  Design, Synthesis, and Pharmacological Evaluation of Pyridinic Analogues of Nimesulide as Cyclooxygenase-2 Selective Inhibitors

  摘要：

  In this study, we report the synthesis and pharmacological evaluation of original pyridinic sulfonamides related to nimesulide, a cyclooxygenase-2 (COX-2) preferential inhibitor widely used as an anti-inflammatory agent. These original pyridinic derivatives were synthesized in three steps starting from the condensation of 3-bromo-4-nitropyridine N-oxide with appropriately substituted phenols, thiophenols, or anilines followed by a reduction of the nitro moiety into the corresponding aminopyridine, which was finally condensed with alkane- or trifluoromethanesulfonyl chloride to obtain the corresponding sulfonamides. The pK(a) determinations demonstrated that the major ionic form present in solution at physiological pH depends on the nature of the sulfonamide moiety subsituent. Indeed, alkanesulfonamides were mainly present as zwitterionic molecules while trifluoromethanesulfonamides, more acidic derivatives, were mainly present as anionic molecules. The in vitro pharmacological evaluation of the synthesized compounds against COX-1 and COX-2 was performed in a human whole blood model. Results obtained demonstrated that most of alkanesulfonamide derivatives displayed a COX-2 preferential inhibition with selectivity ratio values (IC50(COX-1)/IC50(COX-2)) up to 7.92 (celecoxib displaying a ratio value of 7.46 in the same test). On the other hand, trifluoromethanesulfonamide derivatives displayed weaker selectivity ratios although they exhibited IC50 values against COX-2 up to 0.09 muM (celecoxib IC50 against COX-2: 0.35 muM). Finally, in vivo evaluation of selected compounds showed that they exhibited anti-inflammatory properties similar to that of nimesulide when tested in a carrageenan-induced rat paw oedema model.

  Nonsteroidal anti-inflammatory drugs (NSAIDs) represent one of the most prescribed medications, although the chronic use of such pharmacological agents is commonly associated with numerous side effects. The demonstration that the use of COX-2 selective or preferential inhibitors is associated with a better tolerability opened new horizons in the search of safer drugs for the management of inflammation. In the present study, we report the synthesis and the pharmacological evaluation of pyridine analogues of nimesulide, a COX-2 preferential inhibitor. The cyclooxygenases (COXs) inhibitory activities were evaluated in vitro using a human whole blood model. According to the in vitro results, a selection of compounds exhibiting moderate to high COX-2/COX-1 selectivity ratio (from weak COX-2 preferential inhibitors to compounds displaying a celecoxib-like selectivity profile) were further evaluated in vivo in a model of A carrageenan-induced pleurisy in rats. Some of the selected compounds displayed similar or improved anti-inflammatory properties when compared to nimesulide and celecoxib.
