Antimicrobial Peptides with Anti-Candida Activity

Area of Science:

• Mycology
• Pharmacology
• Biochemistry

Background:

• Mycoses cause millions of infections globally, with invasive candidiasis being a major cause of morbidity and mortality.
• Increasing resistance of Candida species (e.g., Candida albicans, Candida parapsilosis, Candida glabrata, Candida auris) to azoles, polyenes, and echinocandins necessitates novel antifungal strategies.
• Antimicrobial peptides (AMPs) are a diverse group of molecules with potential as novel antifungal agents.

Purpose of the Study:

• To review antimicrobial peptides with demonstrated activity against Candida species.
• To highlight the potential of AMPs as a new therapeutic option against emerging multi-drug-resistant fungal pathogens.

Main Methods:

• Literature search for studies reporting antimicrobial peptides active against Candida.
• Compilation and description of 20 distinct antimicrobial peptides from various natural sources.
• Analysis of the antifungal activity spectrum and potential mechanisms of action.

Main Results:

• Twenty antimicrobial peptides from diverse origins were identified with activity against Candida.
• These peptides represent a potential new class of antifungal drugs to combat resistant strains.
• Antimicrobial peptides show promise in addressing the growing challenge of antifungal drug resistance.

Conclusions:

• Antimicrobial peptides are a viable and promising alternative to conventional antifungal drugs.
• Further research into AMPs is crucial for developing new treatments against invasive candidiasis.
• Nature provides a rich source of novel antifungal compounds to combat resistant fungal infections.
