    Inhibition of VHR dual-specificity protein tyrosine phosphatase activity by flavonoids isolated from Scutellaria baicalensis: structure-activity relationships.[Pubmed: 12494330]
    Three flavonoids: Norwogonin, dihydroNorwogonin and baicalein, were isolated from the roots of Scutellaria baicalensis, as potential inhibitors of VHR dual-specificity protein tyrosine phosphatase (DS-PTPase).
    METHODS AND RESULTS:
    Norwogonin (IC 50 = 1.1 microM), dihydroNorwogonin (IC 50 = 2.9 microM) and baicalein (IC 50 = 2.4 microM) showed potent inhibitory activity toward VHR, but had no inhibitory activity against T-cell protein tyrosine phosphatase or serine/threonine protein phosphatase 1.
    CONCLUSIONS:
    From comparisons to the inhibitory activities of other similar flavonoids, it could be suggested that the presence of a hydroxy group in the B ring of flavonoids interferes with the inhibitory activity toward VHR DS-PTPase.
