General description

One of the main polyphenolic constituents of green tea that exhibits potent antitumor, anti-inflammatory, and antioxidant properties. Arrests cell cycling at G₀/G₁ phase and induces apoptosis in a dose-dependent manner. Shown to inhibit PMA-induced skin thickening and to activate of protein kinase C. Also activates ornithine decarboxylase and interleukin-1α mRNA and protein expression. Acts as an inhibitor of inducible nitric oxide synthase (iNOS) gene expression and enzyme activity. Also blocks peroxynitrite-mediated formation of 8-oxodeoxyguanosine and 3-nitrotyrosine. Strongly and directly inhibits telomerase in cell-free systems and in cancer cell lines. An inhibitor of Dnmt1 (IC₅₀ = 210-470 nM). Acts as a selective and noncompetitive inhibitor of HAT activities (IC₅₀ = 30, 50, 60 and 70 µM for p300, CBP, PCAF and TIP60) with minimal effects on HDAC, SIRT and HMTase.
