Oligomers of (R)-3-hydroxybutanoate (OHB) have previously been shown to transport cations through lipid bilayers. The ion-transport activity has been attributed to the formation of hydrophobic aggregates or pores, which have been identified by fluorescence-microscopy measurements of membrane-incorporated fluorescence-labeled OHBs. To obtain more information about these aggregates, we describe here
先前已证明(R)-3-羟基丁酸酯(OHB)的低聚物可通过脂质双层传输阳离子。离子迁移活性归因于疏水性聚集体或孔的形成,其已经通过结合有膜的荧光标记的OHB的荧光显微镜测量进行了鉴定。为了获得有关这些聚集体的更多信息,我们在这里描述通过固态19 F-NMR光谱技术进行结构研究的特定F标记的HB低聚物II – IV的合成。
