User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is a tetrapeptide composed of L-cysteine, two L-phenylalanine units and glycine joined in sequence by peptide linkages. It has a role as a metabolite. It derives from a L-cysteine, a L-phenylalanine and a glycine.
Assistant: This is a molecule that fits this description: N[C@@H](CS)C(=O)N[C@@H](Cc1ccccc1)C(=O)N[C@@H](Cc1ccccc1)C(=O)NCC(=O)O
