With the goal of limiting HIV-1 proliferation by increasing the mutation rate of the viral genome, we synthesized a series of pyrimidine nucleoside analogues modified in position 5 of the aglycone moiety but unmodified oil the sugar part. The synthetic strategies allow us to prepare the targeted compounds directly from commercially available nucleosides. All compounds were tested for their ability to reduce HIV-1 Proliferation in cell culture. Two of them (5-hydroxymethyl-2'-dU (1c) and 5-hydroxymethyl-2'-dC (2c)) displayed a moderate antiviral activity in single passage experiments. The same two compounds Plus two additional ones (5-carbamoyl-2'-dU (1a) and 5-carbamoylmethyl-2'-dU(1b)) were potent inhibitors of HIV-1 RT activity in serial passage assays, in which they induced a progressive loss of HIV-1 replication. In addition, viruses collected after seven passages in the presence of 1c and 2c replicated very poorly after withdrawal of these compounds, consistent with the accumulation of deleterious mutations in the HIV-1 genome.
