User: I'm searching for the SMILES of a molecule that can be described as:
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.
Assistant: This is a molecule that fits this description: Cc1cn(CCO)c2nc(=O)[nH]c(=O)c-2n1
