User: I want to generate a molecule SMILES.
Assistant: This sounds very interesting. Should it be a special one?
User: Yes, the molecule should not be penetrating the blood brain barrier to reach the brain.
Assistant: Got it, this SMILES is not penetrating the blood brain barrier to reach the brain: C[N+]1(C)CCC(OC(=O)C(O)(c2ccccc2)C2CCCC2)C1.[Br-]
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 {penetrate_BBB#not &NULL}be {penetrate_BBB__names__adjective}.
Assistant: Got it, this {SMILES__description} is {penetrate_BBB#not &NULL}{penetrate_BBB__names__adjective}: {SMILES#}
