NMR studies of drug interaction with membranes and membrane-associated proteins

This review focuses on the recent developments in the study of drug interactions with biological membranes and membrane-associated proteins using nuclear magnetic resonance (NMR) spectroscopy and other spectroscopic techniques. Emphasis is placed on a class of low-affinity neurological agents as exemplified by volatile general anesthetics and structurally related compounds. The technical aspects are reviewed of how to prepare membrane-mimetic systems and of NMR approaches that are either in current use or opening new prospects. A brief literature survey covers studies ranging from drug distribution in simplified lipid matrix to specific drug interaction with neuronal receptors reconstituted in complicated synthetic membrane systems.
