MI-2 (MI2, Menin-MLL Inhibitor) is a novel, potent and selective inhibitor of menin-MLL interaction with antineoplastic activity. It inhibits menin-MLL interaction with an IC50 of 446 nM. MI-2 acts by binding to the wild-type menin but doesn't bind M278K and Y323K menin mutants. In HEK293 cells transfected with Flag-MLL-AF9, MI-2 effectively inhibited the menin-MLL-AF9 interaction without affecting the expression level of menin and MLL-AF9.
| ln Vitro |
The menin-MLL inhibitor MI-2, with GI50 values of approximately 5 μM, very efficiently inhibits the proliferation of MLL-AF9 and MLL-ENL transduced BMC. Several compounds with IC50 values in the nanomolar range were developed as a result of the assessment of various hydrophobic groups at R1. These compounds include MI-2 (IC50= 446±28 nM) and MI-3 (IC50= 648±25 nM). The dissociation constants (Kd=158 nM for MI-2) for the menin-MLL inhibitors have been measured at the nanomolar range. Inhibiting the menin-MLL-AF9 connection in human cells is a highly effective way that MI-2 can access the protein target. Moreover, MI-2 exhibits minimal impact on the proliferation of BMC transduced with E2A-HLF (GI50>50 μM). This could potentially be attributed to the inhibition of menin interaction with wild-type MLL. After MI-2 treatment, GI50 values for MV4;11 (harboring MLL-AF4; GI50=9.5 μM), KOPN-8 (MLL-ENL; GI50=7.2 μM), ML-2 (MLL-AF6; GI50=8.7 μM), and MonoMac6 (MLL-AF9; GI50=18 μM) are less than 10 μM[1].

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution 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 stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O，mix and clarify.
(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
(2) Be sure to add the solvent(s) in order.
