Task: Please create a description for a molecule.
SMILES: C=C1C(=O)O[C@@H]2CC(C)=C([C@H](C)CCCOC(C)=O)[C@@H](O)[C@H]12
Constraint: Answer the question with full sentences.
Result: The molecule is a sesquiterpene lactone that is (3aS,4R,7aR)-3a,4,7,7a-tetrahydro-1-benzofuran-2(3H)-one with a methylidene at position C-3, a hydroxy at C-4, a methyl at C-6, and a (2S)-5-(acetyloxy)pentan-2-yl group at position C-5. A natural product found in Inula britannica var chinensis and Inula japonica. It has a role as a metabolite and an EC 1.14.13.39 (nitric oxide synthase) inhibitor. It is a sesquiterpene lactone, an acetate ester and an organic heterobicyclic compound.
