It is isolated from fungal strains Phoma and Penicillium and acts as an inhibitor of the enzyme topoisomerase I. It has a role as an antimicrobial agent, an antineoplastic agent, an antiviral agent, an EC 5.99.1.2 (DNA topoisomerase) inhibitor and a Penicillium metabolite. It is a naphthochromene, a member of phenols and a member of p-quinones."}]
