(–)-Epigallocatechin gallate (EGCG) is a phenol that has been found in a variety of plants including green and black tea plants and has diverse biological activities.1,2,3,4,5,6 It is lytic against T. cruzi amastigotes, with a 50% bactericidal concentration (MBC50) value of 0.53 pM.1 ECGC decreases oxidation of deoxyguanosine and tyrosine nitration (IC50s = 0.25 and 0.11 mM, respectively) and inhibits macrophage-mediated LDL oxidation in vitro.7,3 EGCG increases LDL receptor binding activity and lowers cholesterol levels in HepG2 cells via increased cholesterol efflux.4 It inhibits heregulin-β1-induced activation of ErbB2 and ErbB3 as well as migration and invasion of MCF-7 breast cancer cells.5 In vivo, EGCG reduces food intake and body weight, serum levels of insulin, leptin, testosterone, and growth hormone, and the size of the ventral prostate, testis, liver, and spleen in male Sprague Dawley, lean Zucker, and obese Zucker rats when administered at doses of 82, 81, and 92 mg/kg, respectively.6
