2-mercapto-6-phenylpyrimidine-4-carboxylic acid derivatives (7a‒c, 8a‒e, 9a‒e and 10a‒e) as novel xanthineoxidaseinhibitors were designed based on molecular docking, and synthesized by a new method using ketoenol acids and thiourea as the starting materials. In vitro activity assay indicated that most of the designed compounds displayed submicromolar inhibitory potency. Specifically, compound 9b had the most
In view of expanding the structure activity relationship of xanthineoxidaseinhibitors, a series of 3-oxo-6-aryl-2,3-dihydropyridazine-4-carbohydrazide/carboxylic acid derivatives were designed by molecular docking and synthesized. All the target compounds were evaluated for their in vitro XO inhibition by using febuxostat and allopurinol as the standard controls. Most of the hydrazide derivatives
