4-Dichlorophenyl)-2-(2',4'-dioxospiro[fluorene-9,5'-imidazolidine]-3'-yl)acetamide (3e) displayed an 84% reduction in blood glucose level superior to that of repaglinide 66% and showed an IC50 value of 0.37 μM against ALR2 that is superior to that of sorbinil 3.14 µM. Compound (3e) was selective 96 fold towards ALR2 which is closely related to serious diabetic complications. Based on the identification of this
制备了在螺乙内酰脲支架和苯环之间带有乙酰胺连接基的新型非磺酰脲类衍生物,并在体内评估了它们的降血糖活性。确定了他们在体外区分醛还原酶(ALR1)和醛糖还原酶(ALR2)的能力。进行了分子对接和计算机模拟预测研究,以合理化所获得的生物学结果,并预测新化合物的理化性质和药物相似性得分。N-(2,4-二氯苯基)-2-(2',4'-二氧螺并[芴-9,5'-咪唑烷] -3'-基)乙酰胺(3e)的血糖水平降低了84%达到瑞格列奈的66%,对ALR2的IC50值为0.37μM,优于山梨醇3.14 µM。化合物(3e)对ALR2的选择性是96倍,这与严重的糖尿病并发症密切相关。基于此候选药物的鉴定,可以设计新一代安全有效的抗糖尿病药。
