Soluble Cocrystals of the Xanthine Oxidase Inhibitor Febuxostat
, 2013The synthesis and physicochemical characterization of febuxostat (FEB) cocrystals, a xanthine oxidase inhibitor, with pharmaceutically acceptable coformers, such as urea (URE), acetamide (ACT), nicotinamide (NIC), p-aminobenzoic acid (PABA), and ...

Inhibition of xanthine oxidase by pterins
Free Radical Research, 1998The effect of a panel of pterins on xanthine oxidase was investigated by measuring formation of urate from xanthine as well as formazan production from nitroblue tetrazolium. The pterin derivatives, depending on their chemical structure, decreased urate as well as formazan generation: 200 microM neopterin and biopterin suppressed urate formation (90 ...

Fluorometric assay for xanthine oxidase
Analytical Biochemistry, 1967Abstract It has been shown that the fluorometric assay for xanthine oxidase, in which 2-amino-4-hydroxypteridine (AHP) is oxidized to a fluorescent product, is not valid when applied to fresh extracts of rat liver. The reaction rate is not proportional to the amount of enzyme preparation in the range of substrate and tissue concentration recommended ...

Serum xanthine oxidase in jaundice
Clinica Chimica Acta, 1975Serum xanthine oxidase activity was measured by a radiochemical method in 137 consecutive patients with jaundice of varying etiology and in 40 non-jaundiced patients with liver or other disease. Serum xanthine oxidase was markedly increased, up to 50 times the upper normal limit (mean + 2 S.D.), in 32 out of 34 patients with infectious hepatitis.
