Abstract

In an attempt to combine the HIV-inhibitory capacity of different 2',3'-dideoxynucleoside (ddN) analogs, we have designed and synthesized several dimers of [AZT]-[AZT] and [AZT]-[d4T]. In addition, we also synthesized the dimers of 1-(1H-benzimidazol-1-yl)-1-deoxy-beta-D-ribofuranose. The in vitro anti-HIV activity of these compounds on a pseudotype virus, pNL4-3.Luc.R-E-, in the 293T cells has been determined. Among these compounds, 2,2'-(propane-1,3-diyl)bis[1-(beta-D-ribofuranosyl)-1H-benzimidazole] showed the highest anti-HIV activity with similar effect as AZT.
