hydrogen, alkyl, cycloalkyl, lower alkylcycloalkyl, phenyl or phenylalkyl which is optionally substituted with lower alkyl, lower alkoxy, nitro and/or halogen; and n is an integer of from 1 to 4.
The compound of the present invention has an action of inhibiting the production of 3-DG which is a highly active intermediate and participates in a protein crosslinked formation in Maillard reaction and, therefore, said compound is useful in the treatment and the prevention of various diseases induced by deposition into tissues or sclerosis or denaturation of crosslinked protein, similar diseases induced by aging and diabetic complications.
本发明涉及一种生产 3-脱氧葡萄糖苷(3-DG)的抑制剂,它含有下式(I)所代表的至少一种对位苯甲酸衍生物或其药学上可接受的盐作为有效成分
其中 R 是氢或低级烷基;X 是氢、烷基、环烷基、低级烷基环烷基、苯基或苯基烷基,可任选被低级烷基、低级烷氧基、硝基和/或卤素取代;n 是 1 至 4 的整数。
本发明的化合物具有抑制 3-DG 生成的作用,3-DG 是一种高活性的中间体,参与 Maillard 反应中蛋白质交联的形成,因此,本发明的化合物可用于治疗和预防由组织沉积或硬化或交联蛋白质变性引起的各种疾病、由衰老和糖尿病并发症引起的类似疾病。
