α-Glucosidase inhibitors, which can inhibit the digestion of carbohydrates into glucose, are one of important groups of anti-type 2 diabetic drugs. In the present study, we report our effort on the discovery and optimization of α-glucosidase inhibitors with tetrahydrobenzo[b]thiophen-2-yl)urea core. Screening of an in-house library revealed a moderated α-glucosidase inhibitors, 5a, and then the following
α-葡萄糖苷酶抑制剂是一类重要的抗2型糖尿病药物,可抑制碳水化合物消化为葡萄糖。在本研究中,我们报告了我们在发现和优化具有四氢苯并[ b ]噻吩-2-基)脲核心的α-葡萄糖苷酶抑制剂方面的努力。内部文库的筛选揭示了一种缓和的 α-葡萄糖苷酶抑制剂,5a,然后进行以下结构优化以获得更有效的衍生物。与亲本化合物5a (IC 50为 26.71 ± 1.80 μM) 和阳性对照阿卡波糖 (IC 50为 258.53 ± 1.27 μM)相比,大多数这些衍生物对 α-葡萄糖苷酶的抑制活性增加。其中,化合物8r (IC 50 = 0.59 ± 0.02 μM) 和8s (IC 50 = 0.65 ± 0.03 μM) 是最有效的抑制剂,并且表现出优于 α-淀粉酶的选择性。荧光猝灭实验证实了两种化合物与α-葡萄糖苷酶的直接结合。动力学研究表明,这些化合物是非竞争性抑制剂,这与分子对接结果一致,即化
