Regulation of protein–protein interactions using stapled peptides

Abstract

The targeting of protein-protein interactions (PPIs) that include secondary structure motifs such as the α-helix and β-sheet is a challenge in chem. biol. A new class of compds. called stapled peptides have been developed that mimic α-helix secondary structures involved in PPIs. These conformationally constrained peptides also show favorable physicochem. properties and so are promising lead compds. for drug discovery. This review focuses on the design aspects of hydrocarbon constrained α-helical proteomimetics and provides examples in which they target biol. relevant PPIs. [on SciFinder(R)]
