Xanthine oxidase (XO) is the enzyme responsible for the catabolism of purines and their conversion into uric acid. CNS stimulant, smooth muscle relaxation, diuresis, and cerebral vasoconstriction. Native xanthine oxidase from buttermilk. Thus, XO inhibitors suppress hydrogen peroxide production while also reducing uric acid synthesis. Spiekermann showed, that the xanthine oxidase is also located in the vessel wall [4]. Xanthine oxidase (XO) converts hypoxanthine to xanthine, and xanthine to uric acid. For example, it efficiently converts 1-methylxanthine (a metabolite of caffeine) to 1-methyluric acid, but has little activity on 3-methylxanthine. However, severe side effects of allopurinol may occur in pat … For more than 50 years the only XO inhibitor drug available on the market was the purine analogue allopurinol.

Res Commun Mol Pathol Pharmacol 1999 ;104: 307 - 19 . XO produces uric acid and hydrogen peroxide from xanthine or hypoxanthine. Catalysis is initiated by base-assisted nucleophilic attack of the equatorial Mo-OH on the C-8 carbon of xanthine with concomitant hydride transfer from C-8 to Mo=S, which simultaneously results in reduction of Mo(VI) to Mo(IV). Deposition of crystals of the catalytic product uric acid or its monosodium salt in human joints with accompanying joint inflammation is the major cause of gout. compounds in each the propolis were measured quantitatively.
