Task: Please create a text description for a molecule based on its representation.
SMILES: C=C1C(=O)O[C@@H]2[C@@H]1[C@H](OC(=O)C(C)C)C(=O)[C@@H](C)C[C@H](O)C[C@](C)(O)[C@H]2OC(=O)C(C)C
Constraint: Answer the question with complete sentences.
Result: The molecule is a germacranolide isolated from the aerial parts of Carpesium divaricatum. It exhibits cytotoxicity against the human tumor cells, A-549 (nonsmall cell lung), SK-OV-3 (ovary), SK-MEL-2 (skin), XF-498 (central nervous system) and HCT-15 (colon). It has a role as a metabolite and an antineoplastic agent. It is a cyclic ketone, a diol, a secondary alcohol, a tertiary alcohol and a germacranolide.
