In the present study, a novel generation of selective aldose reductase ALR2 inhibitors with significant hypoglycemic activities was designed and modulated based on rhodanine scaffold joined to an acetamide linker in between two lipophilic moieties. The synthesis of the novel compounds was accomplished throughout simple chemical pathways. Molecular docking was performed on B-cell membrane protein SUR1
在本研究中,设计并调节了具有显着降血糖活性的新一代选择性醛糖还原酶 ALR2 抑制剂,其基础是在两个亲脂性部分之间连接到乙酰胺接头的罗丹宁支架。新化合物的合成是通过简单的化学途径完成的。在B细胞膜蛋白 SUR1、醛还原酶 ALR1 和醛糖还原酶 ALR2 活性位点上进行分子对接。化合物10B、11B、12B、15C、16C、26F和27F显示出最高的降血糖活性,血糖水平分别降低了 80.7、85.2、87、82.3、83.5、81.4 和 85.3%。它们比标准降血糖药瑞格列奈更有效,血糖水平降低 65.4%。IC 50 0.29 和 0.35 µM 的化合物12B和15C比 IC 50 0.40 µM的标准 ALR2 抑制剂依帕司他更有效。它们对 ALR2 的选择性分别超过 ALR1 134 和 116 倍。分子对接研究与体外和体内结果相匹配,以阐明化合物12B和15C的双重活性 作为 ALR2
