    Norwogonin Description
    Source: The roots of Scutellaria baicalensis Georgi
    Biological Activity or Inhibitors: 1. Norwogonin shows potent inhibitory activity toward VHR.
    Solvent: Chloroform, Dichloromethane, Ethyl Acetate, DMSO, Acetone, etc.
    Storage: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months(2-8C).

    Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20C. Generally, these will be useable for up to two weeks. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.

    Need more advice on solubility, usage and handling? Please email to: service@chemfaces.com

    After receiving: The packaging of the product may have turned upside down during transportation, resulting in the natural compounds adhering to the neck or cap of the vial. take the vial out of its packaging and gently shake to let the compounds fall to the bottom of the vial. for liquid products, centrifuge at 200-500 RPM to gather the liquid at the bottom of the vial. try to avoid loss or contamination during handling.
    Recently, ChemFaces products have been cited in many studies from excellent and top scientific journals

    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). 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. 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.
