User: I want to come up with a SMILES.
Assistant: This sounds very interesting. Should it be a special molecule?
User: Yes, the molecule should have a half life in humans after IV administration value close to 1.300 hours.
Assistant: Ok, this SMILES has a half life in humans after IV administration value of approximately 1.300 hours: Nc1nc(=O)c2c([nH]1)NCC(CNc1ccc(C(=O)N[C@@H](CCC(=O)O)C(=O)O)cc1)N2C=O
