User: I'm searching for the SMILES of a molecule that can be described as:
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.
Assistant: This is a molecule that fits your description: CCC(C)[C@H]1NC(=O)[C@@H](CC(N)=O)NC1=O
