influence of the cytotoxic compound 7f on the cell cycle distribution was assessed on the DU145 cell line, exhibiting a cell cycle arrest at the G2/M phase (hallmark of tubulin polymerization) and next inhibited tubulin polymerization with IC50 0.40 μM. Furthermore, the treatment with compound 7f caused collapse of mitochondrial membrane potential and elevated intracellular superoxide ROS levels in DU145 cells
合成了一系列C 5系链的吲哚基-3-乙醛酰胺衍生物,并评估了它们对DU145(前列腺),PC-3(前列腺),A549(肺)和HCT-15(结肠)癌细胞系的体外细胞毒活性。通过使用3-(4,5-二甲基噻唑-2-基)-2,5-二苯基四唑溴化物(MTT)分析。在所有合成的化合物中,化合物7f 对DU145癌细胞系的IC 50为140 nM。用7f处理DU145细胞导致细胞迁移能力的抑制。此外,如the啶橙/溴化乙锭(AO / EB),DAPI,膜联蛋白V-FITC /碘化丙啶染色的详细研究表明,化合物7f诱导DU145细胞凋亡。在DU145细胞系上评估了细胞毒性化合物7f对细胞周期分布的影响,显示了在G2 / M期的细胞周期停滞(微管蛋白聚合的标志),然后用IC 50 0.40μM抑制了微管蛋白聚合。此外,用化合物7f处理导致DU145细胞中的线粒体膜电位崩溃和细胞内超氧化物ROS水平升高。进行
