Arteannuin A is primarily used in pharmaceutical research due to its structural similarity to artemisinin, a well-known antimalarial compound. It serves as a key intermediate in the synthesis of more potent derivatives for testing against Plasmodium species, including drug-resistant strains. Its peroxide bridge is critical for generating reactive oxygen species that disrupt parasite metabolism. Beyond antimalarial applications, Arteannuin A is being investigated for anti-inflammatory, anticancer, and antiviral properties, particularly in targeting tumor cell proliferation and modulating immune responses. It is also used in analytical studies to develop detection methods for artemisinin-like compounds in biological samples.
