User: I need a chemical with a log10 rat LD50 (oral exposure) of 3.88 log10(mg/kg).
Assistant: Sure Can you provide me with more details?
User: The chemical should have 0 Ghose filter violations, 0 violations of the lead likeness filter, 4 Lipinski rule violations, 45 carbon atoms, and 21 oxygen atoms.
Assistant: The chemical with the SMILES O=C(Nc1ccc2c(O)c(N=Nc3ccc(N=Nc4ccc(S(=O)(=O)O)cc4)cc3S(=O)(=O)O)c(S(=O)(=O)O)cc2c1)Nc1ccc2c(O)c(N=Nc3ccc(N=Nc4ccc(S(=O)(=O)O)cc4)cc3S(=O)(=O)O)c(S(=O)(=O)O)cc2c1 shows the desired properties.
