Mechanism of Action

Targets/IC50/Ki
Menin-MLL interaction
648 nM
In vitro
In HEK293 cells, MI-3 (Menin-MLL Inhibitor) accesses the protein target and effectively inhibits the menin-MLL-AF9 interaction. It effectively blocks MLL fusion protein-mediated leukemic transformation by downregulating the expression of target genes required for MLL fusion protein oncogenic activity. In human MLL leukemia cell lines harboring different MLL translocations, this compound effectively blocks cell proliferation and induces apoptosis.
Kinase Assay
High Throughput Screening
MI-3 (Menin-MLL Inhibitor) is screened as follows: FITC-MBM1 at 15 nM and menin at 150 nM in the FP buffer are mixed and incubated for 1h in the dark at room temperature. For point screening, 0.2 μL of each compound (20 μM final concentration, 1% DMSO) is added to 20 μL of the aliquot of the protein-peptide mixture and incubated on 384-well plates in the dark at room temperature for 1h. In confirmation screening, the serial dilution plates with this compound in DMSO are prepared and used to titrate the menin-FITC-MBM1 complex. Change in fluorescence polarization is monitored at 525 nm after excitations at 495 nm using the PHERAstar microplate reader (BMG) and applied to determine IC50 values with the Origin 7.0 program.
