A new series of thiadiazole linked pyrazole benzenesulfonamide derivatives were synthesized by the condensation of aldehydic pyrazole with aryl substituted thiadiazole amine followed by Schiff base reaction. The synthesized compounds (6a-o) were characterized by IR, NMR, and Mass spectral data, further evaluated their in-vivo anti-inflammatory, analgesic and in-vitro COX-II inhibition assay. The compounds 6b and 6m showed most significant in-vivo anti-inflammatory with 72.33 and 71.17% inhibition along analgesic activity having 67.89% and 71.37 % respectively. Their selectivity against COX-II enzyme with selectivity index 67.81 and 66.38 was established for 6b and 6m, which is compared with Celecoxib. During the gastric ulceration study, selected compounds couldn’t observed any ulcerogenic effect on gastric mucosa.The in-silico pharmacokinetic profile and molecular docking study exposed very good binding affinity towards the cycloxygenase (COX-II) enzyme (PDB Id: 3PGH), therefore the compounds 6b and 6m are used as promising lead candidates for the support of drug development.
