抑制PTP(IC 50 = 4-25 µM)和PTEN(IC 50 = 14 nM)。胰岛素模拟物。增强PI3K / Akt信号传导,并可能防止心肌缺血再灌注损伤。在体外有活性。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.
