User: I need a chemical with a log10 LD50 in rats (oral exposure) of 4.00 log10(mg/kg).
Assistant: Happy to help Can you provide me with more constraints?
User: The chemical should have 1 Ghose filter violations, 0 lead likeness filter violations, 3 violations of the Lipinski rules, 40 carbon atoms, and 18 oxygen atoms.
Assistant: The chemical with the SMILES representation of CCN(CC)c1nc(Nc2ccc(C=Cc3ccc(Nc4nc(Nc5cc(S(=O)(=O)O)ccc5S(=O)(=O)O)nc(N(CC)CC)n4)cc3S(=O)(=O)O)c(S(=O)(=O)O)c2)nc(Nc2cc(S(=O)(=O)O)ccc2S(=O)(=O)O)n1 displays the desired properties.
