| | (-)-CATECHIN GALLATE Usage And Synthesis |
| Chemical Properties | White powder, soluble in organic solvents such as methanol, ethanol, DMSO, etc., derived from green tea. | | Uses | ()-Catechin gallate has been used:
- to examine the potency of catechins containing galloyl moiety in inhibiting the activity of human immunodeficiency virus-1 (HIV-1)integrase
- to analyze the anti-oxidant and anti-viral properties of Pseudopiptadenia contorta and the commercial quebracho extracts in a herpes simplex virus type 1 strain, resistant to acyclovir
- to study the effects of polyphenols on the biochemistry of human spermatozoa and the associated limitations of their use in gamete preservation
| | Uses | A major component of green tea, is a dual phosphoinositide-3-kinase/mTOR inhibitor. | | Definition | ChEBI: (-)-catechin-3-O-gallate is a gallate ester obtained by formal condensation of the carboxy group of gallic acid with the (3R)-hydroxy group of (-)-catechin. It has a role as a metabolite. It is a gallate ester, a polyphenol and a member of flavans. It is functionally related to a (-)-catechin and a gallic acid. It is an enantiomer of a (+)-catechin-3-O-gallate. | | General Description | ()-Catechin gallate belongs to a class of polyphenol compounds that are formed when catechins in green tea undergo epimerization on heat treatment. It is a naturally occurring flavanol catechin having a galloyl moiety. | | Biochem/physiol Actions | Antioxidant constituent of green tea. At μM concentrations, it inhibits VEGF-induced tyrosine phosphorylation. It also inhibits aromatase activity, an enzyme that converts androgens to estrogen and is thought to play a role in the etiology of breast cancer. |
