Beschreibung

Application

Posaconazole has been used:

• in antifungal susceptibility testing of Aspergillus terreus[1]
• as a lanosterol 14α-demethylase (CYP51)-specific inhibitor to study its effects on membrane permeability in Candida albicans cells[2]
• to study its effects on promastigotes[3]

Biochem/physiol Actions

Posaconazole is a highly potent broadspectrum antifungal agent against the yeast infection caused especially by Candida sp.[4][5] It blocks the growth of fungi by inhibiting the enzyme lanosterol 14α-demethylase (CYP51).[4] In contrast to other antifungal azoles, posaconazole has been reported not to induce the efflux pump mechanism. Posaconazole exhibits antichagasic effects against different strains of Trypanosoma cruzi causing Chagas disease.[6]
