User: I want to create a SMILES.
Assistant: This sounds very interesting. Should it be a special molecule?
User: Yes, the molecule should have a half life time in humans after IV administration value close to 20.000 hours.
Assistant: Understood, this SMILES has a half life time in humans after IV administration value of approximately 20.000 hours: C=C(C)O[C@@]12CO[C@@H]1C[C@@H]1C[C@@]13C(=O)[C@H](OC(C)=O)C1=C(C)[C@@H](OC(=O)[C@H](O)[C@@H](NC(=O)OC(C)(C)C)c4ccccc4)C[C@@](O)([C@H](OC(=O)c4ccccc4)[C@H]23)C1(C)C
User: I want to {#come up with|create|generate!} a {#molecule |!}{SMILES__description}.
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#}
