Title: Optically Pure, Structural, and Fluorescent Analogues of a Dimeric Y4 Receptor Agonist Derived by an Olefin Metathesis Approach.
Authors: Liu M, Mountford SJ, Richardson RR, Groenen M, Holliday ND, Thompson PE.
Abstract: The dimeric peptide 1 (BVD-74D, as a diastereomeric mixture) is a potent and selective neuropeptide Y Y4 receptor agonist. It represents a valuable candidate in developing traceable ligands for pharmacological studies of Y4 receptors and as a lead compound for antiobesity drugs. Its optically pure stereoisomers along with analogues and fluorescently labeled variants were prepared by exploiting alkene metathesis reactions. The (2R,7R)-diaminosuberoyl containing peptide, (R,R)-1, had markedly higher affinity and agonist efficacy than its (S,S)-counterpart. Furthermore, the sulfo-Cy5 labeled (R,R)-14 retained high agonist potency as a novel fluorescent ligand for imaging Y4 receptors.
