Abstract
During the last decade, major advances have been made in our understanding of the physiology and pharmacology of G-protein-coupled receptor (GPCR) signaling. Several lines of studies have shown that GPCRs are targets for anesthetics and that some anesthetics inhibit the functions of Gq-coupled receptors. Nearly 160 GPCRs have been identified based on their gene sequence and ability to interact with known endogenous ligands. However, an estimated 500-800 additional GPCRs have been classified as “orphan” receptors (oGPCRs) because their endogenous ligands have not yet been identified. Given that known GPCRs are targets for anesthetics, these oGPCRs represent a rich group of receptor targets for anesthetics. This article highlights the effects of anesthetics on Gq-coupled receptors, and discusses whether GPCRs other than Gq-coupled receptors are targets for anesthetics.
