cardiovascular disorders. Aldose reductase, the rate-limiting enzyme of the polyol pathway, plays a key role in the pathogenesis of diabetic complications. Accordingly, inhibition of this enzyme is emerging as a major therapeutic strategy for the treatment of hyperglycemia-induced cardiovascular pathologies. In this study, we describe a series of 5(6)-substituted benzofuroxane derivatives, 5a–k,m, synthesized
糖尿病是心血管疾病的主要危险因素。醛糖还原酶是多元醇途径的限速酶,在糖尿病并发症的发病机理中起关键作用。因此,对该酶的抑制正在成为治疗高血糖引起的心血管疾病的主要治疗策略。在这项研究中,我们描述了一系列作为醛糖还原酶抑制剂合成的5(6)-取代的苯并呋喃烷衍生物5a-k,m。除了有效抑制目标酶外,5a–k,m还显示出额外的NO供体和抗氧化剂特性,因此成为新型的多功能化合物。苄氧基衍生物5a,是整个系列中最有前途的产品,显示出均衡的多功能特性,包括亚微摩尔ALR2抑制功效(IC 50 = 0.99± 0.02μM ),显着且自发的NO生成特性以及出色的羟自由基清除活性。对新化合物的计算研究澄清了观察到的醛糖还原酶抑制谱,从而使整个系列的结构与活性之间的关系合理化。
