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 a human ether-à-go-go related gene (hERG) blocker (<10uM).
Assistant: Ok, this SMILES is not a human ether-à-go-go related gene (hERG) blocker (<10uM): CCN1C(=O)CNc2ncc(-c3ccc(-c4nc[nH]n4)nc3C)nc21
