Identification of Inhibitors of Fungal Fatty Acid Biosynthesis.

ABSTRACT: Fungal fatty acid (FA) synthase and desaturase enzymes are essential for the growth and virulence of human fungal pathogens. These enzymes are structurally distinct from their mammalian counterparts, making them attractive targets for antifungal development. However, there has been little progress in identifying chemotypes that target fungal FA biosynthesis. To accomplish this, we applied a whole-cell-based method known as Target Abundance-based FItness Screening using Candida albicans. Strains with varying levels of FA synthase or desaturase expression were grown in competition to screen a custom small-molecule library. Hit compounds were defined as preferentially inhibiting the growth of the low target-expressing strains. Dose-response experiments confirmed that 16 hits (11 with a
