MM-102 TFA (HMTase Inhibitor IX TFA) is a potent WDR5/MLL interaction inhibitor, achieves IC50 = 2.4 nM with an estimated Ki < 1 nM in WDR5 binding assay, which is >200 times more potent than the ARA peptide.
MM-102 (HMTase Inhibitor IX) inhibits MLL1 methyltransferase activity and MLL-1-induced HoxA9 and Meis-1 gene expression in leukemia cells expressing the MLL1-AF9 fusion gene. Also inhibits cell growth and induces apoptosis in leukemia cells harbouring MLL1 fusion proteins. MM-102 (TFA), with the highest binding affinities to WDR5, also show the most potent inhibitory activity in the HMT assay withIC50=0.4-0.9 μM[1]. MM-102 (HMTase Inhibitor IX) dose-dependently inhibits cell growth in the MV4;11 and KOPN8 leukemia cell lines, which carry MLL1-AF4 and MLL1-ENL fusion proteins, respectively[1]. MM-102 (HMTase Inhibitor IX) has IC50=25 μM in both cell lines and completely inhibits cell growth in these cell lines at 75 μM[1]. MM-102 (HMTase Inhibitor IX) effectively and selectively inhibits cell growth and induces apoptosis in leukemia cells harboring MLL1 fusion proteins and has minimal effect in leukemia cells with wild-type MLL1 protein[1].
