Oxonic Acid (potassium salt)

Oxonic acid is a uricase inhibitor that prevents metabolism and excretion of uric acid (Cay-16219) and induces embryotoxicity and nephrotoxicity in rats. It is a component of S-1, a mixture containing a prodrug of the antitumor agent 5-fluorouracil (5-FU, Cay-14416), that suppresses the gastrointestinal toxicity of 5-FU without inhibiting its antitumor activity in rats. Formulations containing oxonic acid have been used to treat gastric, pancreatic, lung, head, neck, and breast carcinomas.Formal Name: 1,4,5,6-tetrahydro-4,6-dioxo-1,3,5-triazine-2-carboxylic acid, monopotassium salt.
