The use of ESR and specially designed spin probes has led to major breakthroughs in understanding the complexity of biological membranes. Research has been focused mainly on molecular events within the lipid bilayer, and few probes have been designed for studying events in the extracellular space near the membrane surface. We have prepared a series of amphiphilic spin probes in which an ethylene glycol
ESR和专门设计的旋转探针的使用在理解生物膜的复杂性方面带来了重大突破。研究主要集中在脂质双层内的分子事件,很少设计用于研究膜表面附近细胞外空间事件的探针。我们准备了一系列两亲性自旋探针,其中在疏水性锚和二甲苯基之间引入了乙二醇型亲水性间隔基,将二甲苯基置于细胞外空间中的膜上方。此外,包含氮氧化物基团的不成对电子的2pπ轨道将垂直于膜表面定向,从而使其在细胞寿命不同情况下对膜表面附近的结构和动力学性质的ESR研究更有用。
