Antimicrobial peptides: promising compounds against pathogenic microorganisms.

Area of Science:

• Microbiology
• Biochemistry
• Pharmacology

Background:

• Conventional antibiotic use has led to widespread microbial resistance, necessitating novel therapeutic strategies.
• Antimicrobial peptides (AMPs) are a class of molecules produced by innate immunity across diverse organisms.
• AMPs exhibit broad-spectrum activity against bacteria, fungi, viruses, and parasites, with low propensity for resistance development.

Purpose of the Study:

• To review the current understanding of antimicrobial peptides (AMPs) as potential therapeutic agents.
• To discuss the mechanisms of action and molecular basis of AMP antimicrobial activity.
• To highlight recent advances, pharmacological development, and future applications of AMPs.

Main Methods:

• Literature review focusing on antibacterial and antifungal peptides.
• Analysis of AMP properties, including size, structure, and cationic nature.
• Discussion of in vitro studies on AMPs and their chemical analogs.

Main Results:

• AMPs demonstrate potent activity against Gram-negative and Gram-positive bacteria, as well as fungi.
• Key properties of AMPs include small size, amphipathic structure, and cationic charge.
• Novel AMPs and their synthetic analogs show significant therapeutic promise.

Conclusions:

• AMPs represent a viable alternative to conventional antibiotics for combating infectious diseases.
• Further research into AMPs' molecular mechanisms and pharmacological development is crucial.
• AMPs hold significant potential for future therapeutic applications against resistant microbes.
