A novel series of substituted N-(4-(2-(4-benzylpiperazin-1-yl)ethoxy)phenyl)-N-methylquinazolin-4-amines were synthesized and evaluated for their in vitro antiproliferative activity. Among them, compound 7a exhibited the best potency, with IC50 values of 0.029–0.147 μM against four types of cancer cell lines. In addition, 7a was confirmed that it could arrest the cell cycle at G2/M phase and trigger
合成了一系列新的取代的N-(4-(2-(4-苄基哌嗪-1-基)乙氧基)苯基)-N-甲基喹唑啉-4-胺,并评估了它们的体外抗增殖活性。其中,化合物7a表现出最佳效能,对四种类型的癌细胞系的IC 50值为0.029-0.147μM。另外,证实了7a可以阻止细胞周期处于G 2 / M期并触发细胞凋亡。间接免疫荧光染色显示其抗微管蛋白特性。重要的是,7a显着抑制了HepG2异种移植模型中的肿瘤生长,而没有引起体重的显着降低,这表明7a 是有前途的新型抗癌药。
