Related to the mechanism of action, the green tea polyphenols, as epicatechin gallates, were reported as a potent antiviral entry inhibitor capable of blocking the host's binding of glycoprotein CD4 cell with glycoprotein gp120 of HIV‐1 and hence, preventing the viral infection.[113] The antiviral activity of green tea catechins was suggested in previous studies against other enveloped viruses. The gene discussed is ART4; the disease is viral infectious disease.
