2,3-Dihydroxybenzoic acid is a natural phenol found in Phyllanthus acidus and in the aquatic fern Salvinia molesta. Hydroxyl radical attack upon salicylate leads to the generation of 2,3-dihydroxybenzoic acid (2,3-DHBA) and therefore can be used to assess hydroxyl radical formation both in vitro and in vivo. 2,3-Dihydroxybenzoic acid is a biological marker for the detection and quantification of hydroxyl radicals. 2,3-dihydroxybenzoic acid (DHB) has been safely administered to humans as an iron-chelating agent.

Sample Use Guides

In Vivo Use Guide

Rats were injected intravenously with doses of 2,3-Dihydroxybenzoic acid (DHB) including 1, 10,50, 100, and 150 mg/kg (pH 7.40; 300 to 380 mOsm/L) as well as 300 mg/kg (pH 7.40; 500 mOsm/L). The intravenous infusion of DHB 10 min before CVF administration reduced lung injury as measured by permeability index in a dose-dependent manner. The DHB at doses of 10, 50,100, 150, and 300 mg/kg was associated with a 33, 45, 48, 63, and 78% reduction in lung injury, respectively.

Route of Administration: Intravenous

In Vitro Use Guide

2,3-Dihydroxybenzoic acid potentiates PMN phagocytosis of opsonized lipopolysaccharide-coated PO droplets by 53% to 45% and chemotaxis by 36% to 10% at 10-3M and 10-4M concentrations, respectively.
