Disclosed are isolated, unnatural polypeptides containing cyclically-constrained β-amino acid residues and cyclically-constrained γ-amino acid residues. The compounds are unnatural and because they contain rotationally constrained residues that are not amenable to enzymatic degradation, the compounds are useful to probe protein-protein and other large molecule interactions.
本发明涉及一种含有环状约束β-
氨基酸残基和环状约束γ-
氨基酸残基的孤立、非自然
多肽。这些化合物是非自然的,因为它们含有旋转约束的残基,不易于酶降解,这些化合物可用于探测蛋白质-蛋白质和其他大分子相互作用。
