User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a triterpenoid of the nor-ceanothane-type isolated from the roots of Breynia fruticosa and has been shown to exhibit cytotoxicity against human cancer cell lines. It has a role as an antineoplastic agent and a plant metabolite. It is an organic heteroheptacyclic compound, an epoxide, a terpene lactone, a monocarboxylic acid and a triterpenoid.
Assistant: This is a molecule that fits this description: C=C(C)[C@@H]1CC[C@]2(C(=O)O)CC[C@]34C(=O)O[C@]5(CC[C@@H]3[C@@H]12)[C@@]4(C)CC[C@]12O[C@]51[C@@H](C)CC2(C)C
