Allgemeine Beschreibung
3,4-Dihydroxybenzoic acid is reported as dietery polyphenol. Antiviral activity of 3,4-dihydroxybenzoic acid (protocatechuic acid, PCA) against a virulent H9N2 strain in a mouse model is reported. Cytotoxic effects of PCA on 3 non-small cell lung cancer (NSCLC) cell lines, A549, H3255, and Calu-6 cell lines is reported. PCA is reported to prevent the carcinogenesis or antitumor growth in vivo. Signaling pathway involved in PCA-induced apoptosis in human gastric adenocarcinoma (AGS) cells is reported. The oxidation of 3,4-dihydroxybenzoic acid by H2O2 in aqueous/goethite slurry at varying operating conditions (catalyst load, temperature, pH, substrate and hydrogen peroxide starting concentration) is investigated.
Anwendung
3,4-Dihydroxybenzoic acid is suitable for use in a study to investigate the effect of 4-coumaric and 3,4-dihydroxybenzoic acid on the basal oxidative DNA damage of rat colonic mucosa in vivo. It may be used in the derivatization of chitosan resin.

3,4-Dihydroxybenzoic acid (protocatechuic acid, PCA) is discussed to represent antioxidative food components in a human diet rich in fruits and vegetables, and has been shown to prevent carcinogenesis or antitumor growth in vivo. However, the molecular mechanisms involved in chemopreventive

The oxidation by H2O2 of 3,4-dihydroxybenzoic acid (3,4-DHB) in aqueous/goethite slurry at varying operating conditions (catalyst load, temperature, pH, substrate and hydrogen peroxide starting concentration) is investigated. At adopted catalyst loads the observed kinetic developments are consistent with a non-radicalic
