文摘

Methodology previously described by us was applied to the formation of novel conformationally restrained bicyclic sugar modified nucleosides, with introduction of an oxazole and a thiocarbamate ring at the 2^′,3^′-positions of the ribonucleosides. Two novel alkyl derivatives of 2^′,3^′-dideoxy-2^′,3^′-oxazole-β-d-uridine and a novel uridine 2^′,3^′-thiocarbamate were successfully synthesised. Conformational evaluation of all the synthesised compounds was conducted using the theoretical potential energy calculation via the macromodel v.6.0 molecular modelling programme. The conformationally restrained nucleosides described were evaluated against a wide range of DNA and RNA viruses. None of the compounds showed specific antiviral effects at subtoxic concentrations.
