Task: Please create a text description for a molecule.
Molecule SMILES: Cn1c(=O)[nH]c2[nH]c(=O)n(C)c2c1=O
Constraint: Answer the question with full sentences.
Result: The molecule is an oxopurine that is 7,9-dihydro-1H-purine-2,6,8(3H)-trione substituted by methyl groups at N-1 and N-7. It is a metabolite of caffeine and is often found in human urine samples. It has a role as a human xenobiotic metabolite and a mouse metabolite. It derives from a 7,9-dihydro-1H-purine-2,6,8(3H)-trione. It is a conjugate acid of a 1,7-dimethylurate anion.
