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 6.600 hours.
Assistant: Got it, this SMILES has a drug half life time in humans after IV administration value of approximately 6.600 hours: O=P1(NCCCl)OCCCN1CCCl
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#}
