Effusanin E is primarily used for its potent antifungal properties, especially in agricultural settings where it helps protect crops from fungal pathogens. It is effective against a range of filamentous fungi, making it valuable in plant disease management. Due to its natural origin and mode of action, it serves as a lead compound in the development of eco-friendly fungicides. Additionally, Effusanin E has shown promise in biomedical research for its ability to inhibit biofilm formation, which could lead to applications in combating drug-resistant microbial infections. Its role in disrupting microbial membranes also makes it a candidate for use in antiseptic formulations and preservation systems.
