User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is an oxopurine in which the purine ring is substituted by oxo groups at positions 2 and 6 and N-9 is protonated. It has a role as a Saccharomyces cerevisiae metabolite. It is a tautomer of a 7H-xanthine.
Assistant: This is a molecule that fits your description: O=c1[nH]c(=O)c2[nH]cnc2[nH]1
