The exploration of peptide-drug conjugates (PDCs) also represents a significant trend, combining the targeting capabilities of peptides with the potency of small molecules or cytotoxic agents to create highly specific and effective therapeutics.
Peptide-based drugs offer several advantages over conventional small molecule therapeutics. They often exhibit higher selectivity due to their specific interactions with biological targets, leading to potentially fewer off-target side effects. Their ability to mimic natural hormones and peptides also makes them well-suited for targeting a wide range of diseases.1984 Nobel Prize in Chemistry - The Rockefeller University
Despite these advantages, challenges persist in peptide drug development. Proteolytic instability remains a concern, although strategies like cyclization and the development of non-natural amino acids are mitigating this issue. Overcoming the increased proteolytic instability compared to small molecules and monoclonal antibodies is a continuous area of research.Peptide Drug Discovery and Development Furthermore, optimizing delivery methods to ensure adequate absorption and distribution within the body is critical for therapeutic success.
