User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a sterigmatocystin whose skeleton comprises a xanthone ring system ortho-fused to a dihydrofuranofuran moiety. It has a role as a metabolite and a carcinogenic agent. It is a member of sterigmatocystins and a cyclic acetal.
