Abstract

GPCRs play a critical role in human physiology and are a prime target for drug discovery globally. Novel insights into the functions of GPCRs are providing unique approaches to modulate these proteins to generate unique drug candidates. Next generation ligands include those with novel pharmacologies such as allosteric regulators as well pepducins, that affect the interaction of GPCRs with G proteins, to either block selective receptor signaling pathways or mimic the actions of intracellular domains of receptors, thereby activating GPCRs to signal selectively to intracellular pathways. We will review these new concepts and then discuss how they may be exploited using modern discovery technologies to provide novel drug candidates for the future. View Full-Text
