In Vitro |
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].

In Vivo:
Select the appropriate dissolution method based on your experimental animal and administration route.
For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline Solubility: ≥ 2.5 mg/mL (13.58 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL. Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
-
Protocol 2
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline) Solubility: ≥ 2.5 mg/mL (13.58 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
-
Protocol 3
Add each solvent one by one: 10% DMSO 90% Corn Oil Solubility: ≥ 2.5 mg/mL (13.58 mM); Clear solution
This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully. Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.
