antiproliferative activity with IC50 in the range of 0.19-0.51 μM. The compound inhibited tubulin polymerization and disrupted the microtubule network, leading to G2/M phase arrest. Furthermore, compound 12 induced ROS production and malfunction of mitochondrial membrane potential. Compound 12 led to cancer cells apoptosis in a dose-dependent manner. Western blot analysis showed that compound 12 induced up-regulation
合成了一系列新颖的喹喔啉衍生物,并评估了它们在三种人类癌细胞系中的抗增殖活性。化合物12表现出最有效的抗增殖活性,IC50在0.19-0.51μM的范围内。该化合物抑制微管蛋白聚合并破坏微管网络,导致G2 / M期停滞。此外,化合物12诱导了ROS的产生和线粒体膜电位的故障。化合物12以剂量依赖性方式导致癌细胞凋亡。蛋白质印迹分析表明,化合物12诱导p21的上调并影响细胞周期相关蛋白的表达。结合模式也通过分子对接来探测。
