Abstract
Novel 5,6-dichlorobenzimidazole nucleoside analogues structurally related to the well-known riboside DRB have been synthesized. The 1′,2′- trans nucleosides were prepared by condensation of peracylated sugars with 5,6-dichlorobenzimidazole, whereas the 1′,2′- cis β-D-arabinofuranosyl and β-D-lyxofuranosyl nucleosides were obtained by inversion of configuration on the sugar moiety. Chiral acyclic derivatives were stereospecifically prepared by ring-opening of furano- or pyrano-nucleosides by means of periodate oxidation, followed by borohydride reduction. The in vitro activities against a range of DNA and RNA viruses, as well as the cytotoxicities in human T-lymphocyte MT-4 cells, have been determined for these novel compounds and for DRB. No truly selective activity (i.e. clearly below the cytotoxic concentration) was observed against any of the viruses used. Some of the compounds, including DRB, were cytotoxic to MT-4 cells at CC50 values of less than 10 μg ml−1.

Abstract
Non-natural l-nucleoside analogues are increasingly used as therapeutic agents to treat cancer and viral infections. To be active, l-nucleosides need to be phosphorylated to their respective triphosphate metabolites. This stepwise phosphorylation relies on human enzymes capable of processing l-nucleoside enantiomers. We used crystallographic analysis to reveal the molecular basis for the low enantioselectivity and the broad specificity of human 3-phosphoglycerate kinase (hPGK), an enzyme responsible for the last step of phosphorylation of many nucleotide derivatives. Based on structures of hPGK in the absence of nucleotides, and bound to l and d forms of MgADP and MgCDP, we show that a non-specific hydrophobic clamp to the nucleotide base, as well as a water-filled cavity behind it, allows high flexibility in the interaction between PGK and the bases. This, combined with the dispensability of hydrogen bonds to the sugar moiety, and ionic interactions with the phosphate groups, results in the positioning of different nucleotides so to expose their diphosphate group in a position competent for catalysis. Since the third phosphorylation step is often rate limiting, our results are expected to alleviate in silico tailoring of l-type prodrugs to assure their efficient metabolic processing.

The synthesis of new acyclic nucleosides is described. These syntheses were accomplished by various methods: glycosylation, selective or total deprotection, oxidation/reduction, chlorination or azidation of hydroxyl groups. The compounds were characterized with NMR, mass and IR spectroscopy. Antiviral properties of these compounds were evaluated on HIV-1 infected cell lines.

Abstract
A chiral acyclic nucleoside, one in which the ribose carbohydrate has been replaced with a glycerol-based linker, is prepared by glycosylating guanine at the N7-nitrogen. The stereochemically pure derivative is converted to a DMT-protected phosphoramidite for incorporation into DNA sequences. Sequence containing the acyclic N7-dG nucleoside are capable of forming DNA triplexes in which it is likely that the N1-H and N2-amino groups of the N7-dG are involved in recognition of the guanine base in G-C base pairs.

Abstract
The synthesis of a series of pyrazine analogues of the anti-herpes compound, acyclovir is described. These syntheses were accomplished by various methods: in the presence of a Lewis acid or NaH for hydroxyethoxymethyl and hydroxybutyl groups or by sequential oxidation/reduction of 1-(beta-D-ribofuranosyl)-2-pyrazinones for 2',3'-acyclonucleosides. Antiviral (HSV-1, CMV, Cox B4, HIV-1) properties of these compounds were determined.

Abstract
The monomeric and symmetrical dimeric 5'-hydrogenphosphonate derivatives of AZT were prepared and evaluated for their inhibitory properties against HIV-1 in several cell lines. The synthesis of the compounds was achieved by reaction of AZT with in situ prepared phosphorus tris(imidazolide) or with phosphonic acid in the presence of pivaloyl chloride. The two title compounds showed in vitro anti-HIV activity similar to (but not better than) that of AZT in three cell lines which were not deficient in thymidine kinase. On the other hand they were inactive in CEM-TK- cells. Pharmacokinetic studies in several media corroborate the assumption that these compounds must not be considered as 'true antiviral agents', but that they act by releasing their nucleoside entity.

Abstract
On the basis of three different models (namely: ddU, AZT and PMEA), mononucleotide phosphotriester derivatives were designed to be able to liberate the corresponding monophosphate (or phosphonate) inside the cell through a reductase-mediated activation process. It was demonstrated that the use of bis[S-(2-hydroxyethylsulfidyl)-2-thioethyl] esters of ddUMP (11), AZTMP (12) and PMEA (17) resulted in intracellular delivery of the parent monophosphate (or phosphonate). This point was corroborated by observation of an anti-HIV effect of, 11 in various cell lines, for 12 in CEM TK- cells and by the enhanced activity observed for 17. Furthermore, the reported decomposition data in cell extracts fully confirm the validity of this approach and show unambiguously the potential for intracellular reductase-mediated activation of the starting drug.
