Biological Activity

Description BTYNB (BTYNB IMP1 Inhibitor, MDK6620) is a potent and selective inhibitor of IMP1 binding to c-Myc mRNA. BTYNB downregulates β-TrCP1 mRNA and reduces activation of nuclear transcriptional factors-kappa B (NF-κB). BTYNB disrupts this enhancer function by impairing IGF2 mRNA-binding protein 1 (IGF2BP1)-RNA association.
Targets
IMP1 [1] c-Myc [1] NF-κB [1]
In vitro

In cells, BTYNB downregulates several mRNA transcripts regulated by IMP1. BTYNB destabilizes c-Myc mRNA, resulting in downregulation of c-Myc mRNA and protein. BTYNB downregulates β-TrCP1 mRNA and reduces activation of nuclear transcriptional factors-kappa B (NF-κB). The oncogenic translation regulator, eEF2, emerges as a new IMP1 target mRNA, enabling BTYNB to inhibit tumor cell protein synthesis. BTYNB potently inhibits proliferation of IMP1-containing ovarian cancer and melanoma cells with no effect in IMP1-negative cells. Overexpression of IMP1 reverses BTYNB inhibition of cell proliferation. BTYNB completely blocks anchorage-independent growth of melanoma and ovarian cancer cells in colony formation assays.[1]

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    SK-MEL2 cells

  • Concentrations

    10 μM

  • Incubation Time

    24 h

  • Method

    For stability experiments, SK-MEL2 cells are treated with either DMSO or 10 μM BTYNB for 24 hours. mRNA synthesis is inhibited by treatment with 5 μM Actinomycin D (mRNA decay), and the cells are harvested at the indicated time points.
