Lactoperoxidase Inhibition of Celecoxib Derivatives Containing the Pyrazole Linked‐Sulfonamide Moiety: Antioxidant Capacity, Antimicrobial Activity, and Molecular Docking Studies

Celecoxib derivatives that contain the pyrazole-linked sulfonamide moiety were synthesized, and the in vitro inhibitory impacts of the aforesaid compounds against the lactoperoxidase (LPO) enzyme were researched. To this end, LPO was purified using the affinity chromatography technique with a yield of 12.63% (319.23-fold). The results showed that the aromatic pyrazole compound (compound 1) containing 2,3-dimethoxyphenyl functional groups was the most effective LPO inhibitor with a K
