User: Can you create the SMILES of a molecule that is not penetrating the blood brain barrier to reach the brain?
Assistant: Yes, I'm happy to help, here you go: CC[C@@]1(O)C[C@H](OC2CC(N(C)C)C(OC3CC(O)C(OC4CCC(=O)C(C)O4)C(C)O3)C(C)O2)c2c(cc3c(c2O)C(=O)c2c(O)cccc2C3=O)[C@H]1C(=O)OC
User: Can you {#give me|create|generate!} the {SMILES__description} of a molecule that is {penetrate_BBB#not &NULL}{penetrate_BBB__names__adjective}?
Assistant: {#Yes|Of course|Sure|Yes, I'm happy to help!}, here you go: {SMILES#}
