User: I want to generate the SMILES of a molecule.
Assistant: This sounds very interesting. Should I consider any constraints for the creation?
User: Yes, please. The molecule should not penetrating the blood brain barrier.
Assistant: Got it, this SMILES is not penetrating the blood brain barrier: CC(C)c1nc(CN(C)C(=O)N[C@H](C(=O)N[C@@H](Cc2ccccc2)C[C@H](O)[C@H](Cc2ccccc2)NC(=O)OCc2cncs2)C(C)C)cs1
User: I want to {#come up with|create|generate!} the {SMILES__description} of a molecule.
Assistant: {#This sounds very exciting. |This sounds very interesting. !}Should I consider any {#constraints|specific points!} for the {#generation|creation!}?
User: Yes, please. The molecule should {penetrate_BBB#not &NULL}{penetrate_BBB__names__adjective}.
Assistant: {#Ok|Got it!},{# here you go,|!} this {SMILES__description} is {penetrate_BBB#not &NULL}{penetrate_BBB__names__adjective}: {SMILES#}
