title: Synthesis, cytotoxic effect and antiviral activity of 1-(beta-D-arabinofuranosyl)-5-bromo-N4-substituted cytosine and 1-(beta-D-arabinofuranosyl)-5-bromo-4-methoxypyrimidin-2(1H)-one derivatives.
abstract: A convenient and mild synthesis of 5-bromo-N4-substituted-1-(beta-D-arabinofuranosyl)cytosine and 5-bromo-O4-methyl-1-(beta-D-arabinofuranosyl)pyrimidin-2(1H)-one derivatives by selective oxyfunctionalization of the corresponding 4-thionucleosides with 3,3-dimethyldioxirane is reported. The cytotoxicity and the antiviral activity against parainfluenza 1 (Sendai virus) of all new synthesized products are also reported.
