摘要

The state-of-the-art of ,α,-helical polypeptides for biomedical applications, with a special emphasis on the manipulation of helix-to-coil dynamic transition, conformation-associated anti-biofouling surfaces, cellular uptake regulation, and reducing immunogenicity of polypeptide-protein conjugates are reviewed.

Abstract

Synthetic polypeptides, also known as poly(,α,-amino acid)s (P,α,AAs), are biomimetic and biodegradable polymers holding great potential for a variety of biomedical applications. Possessing the same peptide bonds as natural proteins, polypeptides can also adopt typical well-defined secondary structures including ,α,-helix, which have been shown to significantly impact the physicochemical properties and biological outcomes of materials. In this feature article, we review the state-of-the-art progresses of ,α,-helical polypeptides for biomedical applications, with a special emphasis on the manipulation of helix-to-coil dynamic transition, conformation-associated anti-biofouling coatings, cellular uptake regulation, and reducing immunogenicity of polypeptide-protein conjugates. Finally, perspectives on outstanding challenges remained in this field and some important future directions are discussed.
