Methyl gallate is a plant phenolic with antioxidant, anticancer, and anti-inflammatory activities. Methyl gallate also shows bacterial inhibition activity. Methyl gallate also has anti-HIV-1 and HIV-1 enzyme inhibitory activities.

Bacterial^[1]

The growth of A. viscosus is inhibited completely by a low dose of Methyl gallate (MIC=1 mg/mL). S. mutans and . sobrinus show intermediate sensitivity to Methyl gallate (MIC=2-4 mg/mL), whereas the growth of Lactobacillus spp. is inhibited completely at a relatively high concentration (MIC=8 mg/mL)^[1]. Methyl gallate, in a concentration of 100 mM, could alleviate lipid peroxidation of the cells exposed to a short-term H₂O₂ treatment. In addition, Methyl gallate-treated cells could prevent intracellular glutathione (GSH) from being depleted following an exposure of H₂O₂ (8.0 mM) for a 3 h period^[2]. Methyl gallate inhibits Treg cell-suppressive effects on effector CD4+ T cells and Treg migration toward tumor environment. Furthermore, forkhead box P3 (Foxp3) expression is also significantly decreased by methyl gallate^[3].
