Systematic 'foldamerization' of peptide inhibiting p53-MDM2/X interactions by the incorporation of trans- or cis-2-aminocyclopentanecarboxylic acid residues.

Abstract excerpt

A 'foldamerization' strategy for the discovery of biologically active peptide is evaluated using as an example the peptides that inhibit the p53-MDM2/X interactions. Application of a peptide scan with two constrained β-residue of trans and cis stereochemistry indicated a substitution pattern that leads to active molecules with enhanced conformational stability and high resistance to proteolysis. This procedure...
