A series of styrylquinolines was designed and synthesized based on the four main quinoline scaffolds including oxine, chloroxine and quinolines substituted with a hydroxyl group or chlorine atom at the C4 position. All of the compounds were tested for their anticancer activity on wild-type colon cancer cells (HCT 116) and those with a p53 deletion. Analysis of SAR revealed the importance of electron-withdrawing
基于四个主要的
喹啉骨架设计并合成了一系列的
苯乙烯基
喹啉,这些骨架包括在C4位置被羟基或
氯原子取代的牛,
氯辛和
喹啉。测试了所有化合物对野生型结肠癌细胞(HCT 116)和具有p53缺失的癌细胞的抗癌活性。
SAR分析表明,在
苯乙烯基部分有吸电子取代基,在
喹啉环上具有螯合性能。还在TP53突变的4种癌
细胞系中测试了活性更高的化合物肿瘤抑制
基因。结果表明,
苯乙烯基
喹啉可诱导细胞周期停滞并激活p53非依赖性细胞凋亡。研究了最有前途的化合物的表观作用机理,这些化合物产生了活性氧,并改变了细胞的氧化还原平衡。
