IL1β levels in rat paws using the carrageenan inflammation model with the ELISA kit. Compound 8 has the best promising anti-inflammatory observations, antipyretic effect and long-lasting analgesic activity without ulcerogenic potential in addition to showing mutual inhibitory effects on all tested enzymes. Furthermore, a molecular docking study was introduced to recognize the binding interactions of the
从前体3-(4-甲氧基苯基)-1H-吡唑-4-甲醛( 1 )和3-(4-溴苯基)-1-乙基-1H-吡唑-4-甲醛( 2 )开始,合成了三取代的吡唑衍生物3-15 ,并评估了它们的抗炎、镇痛、解热和溃疡特性。衍生物3a、3b、6、8和11显示出有希望的抗炎观察结果,效力分别为 99.5, 100.3, 92.4, 77.1 和 103.1与参比药物比较,其对胃黏膜的解热作用和安全范围。基于获得的观察结果,使用带有 ELISA 试剂盒的角叉菜胶炎症模型,测定了衍生物3a、3b、6、8和11在大鼠爪子中的 COX-2、TNF- α、PGE2 和 IL1β水平。化合物8除了对所有测试的酶显示出相互抑制作用外,它还具有最有希望的抗炎观察、解热作用和持久的镇痛活性,没有潜在的溃疡形成。此外,引入了分子对接研究,以识别最有效的候选物3a、3b、6、8和11与 COX-2 和 TNF- α的活性位点的结合
