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.

Description

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[1].

IC50 & Target

IC50: 0.51 nM (menin-MLL1 interaction)[1]
In Vitro

MI-3454 (0.001-10 μM; 7 days) strongly reduces murine bone marrow cells transformed with MLL-AF9 or Hoxa9/Meis1 proliferation[1].
MI-3454 (50 nM; 6 days) leads to downregulated expression of HOXA9 and MEIS1 in Human leukemic cell lines MV-4-11 cells or MOLM13[1].
MI-3454 markedly reduces the viability of leukemic cells harboring various MLL fusion proteins (MLL-AF9, MLL-AF4, MLL-ENL), with GI50 values ranging from 7 to 27 nM. MI-3454 blocks the interaction of menin with an MLL14–43 fragment encompassing the entire menin binding motif[1].
MI-3454 does not potently inhibit cytochromes P450 (<50% inhibition at 10 μM)[1].

RT-PCR[1]

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.
In Vivo

MI-3454 induces complete remission or regression of leukemia in mouse models of mixed lineage leukemia 1 (MLL1)-rearranged or nucleophosmin 1 (NPM1)-mutated leukemia[1].
MI-3454 (p.o.; 120 mg/kg; one or twice daily for 7 consecutive days) sufficiently blocks leukemia progression by a once-daily treatment[1].
MI-3454 (p.o.; 100 mg/kg; b.i.d.; for 19 consecutive days) effectively blocks leukemia progression during the treatment period and markedly prolongs survival of MOLM13 xenotransplantation model mice. MI-3454 induces complete remission or blocks leukemia progression in patient-derived xenograft (PDX) models of MLL leukemia[1].
MI-3454 (100 mg/kg of PO or 15 mg/kg of IV) has a T1/2 of 3.2 hours, a Cmax of 4698 mg/mL for PO[1].
MI-3454 exhibits favorable stability in murine and human liver microsomes (t1/2=20.4 minutes and 37.1 minutes, respectively)[1].
MI-3454 demonstrates lower levels in brain and cerebrospinal fluid, suggesting limited ability to cross the blood-brain barrier[1].

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
