Posaconazole is a broadspectrum triazole active against various yeasts and molds, including Aspergillus, Candida, Fusarium, and
Zygomycetes. Posaconazole inhibits the growth of fungi by inhibiting the lanosterol 14ademethylase enzyme (IC50s range from 7-
200 nM), which results in a disruption the synthesis of ergosterol, a key sterol necessary for fungal cell membrane integrity and for
the function of certain membranebound proteins.Posaconazole is a broad-spectrum, second generation, triazole compound with
antifungal activity. Posaconazole strongly inhibits 14alpha demethylase, a cytochrome P450-dependent enzyme. Posaconazole is a
sterol C14a demethylase inhibitor with an IC50 of 0.25 nM. Inhibition of 14-alpha-demethylase prevents the conversion of lanosterol to
ergosterol, an important component of the fungal cell wall. Inhibition of ergosterol synthesis changes the fungal cell membrane
composition and integrity, alters membrane permeability and eventually leads to fungal cell lysis. Compared to other azole
antifungals, posaconazole is a significantly more potent inhibitor of sterol 14alpha demethylase. Posaconazole is the most advanced
candidate for the treatment of Chagas disease. Posaconazole has entered in a phase II clinical trial in the treatment of mycoses.
