The bromodomain containing proteins BAZ2A/B play essential roles in chromatin remodeling and regulation of noncoding RNAs. We present the structure based discovery of a potent, selective, and cell active inhibitor 13 (BAZ2-ICR) of the BAZ2A/B bromodomains through rapid optimization of a weakly potent starting point. A key feature of the presented inhibitors is an intramolecular aromatic stacking interaction
含溴结构域的蛋白质 BAZ2A/B 在染色质重塑和非编码 RNA 的调节中发挥重要作用。我们通过对弱效起点的快速优化,提出了基于结构的 BAZ2A/B 溴结构域的有效、选择性和细胞活性抑制剂13 (BAZ2-ICR) 的发现。所提出的抑制剂的一个关键特征是分子内芳香族堆积相互作用,有效地占据了浅溴结构域口袋。图13代表用于体外和体内BAZ2溴结构域功能研究的优秀化学探针。
