Compounds 1-9 were found to be known, while compounds 10-15 were found to be new. However, to the best of our knowledge we are reporting α-glucosidase inhibitory activity of these bezamide derivatives of thiourea for the first time. Compounds 1, 3, 6-8, 10-14 were found to be potent inhibitors of α-glucosidase within IC50 range of 20.44-333.41 µM, in comparison to the standard inhibitor, acarbose (IC50=875
基于苯甲酰胺的结构类似物1 - 15合成,并评价首次体外α葡萄糖苷酶抑制活性。发现化合物1-9是已知的,而发现化合物10-15是新的。然而,据我们所知,我们首次报告了这些硫脲苯甲酰胺衍生物的 α-葡萄糖苷酶抑制活性。化合物1,3,6 - 8,10-14被认为是α葡糖苷酶的强效抑制剂内IC 50范围20.44-333.41μM的,相比于标准抑制剂,阿卡波糖(IC 50=875.75±2.08 µM)。酶抑制的模式是基于动力学研究确定的,动力学研究表明化合物8和10分别是 α-葡萄糖苷酶的非竞争性和竞争性抑制剂。还评估了这些化合物的 DPPH 自由基清除活性和对 3T3 小鼠成纤维细胞系的细胞毒性。所有合成的化合物都显示出显着至中等的 DPPH 自由基清除活性,并且似乎没有细胞毒性,但化合物9显示出对 3T3 正常小鼠成纤维细胞系的细胞毒性。还提供了代表性化合物的单晶 X 射线和 Hirshfeld
