Task: Please create a text description for a molecule.
SMILES: C=C1C(=O)O[C@@H]2/C=C(\C)[C@@H](O)C[C@H]3O[C@]3(C)C[C@@H](OC(=O)/C(C)=C/C)[C@@H]12
Constraint: Answer the question with complete sentences.
Result: The molecule is a sesquiterpene lactone of the heliangolide group isolated from Eupatorium kiirunense and Calea rotundifolia and exhibits cytotoxicity against human oral epidermoid (KB), cervical epitheloid (Hela) and liver (hepa59T/VGH) carcinoma cells. It has a role as an antineoplastic agent and a metabolite. It is a sesquiterpene lactone, an epoxide and an enoate ester. It derives from a tiglic acid.
