A series of quinoline derivatives was synthesized and biologically evaluated as Enhancer of Zeste Homologue 2 (EZH2) inhibitors. Structure-activity relationship (SAR) studies led to the discovery of 5-methoxy-2-(4-methyl-1,4-diazepan-1-yl)-N-(1-methylpiperidin-4-yl)quinolin-4-amine (5k), which displayed an IC50 value of 1.2 μM against EZH2, decreased global H3K27me3 level in cells and also showed good anti-viability activities against two tumor cell lines. Due to the low molecular weight and the fact that no quinoline derivative has been reported as an EZH2 inhibitor, this compound could serve as a lead compound for further optimization.
一系列喹啉衍生物被合成并生物学评估为增强型Zeste同源物2(EZH2)抑制剂。结构-活性关系(SAR)研究表明,发现了一种化合物5-甲氧基-2-(4-甲基-1,4-二氮杂环庚烷-1-基)-N-(1-甲基哌啶-4-基)喹啉-4-胺(5k),其对EZH2的IC50值为1.2 μM,能降低细胞内全局H3K27me3水平,并显示出对两种肿瘤细胞株的良好抗增殖活性。由于其低分子量且迄今未有喹啉衍生物报道作为EZH2抑制剂,该化合物可能作为进一步优化的先导化合物。
