Some novel Mannich base isatin derivatives were synthesized by reacting 1-(5-methyl-2-oxoindolin-3-ylidene)-4-(substitutedpyridin-2-yl)thiosemicarbazide with formaldehyde and several secondary amines. Their chemical structure was elucidated by means of spectral (FT-IR, 1H- and 13C-NMR and mass) analysis. Investigation of anti-inflammatory activity of synthesized compounds was done by carrageenan induced paw oedema method using diclofenac sodium as standard drug and analgesic activity was done by acetic acid induced writhing method. The synthesized compounds showed significant anti-inflammatory and analgesic activity.
通过将1-(5-甲基-2-氧代吲哚啉-3-亚基)-4-(取代吡啶-2-基)缩氨基脲与甲醛和多种二级胺反应,合成了一系列新型曼尼希碱吲哚衍生物。通过光谱(FT-IR、1H和13C-NMR及质谱)分析阐明了其化学结构。采用卡拉胶引起的足跛行法进行抗炎活性研究,以双氯芬酸钠为标准药物,并通过醋酸引起的扭体法进行镇痛活性研究。合成的化合物显示出显著的抗炎和镇痛活性。
