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 drug half life time in humans after IV administration value close to 4.200 hours.
Assistant: Ok, this SMILES has a drug half life time in humans after IV administration value of approximately 4.200 hours: N=C(N)NCCCC[C@@H]1NC(=O)CCSSC[C@@H](C(N)=O)NC(=O)[C@@H]2CCCN2C(=O)[C@H](Cc2c[nH]c3ccccc23)NC(=O)[C@H](CC(=O)O)NC(=O)CNC1=O
