It is isolated from the stems of Tephrosia toxicaria and exhibits antineoplastic activity. It has a role as a metabolite and an antineoplastic agent. It is an organic heteropentacyclic compound, an aromatic ether, a cyclic ketone, a tertiary alcohol, a secondary alcohol, a member of rotenones and a tertiary alpha-hydroxy ketone. It is functionally related to a tephrosin."}]
