As a compound composed of multiple amino acids connected by peptide bond, polypeptide has a broad application prospect in the field of biomedicine.

In the treatment of diseases, peptide drugs are gradually becoming an important means of treatment. Many peptides are highly specific and bioactive and can act precisely on disease targets. For example, in the field of anti-tumor, some peptides can inhibit the growth and spread of tumor cells and induce apoptosis of tumor cells. In terms of antibacterial, polypeptides can destroy the cell membrane of bacteria and also have a certain inhibitory effect on drug-resistant bacteria. In the field of antiviral, peptides can interfere with the replication process of the virus and prevent the virus from infecting human cells. In addition, peptides can also be used to treat neurological diseases, cardiovascular diseases and other diseases.

In the field of diagnosis, peptides play an important role as biomarker detection reagents. Testing for specific peptide biomarkers can help doctors accurately diagnose the type and stage of disease. For example, certain tumor-associated peptides can be used as diagnostic indicators for early cancer, improving the detection rate of the disease. At the same time, peptides can also be used to develop new diagnostic kits to improve the accuracy and efficiency of diagnosis.

In terms of drug delivery systems, peptides have unique advantages. Peptides can be combined with drugs to form stable complexes and improve the targeting and bioavailability of drugs. For example, by combining anti-tumor drugs with specific peptides, the drugs can be targeted more precisely to tumor tissue, reducing damage to normal tissue. In addition, peptides can also act as drug carriers to deliver drugs to specific cells or tissues to achieve targeted therapy.
