Biological Activity:

MM-102 is a highly potent and selective inhibitor of the MLL1/WDR5 interaction with an IC50 ~2.9 nM binding affinity to WDR5. 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. MM-102 also specifically inhibits cell growth and induces apoptosis in leukemia cells harboring MLL1 fusion proteins.  MM-102 provides the first proof-of-concept small molecule inhibitor to target the WDR5/MLL1 protein-protein interaction as a novel therapeutic approach for acute leukemia harboring MLL1 fusion proteins.


How to Use:


  • In vitro:  MM-102 was suggested to be used at 10-100 µM final concentration in vitro and in cellular assays. 
  • In vivo:  n/a
