EGCG

Category: flavonoid

Aliases: Epigallocatechin gallate, (-)-Epigallocatechin-3-gallate

Pharmacological Mechanism

Flavan-3-ol gallate ester — the dominant green-tea polyphenol. DNMT1 inhibitor (epigenetic demethylation), 20S proteasome inhibitor (preclinical antineoplastic), COMT inhibitor (extends [[catecholamine_synthesis]] action — rationale for combined fat-oxidation protocols with [[caffeine]]). Potent aqueous-phase antioxidant. Strongest iron-chelator among tea polyphenols (relevant for Fe²⁺ bioavailability reduction).
