xanthine ribonucleotide
1.PEROXIDATION EFFECTS ON LIPOSOME OF ACTIVE OXYGEN SPECIES PRODUCED BY THE SYSTEM OF ADP-FeCl_3-XANTHINE-XANTHINE OXIDASE
2.METHODS :①Studies on xanthine oxidase(XO) inhibitory activity of Qi salt in vitro ;
4.Determination of hypoxanthine and xanthine in fish by the coupled reaction of enzyme (fluorometric method)
6.Objective To explore the effect of propofol on xanthine oxidase(XO) activity during hepatic ischemia-reperfusion injury (HIRI).
7.ESR spectrum of hypoxanthine-xanthine oxidase and Fe ++ —H 2O 2 system were significantly reduced or disappear by NADH.
8.This paper describes a new method for determination of xanthine (Xa) at a poly (acridine orange)(POAO)modified electrode by 2.5th order differential voltammetry.
9.A novel technology to determine the activity of xanthine oxidase(XOD) through the chromogenic reaction of 4-aminoantipyrine(AAP),phenic acid(PA) and hydrogen peroxide(H_2O_2),which was produced via the oxidation of xanthine catalyzed by XOD,under the help of horseradish peroxidase(HRP) was(proposed).
10.Tea contains, in addition to caffeine, small amounts of two other methyl xanthines, theobromine and theophylline, 3,7 -dimethy1 and 1,3-dimethy1 xanthine, respectively.
