In HEK293 cells, MI-2 accessed the protein target and effectively inhibits the menin-MLL-AF9 interaction. MI-2 effectively blocks MLL fusion protein-mediated leukemic transformation by downregulating the expression of target genes required for MLL fusion protein oncogenic activity. MI-2 also effectively blocks cell proliferation, and induces cell apoptosis in human MLL leukemia cell lines harboring different MLL translocations.
