Synthesis and biological evaluation of 1,2-disubstituted carbonucleosides of 2-amino-6-substituted purine and 8-azapurine

One, two-disubstituted carbocyclic nucleoside analogues bearing a 2-amino-6-substituted (chloro, hydroxy or amino) purine or 8-azapurine base were prepared by constructing the base about (±)-2-aminocyclopentane methanol, and their activities against a selection of viruses and tumor cells were determined in vitro.
