Roles Classification
Chemical Role(s): radical scavenger
A role played by a substance that can react readily with, and thereby eliminate, radicals.
Biological Role(s): antimetabolite
A substance which is structurally similar to a metabolite but which competes with it or replaces it, and so prevents or reduces its normal utilization.
EC (xanthine oxidase) inhibitor
An EC 1.17.3.* (oxidoreductase acting on CH or CH2 with oxygen as acceptor) inhibitor that interferes with the action of xanthine oxidase (EC
Application(s): gout suppressant
A drug that increases uric acid excretion by the kidney (uricosuric drug), decreases uric acid production (antihyperuricemic), or alleviates the pain and inflammation of acute attacks of gout.
