Task: Please create a text description for a molecule based on its representation.
SMILES: CCC(C)[C@H]1NC(=O)[C@@H](CC(N)=O)NC1=O
Constraint: Answer the question with full sentences.
Result: The molecule is a member of the class of 2,5-diketopiperazines that is 2,5-diketopiperazine substituted by an (aminocarbonyl)methyl group at position 3 and an isobutyl group at position 6. It is isolated from the fungus Cordyceps sinensis and exhibits significant cytotoxicity against L-929, A375 and HeLa cell lines. It has a role as a metabolite and an antineoplastic agent.
