Task: Please create a description for a molecule.
Molecule SMILES: Cc1cn(CCO)c2nc(=O)[nH]c(=O)c-2n1
Constraint: Answer the question with full sentences.
Result: The molecule is a pteridine that is lumazine substituted with a 2-hydroxyethyl group at position 8 and a methyl group at position 6; one of 20 modifications to the potent microbial riboflavin-based metabolite antigen 5-(2-oxopropylideneamino)-6-D-ribityl aminouracil (5-OP-RU), an activator of mucosal-associated invariant T (MAIT) cells when presented by the MR1 protein (reported in MED:32123373). It has a role as an epitope. It derives from a lumazine.
