This paper presents a detailed review of methods of isolation, determination of xanthine oxidase activity, and the effect of plant extracts and their constituents on it. xanthine + H 2 O + O 2 ⇌ uric acid + H 2 O 2; Xanthine oxidase can also act on certain other purines, pterins, and aldehydes. 2017 Dec;32(1):345-354. doi: 10.1080/14756366.2016.1252758. Oral propolis had a hypouricemic effect 2 h after its These include the antimetabolite class of cancer drugs like azathioprine and 6-mercaptopurine, both of which are metabolized by xanthine oxidase. Thus, XO inhibitors suppress hydrogen peroxide production while also reducing uric acid synthesis. xanthine + H 2 O + O 2 ⇌ uric acid + H 2 O 2; Xanthine oxidase can also act on certain other purines, pterins, and aldehydes. Various dietary flavonoids were evaluated in vitro for their inhibitory effect on xanthine oxidase, which has been implicated in oxidative injury to tissue by ischemia-reperfusion.
