Synthesis and study of conformationally defined enantiomers of local anesthetics and conformationally defined enantiomers of fluorescent dyes designed to label electrically excitable membranes

Abstract: Conformationally defined enantiomeric local anesthetics and fluorescent dyes were synthesized. Neither the local anesthetics nor the fluorescent probes showed stereospecificity in interacting with nerve membranes. The fluorescence signals generated by the dyes showed excellent correlation with the time course and shape of the nerve action potential.
