Abstract

Electron spin resonance studies were carried out for 2mM 14N labeled 2H enriched 3-methoxycarbonyl-2,2,5,5-tetramethyl- pyrrolidine-1-oxyl (MC-PROXYL) in pure water and 100, 200, 300, 400 mM concentrations of liposomal solution and 3-carboxy-2,2,5,5,-tetramethyl-1- pyrrolidinyloxy (carboxy-PROXYL) in pure water and 400 mM concentration of liposomal solution by using L-band ESR spectrometer. This study reveals that the permeability of MC-PROXYL in liposomal solution and impermeability of carboxy-PROXYL in 400 mM concentration of liposomal solution. This study illustrates that the ESR can be used to differentiate between the intra-and extra-membrane water by loading the liposome vesicles with a lipid permeable nitroxyl spin probe. The lipid membrane permeability of two different nitroxyl spin probes was demonstrated.
