title: Fluoro-ketopyranosyl nucleosides: synthesis and biological evaluation of 3-fluoro-2-keto-beta-D-glucopyranosyl derivatives of N4-benzoyl cytosine.
abstract: 1,2:5,6-Di-O-isopropylidene-alpha-d-glucofuranose on mild oxidation, reduction, fluorination, and deisopropylidenation followed by acetylation gave peracetylated 3-deoxy-3-fluoro-d-glucopyranose. This was coupled with silylated N(4)-benzoyl cytosine. The nucleoside was deacetylated and after several subsequent protection and deprotection steps afforded the desired 3-fluoro-2-keto-beta-d-glucopyranosyl derivatives. These novel synthesized compounds were evaluated for antiviral and cytotoxic activities against rotavirus, vesicular stomatitis virus, and the human colon adenocarcinoma cell line Caco-2, and have a promising potential in combating the rotaviral infections and in the treatment of colon cancer. As compared to AZT, a nucleoside analogue of reverse transcriptase inhibitor, the novel synthesized 1-(3,4-dideoxy-3-fluoro-beta-d-glycero-hex-3-enopyranosyl-2-ulose)-N(4)-benzoyl cytosine showed to be more effective at lower concentrations in inhibition of rotavirus infection as well as in the same range of antitumor activity.
