Abstract Cationic antimicrobial peptides are a kind of peptides with anti-extrogenous pathogen activities. They are derived from biological defence system. Most peptides share common features such as small size, strong heat steadiness, wide antibacterial spectrum and special antibacterial mechanism, which are different from other general antibiotic. According to the research report, this paper overviewed sorts, antimicrobial mechanism, design and synthesis of cationic antimicrobial peptides.
