A specific inhibitor of topoisomerase II, it is used (particularly as the hydrochloride salt) in the treatment of cancer, especially lung cancer, where it is a prodrug for the active metabolite, ambrucinol. It has a role as a topoisomerase II inhibitor, an antineoplastic agent and a prodrug. It is a quinone, a member of tetracenes, a methyl ketone, an anthracycline antibiotic and a primary amino compound."}]
