Pterosin D exhibits potential in biological research due to its benzofuran-based structure, akin to other bioactive natural products. It has been investigated for its anti-inflammatory, neuroprotective, and antioxidant properties, making it a candidate of interest in studies related to neurodegenerative disorders and oxidative stress. Additionally, Pterosin D shows mild inhibitory activity against certain enzymes involved in cellular signaling pathways, suggesting a role in modulating metabolic processes. Its natural occurrence in ferns also makes it a subject in phytochemical studies exploring plant defense mechanisms and secondary metabolite functions. Currently, it lacks commercial or industrial applications but is studied as a potential lead compound for future drug design.
