MI-463 is a potent and orally bioavailable inhibitor of the menin-mLL interaction (IC50: 15.3 nM).

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

For efficacy studies in MV4;11 subcutaneous xenograft mice model, 5×10^6 cells are injected into the 4-6 week old female BALB/c nude mice. Treatment is started when the tumor size reached ~100 mm^3. Vehicle (25% DMSO, 25% PEG400, 50% PBS) or MI-463 are administrated once daily at designated doses using i.p. injections.
