- The inhibitory effect of various anti-inflammatory drugs on the xanthine oxidase derived depolymerization of hyaluronic acid was studied. The depolymerization was assayed by repeated viscosity measurements. By using a low xanthine oxidase activity, the decrease in viscosity with time followed first order reaction kinetics and was therefore suitable for kinetic analysis. The xanthine oxidase activity was monitored by assay of O2-consumption with a Clark-electrode and by assay of urate production. We present evidence that salicylic, acetylsalicylic, gentisic and azodisalicylic acid and sulfasalazine inhibit the production of oxygen-derived free radicals by xanthine oxidase. We found that sulfapyridine, 5-aminosalicylic acid, allopurinol, mannitol, glucuronic acid and N-acetylglucosamine in addition to the earlier studied drugs, paracetamol, ibuprofen, benoxaprofen and gentisic acid exert their effect via scavenging of free radicals. These drugs had very little effect on the enzyme activity.
