User: I want to come up with a molecule SMILES.
Assistant: This sounds very exciting. Should I consider any constraints for the creation?
User: Yes, please. The molecule should have a half life in humans after IV administration value of approximately 16.000 hours.
Assistant: Ok, this SMILES has a half life in humans after IV administration value of approximately 16.000 hours: Nc1nc(Cl)nc2c1ncn2[C@H]1C[C@H](O)[C@@H](CO)O1
