In recent years, it has become a hot research topic at home and abroad. Human erythropoietin, human thrombopoietin, life growth hormone, nerve growth factor and IL mimic peptides have been screened out abroad. Their amino acid sequences are different from the amino acid sequences of the corresponding cytokines, but have the advantages of cytokine activity and low molecular weight.
These cytokines mimic peptides are in the pre-clinical or clinical research stage. When insects are stimulated by the external environment, a large number of cationic peptides with antibacterial activity are produced, and more than 100 kinds of antibacterial peptides are screened out. In vitro and in vivo experiments, it has been confirmed that many antimicrobial peptides not only have strong bactericidal ability, but also have killing effect on tumor cells.
Many plant traditional Chinese medicine used in cardiovascular disease has the effect of lowering blood pressure, lowering blood lipid, dissolving thrombus and so on. It can be used not only as medicine, but also as health food. However, due to the uncertainty of its functional components, its application is greatly limited. Many active components are small molecular peptides, such as active peptides isolated from soybeans by Chinese scientists.
Can be absorbed directly through the small intestine, can prevent thrombosis, hypertension and hyperlipidemia, but also delay aging, improve the anti-tumor ability of the body. Many peptides used in cardiovascular diseases are also isolated from ginseng, tea, ginkgo leaves and other plants. In addition to the considerable progress made in these areas, other medicinal peptides have also made some progress in many other areas.
