Task: Please give me a SMILES based on the description below.
Description: The molecule is octaanion of preuroporphyrinogen arising from global deprotonation of the eight carboxy groups; major species at pH 7.3. It has a role as a human metabolite and a Saccharomyces cerevisiae metabolite. It is a conjugate base of a preuroporphyrinogen.
Result: O=C([O-])CCc1c[nH]c(Cc2[nH]c(Cc3[nH]c(Cc4[nH]c(CO)c(CC(=O)[O-])c4CCC(=O)[O-])c(CC(=O)[O-])c3CCC(=O)[O-])c(CC(=O)[O-])c2CCC(=O)[O-])c1CC(=O)[O-]
