MI-3454

Research use only, not for human use.

MI-3454 is an orally active, selective and potent inhibitor of Menin-MLL1 interaction that inhibits the proliferation and induces differentiation of acute leukemia cells with MLL1 translocation or NPM1 mutation.

MI-3454 is an orally active, highly potent and selective menin-MLL1 interaction inhibitor with an IC50 of 0.51 nM. MI-3454 inhibits proliferation, induces differentiation and complete remission or regression of leukemia in mouse models of MLL1-rearranged or NPM1-mutated leukemia through downregulation of key genes involved in leukemogenesis.

Cell Proliferation Assay Cell Line:Murine bone marrow cells transformed with MLL-AF9 or Hoxa9/Meis1 Concentration:0.001, 0.01, 0.1, 1, 10 μM Incubation Time:7 days Result:Demonstrated strong reduction of cell proliferation.RT-PCR Cell Line:Human leukemic cell lines MV-4-11 cells or MOLM13 Concentration:50 nM Incubation Time:6 days Result:Led to downregulated expression of HOXA9 and MEIS1 and expression level of other MLL fusion target genes, including MEF2C, DLX2, HOXA10, PBX3, and FLT3.

Animal Model:8- to 10-week-old female NSG mice (MV-4-11 xenotransplantation model of MLL leukemia) Dosage:120 mg/kg Administration:Orally; one or twice daily for 7 consecutive daysResult:A once-daily treatment was sufficient to block leukemia progression. Animal Model:Female CD-1 mice Dosage:100 mg/kg (PO) or 15 mg/kg (IV) (Pharmacokinetic Analysis) Administration:PO or IV Result:Had a T1/2 of 3.2 hours, a Cmax of 4698 mg/mL for PO. Had a T1/2 of 2.4 hours, a CL of 2375 mL/hours?kg, and a Vss of 5358 mL/kg for IV.
