Abstract: Comparative study of DNA biosynthesis inhibition, catalyzed by avian myeloblastose virus (AMV) reverse transcriptase (RT), human immunodeficiency virus (HIV) recombinant and native RT, has been performed. 3'-Azido-2',3'-dideoxy-thymidine 5'-triphosphate (AzTTP); 3'-azido-2',3'-dideoxythymidine 5'-methylenepho-sphonate-diphosphate; 3'-azido-2' ,3'-dideoxythymidine 5'-phosphate-phospono-acetate; 3'-azido-2',3'-dideoxythymidine 5'-phosphate-dibromomethylenephosphonate; 2',3'-O-isopropylidenecytidine 5'-methylenephosphonate-diphosphate (rC-iP-MPDP) were used as inhibitors. AzTTP proved to by the most active inhibitor (its activity against HIV RT is higher than against AMV RT), although not selective as the phosphonates; only rC-iP-MPDP has low selectivity.
