  • Synthesis, characterization and in vitro cytotoxic properties of some new Schiff and Mannich bases in Hep G2 cells
    作者:Dhanya Sunil、Arun M. Isloor、Prakash Shetty、B. Chandrakantha、K. Satyamoorthy
    DOI:10.1007/s00044-010-9433-z
    日期:2011.9
    Schiff bases, 3a, 3d, 3e, 3g and 3h showed dose dependent cytotoxic activity, 3a being the most potent with an IC50 value of 0.018 g/l comparable to the standard drug doxorubicin. Among the Mannich bases, 5b was the most active with an IC50 value of 0.034 g/l. The Schiff bases were found to be more active, when compared to Mannich bases derived from them. The morpholine derived Mannich bases were more
    合成了一系列的5-取代的4-氨基-3-巯基-1,2,4-三唑,并用各种3-取代的吡唑醛进行处理,以获得一系列新的席夫碱(3a – l)。在乙醇介质中(4a – e,5a – e),在甲醛存在下,通过与二苯胺/吗啉反应,很少有选定的席夫碱转化为曼尼希碱。这些新合成的化合物通过元素分析,IR,NMR和质谱研究进行了表征。使用MTT分析法对HepG2细胞中几种选定的Schiff和Mannich碱基的细胞毒性活性进行了比较研究。很少有经过筛选的希夫碱3a,3d,3e,3g和3h表现出剂量依赖性的细胞毒性活性,与标准药物阿霉素相比,3a最有效,IC 50值为0.018 g / l。在曼尼希碱中,5b活性最高,IC 50值为0.034 g / l。与衍生自其的曼尼希碱相比,席夫碱的活性更高。吗啉衍生的曼尼希碱比从二苯胺获得的碱更有效。
