Product Overview
Description:
(−)-Catechin gallate is a natural polyphenolic catechin constituent derived from green tea that exhibits distinct anti-proliferative, metabolic, and anti-parasitic activities. It curtails breast cancer cell expansion, impairs growth factor-stimulated receptor phosphorylation in endothelial cells, functions as a competitive inhibitor of GLUT4 glucose transporters, and demonstrates potent lytic activity against protozoan amastigotes.
