Task: Please create a text description for a molecule.
Molecule SMILES: O=c1nc2n(C[C@H](O)[C@H](O)[C@H](O)CO)cc(CO)nc-2c(=O)[nH]1
Constraint: Answer the question with full sentences.
Result: The molecule is the pteridine that is lumazine substituted with a hydroxymethyl group at C-6 and a 1-D-ribityl group at N-8. It derives from a ribitol and a lumazine.
