Task: Please create a text description for a molecule based on its representation.
Molecule SMILES: CO[C@@H]1CCO[C@H]2O[C@@H]3C=C4CC[C@@H]5[C@H](CC[C@]6(C)[C@@H](C7=CC(=O)OC7)[C@@H](OC(C)=O)C[C@]56O)[C@@]4(C)C[C@H]3O[C@]21O
Constraint: Answer the question with complete sentences.
Result: The molecule is a steroid lactone isolated from Elaeodendron tangenala and Elaeodendron glaucum and exhibits antiproliferative activity against A2780 human ovarian cancer cells. It has a role as a metabolite and an antineoplastic agent. It is an acetate ester, a butenolide, a cyclic ether, an organic heterohexacyclic compound and a steroid lactone.
