Menin是致癌MLL融合蛋白的重要辅助因子,Menin -MLL相互作用对体内急性白血病的发展至关重要。利用小分子靶向menin-MLL相互作用是开发新型抗癌药物的一种有吸引力的策略。最近的研究进展,包括对menin晶体结构的测定以及有效的小分子和拟肽抑制剂的开发,证明了靶向menin- mll相互作用的可行性。另一方面,生化和结构研究表明,MLL以复杂的二价模式与menin结合,涉及两个MLL基序,因此抑制这种蛋白质-蛋白质相互作用是一个挑战。本文综述了针对menin- mll相互作用的最新研究成果,并讨论了阻断menin在癌症中的潜在益处。
Menin is an essential co-factor of oncogenic MLL fusion proteins and the menin-MLL interaction is critical for development of acute leukemia in vivo. Targeting the menin-MLL interaction with small molecules represents an attractive strategy to develop new anticancer agents. Recent developments, including determination of menin crystal structure and development of potent small molecule and peptidomimetic inhibitors, demonstrate feasibility of targeting the menin-MLL interaction. On the other hand, biochemical and structural studies revealed that MLL binds to menin in a complex bivalent mode engaging two MLL motifs, and therefore inhibition of this protein-protein interaction represents a challenge. This review summarizes most recent achievements in targeting the menin-MLL interaction as well as discusses potential benefits of blocking menin in cancer.
