Cytoprotective effect of the enzyme-mediated polygallic acid on fibroblast cells under exposure of UV-irradiation

The poly(gallic acid), produced by laccase-mediated oxidation of gallic acid in aqueous media (pH 5.5) to attain a novel material with well-defined molecular structure and high water solubility (500 mg/mL at 25 °C), has been investigated to understand its potential biological activities. In this regard, a biomedical approach based on cytoprotective effect on human fibroblast cells exposed to UV-irradiation in the presence of the polymer has been...
