| Application: | (−)-Epigallocatechin gallate has been used as: • a potential neuroprotective agent to test its protective effect against spinal cord injury and blood-spinal cord barrier (BSCB) leakage • an effective antioxidant against light-induced photoreceptor degeneration in mice retina • an antioxidant in retinitis pigmentosa (RP) and reduces oxidative damage and changes circadian rhythms in pigmented heterozygous P23H rat • to test its reversal effect on Diastolic dysfunction in restrictive cardiomyopathy (RCM) mice • an anti-cancer agent in colorectal cancer in mice |
| Biochem/physiol Actions: | (−)-Epigallocatechin gallate (EGCG) comprises eight -hydroxyl (OH) groups that determine its high antioxidant property. Other than being an efficient free oxygen radical scavenger, it also acts as a good chelating agent and a modulator of important transcription factors, namely nuclear factor-kappa β (NF-kβ). EGEC is proven to be an efficient anti-obesity agent by increasing energy expenditure, fat oxidation, and lowering appetite in humans. EGCG also acts as an anti-inflammatory and neuroprotective agent in the initial stages of ischemia and spinal cord injury. It reduces caveolin-1 expression, maintaining blood-brain barrier integrity and downregulating pro-inflammatory cytokines. |
| General description: | (−)-Epigallocatechin gallate, is a bioactive component of green tea accounting for 50-80% of the total catechin content. |
