extra-terminal domain (BET) proteins are epigenetic readers involved in the regulation of gene transcription. Inhibitors of the BET proteins, in particular BRD4, have demonstrated anti-tumour activities and efficacies in clinical trials. Herein, we describe the discovery of potent and selective inhibitors of BRD4, and demonstrate that the lead compound CG13250 is orally bioavailable and efficacious
溴结构域和额外末端结构域 (BET) 蛋白是参与基因转录调控的表观遗传阅读器。BET 蛋白抑制剂,特别是 BRD4,已在临床试验中证明具有抗肿瘤活性和功效。在此,我们描述了 BRD4 强效和选择性抑制剂的发现,并证明先导化合物 CG13250 具有口服生物利用度,并且在小鼠白血病异种移植模型中有效。
