Xanthine 79-87 xanthine dehydrogenase Rattus norvegicus 0-3 15971422-2 2005 Nitrotyrosine is formed by nitration of tyrosine by reactive nitrogen species such as peroxynitrite, the formation of which may be enhanced by xanthine oxidoreductase (XOR), since it can generate nitric oxide from nitrite/nitrate, and superoxide during xanthine metabolism. Xanthine 143-151 xanthine dehydrogenase Rattus norvegicus 168-171 11246119-5 2001 Incubation of cytosolic fraction with xanthine oxidoreductase (XDh+XO) (XOR) cosubstrates (e.g. NAD+, hypoxanthine, xanthine, caffeine, theobromine, theophylline or 1,7-dimethylxanthine) significantly enhanced the biotransformation of ethanol to acetaldehyde. Xanthine 38-46 xanthine dehydrogenase Rattus norvegicus 63-66 11246119-5 2001 Incubation of cytosolic fraction with xanthine oxidoreductase (XDh+XO) (XOR) cosubstrates (e.g. NAD+, hypoxanthine, xanthine, caffeine, theobromine, theophylline or 1,7-dimethylxanthine) significantly enhanced the biotransformation of ethanol to acetaldehyde. Xanthine 38-46 xanthine dehydrogenase Rattus norvegicus 72-75 18375259-3 2008 With the supply of molecular oxygen upon reperfusion of ischemic tissues, xanthine oxidoreductase (XOR) metabolizes xanthine and hypoxanthine to uric acid and free radicals are generated. Xanthine 74-82 xanthine dehydrogenase Rattus norvegicus 99-102 17440754-6 2007 It was confirmed that, for the reducing substrate xanthine, rat liver XD is also a better O2*- source than XO. Xanthine 50-58 xanthine dehydrogenase Rattus norvegicus 70-72 9288448-10 1997 Ischemia-evoked increases in xanthine concentration were attenuated by inhibition of adenosine deaminase or xanthine oxidase/xanthine dehydrogenase. Xanthine 29-37 xanthine dehydrogenase Rattus norvegicus 125-147 9822451-4 1998 Xanthine oxidoreductase (XOR) oxidizes ATP metabolites hypoxanthine and xanthine to urate. Xanthine 59-67 xanthine dehydrogenase Rattus norvegicus 0-23 9822451-4 1998 Xanthine oxidoreductase (XOR) oxidizes ATP metabolites hypoxanthine and xanthine to urate. Xanthine 59-67 xanthine dehydrogenase Rattus norvegicus 25-28 33132325-8 2020 Furthermore, dotinurad, a URAT1 inhibitor, increased renal clearance of xanthine in rats treated with topiroxostat to inhibit XOR. Xanthine 72-80 xanthine dehydrogenase Rattus norvegicus 126-129 8903395-11 1996 The finding of this low percentage of xanthine oxidase further stresses that the main function of xanthine oxidoreductase in the liver is not the production of superoxide anion radicals and/or hydrogen peroxide but rather the metabolism of xanthine to uric acid, which can act as a potent antioxidant. Xanthine 38-46 xanthine dehydrogenase Rattus norvegicus 98-121 3162724-2 1988 The direct spectrophotometric measurement of the various forms of the xanthine-converting enzyme indicates that, in the fresh rat heart or after normoxic perfusion, there always is a basal level of 80% xanthine dehydrogenase and 20% of xanthine oxidase (15% irreversible and 5% reversible) that could contribute to the background production of free radicals. Xanthine 70-78 xanthine dehydrogenase Rattus norvegicus 202-224 6952874-1 1981 The course of the reaction sequence hypoxanthine leads to xanthine leads to uric acid, catalysed by the NAD+-dependent activity of xanthine oxidoreductase, was investigated under conditions either of immediate oxidation of the NADH formed or of NADH accumulation. Xanthine 40-48 xanthine dehydrogenase Rattus norvegicus 131-154 33132325-1 2020 Xanthine and hypoxanthine are intermediate metabolites of uric acid and a source of reactive oxidative species (ROS) by xanthine oxidoreductase (XOR), suggesting that facilitating their elimination is beneficial. Xanthine 0-8 xanthine dehydrogenase Rattus norvegicus 145-148 21105859-1 2011 As a precedent study for elucidating the mechanism of possible urinary bladder carcinogenesis due to xanthine crystals induced by FYX-051, a xanthine oxidoreductase inhibitor, we have determined the experimental conditions suitable for the 52-week simultaneous treatment with citrate in F344 rats. Xanthine 101-109 xanthine dehydrogenase Rattus norvegicus 141-164 24448833-0 2014 Xanthine crystals induced by topiroxostat, a xanthine oxidoreductase inhibitor, in rats, cause transitional cell tumors. Xanthine 0-8 xanthine dehydrogenase Rattus norvegicus 45-68 21077683-1 2010 Two contradictory models have been proposed for the binding mode of the substrate xanthine to and its activation mechanism by xanthine oxidoreductase.
