Isolated from methylene chloride solubles of the Formosan soft coral Nephthea elongata, it exhibits cytotoxicity against selected cancer cells. It has a role as an antineoplastic agent and a coral metabolite. It is a cyclic ether, a diol, an organic heterotricyclic compound and a sesquiterpenoid."}]
