Peptide therapeutics refers to the development and use of small protein fragments called peptides for therapeutic purposes. These peptides can be designed to interact with specific targets in the body, such as receptors or enzymes, to modulate their activity and produce a therapeutic effect. Peptide therapeutics have the potential to treat a wide range of diseases, including cancer, diabetes, and autoimmune disorders, due to their high specificity and low toxicity. Research in this area focuses on designing and optimizing peptides for improved efficacy, stability, and delivery, as well as exploring new applications for this promising class of drugs.
