User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is conjugate base of D-nopaline in which the three carboxy groups are anionic and the secondary amino and guanidino groups are cationic; major species at pH 7.3. It is a conjugate base of a D-nopaline.
Assistant: This is a molecule that fits this description: NC(N)=[NH+]CCC[C@H]([NH2+][C@H](CCC(=O)[O-])C(=O)[O-])C(=O)[O-]
