It is isolated from a fungal strain Phoma sp.BAUA2861 and acts as an inhibitor of the enzyme topoisomerase I. It has a role as a metabolite, an EC 5.99.1.2 (DNA topoisomerase) inhibitor, an antiviral agent, an antineoplastic agent and an antimicrobial agent. It is an organochlorine compound, a naphthochromene, a member of phenols and a member of p-quinones."}]
