合成了一系列大体积有机金属和有机类似物溴域(BRD)抑制剂(+)-JQ1。最强的N‐[(adamantan‐1‐yl)methyl]‐2‐[(9S)‐7‐(4‐chlorophenyl)‐4,5,13‐trimethyl‐3‐thia‐1,8,11,12‐tetraazatricyclo[8.3.0.02,6]trideca‐2(6),4,7,10,12‐pentaen‐9‐yl]acetamide,2e,表现出很好的效力,a KD=约130 nmvs。BRD4(1)和aca.比BrD4(2)有2倍的选择性(Kd=约260 nm)。它与BRD4的第一个溴区的结合是由蛋白质共晶体结构决定的。
A series of bulky organometallic and organic analogues of the bromodomain (BRD) inhibitor(+)‐JQ1have been prepared. The most potent,N‐[(adamantan‐1‐yl)methyl]‐2‐[(9S)‐7‐(4‐chlorophenyl)‐4,5,13‐trimethyl‐3‐thia‐1,8,11,12‐tetraazatricyclo[8.3.0.02,6]trideca‐2(6),4,7,10,12‐pentaen‐9‐yl]acetamide,2e, showed excellent potency with anKD=ca. 130 nmvs. BRD4(1) and aca. 2‐fold selectivity over BRD4(2) (KD=ca. 260 nm). Its binding to the first bromodomain of BRD4 was determined by a protein cocrystal structure.
