Biological Activity
MI-463 is a potent small-molecule inhibitor of the menin-MLL interaction. By disrupting the assembly of the menin-MLL protein complex, MI-463 suppresses downstream leukemogenic gene expression, specifically reducing HOXA9 and MEIS1 transcript levels. This block in menin-MLL signaling leads to the inhibition of cell proliferation, induction of cell cycle arrest, and promotion of differentiation in leukemic blast cells harboring MLL rearrangements.

| Solvent | Solubility & Note |
|---|---|
| DMSO |
96 mg/mL
(198.12 mM)
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO. The recommended stock concentration is 10 mM in DMSO.) |
| Ethanol | 22 mg/mL |
| Water | Insoluble |
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
- Preheat media/saline to 37°C.
- Mix rapidly (pipette/vortex) upon addition.
- For complex mixes, always add the aqueous phase last.
- Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
