Receptor inactivation by means of chromophore-conjugated receptor ligands and lasers is discussed. The results of preliminary experiments aimed at inactivation of FMRFamide receptors in snail neurons using a He-Ne laser and FMRFamide analogs conjugated with Azure B are presented. Because the conjugates synthesized apparently bound to another class of binding sites on the neuronal membrane, the FMRFamide receptor inactivation was not achieved. However, laser inactivation was demonstrated for the conjugate binding sites.
