User: I want to come up with a SMILES.
Assistant: This sounds very exciting. Should it be a special molecule?
User: Yes, the molecule should not be toxic in the SR-Antioxidant response element assay.
Assistant: Ok, this SMILES is not toxic in the SR-Antioxidant response element assay: O=[N+]([O-])c1ccc(Oc2ccc([N+](=O)[O-])cc2)cc1
