User: I want to come up with a molecule SMILES.
Assistant: This sounds very interesting. Should it be a special one?
User: Yes, the molecule should not be a human ether-à-go-go related gene (hERG) blocking compound (<10uM).
Assistant: Ok, this SMILES is not a human ether-à-go-go related gene (hERG) blocking compound (<10uM): O=[N+]([O-])c1cn2c(n1)O[C@@H](COc1ccc(-c3ccc(F)cc3)nc1)CC2
