User: I want to generate a SMILES.
Assistant: This sounds very interesting. Should it be a special one?
User: Yes, the molecule should have a half life time in humans after IV administration value close to 1.900 hours.
Assistant: Ok, this SMILES has a half life time in humans after IV administration value of approximately 1.900 hours: N=C(N)N1CCC[C@@H](CNC(=O)C[C@H](NS(=O)(=O)c2ccc3ccccc3c2)C(=O)N(CC(=O)O)C2CC2)C1
