Pterisolic acid B exhibits potential in pharmaceutical research due to its structural features associated with anti-inflammatory and antimicrobial activities. It has been investigated for its role in modulating cellular pathways involved in oxidative stress, making it a candidate for study in neurodegenerative and metabolic disorders. Additionally, its presence in certain fern species suggests a natural defense function, which may inspire the development of plant-based protective agents. Research remains in early stages, primarily in vitro, focusing on bioactivity screening and mechanism elucidation.
