A series of novel 4-anilinoquinoline derivatives were synthesized and evaluated for their antiproliferative activities. Among them, 14h exhibited the most potent cytotoxic activity with IC50 values ranging from 1.5 to 3.9 nM against all tested cancer cell lines, and showed promising efficacy in multidrug resistant cancer cells.

合成了一系列新颖的4-苯胺基喹啉衍生物,并对其抗增殖活性进行了评估。其中,14h对所有测试的癌细胞系表现出最强的细胞毒性活性,IC 50值在1.5至3.9 nM之间,并且在多药耐药癌细胞中显示出有希望的功效。流式细胞仪分析,免疫荧光染色,微管动力学分析和EBI竞争分析通过结合秋水仙碱位点,发现14h是一种新型的微管蛋白解聚剂。重要的是,HCT116异种移植模型14h的体内功效评估显示出有效的抗肿瘤活性,而体重却没有显着下降。所有结果表明14h 可能是治疗癌症的有前途的候选人。
