several compounds, the benzothiophene derivative (14a) was found to have potent inhibitory activity against SGLT2 and good selectivity versus SGLT1. Through further optimization of 14a, a novel benzothiophene derivative (14h; ipragliflozin, ASP1941) was discovered as a highly potent and selective SGLT2 inhibitor that reduced blood glucose levels in a dose-dependent manner in diabetic models KK-Ay mice and
合成了一系列具有各种杂芳族化合物的C-葡萄糖苷,并评估了其对SGLT的抑制活性。在筛选了几种化合物后,发现苯并噻吩衍生物(14a)对SGLT2具有有效的抑制活性,并且对SGLT1具有良好的选择性。通过进一步优化14a,发现了一种新型的苯并噻吩衍生物(14h ;伊格列净,ASP1941)是一种高效且选择性的SGLT2抑制剂,可在糖尿病模型KK-A y小鼠和STZ大鼠中以剂量依赖的方式降低血糖水平。
