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 Assay:[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 Study:[1]
  • Animal Models

    C57BL/6 mice

  • Dosages
