Task: Please create a text description for a molecule based on its representation.
SMILES: CCCCCCCC/C=C/CCCCCCCC(=O)OC(CNC(=O)C=C(C)C)C1=CC(=O)c2nccc3c2c1nc1ccccc13
Constraint: Answer the question with complete sentences.
Result: The molecule is an alkaloid ester obtained by formal condensation of cystodytin D with elaidic acid. It is isolated from the Okinawan marine tunicate Cystodytes dellechiajei and exhibits cytotoxicity against human epidermoid carcinoma KB cells. It has a role as a metabolite and an antineoplastic agent. It is an enamide, an enone, an organic heterotetracyclic compound, an alkaloid ester and a secondary carboxamide. It derives from a 3-methylbut-2-enoic acid, an elaidic acid and a cystodytin D.
