investigation of the mechanism of action of this class of compounds demonstrated that the representative compound 10g triggered p53/Bax-dependent colorectal cancer cell apoptosis by activating p53 transcriptional activity. Moreover, the results showed that compound 10g effectively inhibited tumor growth in a colorectal cancer xenograft model in nude mice. Thus, these quinoline derivatives might serve as candidates
设计,合成和评估了一系列新的喹啉衍生物作为潜在的抗肿瘤药物。结果表明,大多数化合物显示出有效的抗增殖活性,并且发现7-(4-氟苄氧基)N-(2-(二甲基氨基)-乙基)喹啉-4-胺10g是对人肿瘤细胞系最有效的抗增殖剂。带有IC 50值小于1.0μM。初步的结构-活性关系分析表明:(1)7位大而庞大的烷氧基取代基可能是抗增殖活性的有益药效基团;(2)第4位的氨基侧链取代基促进了这类化合物的抗增殖活性;(3)烷基氨基侧链部分的长度影响抗增殖能力,其中两个CH 2单元是最有利的。对这类化合物的作用机理的进一步研究表明,代表性化合物10g通过激活p53转录活性来触发p53 / Bax依赖性结直肠癌细胞凋亡。此外,结果表明,化合物10g有效地抑制了裸鼠结肠直肠癌异种移植模型中的肿瘤生长。因此,这些喹啉衍生物可以作为开发新的抗肿瘤药物的候选者。
