Synthesis and bioevaluation of 1-phenyl-pyrazole-4-carboxylic acid derivatives as potent xanthine oxidoreductase inhibitors

A diverse library of 1-phenyl-pyrazole-4-carboxylic acid derivatives were synthesized and evaluated for their inhibitory potency against xanthine oxidoreductase (XOR) in vitro and vivo, and the structure-activity relationship (SAR) analyses were also pres

Synthesis and structure - Activity relationships of 1-phenylpyrazoles as xanthine oxidase inhibitors

A series of 1-phenylpyrazoles was evaluated for inhibitory activity against xanthine oxidase in vitro. Of the compounds prepared, 1-(3-cyano-4-neopentyloxyphenyl)pyrazole-4-carboxylic acid (Y-700) had the most potent enzyme inhibition and displayed longer-lasting hypouricemic action than did allopurinol in a rat model of hyperuricemia induced by the uricase inhibitor potassium oxonate.
