target. Therefore, identifying novel inhibitors with distinct properties could enrich their use in anticancer treatment. Guided by the cocrystal structure of hit compound 4 harboring a five-membered-ring linker motif, we quickly identified lead compound 7, which exhibited good antitumor effects in an MM.1S xenograft model by oral administration. Encouraged by its high potency and interesting scaffold,
BRD4最近已成为有前途的药物靶标。因此,鉴定具有独特性质的新型抑制剂可以丰富其在抗癌治疗中的应用。在具有五元环连接基序的命中化合物4的共晶体结构的指导下,我们快速鉴定了先导化合物7,该化合物在口服MM.1S异种移植模型中显示出良好的抗肿瘤作用。受其高效能和有趣的支架的鼓舞,我们进行了进一步的前导优化,以生成具有(1,2,4-triazol-5-yl)-3,4-的新型有效的bromodomain和末端外(BET)抑制剂系列。二氢喹喔啉-2(1 H)-一个结构。其中,化合物19被发现具有活性,稳定性和抗肿瘤功效的最佳平衡。确认其低脑部穿透力后,我们进行了全面的临床前研究,包括多物种药代动力学概况,广泛的细胞机制研究,hERG分析和体内抗肿瘤生长作用测试,我们发现化合物19是潜在的BET蛋白药物候选者用于治疗癌症。
