molecular and cellular based assays. Throughout the study, compounds 9, 28 and 37 showed significant inhibitory activity for c-Myc or PD-L1 protein expression and mRNA transcription both at concentration of 0.2 and 1 μM. Compound 9 was found possessing the best balance of binding affinity, in vitro metabolic stability and in vivo pharmacokinetic properties. Therefore, it was selected for in vivo pharmacological
最近,发现了几种激酶抑制剂也抑制了溴结构域,为发现溴结构域抑制剂提供了新的策略。沿着这条路线,从PLK1-BRD4双重抑制剂BI-2536开始,我们发现了一系列新的二氢喹喔啉-2(1 H)-一类,其中苯胺和二氢吲哚WPF粘合剂作为选择性BRD4抑制剂。与BI-2536相比,它们显示出更好的BRD4-BD1效力和可忽略的PLK1激酶活性。此外,含吲哚啉基的二氢喹喔啉-2(1 H)-酮在基于分子和细胞的测定中显示出深远的活性。在整个研究中,化合物9,28和37在0.2和1μM的浓度下均显示出对c-Myc或PD-L1蛋白表达和mRNA转录的显着抑制活性。发现化合物9具有结合亲和力,体外代谢稳定性和体内药代动力学性质的最佳平衡。因此,它被选择用于体内药理研究。通过使用MM.1S细胞衍生的异种移植模型,我们证实了化合物9与II期研究药物I-BET762表现出相似的体内肿瘤抑制作用,该药物与新型WPF
