selective PTP1B inhibitor because no inhibition was showed by 3l at 100 μm against PTP‐MEG2, TCPTP, SHP2, or SHP1. Subsequent kinetic analysis revealed 3l inhibited α‐glucosidase in a reversible and mixed manner. Molecular docking study indicated that hydrogen bonds, van der Waals, charge interactions and Pi‐cation interactions all contributed to affinity between 3l and α‐glucosidase/PTP1B.
已知α-葡萄糖苷酶可催化碳水化合物的消化并将游离葡萄糖释放到消化道中。蛋白酪氨酸磷酸酶1B(PTP1B)参与胰岛素受体的去磷酸化和胰岛素敏感性的调节。因此,靶向α-葡萄糖苷酶和PTP1B的双重拮抗剂可能是2型糖尿病治疗的潜在候选者。在这项工作中,三个系列新颖的ñ -芳基- ω - (benzoazol -2-基)-sulfanylalkanamides合成并测定其分别α葡糖苷酶和PTP1B抑制活性。化合物3升,表现出最有效的α葡萄糖苷酶抑制活性(IC 50 = 10.96μ米(3升),IC 50 = 51.32μ米(阿卡波糖),IC 50 = 18.22μ米(乌索酸))和有效PTP1B的抑制活性(IC 50 = 13.46μ米(3升),IC 50 = 14.50μ米(乌索酸)),被认定为一种新型的α-葡萄糖苷酶和PTP1B双重抑制剂。此外,3升是一种高选择性PTP1B抑制剂,因为没
