  摘要：

  zeste同源物2（EZH2）的增强子是多梳抑制复合物2（PRC2）的催化亚基，与癌症进展转移和不良预后有关。基于具有低纳摩尔活性的EZH2抑制剂SKLB1049，我们扩展了“尾巴”区域，获得了一系列作为新型EZH2抑制剂的（E）-1,2-二苯乙烯衍生物。SAR探索和初步评估导致发现了有效的新型EZH2抑制剂9b（EZH2WT IC50 = 22.0 nM）。化合物9b抑制WSU-DLCL2和SU-DHL-4细胞系的增殖（IC50分别为1.61 µM和2.34 µM）。生物学评估表明，9b是野生型EZH2的有效抑制剂，并以浓度依赖的方式大大降低了H3K27me3的总体水平。进一步的研究表明9b可以显着诱导SU-DHL-4细胞凋亡。这些发现表明9b将是用于进一步优化和评估的有吸引力的先导化合物。
