Allosteric ligands bind to G protein-coupled receptors (GPCRs; also known as seven-transmembrane receptors) at sites that are distinct from the sites to which endogenous ligands bind. The existence of allosteric ligands has enriched the ways in which the functions of GPCRs can be manipulated for potential therapeutic benefit, yet the complexity of their actions provides both challenges and opportunities for drug screening and development. Converging avenues of research in areas such as biased signalling by allosteric ligands and the mechanisms by which allosteric ligands modulate the effects of diverse endogenous ligands have provided new insights into how interactions between allosteric ligands and GPCRs could be exploited for drug discovery. These new findings have the potential to alter how screening for allosteric drugs is performed and may increase the chances of success in the development of allosteric modulators as clinical lead compounds.
