title: In search of new inhibitors of HIV-1 replication: synthesis and study of 1-(2'-Deoxy-beta-D-Ribofuranosyl)-1,2,4-triazole-3-carboxamide as a selective viral mutagenic agent.
abstract: With the emergence of HIV strains resistant or cross-resistant to nearly all antiretroviral regimen, novel therapy approaches have to be considered. As a part of our current work on viral mutagenic compounds, we prepared 1-(2' -deoxy-beta-D-ribofuranosyl)-1,2,4-triazole-3-carboxamide (2' -deoxy-ribavirin) and its 5' -triphosphate derivative. The nucleoside mutagenic activity was evaluated on HIV-1 NL4-3 in CEMx174 cell culture. After 2.5 months, no reduction on HIV-1 viability was observed. On the other hand, in vitro experiments with purified HIV-1 RT demonstrated that the triphosphate analog can be incorporated opposite to several natural nucleosides.
