Background

Gentisic acid is a benzoic acid that has been found in Gentiana and an active metabolite of aspirin with diverse biological activities.^1,2,3,4,5 It decreases radiation-induced production of thiobarbituric acid reactive substances (TBARS), hydrogen peroxide, and protein carbonyls, increases superoxide dismutase activity, and prevents hemolysis in isolated human erythrocytes when used at concentrations ranging from 5 to 100 μM.¹ Gentisic acid (1-10 μM) inhibits LDL oxidation and formation of cholesterol ester hydroperoxides in isolated human plasma.² It induces relaxation of isolated guinea pig trachea (EC₅₀ = 20 μM), an effect that is reduced by the large-conductance calcium-activated potassium channel blocker charybdotoxin .³ Gentisic acid (10 and 100 mg/kg) reduces cardiac hypertrophy and fibrosis and pulmonary remodeling, suppresses the renin-angiotensin-aldosterone system, and inhibits cardiac dysfunction in a mouse model of transverse aortic constriction-induced cardiac hypertrophy.⁴ It also prevents cardiovascular collapse and lactic acidemia in a canine model of P. aeruginosa-induced septic shock.⁵
