As a class of natural and synthetic peptides with a wide spectrum of antimicrobial activity, AMPs possess characteristics that make them attractive for therapeutic use. They are favored for their safety, low residue, and low resistance properties, with their unique antimicrobial mechanisms offering a distinct advantage over conventional antibiotics. This review provides an extensive analysis of the structure and mechanism of AMPs, focusing on their potential to combat infections caused by a wide range of pathogens.

The Structural Diversity and Functional Versatility of Antimicrobial Peptides

The structural landscape of AMPs is remarkably diverse, yet many share common features, including being relatively short (often less than twelve amino acids) and exhibiting amphipathic properties. This amphipathicity, characterized by a balance of hydrophobic and hydrophilic regions, is crucial for their primary mode of action: disruption of microbial membranes. AMPs can interact with negatively charged components of bacterial membranes, leading to pore formation and subsequent cell lysis, or they can translocate into the cell to interfere with essential intracellular processes. Research has highlighted that AMPs have been demonstrated to kill Gram negative and Gram positive bacteria, as well as fungi, parasites, and viruses.作者：Y Huan·2020·被引用次数：1772—Antimicrobial peptides (AMPs) area class of small peptides that widely exist in natureand they are an important part of the innate immune system of different ... Beyond their antimicrobial capabilities, some AMPs also exhibit immunomodulatory functions, further enhancing their therapeutic value.

The intricate properties and underlying mechanisms of bacterial antimicrobial peptides (BAMPs) are a significant area of study作者：YJ Gordon·2005·被引用次数：1007—This review summarizes their progress to date as commercial antimicrobialdrugs for topical and systemic indications.. These peptides are produced by bacteria themselves as a defense mechanism or can be harnessed for therapeutic purposes. The structural diversity of AMPs is vast, with variations in amino acid sequence, charge, and secondary structure contributing to their specific activity profiles. Understanding these structural characteristics is vital for designing novel AMPs with enhanced efficacy and reduced toxicity.
