  Synthesis and Cyclooxygenase-2 Inhibiting Property of 1,5-Diarylpyrazoles with Substituted Benzenesulfonamide Moiety as Pharmacophore:  Preparation of Sodium Salt for Injectable Formulation^†

  摘要：

  A series of 1,5-diarylpyrazoles having a substituted benzenesulfonamide moiety as pharmacophore was synthesized and evaluated for cyclooxygenase (COX-1/COX-2) inhibitory activities. Through SAR and molecular modeling, it was found that fluorine substitution on the benzenesulfonamide moiety along with an electron-donating group at the 4-position of the 5-aryl ring yielded selectivity as well as potency for COX-2 inhibition in vitro. Among such compounds 3-fluoro-4-[5-(4-methoxyphenyl)-3-trifluoromethyl-1H-1-pyrazolyl]-1-benzenesulfonamide 3 displayed interesting pharmacokinetic properties along with antiinflammatory activity in vivo. Among the sodium salts tested in vivo, 10, the propionyl analogue of 3, showed excellent antiinflammatory activity and therefore represents a new lead structure for the development of injectable COX-2 specific inhibitors.
