Aureobasidin A is primarily used as an antifungal agent due to its ability to inhibit inositol phosphorylceramide synthase, a crucial enzyme in sphingolipid biosynthesis. This makes it effective against a wide range of fungal pathogens, particularly in agricultural settings to protect crops from fungal infections. In research, it serves as a selective tool to study sphingolipid metabolism and its role in cellular processes. Additionally, it has potential applications in the development of antifungal therapies for human infections, offering a targeted approach to combat resistant fungal strains. Its unique mechanism of action makes it a valuable compound in both practical and experimental contexts.
