    Area of Science:

    • Microbiology
    • Pharmacology
    • Mycology

    Background:

    • Polyene antibiotics are crucial antifungal agents.
    • Their mechanism of action involves targeting fungal cell membranes.
    • Understanding factors influencing their efficacy is vital for clinical use.

    Purpose of the Study:

    • To review the mode of action of polyene antibiotics.
    • To examine the impact of genetic and environmental factors on polyene activity.
    • To assess the future potential of polyenes in treating systemic fungal infections.

    Main Methods:

    • Literature review of polyene antibiotic mechanisms.
    • Analysis of studies on genetic and environmental influences.
    • Evaluation of clinical data and research on systemic mycoses.

    Main Results:

    • Polyenes act by binding to ergosterol in fungal membranes, leading to pore formation and cell death.
    • Variations in fungal genetics and environmental conditions significantly alter polyene susceptibility.
    • Resistance mechanisms can emerge, affecting treatment outcomes.

    Conclusions:

    • Polyene antibiotics remain important antifungal drugs, but their use is limited by toxicity and resistance.
    • Tailoring treatment based on pathogen genetics and environmental context can optimize efficacy.
    • Further research is needed to develop novel polyene derivatives or combination therapies for improved systemic mycoses treatment.
