Application

bpV(HOpic) has been used in pharmacological perturbation of cell migration related signaling pathway.

Biochem/physiol Actions

bpV(OHpic) is a bisperoxovanadium inhibitor of protein phosphotyrosine phosphatases with selectivity for PTEN, phosphatase and tensin homolog, a tumour suppressor phosphatase involved in cell cycle regulation. IC50 values for bpV(HOpic) are 14 nM for PTEN compared to 4.9 μM for PTPβ and 25.3 μM for PTP-1β. bpV(HOpic) has been shown to enhance PI3K/Akt signaling that could prevent myocardium from ischemia-reperfusion injury.

Other Notes

Soluble in DMSO or water. NOTE: The product is not stable in water. Decomposition starts immediately after solubilization. Rate of decomposition is slower in dry DMSO.
