Marine Antimicrobial Peptides: Emerging Strategies Against Multidrug-Resistant and Biofilm-Forming Bacteria

Area of Science:

• Marine biotechnology and drug discovery
• Microbiology and infectious diseases
• Peptide therapeutics

Background:

• Antimicrobial resistance (AMR) is a critical global health threat, projected to exceed cancer mortality by 2050.
• Traditional antibiotic development faces stagnation, necessitating urgent exploration of novel therapeutic strategies.
• Marine organisms are a rich source of diverse bioactive compounds with antimicrobial potential.

Purpose of the Study:

• To review the potential of marine-derived antimicrobial peptides (AMPs) as a novel therapeutic class.
• To highlight the efficacy of marine AMPs against multidrug-resistant pathogens and challenging infections.
• To discuss current challenges and future directions in marine AMP research and development.

Main Methods:

• Comprehensive literature review of existing research on marine antimicrobial peptides.
• Analysis of AMP mechanisms of action, including membrane disruption and immune modulation.
• Evaluation of AMP efficacy against resistant bacteria, biofilms, and persister cells.

Main Results:

• Marine AMPs exhibit broad-spectrum antimicrobial activity and unique mechanisms distinct from conventional antibiotics.
• These peptides demonstrate significant potential in combating multidrug-resistant bacteria and biofilm-associated infections.
• Marine AMPs show promise in targeting persister cells and disrupting bacterial quorum sensing pathways.

Conclusions:

• Marine AMPs represent a promising frontier for developing next-generation therapeutics against antimicrobial resistance.
• Overcoming challenges in production scalability and clinical validation is crucial for therapeutic realization.
• Advancements in technology and bioinformatics are accelerating the discovery and optimization of marine AMPs.
