Biological Activity

Description

MM-102 (HMTase Inhibitor IX) is a high-affinity peptidomimetic inhibitor of the WDR5/MLL1 protein-protein interaction, which bind to WDR5 with Ki < 1 nM and IC50 =2.4nM.

Targets

WDR5 ^[1]
(Cell-free assay)

2.4 nM

In vitro

MM-102, as a MLL1 mimetic, shows high binding affinities to WDR5 with IC50 of 2.9 nM and K_i of < 1 nM. In the MLL1-AF9 transduced murine cells, MM-102 specifically reduces expression of two critical MLL1 target genes (HoxA9 and Meis-1), which are required for MLL1 mediated leukemogenesis. In addition, MM-102 effectively and selectively inhibits cell growth and induces apoptosis in leukemia cells harboring MLL1 fusion proteins. ^[1]

Protocol (from reference)

Kinase Assay:^{^[1]}	In Vitro Histone Methyltransferase (HMT) Assay The HMT assay is performed in 50 mM HEPES pH 7.8, 100 mM NaCl, 1.0 mM EDTA, and 5% glycerol at 22 °C. Each reaction contains 1.5 μCi of the co-factor, ³H-S-adenosylmethionine. H3 10-residue peptide is used as the substrate at 50 μM. Compounds are added at concentrations ranging from 0.125 to 128 μM and incubated with the pre-assembled WDR5/RbBP5/ASH2L complex at a final concentration of 0.5 μM for each protein for 2–5 min. Reactions are initiated by addition of the MLL1 protein at a final concentration of 0.5 μM and allowed to proceed for 30 min before preparing scintillation counting. To count samples, reactions are spotted on separate squares of P81 filter paper and precipitated by submerging in freshly prepared 50 mM sodium bicarbonate buffer with pH 9.0. After washing and drying, samples are vortexed in Ultima Gold scintillation fluid and counted. As a negative control, assays are performed using 0.5 μM MLL1/WDR5/RbBP5/ASH2L complex assembled with the non-interacting mutant, WDR5D107A.
Cell Assay:^{^[1]}	Cell lines MV4;11, KOPN8, and K562 cells Concentrations ~100 μM Incubation Time 7 days Method MV4;11, KOPN8, and K562 cells are cultured in RPMI 1640 medium (ATCC) supplemented with 10% fetal bovine serum and 100 U/L penicillin-streptomycin and incubated at 37 °C under 5% CO₂. Cells are seeded into 12-well plates for suspension at a density of 5 × 10⁵ per well (1 mL) and treated with either vehicle control (DMSO, 0.2%) or MM-102 for 7 days. The medium is changed every 2 days, and compounds are resupplied. The CellTiter-Glo Luminescent Cell Viability Assay kit is used following the manufacturer’s instruction. First, 100 μL of the assay reagent is added into each well, and the content is mixed for 2 min on an orbital shaker to induce cell lysis. After 10 min incubation at room temperature, the luminescence is read on a microplate reader.
