描述 | Methyl gallate is a plant phenolic with antioxidant, anticancer, and anti-inflammatory activities. 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)[3]. MG (Methyl gallate) effectively inhibited the growth of both promastigote (IC50 5.71 μM) and amastigote-like forms (EC50 5.39 μM), with much higher selectivity indexes than the reference drugs, being more benign towards J774A.1 macrophages than meglumine antimoniate and amphotericin B, at 1631- and 70.92-fold respectively, with respect to the promastigote form. Additionally, MG proved to be even more active against intracellular amastigotes of the parasite (EC50 4.24 μM). In addition, MG induced increased phagocytic capability, and lysosomal volume in macrophages; structural parameters of microbicidal activity[4]. 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[5]. 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[6]. |
