Task: Please create a SMILES based on the text description below.
Description: The molecule is an organic anion obtained by selective deprotonation of the hydroxy groups at positions 2 and 2' of nicotine blue; major species at pH 7.3 (according to Marvin v 6.2.0.). It is a conjugate base of a nicotine blue.
Result: O=C1C=C(c2cc([O-])c(=O)[nH]c2[O-])C(=O)NC1=O
