inhibitors with antidiabetic activity, twenty-six indole derivatives containing thiazolidine-2,4-dione were synthesized. All compounds presented potential α-glucosidase inhibitory activities with IC50 values ranging from 2.35 ± 0.11 to 24.36 ± 0.79 μM, respectively compared to acarbose (IC50 = 575.02 ± 10.11 μM). Especially, compound IT4 displayed the strongest α-glucosidase inhibitory activity (IC50 = 2
为了开发具有抗糖尿病活性的潜在α-葡萄糖苷酶抑制剂,合成了26种含有噻唑烷-2,4-二酮的吲哚衍生物。与阿卡波糖相比,所有化合物均表现出潜在的 α-葡萄糖苷酶抑制活性,IC 50值范围分别为 2.35 ± 0.11 至 24.36 ± 0.79 μM(IC 50 = 575.02 ± 10.11 μM)。特别是,化合物IT4表现出最强的α-葡萄糖苷酶抑制活性(IC 50 = 2.35 ± 0.11 μM)。通过动力学研究、荧光猝灭、CD光谱、3D荧光光谱和分子对接等研究,阐明了化合物IT4对α-葡萄糖苷酶的抑制机制。体内抗糖尿病实验表明,口服化合物IT4可以抑制糖尿病小鼠的空腹血糖水平,改善其糖耐量和血脂异常。
