User: I want to come up with a SMILES.
Assistant: This sounds very interesting. Should it be a special molecule?
User: Yes, the molecule should not be a human ether-à-go-go related gene (hERG) blocker.
Assistant: Understood, this SMILES is not a human ether-à-go-go related gene (hERG) blocker: CCCCC(=O)N(Cc1ccc(-c2ccccc2-c2nn[n-]n2)cc1)[C@H](C(=O)[O-])C(C)C
