Posaconazole, also known as SCH 56592 or Noxafil, is a novel triazole antifungal compound that potently inhibits 14α-demethylation in a variety of fungi, including Candida (C. albicans C43, C. albicans C288, C. albicans C600 and C. albicans C248) and Aspergillus (A. fumigatus ND158 and A. flavus ND134), with half maximal inhibition concentration IC50 of 0.007 μg/ml, 0.06 μg/ml, 0.2 μg/ml, 0.3 μg/ml, 0.03 μg/ml and 0.03 μg/ml respectively [1].
Posaconzole, an itraconzole derivative with fluorine replacing chlorine in the phenyl ring and hydroxylation in the side chain, binds to the heme cofactor on the active site of 14α-demethylase, which converts lanosterol to 14α-dimethy lanosterol, resulting in the disruption of the integrity and function of the fungal cell membrane and inhibition of fungal growth [2].
