Advancing multicomponent strategies to macrobicyclic peptides

Von Wiley-VCH zur Verfügung gestellt

Macrocyclization of peptides is typically used to fix specific bioactive conformations and improve their pharmacological prop-erties. Recently, macrobicyclic peptides have received special attention owing to their capacity to mimic protein structures or be key components of peptide-drug conjugates. Here, we describe the development of novel synthetic strategies for two distinctive types of peptide macrobicycles. A multicomponent macrocyclo-dimerization approach is introduced for the production of interconnected β-turns, allowing two macrocyclic rings to be formed and dimerized in one pot. Also, an on-resin double stapling strategy is described for the assembly of lactam-bridged macrobicycles with stable tertiary folds.
