User: I want to create a molecule SMILES.
Assistant: This sounds very interesting. Should it be a special one?
User: Yes, the molecule should have a half life in humans after IV administration value close to 4.200 hours.
Assistant: Ok, this SMILES has a half life in humans after IV administration value of approximately 4.200 hours: Nc1[nH]c(=O)ncc1F
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#}
