A regioselective synthesis of 2,3-disubstituted tetrahydro-2H-indazols, mediated by alpha-zirconium sulfopherylphosphonate-methanephosphonate, was reported. Docking studies into the catalytic site of COX-2 were used to identify potential antiinflammatory lead compounds. Two lead derivatives were chosen endowed with good binding energies and good ADME profiling. The biological in vivo evaluation of these compounds in two different experimental models (Freund's adjuvant-induced arthritis and carrageenan-induced oedema) proved the presence of anti-inflammatory activity. Noteworthy, both compounds evidenced the lack of any gastric injury even at high doses in gastric ulcerogenic assays. (c) 2007 Elsevier Ltd. All rights reserved.
