Abstract
Disclosed are polypeptide compounds containing at least one residue comprising a cyclically-constrained γ-amino acid residue. The compounds have the formula
where A is a hydrogen, hydroxy, amino- or carboxy-protecting group, Y is a single bond or a prolyl-containing linking group, and X and Y are γ-amino acid residues, provided that one of X or Y is a conformationally-restrained γ-amino acid residue, and “a,” “c,” and “d” are positive integers. The compounds find use as non-enzymatically degradable probes to mimic protein behavior in solution.
