drugs. Some compounds, such 4a and 11b exhibited significant anti-inflammatory activity with gastric ulcerogenic potential less than that of ibuprofen. Results of the analgesic activity showed that compounds possessing good anti-inflammatory activity showed also good analgesic. Substitution of pyrazole ring with at least one aryl moiety was found to be essential for anti-inflammatory and analgesic activities
摘要设计和一些吡唑衍生物的合成4 - 11预期的抗炎和镇痛活性。另外,使用(MOE)将测试的化合物对接至环加氧酶II中以合理化所获得的生物学结果及其作用机理。通过光谱和元素分析阐明了新化合物的结构。使用角叉菜胶诱导的大鼠爪水肿方法评估所有新合成的化合物的抗炎活性。目标化合物的镇痛活性使用p还评估了-苯醌扭曲诱导的方法及其诱导胃毒性的能力。结果表明,与作为参考药物的布洛芬和塞来昔布相比,新合成的化合物显示出弱至良好的活性。某些化合物(例如4a和11b)显示出显着的抗炎活性,胃溃疡的发生潜力低于布洛芬。镇痛作用的结果表明,具有良好抗炎活性的化合物也显示出良好的镇痛作用。发现吡唑环被至少一个芳基部分取代对于抗炎和镇痛活性是必不可少的。游离的(吡唑环的)NH和/或酸性基团(COOH)将改善抗炎活性。 图形概要
