A novel series of 1-substituted aminomethyl-3-[1-(4-isobutylphenyl)ethyl]-4-(3-aryl-4-sydnonylidene) amino-1,2,4-triazol-5-thiones (9), was prepared from the 3-[1-(4-isobutylphenyl)ethyl]-4-(3-aryl-4-sydnonylidene) amino 5-mercapto-1,2,4-triazoles (8) by aminomethylation with formaldehyde and secondary amine. The structures of Schiff bases (8) and Mannich bases (9) were characterized on the basis of
一系列新的1-取代的氨基甲基-3- [1-(4-异丁基苯基)乙基] -4-(3-芳基-4-亚磺酰基)氨基-1,2,4-三唑-5-硫酮(9),由3- [1-(4-异丁基苯基)乙基] -4-(3-芳基-4-亚磺酰基)氨基5-巯基-1,2,4-三唑(8)通过甲醛和仲胺的氨甲基化反应制备。基于红外,核磁共振,质谱数据和元素分析对席夫碱(8)和曼尼希碱(9)的结构进行了表征。筛选新合成的化合物的抗炎和镇痛活性。曼尼希基地(9)带有哌啶和吗啉残留物显示出有希望的消炎和镇痛活性。
