Antimicrobial peptides are characterized by their relatively short amino acid sequences, typically ranging from six to fifty residues. Despite their small size, they exhibit a wide array of inhibitory effects against bacteria, fungi, parasites, and viruses. Their amphipathic nature, featuring both hydrophilic and hydrophobic regions, is key to their interaction with microbial cell membranes.作者：P Erriah·2025·被引用次数：12—This review explores theintricate properties and underlying mechanisms of BAMPs, emphasizing their diverse applications in addressing AMR. This interaction often leads to membrane disruption, a primary mechanism through which AMPs exert their antimicrobial activity.

While membrane disruption is a well-established mechanism, the action of AMPs is far more complex and varied. They can also interfere with intracellular processes, including DNA and RNA synthesis, protein synthesis, and enzyme activity.Antimicrobial Peptides and Their Biomedical Applications Some AMPs can induce oxidative stress within microbial cells or inhibit biofilm formation, a critical factor in persistent infections and antibiotic resistanceAntimicrobial Peptides and Their Biomedical Applications. The diverse mechanisms employed by AMPs contribute to their broad-spectrum activity and their potential to overcome resistance developed against conventional antibiotics.
Recent research has focused on understanding the intricate properties and underlying mechanisms of AMPs, particularly in combating antimicrobial resistance (AMR). The low incidence of resistance development against AMPs, compared to traditional antibiotics, is a significant advantage. This is often attributed to their multi-target approach and their ability to engage with microbial membranes, which are less prone to rapid evolutionary changes than specific intracellular targets.(PDF) A comprehensive review of antimicrobial peptides
The natural world is a rich source of AMPs. They are found in various biological fluids and secretions, including skin secretions of amphibians, insect hemolymph, and mammalian neutrophils. Identifying and characterizing these peptides is an ongoing area of researchAntimicrobial peptides: structure, functions and .... Traditional methods of discovery have been complemented by genome-mining approaches and sophisticated computational tools, including machine learning, to predict and identify novel AMP sequences.
Databases dedicated to AMPs play a crucial role in cataloging known compounds, their sources, structures, and activities. This information is invaluable for researchers aiming to understand the landscape of existing AMPs and to design new ones. Studies exploring plant antimicrobial peptides, for instance, reveal a vast, yet largely untapped, reservoir of potential therapeutic agents作者：AA Bahar·2013·被引用次数：2029—Here we review the history and new development of antimicrobial peptides(AMPs), a growing class of natural and synthetic peptides with a wide spectrum of ....
The potential of AMPs as therapeutic agents is immensePlant Antimicrobial Peptides and Their Main Families and .... Their favorable properties, such as low residue and low resistance development, make them attractive alternatives to conventional antibiotics. They are being investigated for topical and systemic applications, offering new strategies to treat infectious diseases.
However, challenges remain in their development into commercial drugs. These include issues related to stability, delivery, cost-effectiveness, and potential toxicity at higher concentrations. Molecular modification strategies are being employed to enhance their efficacy, stability, and specificity, thereby improving their therapeutic index.
Despite these hurdles, the review of clinical trials using AMPs provides valuable lessons learned, guiding future research and development. The focus is not only on harnessing existing AMPs but also on designing novel synthetic peptides that mimic or improve upon the functions of their natural counterparts. As our understanding of AMPs deepens, their role in combating infectious diseases and addressing the global challenge of antibiotic resistance is poised to expand significantly.
