Xanthine oxidase (XO) is a complex metalloflavoprotein, overproduction of which usually leads to a pathological condition called Gout. XO inhibitors may prove to be promising antigout agents. Present investigation describes synthesis, characterization and evaluation of 26 thiazolo-pyrazolyl derivatives V(a-z) for XO inhibitory and free radical scavenging activities. Derivatives Vq, Vo and Vh showed most promising XO inhibitory and free radical scavenging activities on the basis of their IC(50) values ranging from (6.5-9 μM). Significant dock scores compared with Allopurinol have been figured out using molecular docking. Evaluation of Vq, Vo and Vh for both the activities for first time may provide a new approach for antigout research.
