User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a pentacyclic triterpenoid of the class of arborinane-type terpenoids isolated from the roots of Rubia yunnanensis. It has a role as an antineoplastic agent and a plant metabolite. It is an enone, an acetate ester, a diol, a cyclic terpene ketone and a pentacyclic triterpenoid.
Assistant: This is a molecule that fits this description: CC(=O)O[C@@H]1C[C@@H](C(C)C)[C@]2(CO)CC[C@@]3(C)[C@H]4C(=CC[C@]3(C)[C@@H]12)[C@@]1(C)C=CC(=O)C(C)(C)[C@@H]1C[C@@H]4O
