Definition
ChEBI: (-)-gallocatechin gallate is a gallate ester obtained by formal condensation of the carboxy group of gallic acid with the (3R)-hydroxy group of (-)-gallocatechin. A natural product found in found in green tea. It has a role as an EC 3.4.22.69 (SARS coronavirus main proteinase) inhibitor, a human xenobiotic metabolite, an antineoplastic agent and a plant metabolite. It is a gallate ester, a polyphenol and a catechin. It is functionally related to a (-)-gallocatechin and a gallic acid. It is an enantiomer of a (+)-gallocatechin gallate.
