A group of styrylquinolines were synthesized and tested for their anti-proliferative activity. Anti-proliferative activity was evaluated against the human colon carcinoma cell lines that had a normal expression of the p53 protein (HCT116 p53+/+) and mutants with a disabled TP53 gene (HCT116 p53-/-) and against the GM 07492 normal human fibroblast cell line. A SAR study revealed the importance of Cl and OH as substituents in the styryl moiety. Several of the compounds that were tested were found to have a marked anti-proliferative activity that was similar to or better than doxorubicin and were more active against the p53 null than the wild type cells. The cellular localization tests and caspase activity assays suggest a mechanism of action through the mitochondrial pathway of apoptosis in a p53-independent manner. The activity of the styrylquinoline compounds may be associated with their DNA intercalating ability.
一组苯乙烯基喹啉被合成并测试其抗增殖活性。抗增殖活性对人类结肠癌细胞系进行评估,这些细胞系正常表达p53蛋白(HCT116 p53+/+)以及带有失活TP53基因的突变体(HCT116 p53-/-),同时还对GM 07492正常人类成纤维细胞系进行评估。一项SAR研究揭示了氯和羟基作为苯乙烯部分取代基的重要性。测试中的几个化合物被发现具有显著的抗增殖活性,其活性与或优于多柔比星,并且在p53缺失细胞中活性更强于野生型细胞。细胞定位测试和半胱天冬酶活性测定表明其作用机制通过线粒体途径以非p53依赖的方式诱导细胞凋亡。苯乙烯基喹啉化合物的活性可能与其DNA插层能力有关。
