Series of novel analogs, which were primarily modified on its lactone moiety, was synthesized based on Andrographolide (1), a natural product sesquiterpene inhibitor of α-glucosidase. Among new analogs, 14-deoxy-11,12-didehydro-15-(4-ethoxybenzylidene)andrographolide (3h) was determined to have the greatest potential of α-glucosidase inhibitor through the calculation of IC50 value of 160 ± 5.1 μM,
基于穿心莲内酯(1),一种天然产物倍半萜烯α-葡萄糖苷酶抑制剂,合成了一系列主要在其内酯部分上进行了修饰的新型类似物。在新的类似物中,通过计算160±5.1μM的IC 50值,可以确定14-脱氧11,12-二氢15-(4-乙氧基苄叉基)和穿心莲内酯(3h)具有最大的α-葡萄糖苷酶抑制剂潜力,与阿卡波糖的临床剂量相比有显着改善,后者的IC 50值为390±8.1μM。此外,14-脱氧-11,12-二氢-3,19-(2'-羟基亚苄基)-15-(2-羟基亚苄基)穿心莲内酯(7),在C(3)和C(19)处含有1,3-二恶烷部分的14-脱氧-11,12-二氢-穿心莲内酯的15-亚苄基衍生物也显示出良好的抑制作用,IC 50 260±13μM。这些结果是随后优化抗糖尿病药物的有希望的途径。
