Dimers and tetramers of linear 3-alkylpyridinium salts have been synthesized by an efficient synthetic pathway, which is also applicable to the preparation of higher oligomers. Mono-, di- and tetrameric compounds have been tested for antibacterial and hemolytic activities and for the inhibition of acetylcholinesterase and protein phosphatase 2A. Their activities were compared to those of the natural
直链3-烷基吡啶鎓盐的二聚体和四聚体已经通过有效的合成途径合成,其也可用于制备高级低聚物。已测试了单聚,二聚和四聚化合物的抗菌和溶血活性以及对乙酰胆碱酯酶和蛋白磷酸酶2A的抑制作用。将它们的活性与从地中海海绵雷尼拉沙雷分离的天然聚-3-辛基吡啶鎓生物碱的活性进行了比较。观察到较高的抗菌和抗乙酰胆碱酯酶活性随较高的低聚度而增加。
