Fungistatic Potential and Inhibition of Fungal Yeast-hyphae switch of Candida spp. by Hecogenin Acetate.

Hecogenin acetate exhibits fungistatic activity and completely inhibits yeast-hyphae switching in Candida spp., despite having a higher IC₅₀ than fluconazole.

• Why it matters: Invasive fungal infections pose significant health risks for immunocompromised patients, and current antifungal agents often face issues like toxicity and resistance, highlighting the need for new treatments.
• What they did: The study evaluated susceptibility of Candida strains to hecogenin acetate, tested its combination with fluconazole using broth microdilution, and analyzed morphological changes in Candida albicans, Candida tropicalis, and Candida krusei.
• The result: Hecogenin acetate's fungistatic effect and ability to inhibit yeast-hyphae transition suggest it may offer complementary benefits by targeting fungal virulence, despite lower growth inhibition compared to fluconazole.
