(HIV-1) and 1.30 μM (HIV-2)]. The β-d and β-l nucleosides also potently inhibit different drug-resistant strains of the HIV-1 virus (L100I, K103N, Y181C, and V106A). The selectivity indices and cytotoxic profiles of the β-d and β-l nucleosides are much better than those of the standard drugs AZT and d4T. Novel 4′-C-ethynyl isomeric dioxolane nucleoside analogues (β-d, α-d, β-l, and α-l, respectively)
