The diversity-oriented synthesis of 1,2,4-triazols, 1,3,4-thiadiazols, and 1,3,4-selenadiazoles from N-tosylhydrazones was developed, and the reactions were general for a wide range of substrates, in which NH2CN, KOCN, KSCN, and KSeCN were used as odorless sources. Two different pathways were proposed, and N-tosylhydrazonoyl chlorides were formed in situ in the presence of NCS.

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 invitro COX-II inhibition assay. The compounds 6b and 6m showed most significant in-vivo antiinflammatory with 72.33 &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 Cyclooxygenase (COX-II) enzyme (PDB Id: 3PGH), therefore the compounds 6b and 6m are used as promising lead candidates for the support of drug development.
