Pandamarilactonine A exhibits significant antifungal activity, particularly against plant-pathogenic fungi, making it a potential candidate for agricultural fungicides. It has shown inhibitory effects on spore germination and mycelial growth in fungal strains such as Botrytis cinerea and Fusarium oxysporum. Due to its natural origin and specific mode of action, it is being studied for use in eco-friendly crop protection strategies. Additionally, its structural complexity has attracted interest in pharmaceutical research for developing novel bioactive compounds, though its primary application remains in the field of agrochemistry.
