User: I want to create a molecule SMILES.
Assistant: This sounds very exciting. 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 2.800 hours.
Assistant: Got it, this SMILES has a drug half life time in humans after IV administration value of approximately 2.800 hours: CCCC1O[C@@H]2C[C@H]3[C@@H]4CCC5=CC(=O)C=C[C@]5(C)[C@H]4[C@@H](O)C[C@]3(C)[C@]2(C(=O)CO)O1

Assistant: {#This sounds very exciting. |This sounds very interesting. !}Should it be a special {#molecule|one!}?
User: Yes, the molecule should have a {half_life_duration__names__noun} value close to {half_life_duration#} {half_life_duration__units}.
Assistant: {#Understood|Got it|Ok!}, this {SMILES__description} has a {half_life_duration__names__noun} value of approximately {half_life_duration#} {half_life_duration__units}: {SMILES#}
