User: I want to create a SMILES.
Assistant: This sounds very interesting. Should it be a special molecule?
User: Yes, the molecule can be described as:
The molecule is the cyclic tetrapyrrole anion formed by loss of a proton from each of the four carboxy groups of coproporphyrinogen I. It is a conjugate base of a coproporphyrinogen I.
Assistant: Got it, this SMILES fits your description: Cc1c2[nH]c(c1CCC(=O)[O-])Cc1[nH]c(c(CCC(=O)[O-])c1C)Cc1[nH]c(c(CCC(=O)[O-])c1C)Cc1[nH]c(c(CCC(=O)[O-])c1C)C2
