User: I want to come up with a SMILES.
Assistant: This sounds very interesting. Should it be a special one?
User: Yes, the molecule should have a drug half life time in humans after IV administration value close to 3.200 hours.
Assistant: Got it, this SMILES has a drug half life time in humans after IV administration value of approximately 3.200 hours: Cc1nc2n(c(=O)c1CCN1CCC(c3noc4cc(F)ccc34)CC1)CCCC2
