reported inhibitors show selectivity within the BET family. Herein, we identified a series of benzo[cd]indol-2(1H)-ones and pyrrolo[4,3,2-de]quinolin-2(1H)-ones with good selectivity for BET BD1. Through structure-based optimization, highly active and selective compounds are ultimately obtained. The representative compounds are the first reported inhibitors with selectivity more than 100-fold for BRD4(1)
蛋白质的溴结构域和末端外结构域(BET)家族是特异识别组蛋白乙酰化赖氨酸残基的阅读器。每个BET溴结构域蛋白都包含两个高度同源的结构域:第一个溴结构域(BD1)和第二个溴结构域(BD2)。Pan-BET bromodomain抑制是一种对多种癌症和免疫炎性疾病的潜在疗法,但只有极少数报道的抑制剂在BET家族中显示出选择性。在本文中,我们确定了一系列对BET BD1具有良好选择性的苯并[cd] indol-2(1H)-和吡咯并[4,3,2-de]喹啉-2(1H)-。通过基于结构的优化,最终获得了高活性和选择性的化合物。代表性化合物是最先报道的抑制剂,其对BRD4(1)的选择性超过BRD4(2)的100倍以上。他们之中,我们进一步显示68(LT052)介导具有可比蛋白质表达的BRD4 /NF-κB/ NLRP3信号传导炎症途径,并显着改善了大鼠模型中痛风性关节炎的症状。因此,对单个溴结构域的选
