methods to compare yields and reaction times. All compounds obtained in this study were investigated for α-glucosidase inhibitor activity. Compounds 6a, 8a, 4b, 5b, 6b and 7b were potent inhibitors with IC50 values ranging from 10.49 to 158.2μM. This has described a new class of α-glucosidase inhibitors. Molecular docking studies were done for all compounds to identify important binding modes responsible
从邻苯二胺和4-硝基邻苯二胺与亚氨基酯盐酸盐一起制备了一系列新的苯并咪唑衍生物。将苯并咪唑中的酸性质子与溴乙酸乙酯交换,然后将乙酯基转化为酰肼基。使用CS2 / KOH的环化反应生成相应的1,3,4-恶二唑衍生物,将其用异硫氰酸苯酯处理后分别生成碳硫酰胺基。作为目标化合物,通过碳硫酰胺基的环化,在碱性条件下获得三唑衍生物,在酸性条件下获得噻二唑衍生物。大多数反应均使用微波和常规方法进行,以比较产率和反应时间。研究了该研究中获得的所有化合物的α-葡萄糖苷酶抑制剂活性。化合物6a,8a,4b,5b,6b和7b是有效的抑制剂,IC50值在10.49至158.2μM之间。这描述了新型的α-葡萄糖苷酶抑制剂。对所有化合物进行了分子对接研究,以鉴定负责抑制α-葡萄糖苷酶活性的重要结合模式。
