characterized and evaluated for their pancreatic lipase inhibitory activity. Porcine pancreatic lipase (Type II) was used with 4-nitrophenyl butyrate (as substrate) for the in vitro assay. Compound 8f exhibited competitive inhibition against pancreatic lipase with IC50 value of 4.92 µM, comparable to that of the standard drug, orlistat (IC50 = 0.99 µM). Compounds 7a-i and 8a-i were subjected to molecular docking
合成了一系列十八个吲哚乙醛酰胺类似物,表征并评估了它们对胰腺脂肪酶的抑制活性。猪胰脂肪酶(II型)与丁酸4-硝基苯酯(作为底物)一起用于体外测定。化合物8f对胰腺脂肪酶表现出竞争性抑制作用,IC50值为4.92 µM,与标准药物奥利司他(orlistat)相当(IC50 = 0.99 µM)。使化合物7a-i和8a-i分子对接至人PL(PDB ID:1LPB)的活性位点,其中化合物8f的潜在MolDock得分为-153.037 kcal / mol。与胰脂肪酶复合的8f的分子动力学模拟,证实了芳香族取代在通过疏水相互作用稳定配体中的作用(最大观察到的RMSD = 3.5)。
