  3. MMRi6

MMRi6 is a Mdm2-MdmX RING domain inhibitor that can disrupt Mdm2-MdmX RING-RING interaction in vitro. MMRi6 inhibits MdmX-stimulated Mdm2 autoubiquitination and Mdm2-MdmX-mediated p53 polyubiquitination in vitro without affecting NEDD4-1 autoubiquitination. MMRi6 induces p53 stabilization and accumulation and induces PARP cleavage in wt-p53 Emu-myc lymphoma cells. MMRi6 inhibits the growth of wt-p53 and p53-null Emu-myc lymphoma cells with IC50s of approximately 0.5 μM and 3 μM, respectively. MMRi6 can be used for the study of leukemia/lymphoma.

Description

MMRi6 is a Mdm2-MdmX RING domain inhibitor that can disrupt Mdm2-MdmX RING-RING interaction in vitro. MMRi6 inhibits MdmX-stimulated Mdm2 autoubiquitination and Mdm2-MdmX-mediated p53 polyubiquitination in vitro without affecting NEDD4-1 autoubiquitination. MMRi6 induces p53 stabilization and accumulation and induces PARP cleavage in wt-p53 Emu-myc lymphoma cells. MMRi6 inhibits the growth of wt-p53 and p53-null Emu-myc lymphoma cells with IC50s of approximately 0.5 μM and 3 μM, respectively. MMRi6 can be used for the study of leukemia/lymphoma[1].

In Vitro

MMRi6 (10 μM) inhibits Mdm2 autoubiquitination and p53 ubiquitination by Mdm2–MdmX in vitro[1].
MMRi6 (5 μM, 8 h) induces p53 protein accumulation in HCT-8 cells and in wt-p53 Emu-myc lymphoma cells[1].
MMRi6 (0.5 μM, 24 h) induces PARP cleavage in wt-p53 Emu-myc lymphoma cells but not in p53-null Emu-myc lymphoma cells[1].
MMRi6 (0.5-1 μM, 72 h) inhibits the growth of wt-p53 and p53-null Emu-myc lymphoma cells with IC50s of approximately 0.5 μM and 3 μM, respectively[1].

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.
