Task: Please create a description for a molecule.
Molecule SMILES: CC1=CC(=O)[C@@H](O)[C@]2(C)[C@H]3[C@@H](O)[C@H](O)[C@H](CO)[C@@H]4[C@@H](O)C(=O)O[C@H](C[C@@H]12)[C@@]43C
Constraint: Answer the question with full sentences.
Result: The molecule is a quassinoid that is picras-3-ene substituted by hydroxy groups at positions 1, 11, 12, 15 and 21 and oxo groups at positions 2 and 16. Isolated from the ethanol extract of the stem of Brucea mollis, it exhibits cytotoxic activity. It has a role as a plant metabolite and an antineoplastic agent. It is a delta-lactone, an enone, a pentol, an organic heterotetracyclic compound, a quassinoid and a secondary alpha-hydroxy ketone. It derives from a hydride of a picrasane.
