WDR5-47 (IC50 = 0.3 μM) was defined as a potent small molecule to disturb the interaction of MLL1-WDR5. Here, we described structure-based design and synthesis of small molecular inhibitors to block MLL1-WDR5 PPI. Especially, compound 23 (IC50 = 104 nM) was the most potent small molecular, and about 3-times more potent than WDR5-47. We also discussed the SAR of these series of compounds with docking study
MLL1复合物催化H3K4的甲基化,并在具有MLL融合蛋白的急性白血病的发展中起重要作用。靶向MLL1-WDR5蛋白-蛋白相互作用(P
PI)以抑制MLL1复合物的组蛋白甲基转移酶的活性是治疗急性白血病的一种新策略。WDR5-47(IC 50 = 0.3μM)被定义为干扰MLL1-WDR5相互作用的强力小分子。在这里,我们描述了基于结构的设计和小分子
抑制剂的合成以阻断MLL1-WDR5 P
PI。尤其是,化合物23(IC 50 = 104 nM)是最有效的小分子,其效力是WDR5-47的约3倍。我们还通过对接研究讨论了这些系列化合物的
SAR,这可能会刺激更有效的化合物。
