User: I'm looking for the SMILES of a molecule that not is active against the human ether-à-go-go related gene (hERG)?
Assistant: This is a molecule that is not a hERG blocker: O=C([O-])C1=C[N+](C2CC2)=C2C=C(N3CC[NH2+]CC3)C(F)=C[C@H]2C1=O
User: I'm {#searching|looking!} for the {SMILES__description} of a molecule that {herg_blocker#not &NULL}{herg_blocker__names__verb}?
Assistant: This is a molecule that is {herg_blocker#not &NULL}a {herg_blocker__names__noun}: {SMILES#}
