these compounds were evaluated by using the adjuvant arthritis and Randall-Selitto assays in rats, and the structure-activity relationships were studied. The optimal compound was 3-(difluoromethyl)-1-(4-methoxyphenyl)-5-[4-(methylsulfinyl)phenyl]pyraz ole (10) with oral ED50 values of 0.31 and 2.6 mg/kg on adjuvant-induced arthritis and carrageenin-induced foot edema, respectively. Compound 10 showed
制备了一系列带有亲水取代基的新型1,5-二苯基吡唑衍生物。通过在大鼠中使用佐剂关节炎和Randall-Selitto试验评估了这些化合物的抗炎和镇痛活性,并研究了其构效关系。最佳化合物为3-(二氟甲基)-1-(4-甲氧基苯基)-5- [4-(甲基亚磺酰基)苯基]吡唑(10),口服佐剂诱发的关节炎时的ED50值为0.31和2.6 mg / kg。角叉菜胶引起的足部水肿。在Randall-Selitto分析中,化合物10不仅对发炎的爪显示镇痛活性,而且还对正常爪显示镇痛活性(分别为ED30 = 0.55和1.8 mg / kg),此外,化合物10在尾巴捏制试验中有效(ED50 = 21毫克/千克)与吗啡类似。
