體外研究 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). Methyl gallate, in a concentration of 100 mM, could alleviate lipid peroxidation of the cells exposed to a short-term H 2 O 2 treatment. In addition, Methyl gallate-treated cells could prevent intracellular glutathione (GSH) from being depleted following an exposure of H 2 O 2 (8.0 mM) for a 3 h period. 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.
