find potent α-glucosidase inhibitors, thirty-one β-carboline derivatives containing piperazine moieties (6a∼6u, 7a∼7j) were synthesized and evaluated their α-glucosidase inhibitory activity. Most β-carboline derivatives showed potential α-glucosidase inhibitory activity, especially, compound 7c presented obvious α-glucosidase inhibitory activity (IC50: 8.9 ± 0.2 μM), ∼ 69 folds stronger than acarbose (IC50:
α-葡萄糖苷酶是糖尿病的重要治疗靶点。为了寻找有效的 α-葡萄糖苷酶抑制剂,合成了31 个含有哌嗪部分的 β-咔啉衍生物 ( 6a∼6u, 7a∼7j ) 并评估了它们的 α-葡萄糖苷酶抑制活性。大多数β-咔啉衍生物表现出潜在的α-葡萄糖苷酶抑制活性,尤其是化合物7c表现出明显的α-葡萄糖苷酶抑制活性(IC 50:8.9 ± 0.2 μM),比阿卡波糖(IC 50:610.7 ± 0.1 μM)强约69倍。抑制机制和动力学解释了化合物7c是一种可逆的混合型抑制剂。采用 CD 光谱、3D 荧光和分子对接揭示7c的机制抗α-葡萄糖苷酶。细胞毒性测定确定了7c的低细胞毒性。
