Task: Please create a molecule SMILES based on the description.
Description: The molecule is an extended quinone obtained by formal autoxidation of 2,3,6-trihydroxypyridine. It has a role as a biological pigment. It derives from a 2,3,6-trihydroxypyridine. It is a conjugate acid of a nicotine blue(2-).
Result: O=C1C=C(c2cc(O)c(=O)[nH]c2O)C(=O)NC1=O
