User: I need a drug with a acute oral toxicity (LD50 in rats) of 840.0 mg/kg.
Assistant: Of course Can you provide me with more constraints?
User: The drug should have a 19 carbon atoms, 0 oxygen atoms, and a molecular weight of 278.399 g/mol. Could you please only provide me with the SMILES and return no other information?
