Recent Progress on Cyclic Peptides’ Assembly and Biomedical Applications

Abstract

AbstractCyclic peptides are important building blocks for forming functional structures and have been applied in various fields. Considering the significant structural and functional roles of cyclic peptides in materials science and the attributed biophysical advantages, we provide an overview of cyclic peptide types that can self‐assemble to form nanotubes, recent progress in stimuli‐triggered cyclic peptide assembly, and methods to construct peptide and polymer conjugates based on cyclic peptides with alternative chirality. Specifically, we highlight the roles that stimuli‐triggered cyclic peptides and their conjugates play in biomedical applications. Recent progress in other cyclic peptides acting as gelators in drug delivery and biomedicine are also summarized. These cyclic peptides with self‐assembly properties are expected to act as adaptive systems for drug delivery and selective disease targeting.
