Mastoparans(MP),a class of α-helix cationic insect-derived antimicrobial peptides,have a broad spectrum of biological activities including inhibiting bacteria,fungi,viruses,and parasites.Amino acid substitution,peptide modification,peptide chain cyclization,and dosage form modification can enhance the biological activities and target and reduce the toxicity of mastoparans.In this review,we summarize the structure,biological function and modification methods of mastoparans,and prospect the development of antibacterial drugs based on mastoparans,so as to provide reference for the research of mastoparans as a new antibacterial drug.
