  Heteroaromatic analogues of 1,5-diarylpyrazole class as anti-inflammatory agents

  摘要：

  A novel series of heteroaromatic analogues of known anti-inflammatory (AI) drug celecoxib replacing the benzenesulfonamide moiety with 6-sulfonamidobenzothiazol-2-yl moiety was synthesized. Regioselective synthesis of the target compounds 2a-i having 1,5-diaryl relationship was achieved by exploring reaction conditions. All the newly synthesized compounds (2a-i and 8) were screened for their in vivo AI activity using carrageenan-induced rat paw edema assay. Five compounds (2c-f and 2i) were found to possess good AI activity (a parts per thousand yen60% inhibition), 3 h after the carrageenan injection when compared to that of standard drug indomethacin (78%), whereas the remaining four compounds (2a-b and 2g-h) with 1,5-diaryl relationship have shown moderate activity with 49-56% inhibition after 3 h. However, pyrazole 8 having 1,3-diaryl relationship failed to show appreciable AI activity.
