1131828-2	1975	These data suggest that this alteration in antitumor activity results from a decreased catabolism of preformed systemic purines by allopurinol, a potent inhibitor of xanthine oxidase.	Purines	120-127	xanthine dehydrogenase	Mus musculus	166-182	
6509051-1	1984	Using mouse small intestine brush-border membrane vesicles virtually free of xanthine oxidase (EC 1.2.3.2) and free of uricase (EC 1.7.3.3) the uptake of the purines uric acid, xanthine and hypoxanthine have been studied.	Purines	158-165	xanthine dehydrogenase	Mus musculus	77-93	
7835888-1	1994	Xanthine dehydrogenase (XD) is a key enzyme in the catabolism of purines.	Purines	65-72	xanthine dehydrogenase	Mus musculus	0-22	
7835888-1	1994	Xanthine dehydrogenase (XD) is a key enzyme in the catabolism of purines.	Purines	65-72	xanthine dehydrogenase	Mus musculus	24-26	
25831123-1	2015	BACKGROUND: Xanthine oxidoreductase (XOR) is involved in oxidative metabolism of purines and is a source of reactive oxygen species (ROS).	Purines	81-88	xanthine dehydrogenase	Mus musculus	12-35	
25831123-1	2015	BACKGROUND: Xanthine oxidoreductase (XOR) is involved in oxidative metabolism of purines and is a source of reactive oxygen species (ROS).	Purines	81-88	xanthine dehydrogenase	Mus musculus	37-40	
25449036-3	2015	Cells contain high levels of intracellular uric acid, which is produced when purines are oxidized by the enzyme xanthine oxidase.	Purines	77-84	xanthine dehydrogenase	Mus musculus	112-128	
23877847-1	2013	BACKGROUND: Inhibition of xanthine oxidase by allopurinol increases hypoxanthine and xanthine, which are converted to purines, including the inhibitory neuromodulator adenosine.	Purines	118-125	xanthine dehydrogenase	Mus musculus	26-42
