  Synthesis and pharmacological evaluation of derivatives structurally related to nimesulide

  摘要：

  The present work reports the synthesis of a series of compounds structurally related to the antiinflammatory and antihistaminic agent nimesulide (I), in which the p-nitrophenyl moiety has been replaced by pyridine (1a-c) and pyridine N-oxide (2a-c). In addition, two compounds (3a, 4a) have been synthesized in which the p-nitro group of I was substituted by a cyano and a 1H-tetrazol-5-yl group, respectively. Representative 1a and 2a were also modified by replacing the methanesulfonamido group with an acetamido group (5a, 6a). The pharmacological evaluation of compounds 1-6 in comparison to I, indicates that such modifications are detrimental to the activity. Moreover 3a and 4a caused bronchoconstriction and hypotension, thus behaving as histaminic-like rather then antihistaminic agents.

  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.
