User: I want to come up with a molecule SMILES.
Assistant: This sounds very exciting. Should I consider any constraints for the creation?
User: Yes, please. The molecule should not be a human ether-à-go-go related gene (hERG) blocker (<10uM).
Assistant: Got it, this SMILES is not a human ether-à-go-go related gene (hERG) blocker (<10uM): CCNC(=O)Nc1ccc2ncc(Nc3ccc(C)cc3)nc2n1
