Triblock peptide-linker-lipid molecular design improves potency of peptide ligands targeting family B G protein-coupled receptors

Abstract

© The Royal Society of Chemistry 2015. Two peptide-linker-lipid constructs were designed and prepared which target the parathyroid hormone 1 receptor, a family B G protein-coupled receptor. Both show increased agonist activity in a cell-based assay. The lipid moiety enables the formation of micelle-like nanostructures, which is shown to hinder proteolytic digestion and is expected to reduce renal clearance.
