these derivatives (6a–j) were evaluated for their anti-inflammatory and analgesic activities. Among the synthesized compounds 6j and 6i with CF3 group and 6d with Br group exhibited excellent anti-inflammatory activity, and the compound 6f with benzyloxyphenyl showed less anti-inflammatory activity when compared with the activity of standard reference, indomethacin. Further, these derivatives (6a–j)
从5-溴-1H-吡唑并[3,4-b]吡啶-3-甲醛(4)合成了一系列7-氮杂吲唑-查耳酮(6a–j)衍生物。对5-溴-1H-吡唑并[3,4-b]吡啶(3)进行Sommelet反应,得到5-溴-1H-吡唑并[3,4-b]吡啶--3-甲醛(4),在碱性介质中与不同的取代苯乙酮(5a–j)进行Claisen–Schmidt缩合反应,得到7-氮杂吲唑-查耳酮(6a–j)衍生物。这些化合物的特征在于其红外,质子核磁共振,13 C核磁共振和质谱数据。所有这些导数(6a–j)被评估其抗炎和镇痛活性。在合成的具有CF 3基团的化合物6j和6i和具有Br基团的6d中显示出优异的抗炎活性,与标准参比消炎痛相比,具有苄氧基苯基的化合物6f显示出较少的抗炎活性。此外,评估了这些衍生物(6a–j)的镇痛活性。其中,与标准药物双氯芬酸钠的活性相比,化合物6e,6d,6j和6i表现出优异的镇痛活性。
