Task: Please create a description for a molecule.
Molecule SMILES: CCCCCCCCCCCCCCCC(=O)C1=C(O)C(C)N(C)C1=O
Constraint: Answer the question with full sentences.
Result: The molecule is a member of the class of pyrrolidin-2-ones that is 1,5-dimethylpyrrolidine-2,4-dione substituted by a 1-hydroxyhexadecylidene moiety at position 3. Isolated from the marine sponge Melophlus sarasinorum and other species of genus Melophlus, it exhibits cytotoxicity against murine leukemia cell line. It has a role as a metabolite and an antineoplastic agent. It is an enol and a member of pyrrolidin-2-ones.
