User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is an D-alpha-amino acid anion arising from deprotonation of the carboxy groups and protonation of the guanidino group of D-octopine. It is a conjugate base of a D-octopine and a D-octopine dizwitterion.
Assistant: This is a molecule that fits your description: C[C@@H](N[C@@H](CCC[NH+]=C(N)N)C(=O)[O-])C(=O)[O-]
