Concomitant inhibition of anaplastic lymphoma kinase (ALK) and bromodomain-4 (BRD4) is a potential therapeutic strategy for targeting two key oncogenic drivers that co-segregate in a significant fraction of high-risk neuroblastoma patients, mutation of ALK and amplification of MYCN. Starting from known dual polo-like kinase (PLK)-1-BRD4 inhibitor BI-2536, we employed structure-based design to redesign
同时抑制间变性淋巴瘤激酶 (ALK) 和溴结构域-4 (BRD4) 是一种潜在的治疗策略,用于靶向在高危神经母细胞瘤患者中共同分离的两个关键致癌驱动因素、ALK 突变和 MYCN 扩增。从已知的双 polo 样激酶 (PLK)-1-BRD4 抑制剂 BI-2536 开始,我们采用基于结构的设计将这个系列重新设计为具有双 ALK-BRD4 谱的化合物。这些努力导致化合物 (R)-2-((2-乙氧基-4-(1-甲基哌啶-4-基)苯基)氨基)-7-乙基-5-甲基-8-((4-甲基噻吩-2 -yl)methyl)-7,8-dihydropteridin-6(5 H)-one (16k) 表明 ALK 活性提高并显着降低 PLK-1 活性,同时保持 BRD4 活性和整体激酶组选择性。我们展示了化合物
