Zeste enhancer homolog 2 (EZH2) is highly expressed in various malignant tumors, which could silence tumor suppressor genes via trimethylation of H3K27. Herein was first reported a novel series of pyrrole-3-carboxamide derivatives carrying a pyridone fragment as EZH2 inhibitors. By combining computational modeling, in vitro cellular assays and further rational structure–activity relationship exploration
Zeste增强子同源物2(EZH2)在各种恶性肿瘤中高表达,可以通过H3K27的三甲基化沉默沉默抑癌基因。本文首先报道了一系列带有吡啶酮片段作为EZH2抑制剂的吡咯-3-羧酰胺衍生物。通过将计算模型,体外细胞分析以及进一步的合理的构效关系探索和优化相结合,化合物DM-01对EZH2具有强大的抑制作用。在蛋白质印迹试验中,发现DM-01具有降低K562细胞中细胞H3K27me3水平的显着能力。同时,我们的数据显示,敲低A549细胞中的EZH2导致细胞对DM-01的敏感性降低在50和100μM下 DM-01还可以以剂量依赖的方式增加DIRAS3的转录表达,这是EZH2下游的一种抑癌剂,表明它有必要进一步研究作为先导化合物。
