Task: Please create a text description for a molecule.
SMILES: COC(=O)[C@@]12OC[C@]34[C@H]([C@@H](O)[C@@H]1O)[C@@]1(C)C(=O)C(O)=C[C@@H](C)[C@@H]1C[C@H]3OC(=O)[C@H](OC(=O)/C=C(\C)C(C)C)[C@@H]24
Constraint: Answer the question with complete sentences.
Result: The molecule is a quassinoid isolated from Brucea antidysenterica and has been shown to exhibit in vitro cytotoxicity towards several human tumour cell lines. It has a role as a metabolite and an antineoplastic agent. It is a delta-lactone, a cyclic ether, an enoate ester, an organic heteropentacyclic compound, a pentacyclic triterpenoid, a quassinoid, a triol, an enol and a methyl ester.
