Nanoformulation of Peptides for Pharmaceutical Applications: In Vitro and In Vivo Perspectives

Abstract

Peptides are short sequences of proteins consisting of two or more amino acids that are linked by peptide bonds. Peptide-based designs and drug deliveries can offer several advantages, such as antioxidant, antimicrobial, antihypertensive activities, along with immunomodulatory and antithrombotic properties, with hormone or drug-like potential. Peptide-based therapeutic formulations are used as drug candidates for the treatment of various diseases. However, there are several concerns associated with the efficacy of peptides in pharmaceutical design and delivery, including rapid degradation, limited solubility, and poor permeability. The nanoformulation of peptides has been identified as a promising approach for improving the stability of peptides and providing metabolic stability and bioavailability. This article provides an overview of the advances in the development of peptides for drug design and formulation applications. It discusses various peptide nanoformulation approaches as well as recent developments in the in vitro and in vivo analyses of nanoformulated peptides for pharmaceutical applications.
