User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is an N-acyl-L-alpha-amino acid anion that is the conjugate base of carnosine, obtained by deprotonation of the carboxy group. It is a conjugate base of a carnosine and a carnosine zwitterion.
Assistant: This is a molecule that fits this description: NCCC(=O)N[C@@H](Cc1cnc[nH]1)C(=O)[O-]
