Description

General description

(−)-Epigallocatechin is one of the main catechin compounds found in green tea and the most abundant one (~20%), with antioxidant properties.

Application

(−)-Epigallocatechin (EGC) has been used:

as a reference standard in high-performance liquid chromatography (HPLC) analysis
to analyze its inhibitory effect on α-amylase and α-glucosidase activity to control postprandial hyperglycemia in Diabetes mellitus
in cell viability assays to check its efficacy and protection against ferroptosis and iron toxicity in murine pancreatic β-cells
to evaluate its potential anti-inflammatory effects on long-term acute and chronic Pristen-induced arthritis
to treat pregnant and nursing mice, on in vitro angiogenesis, proliferation, and movement of endothelial cells
to evaluate its effect on pregnant and nursing mice spleen based on the number and localization of CD4⁺ (cluster of differentiation 4) and CD8⁺ cluster of differentiation 8) cells

Biochem/physiol Actions

(−)-Epigallocatechin (EGC) has proven to be an anti-cancer agent by its inhibitory effects on heregulin-b1 (HRG)-induced migration/invasion in MCF-7 human breast carcinoma cells. It has also shown strong antiviral activity against the herpes simplex virus.

Green tea polyphenol. Anticancer agent. Lower antioxidant activity than EGCG.

Inhibitory effect of (-)-epigallocatechin and (-)-epigallocatechin gallate against heregulin beta1-induced migration/invasion of the MCF-7 breast carcinoma cell line.

Yukihiro Kushima et al.

Biological & pharmaceutical bulletin, 32(5), 899-904 (2009-05-08)

Migration/invasion is involved in the multiple steps of metastasis, resulting in a poor prognosis of breast cancer. (-)-Epigallocatechin-3-gallate (EGCG) in green tea inhibits the metastasis of some cancer cell lines. Cell migration/invasion assays using Boyden chambers demonstrated that (-)-epigallocatechin (EGC)

Ferroptosis is a form of programmed cell death that is characterized by lipid peroxidation and is inducible by iron and the accumulation of reactive oxygen species (ROS). It is triggered by erastin but inhibited by antioxidants such as -tocopherol, -carotene
