      Epigallocatechol Gallate(EGCG) is an antioxidant polyphenol flavonoid that inhibits telomerase and DNA methyltransferase. EGCG blocks the activation of EGF receptors and HER-2 receptors.;IC50 value:;Target: apoptosis inducer(-)-Epigallocatechin Gallate (EGCG) is a strong polyphenol catechin antioxidant found in green tea, with broad efficacy against many conditions generated from oxidative damage. Extensive oxidation of low density lipoproteins (LDL) is correlated to cardiovascular diseases, and EGCG is reported to strongly inhibit Cu(2+)-mediated oxidative modification of LDLs. The antiapoptotic proteins Bcl-2 and Bcl-x(L) are observed to suppress apoptosis and convey survival to heavily damaged and mutated cells, and EGCG (along with the other catechins) is shown to directly inhibit these proteins, reestablishing the normal apoptotic pathway in the cell. After treating with EGCG, the expressions of HES1 and Notch2 was obviously inhibited, this indicated that EGCG inhibited color MedChem Express HY-13653
