User: I want to create a SMILES.
Assistant: This sounds very exciting. Should it be a special one?
User: Yes, the molecule should have a half life in humans after IV administration value close to 1.800 hours.
Assistant: Ok, this SMILES has a half life in humans after IV administration value of approximately 1.800 hours: CCN1CCN(C(=O)N[C@@H](C(=O)N[C@@H]2C(=O)N3C(C(=O)O)=C(CSc4nnnn4C)CS[C@H]23)c2ccc(O)cc2)C(=O)C1=O
