EN Two series of novel fluorinated nucleosides dimers with an unnatural 1,2,3-triazole linkage were synthesized. The obtained molecules were prepared using "click" chemistry approach based on copper(I) catalyzed Huisgen azide-alkyne cycloaddition. It was performed between 3 '- and 5 '-azido-nucleosides as the azide components, and the 3 '-O- and 5 '-O-propargyl-nucleosides as the alkyne components. Based on analysis of the (3)J(HH), (3)J(H1 ' C2) and (3)J(H1 ' C6) we estimated conformational preferences of sugar part and orientation around glycosidic bond. All described nucleosides dimers analogs were characterized by spectroscopic methods and evaluated for their in vitro cytotoxicity in three human cancer cell lines: cervical (HeLa), oral (KB) and breast (MCF-7).
