Application of polypeptide
With recent advancements in biotechnology, polypeptides have found increasing use as therapeutic agents. They can serve in diagnostic, curative, and preventative applications and can be synthesized artificially to meet clinical demands.
Due to their unique properties, polypeptides combine the characteristics of both small molecule drugs and protein-based therapies, making them a highly researched class of molecules. Insulin, for example, was the first polypeptide drug introduced, and since then, over 80 polypeptide-based drugs have been commercialized. These include peptide vaccines, anti-cancer peptides, antiviral peptides, cardiovascular peptides, cytokine mimetic peptides, antimicrobial peptides, and diagnostic peptides.
One of the major advantages of polypeptide drugs is their reduced likelihood of inducing drug resistance. However, they also pose significant challenges, such as higher toxicity and lower stability compared to other drug types. The immunogenicity and instability of polypeptide drugs are often attributed to chemical reactions like deamidation, oxidation, hydrolysis, and the formation of incorrect structures.
