interaction is a promising new therapeutic strategy for the treatment of acute leukemia carrying MLL fusion (MLL leukemia). We describe herein our structure-based design, synthesis, and evaluation of a new class of small-molecule inhibitors of the menin-MLL interaction (hereafter called menin inhibitors). Our efforts have resulted in the discovery of highly potent menin inhibitors, as exemplified by compound
抑制Menin混合谱系白血病(MLL)蛋白-蛋白相互作用是一种治疗带有MLL融合的急性白血病(MLL白血病)的有前途的新治疗策略。我们在本文中描述了我们基于结构的设计,合成和评估一类新型的Menin-MLL相互作用的小分子抑制剂(以下称为Menin抑制剂)。我们的努力导致发现了高效的menin抑制剂,如化合物42(M-89)所示。M-89以1.4 nM的Kd值与Menin结合,并在低纳摩尔浓度下有效地与细胞Menin蛋白结合。M-89抑制带有MLL融合的MV4; 11和MOLM-13白血病细胞系的细胞生长,其IC50值分别为25和55 nM,并且相对于缺乏MLL融合的HL-60白血病细胞系表现出> 100倍的选择性。与Menin的复合物中M-89的共晶体结构的确定为其高亲和力相互作用提供了结构基础。M-89的进一步优化可能会导致治疗MLL白血病的新疗法。
