- Overview
  - Voriconazole is a synthetic, second-generation, broad-spectrum triazole antifungal. It is a derivative of fluconazole with increased antifungal activity and specificity. It inhibits ergosterol synthesis, which is the major sterol in fungal cell membranes. The compound is used in the treatment of a broad spectrum of yeasts (including Candida) and molds (including Aspergillus). Voriconazole was patented in 1990 by Pfizer.
    Voriconazole is sparingly soluble in ethanol and DMSO.

    Background
    
    The mechanism of action of the azole family is to inhibit cytochrome P450 (specifically CYP450-dependent 14-alpha-sterol demethylase) which depletes ergosterol in fungal cell membranes. This increases cell permeability and disrupts normal cellular function.

- Applications
  - Application Description
    
    Spectrum: Voriconazole is fungistatic against all Candida species, including fluconazole-resistant strains of C. albicans. It is fungicidal against molds including many Aspergillus species.
    
    Microbiology Applications: Voriconazole is used as a control and ERG11 inhibitor in YPD medium. It can also be used to test its interactions with valproic acid (VPA) during VPA-synergy assessment (Chaillot et al, 2017).
    
    Insect Biology Applications: Voriconazole can be used in an invertebrate in vitro model with Galleria mellonella (greater wax moth) larva. It is an alternative animal model for studying antifungal efficacy on mycosis, including cryptococcosis. Using 12 Cryptococcus neoformans and C. gattii strains to assess capsule thickness, biofilm formation, survival, and morbidity. The compound was found to reduce fungal burden and dissemination in the larval tissue (de Castro et al, 2019).
