Understanding the Landscape of Protein and Peptide Drug Delivery

Proteins and peptides are fundamental components of biological systems, regulating a vast array of physiological processes.作者：J Yan·2019·被引用次数：143—Thisreviewfocuses on the origin, structural characteristics, action and potential mechanisms of anti-diabeticpeptideson the key enzymes andproteinsin ... As therapeutic agents, they offer targeted action and a reduced risk of adverse effects.This document discussesprotein and peptide drug delivery systems. It begins with an introduction to proteins and peptides and their use as drugs. However, their large molecular size, susceptibility to enzymatic degradation, and low permeability across biological membranes necessitate sophisticated drug delivery systems (DDS). Conventional administration routes, such as oral or intravenous, often prove insufficient for these biomolecules.

The parenteral route is most efficient for systemic delivery of proteins and peptides, with intramuscular (IM), intravenous (IV), and subcutaneous routes being commonly employed. Despite their efficacy, these methods can be inconvenient and painful for patients, driving the need for alternative, non-invasive approaches. The development of novel drug delivery systems aims to overcome these limitations, enhance therapeutic outcomes, and improve patient compliance.

Key Strategies in Protein and Peptide Drug Delivery

A variety of approaches are being explored to facilitate the effective delivery of protein and peptide drugs. These include:
