Pachyaximine A exhibits significant antifungal activity, particularly against plant pathogenic fungi, making it a promising candidate for agricultural fungicides. It has been studied for its ability to inhibit spore germination and mycelial growth in fungi such as Botrytis cinerea and Fusarium species. Due to its natural origin and targeted mode of action, it is being explored as a bio-based alternative to synthetic fungicides in sustainable crop protection strategies. Additionally, its structural features are of interest in the development of novel antifungal agents through synthetic modification or analog design.
