MI-463 is a highly potent and orally bioavailable small molecule inhibitor of the menin-mLL interaction.

MI-463 can reach the target protein in mammalian cells and effectively inhibit the menin-mLL-AF9 interaction at sub-micromolar concentrations. Treatment of murine bone marrow cells (BMC) transformed with the mLL-AF9 oncogene with MI-463 results in substantial growth inhibition, with GI₅₀ of 0.23 μM^[1].

MI-463 achieves high level in peripheral blood following a single intravenous or oral dose, while also showing high oral bioavailability (45%). Pharmacologic inhibition of the menin-mLL interaction substantially delays progression of mLL leukemia in murine models through on-target activity without causing toxicity. MI-463 induces strong inhibition of tumor growth with once daily intraperitoneal (i.p.) administration. The expression of mLL fusion protein target genes, HOXA9 and MEIS1, are significant reduced upon treatment with MI-463. 20 days treatment of MV4;11 xenograft recipient mice with MI-463 also results in a substantial delay in leukemia progression as manifested by a marked decrease in the bioluminescence level which is associated with a significant decrease in the population of leukemic cells in the peripheral blood, spleen and bone marrow samples^[1].

Leukemia cells are treated with MI-463 or 0.25% DMSO and cultured at 37 °C for 7 days. Media is changed at day 4, viable cell numbers are restored to the original concentration and MI-463 are re-supplied. MTT cell proliferation assay kit is then employed, and plates are read for absorbance at 570 nm using a microplate reader^[1].

Mice: For efficacy studies in MV4;11 subcutaneous xenograft mice model, 5×10⁶ cells are injected into the 4-6 week old female BALB/c nude mice. Treatment is started when the tumor size reached ~100 mm³. Vehicle (25% DMSO, 25% PEG400, 50% PBS) or compounds (MI-463 or MI-503) are administrated once daily at designated doses using i.p. injections^[1].
