The bromodomain and extra-terminal domain (BET) family of proteins bind acetylated lysine residues on histone proteins. The four BET bromodomains—BRD2, BRD3, BRD4, and BRDT—each contain two bromodomain modules. BET bromodomain inhibition is a potential therapy for various cancers and immunoinflammatory diseases, but few reported inhibitors show selectivity within the BET family. Inhibitors with selectivity
蛋白质的溴结构域和末端外结构域(BET)家族结合组蛋白上的乙酰化赖氨酸残基。四个BET溴结构域-BRD2,BRD3,BRD4和BRDT-每个都包含两个溴结构域模块。BET溴结构域抑制是多种癌症和免疫炎性疾病的潜在疗法,但很少有报道的抑制剂在BET家族中显示出选择性。需要对第一或第二溴结构域具有选择性的抑制剂以帮助研究这些结构域的生物学功能。重点文库筛选确定了一系列对BET家族(BD2)的第二个溴结构域具有选择性的四氢喹喔啉。模板的结构指导优化提高了效能,选择性和物理化学性质,最终产生了具有BD2选择性的强效BET抑制剂。
