Chemical Structure
2-Thiouridine
- CAS No.: 20235-78-3
- Formula:C9H12N2O5S
- Molecular Weight:260.27
IUPAC Name: 1-((2R,3R,4S,5R)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-2-thioxo-2,3-dihydropyrimidin-4(1H)-one
InChIKey: GJTBSTBJLVYKAU-XVFCMESISA-N
SMILES: S=C(N1)N([C@@H]2O[C@H](CO)[C@@H](O)[C@H]2O)C=CC1=O
Biological Activity: 2-Thiouridine is an orally active modified nucleobase. 2-Thiouridine stabilizes U:A base pairs and destabilizes U:G wobble base pairs. 2-Thiouridine significantly improves the efficiency and accuracy of nonenzymatic replication of mixed-sequence A/U-containing RNA templates. 2-Thiouridine exhibits antiviral activity against multiple positive-sense single-stranded RNA viruses (DENV2, ZIKV, YFV, JEV, WNV, CHIKV, human coronaviruses ( [HCoV]-229E, HCoV-OC43, SARS-CoV), and MERS-CoV)[1][2][3][4].
