Biological Activity

Description Gallic acid (3,4,5-Trihydroxybenzoic acid, Gallate, Benzoic acid), known as powerful antioxidants, is an organic acid found in a variety of foods and herbs.
In vitro

Gallic acid does not protect against H(2)O(2)-induced PC12 cell death. It reduced the viability of PC12 cells in a dose-dependent manner. Gallic acid also induces cleavage of poly (ADP-ribose) polymerase, which is strongly related to apoptosis in neurons. Gallic acid induces the phosphorylation of c-Jun N-terminal protein kinase (JNK) and the downregulation of Bcl-2 in PC12 cells. Gallic acid leads to a progressive reduction in the viability of vector-transfected PC12 cells, which is delayed in PC12 cells that overexpressed Bcl-2[2].

In vivo Gallic acid effectively protects rat erythrocytes. The antioxidant effect of the compound at the tested dosage in vivo was more prevalent than its prooxidative effects. Gallic acid has ameliorative effect on lipid peroxidation in vivo[1].

Protocol (from reference)

Cell Research:[2]
  • Cell lines: PC12 cells
  • Concentrations: 25 or 50 μM
  • Incubation Time: 24 h
  • Method: Cell viability is measured using the MTT assay. PC12 cells are incubated at 37◦C with H2O2 or gallic acid at different concentrations for 24 h with or without pretreatment with resveratrol. They are then treated with the MTT solution (final concentration, 1 mg/mL) for 2 h. The dark-blue formazan crystals that formed in intact cells are dissolved in DMSO, and the absorbance at 570 nm is measured using a micro-ELISA reader.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
