The synthesis of three novel cationic gemini surfactants (10, 12, and 14) based on tartaric acid appended with biocompatible palmitoyl tails and head groups is described, and their aggregation in water, monolayer behaviour, DNA binding, and gene transfection activities are reported. The monolayer studies showed that the molecular area of the surfactants is determined by the head group, as it increased
描述了基于酒石酸的三种新型阳离子双子表面活性剂(10、12 和 14)的合成,并附有生物相容性棕榈酰尾和头基,并报告了它们在水中的聚集、单层行为、DNA 结合和基因转染活性。单层研究表明,表面活性剂的分子面积由头基决定,因为它从 10 个乙二胺头基经过 12 个赖氨酸头基到 14 个赖氨酸/乙二胺头基的组合增加。电子显微镜显示具有较小头部基团(10 和 12)的表面活性剂形成板状结构,可能是堆叠的双层,符合形状结构概念,而最大的表面活性剂 14 没有观察到结构。 o-噬菌体的 CD 光谱滴定
