Description
OverviewA cell-permeable, reversible, substrate competitive, plant polyphenol that acts as a specific protein tyrosine kinase inhibitor. Potently inhibits the tyrosine kinase activity of the EGF receptor (IC50 = 65 µM) and p60c-src (IC50 = 65 µM). The inhibition is competitive with respect to ATP and non-competitive with respect to the substrate. Butein is also a potent antioxidant and anti-inflammatory agent. Has been shown to inhibit glutathione reductase and rat liver glutathione-S-transferase (IC50 = 9 µM). Reported to activate sirtuins and promote the survival of eukaryotic cells.
