highly potent BET bromodomain inhibitors. Further druggability optimization led to the discovery of compound 38 as a potential preclinical candidate. Significantly, compared with ABBV-075, which exhibits a 63-fold selectivity for BRD4(1) over EP300, compound 38 demonstrates an excellent selectivity for the BET bromodomain family over other bromodomains, with an ∼1500-fold selectivity for BRD4(1) over
溴结构域和末端外(BET)家族蛋白最近已成为有希望的癌症治疗药物靶标。在这项研究中,鉴定了一个8-甲基-吡咯并[1,2-a]吡嗪-1(2H)-一个片段(47)作为BET溴结构域的新结合物,随后将片段47掺入了该载体的支架中。最近进入I期临床试验的ABBV-075使能够产生一系列高效的BET溴结构域抑制剂。进一步的可药物性优化导致发现化合物38作为潜在的临床前候选药物。值得注意的是,与ABBV-075相比,BBB4(1)对BRD4(1)的选择性是EP300的63倍,化合物38对BET溴结构域家族的选择性比其他溴结构域好,而BRD4(1)的选择性约为1500倍。超过EP300。
