In present work the 4-formyl pyrazole (1) were treated with 4-morpholinoacetophene (2) in the presence of aqueous KOH to give Chalcones (3). The chalcones are subjected to react with malononitrile using sodium methoxide as a base in methanol to give pyridine-3-carbonitriles (4). The synthesized chalcone and pyridine-3-carbonitrile derivatives were subjected for study of their anti-inflammatory activity by the well known carrageenan induced rat paw edema method. The products 3a, 3e and 4e exhibited good activity as compared with standard diclofenac drug. The formation of all compounds was established by the spectral techniques such as Infra Red, 1H-NMR and mass.
在本研究中,4-甲酰基吡唑(1)与 4-吗啉基乙炔(2)在 KOH 水溶液中进行处理,得到查耳酮(3)。在甲醇中以甲醇钠为碱与丙二腈反应,得到吡啶-3-甲腈(4)。合成的查尔酮和吡啶-3-甲腈衍生物被用于研究它们的抗炎活性,研究采用了众所周知的卡拉胶诱导大鼠爪水肿法。与标准双氯芬酸药物相比,产品 3a、3e 和 4e 表现出良好的活性。通过红外光谱、1H-NMR 和质量等光谱技术确定了所有化合物的形成。
