Recently, selective inhibition of BET BD2 is emerging as a promising strategy for drug discovery. Despite significant progress in this area, systematic studies of selective BET BD2 inhibitors are still few. In this study, we report the discovery of a potent and selective BET BD2 inhibitor BY27 (47). Our high resolution co-crystal structures of 47/BRD2 BD1 and BD2 showed that the triazole group of 47
最近,对BET BD2的选择性抑制正在成为一种有前途的药物发现策略。尽管在该领域取得了重大进展,但选择性BET BD2抑制剂的系统研究仍然很少。在这项研究中,我们报告了一种有效且选择性的BET BD2抑制剂BY27的发现(47)。我们的高分辨率共晶体结构47 / BRD2 BD1和BD2显示,BRD2 BD2中的47,水分子,H433和N429的三唑基建立了水桥H键网络,这是观察到的选择性的原因。用47或OTX015处理的HepG2细胞的DNA微阵列分析表明,BET BD2选择性抑制剂和pan BET抑制剂之间的转录组影响差异。在MV4-11小鼠异种移植模型中,47在大剂量时可引起67%的肿瘤生长抑制,且毒性比pan BET抑制剂1低。我们得出结论,选择性BET BD2抑制剂的改善的安全性值得在BET相关疾病中进行进一步的研究。
