- Design of the First-in-Class, Highly Potent Irreversible Inhibitor Targeting the Menin-MLL Protein–Protein Interaction
-
The structure-based design of M-525 as the first-in-class, highly potent, irreversible small-molecule inhibitor of the menin-MLL interaction is presented. M-525 targets cellular menin protein at sub-nanomolar concentrations and achieves low nanomolar potencies in cell growth inhibition and in the suppression of MLL-regulated gene expression in MLL leukemia cells. M-525 demonstrates high cellular specificity over non-MLL leukemia cells and is more than 30 times more potent than its corresponding reversible inhibitors. Mass spectrometric analysis and co-crystal structure of M-525 in complex with menin firmly establish its mode of action. A single administration of M-525 effectively suppresses MLL-regulated gene expression in tumor tissue. An efficient procedure was developed to synthesize M-525. This study demonstrates that irreversible inhibition of menin may be a promising therapeutic strategy for MLL leukemia.

- Structure-Based Discovery of M-89 as a Highly Potent Inhibitor of the Menin-Mixed Lineage Leukemia (Menin-MLL) Protein-Protein Interaction
-
Inhibition of the menin-mixed lineage leukemia (MLL) protein-protein 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 42 (M-89). M-89 binds to menin with a Kd value of 1.4 nM and effectively engages cellular menin protein at low nanomolar concentrations. M-89 inhibits cell growth in the MV4;11 and MOLM-13 leukemia cell lines carrying MLL fusion with IC50 values of 25 and 55 nM, respectively, and demonstrates >100-fold selectivity over the HL-60 leukemia cell line lacking MLL fusion. The determination of a co-crystal structure of M-89 in a complex with menin provides the structural basis for their high-affinity interaction. Further optimization of M-89 may lead to a new class of therapy for the treatment of MLL leukemia.
