Task: Please create a description for a molecule based on its representation.
SMILES: CCCCCCCCCCCCC[C@@H]1C[C@@H](O)C[C@@]2(CC[C@]3(C=CC(=O)C[C@@H]3O)O2)O1
Constraint: Answer the question with complete sentences.
Result: The molecule is an oxaspiro compound that is 1,7-dioxadispiro[5.1.5.2]pentadec-9-en-11-one substituted by hydroxy groups at positions 4 and 13 and a tridecyl group at position 2 (the (2R,4R,6S,8R,13S stereoisomer). It is isolated from the leaves of Amomum aculeatum and exhibits toxicity against some cancer cell lines like human lung carcinoma, hormone-dependent lung carcinoma and human breast carcinoma. It has a role as a metabolite and an antineoplastic agent. It is an oxaspiro compound, an organic heterotricyclic compound, an enone and a spiroketal.
