Abstract
G-protein-coupled receptors (GPCRs) are one of the most tractable classes of drug targets. These dynamic proteins can adopt multiple active states that are linked to distinct functional outcomes. Such states can be differentially stabilized by ligands interacting with the endogenous agonist-binding orthosteric site and/or by ligands acting via spatially distinct allosteric sites, leading to the phenomena of 'biased agonism' or 'biased modulation'. These paradigms are having a major impact on modern drug discovery, but it is becoming increasingly apparent that 'kinetic context', at the level of both ligand-receptor and receptor-signal pathway kinetics, can have a profound impact on the observation and quantification of these phenomena. The concept of kinetic context thus represents an important new consideration that should be routinely incorporated into contemporary chemical biology and drug discovery studies of GPCR bias and allostery.
