Task: Please create a text description for a molecule.
Molecule SMILES: CCC(=O)OC1=C(C)[C@@H]2C[C@H]3OC(=O)[C@H](OC(=O)CC)[C@H]4[C@@]5(C(=O)OC)OC[C@]34[C@H]([C@@H](O)[C@@H]5O)[C@@]2(C)CC1=O
Constraint: Answer the question with complete sentences.
Result: The molecule is a quassinoid that is the 3,15-di-O-propionyl derivative of bruceolide. It has been isolated from Brucea javanica and Brucea sumatrana. It has a role as a plant metabolite. It is a delta-lactone, a cyclic ether, an enol, an enone, a methyl ester, an organic heteropentacyclic compound, a propanoate ester, a quassinoid and a diol. It derives from a bruceolide.
