In-Bridge Stereochemistry: A Determinant of Stapled Peptide Conformation and Activity

Chembiochem. 2024 Jan 8:e202300747. doi: 10.1002/cbic.202300747. Online ahead of print.ABSTRACTPeptide side chain stapling has been proven to be an effective strategy for fine-tuning peptide properties. This innovative approach leads to the creation of stapled peptides characterized by stabilized α-helical conformations, enhanced protein-binding affinity, improved cell permeability, superior enzymatic stability, and numerous other advantages. Extensive research has explored the impact of various stapling bridges on the properties of these peptides, with limited investigation into the influence of bridge chirality, until very recently. In this concise review, we provide a brief overview of the current state of knowledge regarding the stereochemistry within the bridges of stapled peptides, offering insights into the potential applications of chiral bridges in the design and development of stapled peptides.PMID:38191871 | DOI:10.1002/cbic.202300747
