Special Issue Information

Dear Colleagues,

Recent advancements in the discovery of allosteric modulators for G protein-coupled receptors (GPCRs) and kinases have revolutionized drug discovery and development. While most currently marketed drugs bind to the orthosteric site for the endogenous ligand, allosteric modulators bind to topographically distinct sites. Orthosteric sites are in general highly conserved across protein superfamilies and identification of highly selective ligands is challenging. Targeting allosteric sites on GPCRs and kinases has emerged as a successful strategy for identification of highly selective ligands with therapeutic utility for the treatment of disease states which previously could not be addressed due to inability to identify subtype selective ligands. In recent years, the discovery of GPCR allosteric modulators as treatments for CNS disorders including schizophrenia, Fragile X and Alzheimer’s disease and allosteric inhibitors for kinases have advanced into clinical development. This special issue invites original research including review articles on the pharmacology, chemical biology and medicinal chemistry of allosteric modulators including assay development and screening technologies, mechanism of action, structural features of binding sites and clinical research and development.

Title: Cross-antagonism as Example of Allosteric Regulation in G-protein-coupled Receptor Heteromers—Cross-antagonism in GPCR Heteromers

Abstract: G-protein-coupled receptors are expressed on the cell surface as heteromers: from heterodimers to hetero-oligomers. In the simplest case an heterodimer is constituted by two different receptors and, importantly, it provides a novel function, which is not merely the addition of the signaling properties of the individual receptors. Although the ultimate consequences of heteromer formation are still under scrutiny and under debate, it has been already demonstrated how dimerization and/or occupancy of one receptor in the dimer affects the binding of agonists to the partner receptor and/or affects the function of the heteromer. According to the current nomenclature these phenomena are considered allosteric. In fact heterodimers are prone to allosteric regulation, and these two mechanisms come by default. In the report the allosteric consequences of heteromerization and of agonist binding to the orthosteric centers in an heteromer are reviewed. Furthermore cross-antagonism, which is a frequently found allosteric modulation in heteromers, is presented and examples are provided and discussed from a physiological and a pharmacological point of view.
