User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is a dicarboxylic acid dianion that results from the deprotonation of both of the carboxylic acid groups of itaconic acid. It has a role as a human metabolite, a fungal metabolite and a Saccharomyces cerevisiae metabolite. It derives from a succinate(2-). It is a conjugate base of an itaconic acid.
Assistant: This is a molecule that fits your description: C=C(CC(=O)[O-])C(=O)[O-]
