Description

technical field

[0001] The invention belongs to the technical field of biomedicine, and in particular relates to a small molecular polypeptide RK12 and its application in the preparation of anti-acinetobacter baumannii infection drugs. Background technique

[0002] Antimicrobial peptides are small molecule polypeptides with biological activity that are induced in organisms, with a molecular weight of about 1000-7000 and composed of 10-60 amino acid residues. Antimicrobial peptides are high-efficiency, spectral antimicrobial peptide molecules that are rapidly produced by the body after being invaded by microorganisms to participate in the body's immune response. Antimicrobial peptides are widely used as effective defense molecules in the body. Thousands of antimicrobial peptides have been identified from microorganisms, plants, insects, arthropods, amphibians, mammals and even humans. The antibacterial mechanism of antimicrobial peptides is complex, but most of the theories ...
