作为表观遗传阅读器,溴结构域和末端外结构域 (BET) 家族蛋白与组蛋白中的乙酰化赖氨酸残基结合并募集蛋白质复合物以促进转录起始和延伸。通过小分子抑制剂抑制 BET 溴结构域已成为一种有前途的癌症治疗策略。在这里,我们描述了我们为发现一系列新的 1-(5-(1 H -benzo[ d ]imidazole-2-yl)-2,4-dimethyl-1 H -pyrrol-3-yl)ethan 所做的努力-1-one 衍生物作为 BET 抑制剂。密集的结构修饰导致化合物35f被鉴定为对 BET 家族蛋白具有选择性的最活跃的 BET BRD4 抑制剂。进一步的生物学研究表明,化合物35f通过降低c-Myc等细胞周期和细胞凋亡相关蛋白的表达,使细胞周期停滞在G 0 /G 1期,诱导细胞凋亡。更重要的是,化合物35f在 MV4-11 小鼠异种移植模型中显示出良好的药代动力学特性和抗肿瘤功效,具有可接受的耐受性。这些结果表明,BET
