User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is an octacarboxylic acid anion obtained by deprotonation of all eight carboxy groups of uroporphyrinogen III. It has a role as a human metabolite and a Saccharomyces cerevisiae metabolite. It is a cyclic tetrapyrrole anion and an octacarboxylic acid anion. It is a conjugate base of a uroporphyrinogen III.
Assistant: This is a molecule that fits your description: O=C([O-])CCc1c2[nH]c(c1CC(=O)[O-])Cc1[nH]c(c(CC(=O)[O-])c1CCC(=O)[O-])Cc1[nH]c(c(CC(=O)[O-])c1CCC(=O)[O-])Cc1[nH]c(c(CCC(=O)[O-])c1CC(=O)[O-])C2
