The antifolate activity of tea catechins.
A naturally occurring gallated polyphenol isolated from green tea leaves, (-)-epigallocatechin gallate (EGCG), has been shown to be an inhibitor of dihydrofolate reductase (DHFR) activity in vitro at concentrations found in the serum and tissues of green tea drinkers (0.1-1.0 micromol/L). These data provide the first evidence that the prophylactic effect of green tea drinking on certain forms o...
متن کاملCardioprotective effects of tea and its catechins
Tea is rich in polyphenolic catechins which are beneficial to health. There have been evidences suggesting that habitual tea consumption may reduce the risk of cardiovascular disease (CVD). Intake of tea or catechins isolated from tea was shown to inhibit the development of CVD in population studies and in animal models. Many possible pathways and mechanisms were investigated. There have been e...
متن کاملCancer Preventive Activities of Tea Catechins.
Catechins are widely occurring in our diet and beverages. The cancer-preventive activities of catechins have been extensively studied. Of these, (-)-epigallocatechin-3-gallate (EGCG), the principal catechin in green tea, has received the most attention. The inhibitory activities of tea catechins against carcinogenesis and cancer cell growth have been demonstrated in a large number of laboratory...
متن کاملProoxidative activities of tea catechins in the presence of Cu2+.
The ability of various tea catechins to generate H2O2 and the hydroxyl radical in the presence of the Cu2+ ion was investigated and compared with the effect of iron ions. The presence of Cu2+ accelerated the generation of H2O2 by EGC, while EGCg with Cu2+ generated a little H2O2. The presence of iron ions inhibited the generation of H2O2 by EGC. EGC and EC with Cu2+ generated the hydroxyl radic...
متن کاملChemopreventive Potential of Green Tea Catechins in Hepatocellular Carcinoma
Hepatocellular carcinoma (HCC), which is a common malignancy worldwide, usually develops in a cirrhotic liver due to hepatitis virus infection. Metabolic syndrome, which is frequently complicated by obesity and diabetes mellitus, is also a critical risk factor for liver carcinogenesis. Green tea catechins (GTCs) may possess potent anticancer and chemopreventive properties for a number of differ...
