Usaramine is primarily used in research settings for its biological activity, particularly in studies related to antimalarial and antiparasitic properties. It has shown potential in inhibiting the growth of Plasmodium species, making it a compound of interest in the development of new antimalarial drugs. Its mechanism involves interference with parasite metabolism, although exact pathways are still under investigation. Due to structural similarities with other alkaloids, usaramine is also studied for possible immunomodulatory and cytotoxic effects, especially in cancer cell lines. However, it remains mainly a research tool and is not currently used in clinical medicine.
