Biological Activity

Description MI-463 is a potent inhibitor of Menin-MLL interaction with an IC50 value of 15.3 nM.
Targets
Menin-MLL interaction [1]
(Cell-free assay)
15.3 nM
In vitro

MI-463 demonstrates profound on-target activity in MLL leukemia cells. MI-463 results in substantial growth inhibition, with half-maximal growth inhibitory concentration (GI50) values of 0.23 μM, measured after 7 days of treatment in MLL leukemia cells. MI-463 is effective in inducing differentiation of MLL leukemia cells. Treatment with sub-micromolar concentrations of MI-463 also leads to markedly reduced expression of Hoxa9 and Meis1, downstream targets of MLL fusion proteins substantially upregulated in MLL leukemias[1].

In vivo MI-463 shows substantial survival benefit in mouse models of MLL leukemia. It has very favorable druglike properties, including metabolic stability and PK profile in mice. MI-463 achieves high levels in peripheral blood following a single intravenous or oral dose, while also showing high oral bioavailability(∼45%). In a mouse xenograft model using MV4;11 human MLL leukemia cells implanted into BALB/c nude mice, MI-463 induces strong inhibition of tumor growth with once-daily intraperitoneal (i.p.) administration. It does not impair normal hematopoiesis in vivo[1].

Protocol (from reference)

Cell Research:[1]
  • Cell lines: leukemia cells
  • Concentrations: --
  • Incubation Time: 6 or 7 days
  • Method: For viability assays, leukemia cells are plated at relevant concentrations and treated with compounds or 0.25% DMSO and cultured at 37°C for 7 days. Medium is changed at day 4, viable cell numbers are restored to the original concentration, and compounds are re-supplied. The MTT cell proliferation assay kit (Roche) is then used, and plates are read for absorbance at 570 nm using a PHERAstar BMG microplate reader. Effect of menin-MLL inhibitors on expression level is assessed by qRT-PCR after 6 days of incubation of compounds with cells, with medium changed and compound re-supply at day 3. For cell differentiation studies, leukemia cells are treated with menin-MLL inhibitors for 7 days, then harvested, washed, and incubated with Pacific Blue rat anti-mouse CD11b antibody before being analyzed by flow cytometry.
Animal Research:[1]

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.
