It has a role as an antineoplastic agent and an EC 5.99.1.3 [DNA topoisomerase (ATP-hydrolysing)] inhibitor. It is a furonaphthodioxole, a gamma-lactone, a beta-D-glucoside, a monosaccharide derivative, a member of thiophenes, an aromatic ether, a member of phenols and a cyclic acetal. It is functionally related to a podophyllotoxin."}]
