A series of novel β-carboline 1,3,4-oxadiazole derivatives were designed and synthesized, and the in vitro cytotoxic activity against Sf9 cells and growth inhibitory activity against Spodoptera litura were evaluated. Bioassay results showed that most of these compounds exhibited excellent in vitro cytotoxic activity. Especially, compound 37 displayed the best efficacy in vitro (IC50 = 3.93 μM), and
设计并合成了一系列新型β-咔啉1,3,4-恶二唑衍生物,并评估了其体外对Sf9细胞的细胞毒活性和对斜纹夜蛾的生长抑制活性。生物测定结果表明,这些化合物中的大多数表现出优异的体外细胞毒活性。特别是,化合物 37 在体外表现出最佳功效(IC50 = 3.93 μM),并且比喜树碱(CPT)(IC50 = 18.95 μM)强五倍。此外,化合物 5 和 37 可以诱导细胞凋亡和细胞周期停滞并刺激 Sf9 细胞中的 Sf-caspase-1 活化。体内生物测定还表明,化合物5和37可以显着抑制斜纹夜蛾幼虫的生长,降低幼虫和蛹的重量。根据这些生物测定结果,
