抑制Menin（MEN1）和MLL（MLL1，KMT2A）相互作用是MLL重排（MLL-r）白血病的潜在治疗策略。基于结构的设计产生了有效的，高选择性的，可口服生物利用的小分子抑制剂VTP50469。带有MLL重排的细胞系对VTP50469有选择性的反应。VTP50469使Menin脱离了蛋白质复合物，并抑制了某些基因上MLL的染色质占据。MLL结合的丧失导致基因表达，分化和凋亡的改变。使用VTP50469治疗时，来自患有MLL-r急性髓细胞性白血病或MLL-r急性淋巴细胞性白血病（ALL）的患者的患者异种移植（PDX）模型显示白血病负担显着降低。治疗后多只移植有MLL-r ALL的小鼠保持无病超过1年。
