User: I want to come up with a SMILES.
Assistant: This sounds very interesting. Should it be a special molecule?
User: Yes, the molecule can be described by:
The molecule is a cyclic tetrapyrrole anion obtained by deprotonation of the four carboxy groups of coproporphyrin III; major species at pH 7.3. It is a conjugate base of a coproporphyrin III.
Assistant: Got it, here you go, this SMILES fits your description: CC1=C(CCC(=O)[O-])c2cc3nc(cc4[nH]c(cc5[nH]c(cc1n2)c(C)c5CCC(=O)[O-])c(CCC(=O)[O-])c4C)C(CCC(=O)[O-])=C3C
