User: I'm searching for the SMILES of a molecule that can be described as:
The molecule is a thiouridine in which the oxygen replaced by sulfur is that at C-4. It has a role as an affinity label and an antimetabolite. It is a thiouridine and a nucleoside analogue.
Assistant: This is a molecule that fits your description: O=c1[nH]c(=S)ccn1[C@@H]1O[C@H](CO)[C@@H](O)[C@H]1O
