Molecular models
Fluconazole is an antifungal medication used to treat fungal infections like candidiasis and mycosis. Fluconazole alters the active site of the lanosterol 14 alpha-demethylase preventing the demethylation of lanosterol, an essential step in the biosynthesis of ergosterol. Ergosterol plays an important structural role in the regulation of membrane fluidity and permeability.
