Within the last decade, the Bromodomain and Extra-Terminal domain family (BET) of proteins have emerged as promising drug targets in diverse clinical indications including oncology, auto-immune disease, heart failure, and male contraception. The BET family consists of four isoforms (BRD2, BRD3, BRD4, and BRDT/BRDT6) which are distinguished by the presence of two tandem bromodomains (BD1 and BD2) that independently
在过去的十年中,蛋白质的Bromodomain和Extra-Terminal域家族(BET)在各种临床适应症(包括肿瘤学,自身免疫性疾病,心力衰竭和男性避孕)中已成为有希望的药物靶标。BET家族由四个同工型(BRD2,BRD3,BRD4和BRDT / BRDT6)组成,其特征在于存在两个串联的溴结构域(BD1和BD2),它们独立识别乙酰化赖氨酸(KAc)残基,并且似乎具有独特的生物学特性角色。BET BD1和BD2溴结构域在底物结合口袋附近的五个位置处不同:ZA通道中的变化会诱导附近的不同水网络。我们设计了一组同类的2和3杂芳基取代的四氢喹啉(THQ),以差异地结合ZA通道中的结合水,以实现溴结构域选择性。SJ830599(9)显示出对BRD2-BD2的适度但一致的选择性。使用等温滴定量热法,我们显示在我们的研究中所有THQ类似物与两个溴结构域之一的结合都是焓驱动的。显着地,9与BRD2-
