Task: Please create a description for a molecule.
SMILES: CC1(C)[C@@H](O)CC[C@]2(C)[C@H]3C[C@@H](O)[C@]4(C)C5=C(CC[C@H]4[C@]3(C)CC[C@@H]12)COC5=O
Constraint: Answer the question with complete sentences.
Result: The molecule is a scalarane sesterterpenoid isolated from the marine sponge Hyrtios erectus and has been shown to exhibit antineoplastic activity. It has a role as a metabolite and an antineoplastic agent. It is a scalarane sesterterpenoid, a terpene lactone, an organic heteropentacyclic compound, a gamma-lactone and a secondary alcohol.
