User: I want to create a SMILES.
Assistant: This sounds very exciting. Should it be a special one?
User: Yes, 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
User: I want to {#come up with|create|generate!} a {#molecule |!}{SMILES__description}.

User: Yes, the molecule should {herg_blocker#not &NULL}be a {herg_blocker__names__noun}.
Assistant: {#Understood|Got it|Ok!}, this {SMILES__description} is {herg_blocker#not &NULL}a {herg_blocker__names__noun}: {SMILES#}
