(IC50 = 452.243 ± 54.142 µM). The most promising inhibitors of the two series were compound III-10 (IC50 = 4.120 ± 0.764 μM) and III-24 (IC50 = 0.645 ± 0.052 μM), respectively. Kinetic study and molecular docking simulation revealed that compound III-10 (Ki = 2.04 ± 0.72 μM) is a competitive inhibitor and III-24 (Ki = 0.44 ± 0.53 μM) is a noncompetitive inhibitor against α-glucosidase. Significantly, these
α-葡萄糖苷酶参与碳水化合物水解成葡萄糖并直接介导血糖升高,是 2 型糖尿病的重要治疗靶点。在这项工作中,合成了含有 1,3-噻唑-2-氨基或 1,3-噻唑-2-硫醇部分 ( III-01 ∼ III-30 ) 的 2,5-二取代呋喃衍生物,并筛选了它们对α-葡萄糖苷酶。α-葡萄糖苷酶抑制测定表明,所有化合物的 IC 50都在 0.645–94.033 μM 范围内,比标准抑制剂阿卡波糖 (IC 50 = 452.243 ± 54.142 μM) 更有效。这两个系列中最有希望的抑制剂是化合物III-10 (IC50 = 4.120 ± 0.764 μM)和III-24(IC 50 = 0.645 ± 0.052 μM)。动力学研究和分子对接模拟表明,化合物III-10 (Ki = 2.04 ± 0.72 μM) 是一种竞争性抑制剂,而III-24 (Ki = 0.44 ± 0.53
