Task: Please generate a molecule SMILES based on the description.
Description: The molecule is an azaspiro compound that is 1,3,6,8-tetraazaspiro[4.4]non-6-ene which is substituted by oxo groups at positions 2, 4, and 9. Both enantiomers are highly mutagenic products resulting from the oxidation of guanine and 8-oxo-7,8-dihydroguanine in DNA by reactive oxygen species. It has a role as a mutagen. It derives from a hydantoin.
Result: NC1=NC2(NC(=O)NC2=O)C(=O)N1
