A number of diazepines are known to inhibit bromo- and extra-terminal domain (BET) proteins. Their BET inhibitory activity derives from the fusion of an acetyl-lysine mimetic heterocycle onto the diazepine framework. Herein we describe a straightforward, modular synthesis of novel 1,2,3-triazolobenzodiazepines and show that the 1,2,3-triazole acts as an effective acetyl-lysine mimetic heterocycle.
已知许多二氮杂卓可抑制溴末端和末端外域(BET)蛋白。它们的BET抑制活性源自乙酰赖氨酸模拟杂环在二氮杂骨架上的融合。在这里,我们描述了新颖的1,2,3-三唑并苯并二氮杂pine的简单,模块化合成,并表明1,2,3-三唑可作为有效的乙酰赖氨酸模拟杂环。该系列化合物的基于结构的优化导致开发出有效的BET溴结构域抑制剂,该抑制剂对白血病细胞具有出色的活性,并伴有c- MYC表达的降低。因此,这些新型苯并二氮杂pine代表了有前途的一类治疗性BET抑制剂。
