Rational Design and Synthesis of Right-Handed d-Sulfono-γ-AApeptide Helical Foldamers as Potent Inhibitors of Protein-Protein Interactions.


ABSTRACT: Novel unprecedented helical foldamers have been effectively designed and synthesized. The homogeneous right-handed d-sulfono-γ-AApeptides represent a new generation of unnatural helical peptidomimetics, which have similar folding conformation to α-peptides, making them an ideal molecular scaffold to design α-helical mimetics. As demonstrated with p53-MDM2 PPI as a model application, the right-handed d-sulfono-γ-AApeptides reveal much-enhanced binding affinity compared to the p53 peptide. The design of d-sulfono-γ-AApeptides may provide a new and alternative strategy to modulate protein-protein interactions.
