found to have the most potent PL inhibitory activity (IC50 = 4.86, 5.73, 5.83, and 5.94 μM respectively), as compared to orlistat (IC50 = 0.86 μM). The most potent analogues 9af and 9ak were found to inhibit PL competitively with an inhibition constant (Ki) of 2.136, 1.648 μM. Furthermore, the docking study confirmed the binding of analogues 9ak and 9af (MolDock score of −161.25, −133.67 kcal mol−1) that
设计、合成了一系列新的吲哚基氧代乙酰胺-喹唑啉酮杂合类似物 ( 9aa–9df ),并评估了它们的体外胰脂肪酶 (PL) 抑制潜力,这可能会导致有效的抗肥胖剂。所有合成的杂合类似物均表现出中等至强效的 PL 抑制活性(IC 50 = 32.51 至 4.86 μM)。在所有类似物中,与奥利司他 (IC 50 = 0.86 μM)相比,发现9ak、9af、9aj和9ah具有最有效的 PL 抑制活性(IC 50 = 4.86、5.73、5.83 和 5.94 μM) . 最有效的类似物9af和发现9ak以 2.136、1.648 μM 的抑制常数 ( K i )竞争性抑制 PL 。此外,对接研究证实了与重要活性位点氨基酸即 Phe 77、Tyr 114、Ser 152、Arg 256 对接相互作用的类似物9ak和9af(MolDock 评分为 -161.25、-133.67 kcal mol -1
