Cat.No.S9871

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

Mechanism of Action

Targets/IC₅₀/Ki	IMP1 c-Myc NF-κB
In vitro	In cells, BTYNB downregulates several mRNA transcripts regulated by IMP1. This compound destabilizes c-Myc mRNA, resulting in downregulation of c-Myc mRNA and protein. It 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 this chemical to inhibit tumor cell protein synthesis. It potently inhibits proliferation of IMP1-containing ovarian cancer and melanoma cells with no effect in IMP1-negative cells. Overexpression of IMP1 reverses its inhibition of cell proliferation. This compound completely blocks anchorage-independent growth of melanoma and ovarian cancer cells in colony formation assays.
