User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is a polycyclic cage xanthone isolated from the stems of Cratoxylum cochinchinense and has been shown to exhibit cytotoxic activity against human colon cancer cell line. It has a role as a metabolite, an antineoplastic agent and a plant metabolite. It is an organic heteropentacyclic compound, a cyclic ketone, a polycyclic cage, a cyclic ether and a member of phenols.
Assistant: This is a molecule that fits this description: CC(C)=CC[C@]12OC(C)(C)[C@H]3C[C@H](C=C4C(=O)c5c(O)cc(O)cc5O[C@@]431)C2=O
