    Product Description

    bpV(phen) is a bisperoxovanadium (bpV) compound which inhibits several different protein tyrosine phosphatases (PTPs), with selectivity for PTEN (IC50 = 38 nM).1,2 It also inhibits the vascular endothelial PTP, PTP-β (IC50 = 343 nM), and PTP-1β (IC50 = 920 nM).2,3 At 0.1 mM, bpV(phen) inhibits SH2 domain-containing inositol 5’-phosphatase-2.4 Presumably by inhibiting insulin receptor kinase-associated PTPs, bpV(phen) activates the insulin receptor tyrosine kinase and promotes downstream signaling, including activation of PI3-kinase.5,6,7
