SusceptibilityThe Siderophore Transporter Sit1 Determines Susceptibility to the Antifungal VL-2397VL-2397 (previously termed ASP2397) is an antifungal, aluminum-chelating cyclic hexapeptide with a structure analogous to that of ferrichrome-type siderophores, whereby replacement of aluminum by iron was shown to decrease the antifungal activity of this compound. Here, we found that inactivation of an importer for ferrichrome-type siderophores, termed Sit1, renders ...
Mechanisms of ResistanceInhibition of Vesicular Transport Influences Fungal Susceptibility to FluconazoleFungal infections pose a substantial threat to the human population. They can cause either mild and relatively harmless infections or invasive and often lethal diseases in patients with a weakened immune system.
Mechanisms of ResistanceVacuolar Sequestration of Azoles, a Novel Strategy of Azole Antifungal Resistance Conserved across Pathogenic and Nonpathogenic YeastTarget alteration and overproduction and drug efflux through overexpression of multidrug transporters localized in the plasma membrane represent the conventional mechanisms of azole antifungal resistance. Here, we identify a novel conserved mechanism of azole resistance not only in the budding yeast Saccharomyces cerevisiae but also in the pathogenic yeast...
Experimental TherapeuticsAzole Resistance Reduces Susceptibility to the Tetrazole Antifungal VT-1161Tetrazole antifungals designed to target fungal lanosterol 14α-demethylase (LDM) appear to be effective against a range of fungal pathogens. In addition, a crystal structure of the catalytic domain of Candida albicans LDM in complex with the tetrazole VT-1161 has been obtained.
