Popis: Triazolo-β-aza-ε-amino acid and its aromatic analogue ((Al)TAA/(Ar)TAA) in the peptide backbone mark a novel class of conformationally constrained molecular scaffolds to induce β-turn conformations. This was demonstrated for (Al)TAA in a Leu-enkephalin analogue and in a designed pentapeptide wherein the FRET process was established. Restricted rotation induced chirality and turn conformation into the achiral aromatic amino acid scaffold, (Ar)TAA, which in a short tripeptide backbone acted as a β-turn mimic as a β-sheet folding nucleator.
