Task: Please create a description for a molecule.
Molecule SMILES: C=C1C(=O)O[C@@H]2[C@@H]3[C@@](C)(CC[C@@H]12)[C@H](O)CC[C@@]3(C)O
Constraint: Answer the question with complete sentences.
Result: The molecule is a sesquiterpene lactone that is the 1beta-hydroxy derivative of arbusculin A. Isolated from Saussurea lappa, it exhibits inhibitory activity against melanogenesis. It has a role as a metabolite and a melanin synthesis inhibitor. It is a sesquiterpene lactone, a diol and an organic heterotricyclic compound. It derives from an arbusculin A.
