Biological Activity

Description MI-3 (Menin-MLL Inhibitor) is a potent menin-MLL interaction inhibitor with IC50 of 648 nM.
Targets
Menin-MLL interaction [1]
()
648 nM
In vitro

In HEK293 cells, MI-3 accesses the protein target and effectively inhibits the menin-MLL-AF9 interaction. MI-3 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, MI-3 effectively blocks cell proliferation, and induces apoptosis. [1]

Protocol (from reference)

Kinase Assay:

[1]

  • High Throughput Screening:

    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, the 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 compounds 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.

Cell Research:

[1]

  • Cell lines: MLL-AF9 and E2A-HLF transduced murine BMC
  • Concentrations: ~20 μM
  • Incubation Time: 12 days
  • Method:

    The MLL-AF9 and E2A-HLF transduced murine BMC are plated in 12-well plates at the concentration of 5×103 cells/mL with 1 mL methylcellulose medium M3234 containing 20% IMDM medium, 1% penicillin/streptomycin, IL-3 and 0.25% DMSO or compounds. 6 days later colonies are stained with 100 μL iodonitrotetrazolium chloride at final concentration of 1 mg/mL, incubated at 37°C for 30 min and counted. To replate for the 2nd round, colonies are counted at day 6 without staining and cells were washed out by 1×PBS buffer and resuspended in IMDM medium containing 15% FBS, 1% penicillin/streptomycin and IL-3. 5×103 cells are plated in 12-well plates with 1ml methylcellulose medium M3234 containing 20% IMDM medium, 1% penicillin/streptomycin, IL-3 and 0.25% DMSO or compounds. 6 days later colonies are stained and counted.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
