The design of inhibitors of intracellular protein-protein interactions (PPIs) remains a challenge in chemical biology and drug discovery. We propose a cyclized helix-loop-helix (cHLH) peptide as a scaffold for generating cell-permeable PPI inhibitors through bifunctional grafting: epitope grafting to provide binding activity, and arginine grafting to endow(More)
Conformationally constrained peptides have been developed as an inhibitor for protein-protein interactions (PPIs), and we have de novo designed cyclized helix-loop-helix (cHLH) peptide with a disulfide bond consisting of 40 amino acids to generate molecular-targeting peptides. However, synthesis of long peptides has sometimes resulted in low yield according(More)
