User: I want to come up with a molecule 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 1.400 hours.
Assistant: Got it, this SMILES has a half life time in humans after IV administration value of approximately 1.400 hours: CN1CC[C@]23c4c5ccc(O)c4O[C@H]2[C@@H](O[C@@H]2O[C@H](C(=O)O)[C@@H](O)[C@H](O)[C@H]2O)C=C[C@H]3[C@H]1C5
