General description
A cell-permeable peptidomimetic that competes against MLL1 (Mixed Lineage Leukemia 1) minimum essential WIN (WDR5 INteracting) motif (-Ala3764-Arg-Ala3766-) for WDR5 (Trp-Asp Repeat Domain 5) binding (IC50/Ki = 2.5 nM/<1 nM and 540 nM/120 nM, respectively), effectively preventing MLL1 from complex assembling with WDR5, RbBP5 (Retinoblastoma Binding Protein 5), and ASH2L (Absent Small or Homeotic-2-Like) for enhanced H3K4 methyltransferase activity (IC50 = 0.4 nM). Shown to reduce HoxA9 and Meis-1 mRNA expression (by 76% and 36%, respectively, after 96 h 50 µM MM-102 treatment) in myeloblasts derived from MLL1-AF9-transduced murine bone marrow cells and preferentially inhibit the growth of MLL1-AF4-harboring MV4;11 and MLL1-ENL-harboring KOPN8 leukemia cultures (GI50 in 7 days = 25 µM) via apoptosis induction (by >75% in 4 days in MV4:11 cultures; 50 µM MM-102), while exhibiting much reduced potency against BCR-ABL-dependent K562 cells (GI50 in 7 days = 84 µM; >90 live cells after 4-day 50 µM MM-102 treatment).
