series of 6-hydroxyaurones and their analogues have been synthesized and evaluated for their in vitro α-glucosidase inhibitory and glucose consumption-promoting activity. These compounds exhibited varying degrees of α-glucosidase inhibitory activity, 11 of them showing higher potency than that of the control standard acarbose (IC50 = 50.30 μM). Surprisingly, analogues devoid of a substituent at C-2 but
已经合成了一系列6-羟基金龙及其类似物,并对其体外α-葡萄糖苷酶抑制和促进葡萄糖消耗的活性进行了评估。这些化合物表现出不同程度的α-葡萄糖苷酶抑制活性,其中11种化合物的药效高于对照标准阿卡波糖(IC 50 = 50.30μM)。令人惊讶地,发现在C-2处没有取代基但在C-5处具有芳基的类似物是高活性的(例如7f,IC 50 =9.88μM)。对接分析证实了这些发现。化合物7f的动力学分析,这项研究中最有效的α-葡萄糖苷酶抑制剂表明,它以不可逆和混合竞争的方式抑制α-葡萄糖苷酶。另外,化合物7f和10c在1μM下表现出显着的促进葡萄糖消耗的活性。
