The new series of asymmetrical pyrazole curcumin analogues 4a–g were synthesized by using polyethylene glycol (PEG‐400) as a green reaction medium and evaluated for their in vivo analgesic and in vitro antioxidant (H2O2, DPPH, Ferrous reducing power and Nitric oxide scavenging activity) and anti‐inflammatory activities. All the compounds synthesized 4a–g showed the potential to demonstrate analgesic
使用聚乙二醇(PEG-400)作为绿色反应介质合成了新系列的不对称吡唑姜黄素类似物4a – g,并评估了它们的体内止痛和体外抗氧化剂(H 2 O 2,DPPH,亚铁还原能力和一氧化氮清除活性)和抗炎活性。与标准布洛芬相比,所有合成的4a – g化合物都具有显示镇痛活性的潜力。在测试的系列中,化合物4e和4b与标准丁基化羟基甲苯(BHT)相比,具有良好的过氧化氢清除活性。化合物4b,4d,4f和4g显示出良好的DPPH自由基清除活性。化合物4b,4c,4d,4e和4g表现出优异的亚铁还原能力,而所有化合物均表现出比标准抗坏血酸更好的一氧化氮清除能力。此外,还对所有合成化合物的体外抗炎活性进行了筛选。化合物4b,4d,4f与标准双氯芬酸钠相比,4g和4g具有良好的抗炎活性。
