User: I want to generate a SMILES.
Assistant: This sounds very interesting. Should it be a special molecule?
User: Yes, the molecule should have a Caco-2 cell permeability value close to -4.819 cm/s.
Assistant: Understood, this SMILES has a Caco-2 cell permeability value of approximately -4.819 cm/s: COC(=O)C1=CO[C@@H](C)[C@H]2CN3CCc4c([nH]c5ccccc45)[C@@H]3C[C@@H]12
