all compounds (6a-6o) showed α-glucosidase (from S. cerevisiae) inhibitory activity (IC50 = 12.18 ± 0.08 - 79.34 ± 1.30 μM) by comparison with standard acarbose (IC50 = 774.69 ± 11.65 μM). A study on the kinetics of compound 6c showed a competitive mode against α-glucosidase. In addition, the changes in fluorescence intensity, secondary structure, and possible binding sites in the interaction between
本研究通过分子杂交获得了一系列噻唑苯甲酰胺衍生物(6a-6o),并筛选其对α-葡萄糖苷酶活性的抑制研究。结果表明, 与标准阿卡波糖 (IC 50 = 774.69 ± 11.65 μM) 相比,所有化合物 ( 6a-6o ) 均表现出 α-葡萄糖苷酶 (来自酿酒酵母) 抑制活性 (IC 50 = 12.18 ± 0.08 - 79.34 ± 1.30 μM ) 。。化合物6c的动力学研究显示其与 α-葡萄糖苷酶具有竞争模式。此外, 6c之间的相互作用中荧光强度、二级结构和可能的结合位点的变化分别使用荧光光谱法、圆二色性和分子对接研究了α-葡萄糖苷酶。此外,体内实验表明6c可以降低蔗糖负荷实验中血糖水平的升高。此外,化合物6c对人正常HEK 293细胞系具有低细胞毒活性。
