Recent advances in self-assembled cyclic peptide-based smart nanostructures

Peptide chemistry has emerged as one of the growing fields of research. Peptide chemistry has positively impacted various areas, including biochemistry, medicine, hormonal therapy, drug delivery, food and the cosmetic industry, materials science, and nanotechnology, via the development of ways to change and imitate the shape and function of peptide structures. The structural changes of peptides and the employment of innovative synthetic techniques have left an indelible mark on a number of scientific disciplines. Numerous nanostructures based on simple and complicated peptides have been constructed so far; however, cyclic peptides have attracted a great deal of interest from the scientific community due to their wide range of applications and distinctive properties. These properties include self-assembly, morphogenesis, and charge distribution, among others. In addition, nanostructured cyclic peptides offer increased and effective performance due to their high stability, prolonged plasma half-life, membrane permeability, and efficient transport, among other attributes. Recent work indicates the manufacture of nanostructured cyclic peptides by chemical means. In this review, a brief investigation of the morphology of cyclic peptides was conducted. In addition, the therapeutic potential of these nanostructured cyclic peptides and the prognosis for a variety of potential applications are also discussed.
