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 drug half life time in humans after IV administration value close to 0.580 hours.
Assistant: Understood, this SMILES has a drug half life time in humans after IV administration value of approximately 0.580 hours: Nc1ncn([C@H]2C[C@H](O)[C@@H](CO)O2)c(=O)n1
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#}
4-amino-1-[(2R,4S,5R)-4-hydroxy-5-(hydroxymethyl)oxolan-2-yl]-1,3,5-triazin-2-one
