MI-2-2 is a potent menin-MLL inhibitor. MI-2-2 binds to menin with low nanomolar affinity (Kd=22nM) and very effectively disrupts the bivalent protein-protein interaction between menin and MLL. MI-2-2 has specific and very pronounced activity in MLL leukemia cells, including inhibition of cell proliferation, down-regulation of Hoxa9 expression, and differentiation[1].

In Vitro	MI-2-2 is capable of inhibiting both the interaction of menin with MBM1 (IC50= 46 nM) and with the bivalent fragment of MLL that comprises both MBM1 and MBM2 (IC50=520 nM). MI-2-2 exhibits very pronounced activities at low micromolar concentrations in BMCs transformed with MLL-AF9 and in MV4;11, a human leukemia cell line harboring the MLL-AF4 translocation[1].
