Opis

Opis ogólny

A 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 p60^c-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 (GSH-RD) and rat liver glutathione S-transferase (GST; IC₅₀ = 9 µM). Reported to activate sirtuins and promote the survival of eukaryotic cells.
