Abstract
Therapeutically-active and pharmacologically-acceptable 1-amido-5-cyano-4(1H)-pyrimidinones and their pharmaceutically-acceptable acid addition salts inhibit xanthineoxidase and are useful as the active ingredient in medicaments for the treatment of gout. Such pyrimidinones are prepared by treating 2-(acyl) hydrazonomethyl-3-chloro or hydroxy-4-aza-2,4-pentadienenitriles with acid.
