antiproliferative agent against HCT-116, RKO, A2780 and Hela cell lines with an IC50 value of 2.56, 3.67, 3.46 and 2.71 μM, respectively. The antitumor efficacy of the representative compound 11x in mice was also evaluated, and the results showed that compound 11x effectively inhibited tumor growth and decreased tumor weight in animal models. Further investigation on mechanism of action indicated that
设计,合成和评估了一系列新的喹啉衍生物的抗增殖活性。结果表明,化合物11p,11s,11v,11x和11y表现出有效的抗增殖活性,对7种人类肿瘤细胞系和N-(3-甲氧基苯基)-7-(3-苯基丙氧基)的IC 50值低于10μM。发现喹啉-4-胺11x是针对HCT-116,RKO,A2780和Hela细胞系的最有效抗增殖剂,IC 50值分别为2.56、3.67、3.46和2.71μM。代表性化合物11x的抗肿瘤功效还评估了小鼠体内的肿瘤,结果表明化合物11x在动物模型中有效抑制了肿瘤的生长并减轻了肿瘤的重量。进一步的作用机理研究表明,化合物11x可以通过ATG5依赖性自噬途径抑制结直肠癌的生长。因此,这些喹啉衍生物是一类新的分子,具有被开发为新的抗肿瘤药物的潜力。
