User: I want to create a molecule SMILES.
Assistant: This sounds very exciting. Should it be a special molecule?
User: Yes, the molecule should be penetrating the blood brain barrier to reach the brain.
Assistant: Got it, this SMILES is penetrating the blood brain barrier to reach the brain: CO/N=C(\C(=O)N[C@@H]1C(=O)N2C(C(=O)O)=C(CSc3nc(=O)c(=O)[nH]n3C)CS[C@H]12)c1csc(N)n1

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#}
