User: I'm searching for the SMILES of a molecule that can be described by:
The molecule is a member of the class of sennosides that is rel-(9R,9'R)-9,9',10,10'-tetrahydro-9,9'-bianthracene-2,2'-dicarboxylic acid which is substituted by hydroxy groups at positions 4 and 4', by beta-D-glucopyranosyloxy groups at positions 5 and 5', and by oxo groups at positions 10 and 10'. The exact stereochemisty at positions 9 and 9' is not known - it may be R,R (as shown) or S,S. It is a member of sennosides and an oxo dicarboxylic acid.
Assistant: This is a molecule that fits your description: O=C(O)c1cc(O)c2c(c1)[C@H]([C@H]1c3cc(C(=O)O)cc(O)c3C(=O)c3c(O[C@@H]4O[C@H](CO)[C@@H](O)[C@H](O)[C@H]4O)cccc31)c1cccc(O[C@@H]3O[C@H](CO)[C@@H](O)[C@H](O)[C@H]3O)c1C2=O
