comparable COX-2 selectivity to valdecoxib, while it was more selective than celecoxib but less selective than rofecoxib. The potential anti-inflammatory and antinociceptive activities of compounds 7a, 8a, and 8d were evaluated in vivo, where they showed a very good activity against both carrageenan-induced hyperalgesia and edema in the rat paw test. In the abdominal constriction test compound 7a, 8a, and
合成了一系列取代的1,5-二芳基吡咯-3-烷氧基乙基醚(6、7和8),目的是评估先前报道的1,5-二芳基吡咯衍生物(5)是否取代了乙酸酯具有烷氧基乙基的部分仍可产生新的,高选择性和有效的COX-2抑制剂。在体外细胞培养测定中,所有化合物均被证明是有效的选择性COX-2抑制剂。在人全血(HWB)分析中,化合物8a对valdecoxib具有相当的COX-2选择性,而比celecoxib更具选择性,但与rofecoxib相比选择性较低。在体内评估了化合物7a,8a和8d的潜在抗炎和镇痛活性,在鼠爪试验中,它们对角叉菜胶引起的痛觉过敏和浮肿均显示出非常好的活性。在腹部收缩试验中,化合物7a,8a和8d能够以统计学上显着的方式减少扭曲的次数。此外,这些化合物的亲和力数据已通过酶对接模拟,通过与Autoxock 3.0.5,GRID 21和MacroModel 8.5结合使用的复合物软件包,与COX-
