Novel S-aryltriazole acyclonucleosides were designed as structural analogs based on the previously identified antiviral aryltriazole acyclonucleosides in our laboratories. These S-aryltriazole nucleosides were synthesized in excellent yields via SNAr-mediated S-arylation, followed by subsequent ammonolysis. X-ray structural analysis revealed special structural feature brought by the S-linkage, which may represent an unfavorable factor contributing to the lack of anti-HCV activity for this family of triazole nucleosides.

A new fluorescent nucleoside based on 1,2,4-triazole nucleoside has been synthesised and its X-ray structure determined. Its binding properties, investigated by fluorescence spectroscopy, show that it can selectively bind Hg2+ with fluorescence quenching.
