Task: Please create a description for a molecule.
Molecule SMILES: C=C1C(=O)O[C@@H]2CC(C)=C3[C@@H](OC(C)=O)C[C@@](C)(O)[C@@H]3C[C@H]12
Constraint: Answer the question with full sentences.
Result: The molecule is a sesquiterpene lactone that is 3a,4,4a,5,6,7,9,9a-octahydroazuleno[6,5-b]furan-2(3H)-one substituted by a hydroxy group at position 5, methyl groups at positions 5 and 8, an acetyloxy group at position 7 and a methylidene group at position 3. It has been isolated from the aerial parts of Inula hupehensis. It has a role as a metabolite, an anti-inflammatory agent and a plant metabolite. It is a gamma-lactone, an acetate ester, an organic heterotricyclic compound, a tertiary alcohol and a sesquiterpene lactone.
