Task: Please create a description for a molecule based on its representation.
SMILES: O=c1[nH]c2nccn2c2nc[nH]c12
Constraint: Answer the question with full sentences.
Result: The molecule is a nucleobase analogue obtained by addition of an etheno group across positions N2 and 3 of guanine. It is an imidazopurine and a nucleobase analogue. It derives from a guanine.
