Synthesis and antiviral properties of new derivatives of 2-(alkylsulfanyl)-6-[1-(2,6-difluorophenyl)cyclopropyl]-5-methylpyrimidin-4(3H)-one

Based on 2-(2,6-difluorophenyl)acetonitrile a synthesis was performed of new bioisosteric prochiral analogs of anti-HIV-1 active derivatives of 2-alkoxy-6-benzylpyrimidin-4(3 Н )-one that we had previously obtained. The study using infected and nonifected strains of cells MT-4 made it possible to find in all prepared compounds a high anti-HIV activity whereas the cytotoxicity of the substances depended strongly on the structure of the alkylsulfanyl fragment of the molecule.
