In an effort to design and synthesize a new class of α-glucosidase inhibitor, we synthesized benzothiazole hybrid having benzohydrazide moiety (5). Compound 5 was reacted with various substituted aryl aldehyde to generate a small library of compounds 6–35. Synthesis of compounds was confirmed by the spectral information. These compounds were screened for their α-glucosidase activity. They showed a
为了设计和合成新型的α-葡萄糖苷酶抑制剂,我们合成了具有苯并酰肼部分(5)的苯并噻唑杂化物。化合物5与各种取代的芳基醛反应,生成化合物的小库6 - 35。通过光谱信息证实了化合物的合成。筛选这些化合物的α-葡萄糖苷酶活性。他们显示出不同程度的α-葡萄糖苷酶抑制作用,IC 50值在5.31至53.34μM之间。化合物6,7,9 - 16,19,21 - 30,32 - 35显示了优良的活性相对于标准阿卡波糖(IC 50 = 906±6.3微米)。这已经确定了新的一类α-葡萄糖苷酶抑制剂。预测的理化性质表明大多数化合物符合Lipinski的5规则(RO5),因此适用于大多数此类化合物。使用混合B3LYP密度泛函理论(DFT)进行能量分析,使用6-311 + G(d,p)基集对所有合成化合物的3D结构进行最小化,然后进行分子对接,探索它们与人肠C-和N的相互作用α的末端结构域-葡糖苷酶。所有化
