antimicrobial-peptides-mode-of-action Antimicrobial peptides (AMPs) represent a rapidly advancing area in the fight against infectious diseases, with a growing number of these naturally occurring or synthetically developed molecules currently undergoing various stages of clinical trials. These peptides, often referred to as host defense peptides, are crucial components of the innate immune system, offering protection against a broad spectrum of pathogens including bacteria, fungi, and viruses.作者：L Cresti·2024·被引用次数：85—Antimicrobial peptides(AMPs) are molecules with an amphipathic structure that enables them to interact with bacterial membranes. The increasing recognition of their potential therapeutic applications, particularly in the face of rising antimicrobial resistance, has spurred significant research and development, leading to their evaluation in clinical settings for a range of conditions.
The journey of antimicrobial peptides from discovery to potential clinical application is marked by extensive preclinical research and a burgeoning number of clinical trials. These peptides exhibit a unique mechanism of action, often targeting microbial membranes, which makes them less susceptible to the development of resistance compared to traditional antibioticsAntimicrobial peptides: Application informed by evolution. This inherent advantage, coupled with their broad-spectrum activity and immunomodulatory effects, positions AMPs as a promising class of new antimicrobials. Researchers are actively exploring their efficacy in treating various infections, from superficial skin and wound infections to more systemic and challenging bacterial infections, including those caused by multi-drug resistant strainsAntimicrobial peptide biological activity, delivery systems and ....
Several key attributes contribute to the optimistic outlook for AMPs in clinical trials. Their amphipathic structure allows them to effectively interact with and disrupt microbial cell membranes. Furthermore, their ability to modulate the host immune response can enhance the body's own defenses against pathogens. This dual action—direct antimicrobial effect and immune system support—makes them versatile therapeutic agents作者：F Asif·2024·被引用次数：41—11.Peptide-based antimicrobial agents in clinical trials.
