inhibition assay. Among the tested compounds, derivatives 4h, 6e, 7a, 7e, and 9 showed more potent anti-inflammatory and analgesic activities than the reference drug celecoxib. On the basis of their higher activities in the in vivo studies compared with celecoxib, the five compounds 4h, 6e, 7a, 7e and 9 were selected to test their inhibitory activities against ovine COX-1/2 using an in vitro cyclooxygenase
报道了一组1,3,5-三取代吡唑啉的设计,合成和药理活性。已经基于IR,MS,1 H NMR和13 C NMR光谱分析确定了合成化合物的化学结构。体内评估了合成的1,3,5-三取代吡唑啉衍生物的抗炎,镇痛活性,体外评估了COX-1 / 2抑制作用。在测试的化合物中,衍生物4h,6e,7a,7e和9与参考药物塞来昔布相比,具有更强的抗炎和镇痛作用。基于它们在体内研究中比塞来昔布更高的活性,选择了五种化合物4h,6e,7a,7e和9进行体外环氧合酶抑制试验,以测试其对绵羊COX-1 / 2的抑制活性。将化合物7a,7e和9对接到COX-2结合位点的研究表明,其与选择性COX-2抑制剂SC-558的结合方式相似。
