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