via reaction with fatty acids of varying chain lengths. The structure of these Schiff base esters were elucidated using chromatographic and spectroscopic techniques like GC–MS, 1H NMR, 13C NMR, and ESI–MS. Schiff base esters with shorter chain heptanoic (2a) and decanoic acid (2c) showed good activity against all the tested bacterial and fungal strains. The synthesized esters were also studied for cytotoxicity
通过使4-羟基苯甲醛与3-氨基甲基吡啶在乙醇中反应6小时(85%收率),然后通过与不同脂肪酸的反应将其酯化来制备席夫碱4-[(吡啶-3-基甲基亚氨基)-甲基]酚}链长。这些席夫碱酯的结构已使用色谱和光谱技术,如GC-MS,1 H NMR,13 C NMR和ESI-MS进行了阐明。带有较短链庚酸(2a)和癸酸(2c)的席夫碱酯)对所有测试的细菌和真菌菌株均显示出良好的活性。还研究了合成的酯对不同人类肿瘤细胞系(如HeLa,HepG2,A549,MDA-MB-231和MCF 7和Neuro2a)的细胞毒性。然而,短链(2a,2b)和中链脂肪酸(2d,2i)的席夫碱酯类具有良好的抗癌活性,并且对MDA-MB-231和MCF 7有选择性,而长链脂肪酸(2g)席夫碱酯类与母体分子席夫碱(1)相比,对MDA-MB-231具有选择性的抗癌活性。
