Antimicrobial Peptides and Cell-Penetrating Peptides: Non-Antibiotic Membrane-Targeting Strategies Against Bacterial Infections
Xucheng Huang, Guoli Li
Abstract
The prevalence of antimicrobial resistance (AMR) has been rising quickly in recent years. AMR has emerged as a significant obstacle to the treatment of infectious diseases, and many attempts have been made over the past decades to find the best antimicrobials to overcome it. Therefore, it is crucial to find new medicines to combat the global rise of AMR. Antimicrobial peptides (AMPs) and cell-penetrating peptides (CPPs), which target membranes, are promising antibiotic substitutes. AMPs and CPPs are short amino acid sequences with antibacterial activity as well as possible therapeutic benefits. In this review, we provide a thorough and systematic introduction to the advancement of research on AMPs and CPPs, including information on their classification, mechanism of action, current state of application, limitations and optimization.
