MI-538 is an inhibitor of the interaction between menin and MLL fusion proteins with an IC50 of 21 nM.
MI-538 inhibits the proliferation of MLL leukemia cells with a GI50 of 83 nM. MI-538 shows no effect (up to 6 μM) on growth of the control cell lines HL-60 and HM-2, which do not harbor MLL translocations, demonstrating good selectivity toward MLL fusion protein transformed cells. MI-538 binds to menin with low nanomolar affinity (Kd=6.5 nM). Its potent cellular activity originates from the improved binding affinity to menin and possibly increased cell membrane permeability. Treatment with MI-538 results in strong down regulation of expression of Hoxa9 and Meis1 genes. About 100 nM 27 was sufficient to reduce by ~50% Hoxa9 expression in MLL-AF9 cells, and even more pronounced effect was seen on Meis1 expression[1].
Treatment with MI-538 results in a pronounced, about 80%, reduction in the MV4;11 tumor volume, without causing substantial signs of toxicity reflected by less than 10% reduction of the body weight. MI-538 demonstrates markedly improved exposure (area under the curve, AUC, values), Cmax (maximum compound concentration) in the blood plasma, and the lowest value of clearance. The half-life of MI-538 is about 1.6 h. MI-538 has also high oral bioavailability (~50%)[1].

Cell experiment: | MOLM-13, MV4;11, HL-60 human leukemia cells as well as MLL-AF9 and HM-2 murine bone marrow cells are treated with MI-538 or 0.25% DMSO for 7 days. Media are changed at day 4 with viable cell number restored to the original concentration, and MI-538 are resupplied. An amount of 100 μL of cell suspension is transferred to 96-well plates for each sample in quadruplicates. Cell viability is measured using the MTT assay. Plates are read for absorbance at 570 nm[1]. |
Animal experiment: | Mice: Mice xenograft are randomly grouped with each group containing eight mice. Vehicle or MI-538 (45 mg/kg) are administrated once daily at designated doses using ip injections for 2 weeks. Body weight and tumor sizes are monitored three times a week[1]. |

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |
