reported BET inhibitors were monovalent inhibitors. Recently, some bivalent inhibitors were disclosed, which bound to two bromodomains simultaneously. They had good activities, however, most of them also showed unsatisfactory pharmacokinetic properties, which were caused by long chain linkers. Based on our previous work on monovalent BRD4 inhibitors, we designed and synthesized a series of novel bivalent
溴结构域和末端外结构域 (BET) 亚家族成员是癌症治疗的有趣目标。大多数报道的 BET 抑制剂是单价抑制剂。最近,公开了一些二价抑制剂,它们同时与两个溴结构域结合。它们具有良好的活性,但它们中的大多数也表现出不令人满意的药代动力学特性,这是由长链接头引起的。基于我们之前对单价 BRD4 抑制剂的研究,我们设计并合成了一系列具有短且亲水性接头的新型二价抑制剂。这些化合物表现出比相应的单价抑制剂更好的活性和良好的药代动力学特性。化合物21表现出优异的体外活性。并且也表现出了强大的口服给药下的体内抗肿瘤功效,并且在体内试验中耐受性良好。
