The synthesis and biological studies of some long chain esters containing Schiff bases and their ferrocenyl analogues were carried out. The 4-amino ferrocene was prepared by the reported method. Long chain esters were synthesized by the condensation of different aliphatic acids with the corresponding aldehyde. The esters were then reacted with aniline as well as with 4-aminophenyl ferrocene to give
进行了一些含有席夫碱及其二茂铁基类似物的长链酯的合成和生物学研究。通过报道的方法制备4-氨基二茂铁。长链酯是通过将不同的脂肪酸与相应的醛缩合而合成的。然后使酯与苯胺以及4-氨基苯基二茂铁反应,得到相应的席夫碱。所有合成的化合物均通过元素,FTIR和质子NMR研究进行了分析,还研究了其一系列的生物活性。通过冠gall瘤抑制试验测定。抗氧化剂和DNA保护活性分别通过DPPH自由基清除测定法和OH自由基诱导的氧化性DNA损伤测定法确定。在所有测试化合物中,o羟基p - ñ -octadecanoyloxy-benzylidine- p -ferrocenyl苯胺(FA2.1:含有希夫碱二茂铁)显示最高的抗肿瘤,DPPH自由基清除和DNA保护活性。
