User: Can you create the SMILES of a molecule that is not a human ether-à-go-go related gene (hERG) blocker?
Assistant: Sure, here you go: O=C1NC(=O)C(c2ccccc2)(c2ccccc2)N1
User: Can you {#give me|create|generate!} the {SMILES__description} of a molecule that is {herg_blocker#not &NULL}a {herg_blocker__names__noun}?
Assistant: {#Yes|Of course|Sure|Yes, I'm happy to help!}, here you go: {SMILES#}
