User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a 4-pyridone in which the pyridone is iodo-substituted at C-3 and -5 and has a carboxymethyl substituent on nitrogen; used as a radiocontrast agent urography. It has a role as a radioopaque medium. It is a member of 4-pyridones, a monocarboxylic acid and an organoiodine compound.
