Abstract
This review covers studies which exploit triazole-modified nucleic acids in the range of chemistry and biology to medicine. The 1,2,3-triazole unit, which is obtained via click chemistry approach, shows valuable and unique properties. For example, it does not occur in nature, constitutes an additional pharmacophore with attractive properties being resistant to hydrolysis and other reactions at physiological pH, exhibits biological activity (i.e., antibacterial, antitumor, and antiviral), and can be considered as a rigid mimetic of amide linkage. Herein, it is presented a whole area of useful artificial compounds, from the clickable monomers and dimers to modified oligonucleotides, in the field of nucleic acids sciences. Such modifications of internucleotide linkages are designed to increase the hybridization binding affinity toward native DNA or RNA, to enhance resistance to nucleases, and to improve ability to penetrate cell membranes. The insertion of an artificial backbone is used for understanding effects of chemically modified oligonucleotides, and their potential usefulness in therapeutic applications. We describe the state-of-the-art knowledge on their implications for synthetic genes and other large modified DNA and RNA constructs including non-coding RNAs.

Abstract
Two series of novel fluorinated nucleosides dimers with an unnatural 1,2,3-triazole linkage were synthesized. The obtained molecules were prepared using "click" chemistry approach based on copper(I) catalyzed Huisgen azide-alkyne cycloaddition. It was performed between 3'- and 5'-azido-nucleosides as the azide components, and the 3'-O- and 5'-O-propargyl-nucleosides as the alkyne components. Based on analysis of the 3 JHH, 3 JH1'C2 and 3 JH1'C6 we estimated conformational preferences of sugar part and orientation around glycosidic bond. All described nucleosides dimers analogs were characterized by spectroscopic methods and evaluated for their in vitro cytotoxicity in three human cancer cell lines: cervical (HeLa), oral (KB) and breast (MCF-7).

Abstract
The fluorinated nucleoside dimers with a 1,2,3-triazole linkage are novel compounds within the field of bioorganic chemistry. We report on the synthesis and properties of two groups of nucleoside dimers analogs possessing a different arrangement of the 1,4-disubstituted 1,2,3-triazole linkage. Based on analysis of the 3JHH, 3JH1'C2, and 3JH1'C6 we estimated conformational preferences of sugar part and orientation around glycosidic bond. These compounds show moderate anticancer activity, with cytostatic studies in three different cancer cell lines.

Abstract
The nucleosides modified in the 2’- and/or 3’-position have been known for
years and include important, bioactive compounds such as zidovudine, cytarabine, didanosine,
puromycin, and fludarabine. This group consists of analogs with altered configuration,
2’,3’-dideoxy and 2’,3’-dideoxy-didehydro nucleosides, as well as derivatives with
additional substituents. These compounds are often targeted against viruses and tumors.
The sugar-base anhydro nucleosides have been known since the middle of the 20th century.
However, their application has not yet been fully explored and described. The number
of 2’,3’-dimodified derivatives, obtainable through sugar-base anhydrocyclic synthons,
could be vast, especially taking into consideration various combinations of S-alkyl,
S-aryl, O-alkyl, O-aryl, halogen, triazole, amine and azide substituents in both pyrimidine
and purine nucleosides. Furthermore, application of anhydrocyclic structures can be an efficient method of introducing
isotope labeled groups. The aim of this article is to provide an overview of the known methods of
functionalization of the 2’- and/or 3’-position of nucleosides, using anhydrocyclic structures, and also to present
a future outlook for this subject.

Abstract
We have designed a new type of AZT and ddU phosphoramidate diesters containing various combinations of 2-, 3-, 4-aminopyridine and 2-, 3-, 4-hydroxypyridine moieties attached to the phosphorus center, as potential anti-HIV pronucleotides. Depending on the pKa values of the aminopyridines and the hydroxypyridines used, alternative synthetic strategies based on H-phosphonate chemistry were developed for their preparation. Synthetic aspects of these transformations and the biological activity of the synthesized compounds are discussed.

Abstract
We describe a simple method for the synthesis of modified dinucleosides containing pyrimidine nucleoside analogues (2'-deoxyuridine, thymidine and 5-fluoro-2'-deoxyuridine). Six different dimers with a 1,2,3-triazole linkage were obtained by azide-alkyne 1,3-dipolar cycloaddition (click reaction), starting from propargylated 2'-deoxyuridine and 5'-azido-nucleoside derivatives. Their cytotoxic activity was tested in five human cancer cell lines: cervical (HeLa), high grade gliomas (U-118 MG, U-87 MG, T98G), liver (HepG2), and normal human fibroblast cell line (MRC-5) using the sulforhodamine B (SRB) assay. The experiment showed that the obtained dimers with a 1,2,3-triazole moiety were very stable compounds, also in the physiological-like media, and had no anticancer activity.

Among the investigated compounds, ribonucleosides containing 6-chloropurine (3), 7-guanine (5) and a pyrrolopyrimidine (18) as nucleobases, show promising anti-glioma activity with good selectivity indices, and can be considered as lead structures for further anti-cancer studies.

Abstract
Mitsunobu reaction of partially acylated uridine proceeds with high regioselectivity for intramolecular SN2 anhydro linkage closuring. Under the reaction conditions, an isomeric mixture of diacyl uridine derivatives with either free 2'- or 3'-hydroxyl group was transformed into a single cyclonucleosidic product, 2,2'-anhydro-3',5'-di-O-acyluridine. This paper presents a possible mechanism of the reactions, the explanation of observed phenomenon based on semiempirical and density functional theory (DFT) calculations and possible utility of this synthetic pathway.

Abstract
This review presents synthesis and chemistry of nucleoside analogs, possessing an additional fused, heterocyclic ring of the "etheno" type, such as 1,N(6)-ethenoadenosine, 1,N(4)-ethenocytidine, 1,N(2)-ethenoguanosine, and other related derivatives. Formation of ethenonucleosides, in the presence of α-halocarbonyl reagents and their mechanism, stability, and degradation, reactions of substitution and transglycosylation, as well as their application in the nucleoside synthesis, have been described. Some of the discussed compounds may be applied as chemotherapeutic agents in antiviral and anticancer treatment, acting as pro-nucleosides of already known, biologically active nucleoside analogs.

Abstract
New aromatic and aliphatic 3'-O-acyl-5-fluoro-2'-deoxyuridine derivatives were synthesized and evaluated as candidates for prodrugs against various cancer cell lines. As the most promising candidate for antimalignant therapeutics was found a dual-acting acyl derivative 7h, which apparently released not only the known anticancer nucleoside, 5-fluoro-2'-deoxyuridine (FdU), but also an additional active metabolite, acetylsalicylic acid, reinforcing thus therapeutic effect of FdU. Promising therapeutic indices showed also some aromatic dicarboxylic acids derivatives decorated with FdU esters (11 and 12).

Abstract
A series of new 3'-O- and 5'-O-propargyl derivatives of 5-fluoro-2'-deoxyuridine (1-4) was synthesized by means of propargyl reaction of properly blocked nucleosides (2,4), followed by the deprotection reaction with ammonium fluoride. The synthesized propargylated 5-fluoro-2'-deoxyuridine analogues (1-4) were evaluated for their cytotoxic activity in three human cancer cell lines: cervical (HeLa), oral (KB) and breast (MCF-7), using the sulforhodamine B (SRB) assay. The highest activity and the best SI coefficient in all of the investigated cancer cells were displayed by 3'-O-propargyl-5-fluoro-2'-deoxyuridine (1), and its activity was higher than that of the parent nucleoside. The other new compounds exhibited moderate activity in all of the used cell lines.

Abstract
Recently, AZT (N-pyridyl)phosphoramidates were reported as a new type of potential anti-HIV therapeutics. In continuation of that work, here we present new (N-heteroaryl)phosphoramidate derivatives of antiviral 2',3'-dideoxynucleosides containing other types of N-heteroaryl moieties, particularly those with higher lipophilicity. The present studies comprise mechanistic investigations using (31)P NMR correlation analysis, which permitted improvements in the synthetic procedures. The obtained compounds were tested in biological systems to establish their cytotoxicity and anti-HIV activity. The results were analyzed with respect to possible correlations between biological and physico-chemical properties of the phosphoramidates studied, to get some insight into their antiviral mode of action.

Abstract
Abstract
Cytokinins are essential plant hormones that regulate numerous physiological processes. Recently, a protein was identified in mung bean (Vigna radiata) and characterized as a cytokinin-specific binding protein (VrCSBP). Fluorescence correlation spectroscopy was used to investigate the interaction between VrCSBP and its ligands. The synthetic cytokinin, N-phenyl-N′-(4-pyridyl) urea, was labeled with two fluorophores, 7-nitro-2,1,3-benzoxadiazole and rhodamine B. Protein-ligand binding was analyzed in an equilibrium saturation binding experiment and confirmed by the competition assay. Surprisingly, it was found that VrCSBP binds not only to cytokinins, but also to gibberellins. In addition, in the presence of natural cytokinins and gibberellins, two populations of VrCSBP that differ in their diffusion coefficients were detected. The diffusion coefficients of these two populations could be related to mono- and dimeric states, which suggests a new mode of operation in ligand binding by VrCSBP, in which dimerization induced by natural ligands enhances the ligand binding capacity of the protein.

Abstract
Di-aryl nucleoside phosphotriesters have been explored as a new type of pronucleotides for the purpose of anti-HIV-1 therapy and efficient synthetic protocols, based on H-phosphonate chemistry, have been developed for the preparation of this class of compounds. It was found that anti-HIV-1 activity of the phosphotriesters bearing an antiviral nucleoside moiety (AZT, ddA) and also ddU was due, at least partially, to intracellular conversion into the corresponding nucleoside 5'-monophosphates, and their efficiency correlated well with the pK(a) values of the aryloxy groups present.

Abstract
Secondary metabolites, which have vital environmental and allelopathic functions for a host, and long tradition of ethnopharmacological applications preceding modern medicinal use, often occur in their native state as glycosides. The role of sugar moiety looks completely different from plant physiology point of view and from drug discovery and development perspective. Based on a short survey of cases, in which structural modification of natural glycone (saccharide part of a low molecular weight secondary metabolite) resulted in advantageous pharmacological changes, we postulate that glycosides of natural origin can be quite promising as drug leads, based on general rules of drug design. In particular, polyfunctional sugar moieties offer ample opportunities for almost continuous changes in shape, electron density and polarity. By the same token, glycosylation of other biologically active natural products, which are not natively glycosylated, can be viewed as a tool for tune up of their activity in direction of higher efficacy and better selectivity. Despite of considerable advances towards turning enzymatic glycosylations into biotechnological processes, chemical transformations still remain more practical, particularly for synthesis of modified glycosides, both: in research laboratory and in industry.

Abstract
Aryl nucleoside 5'-H-phosphonates 4 bearing AZT or 2',3'-dideoxyuridine moieties were subjected to reaction with various aromatic aldehydes to produce nucleoside 5'-alpha-hydroxyphosphonate derivatives 2 as potential anti-HIV agents. Stability of the title compounds in cell culture media was investigated and three distinct decomposition pathways were identified. The anti-HIV activity of hydroxyphosphonates 2 correlates well with the type and extent of their chemical or enzymatic degradation in culture medium (RPMI 1640 containing 10% FBS), suggesting that aryl nucleoside 5'-hydroxyphosphonates 2 act as depot forms of the parent antiviral nucleosides.

Abstract
[reaction: see text] Aryl nucleoside H-phosphonates 3 and aryl nucleoside P-acylphosphonates 4, generated in situ from the appropriate H-phosphonate 1 and acylphosphonate monoesters 2, respectively, reacted rapidly in the presence of tertiary amines to produce in high yields the extended, pyrophosphate analogues, diaryl dinucleoside phosphonate-phosphate derivatives 6. These, depending on a substituent on the alpha-carbon of the phosphonate moiety, either underwent transformation into the dinucleoside phosphonate-phosphate 7 or afforded nucleoside H-phosphonates 8 and aryl nucleoside phosphate 9.

Abstract
Genistein, the principal soy isoflavone, is a molecule of great interest as an innovative chemotherapeutic agent or as a lead-compound in anticancer drug design. To enhance intrinsic activity of genistein and to explore its pharmacophoric potential, its glycosidic derivatives were synthesized. On the basis of structural features and calculated lipophilicity coefficient (ClogP) the derivatives were classified as hydrophilic (i.e. those containing free sugar moiety) or lipophilic (i.e. those with alkylated or acylated sugar hydroxyls). The in vitro cytostatic and cytotoxic studies showed hydrophilic glycosides to be practically inactive against human cancer cell lines when compared to the free aglycone. On the contrary, lipophilic glycosides were significantly more active than the parent isoflavone although the correlation between ClogP and the activity was not clear. On the basis of GI50 and LC50 values two of the most active glycosides were found to be several times more potent in their cytostatic and cytotoxic effect than genistein. Additionally all lipophilic glycosides were revealed to exhibit different mode of action in comparison to genistein. It may suggest that these compounds do not undergo rapid biodegradation, either in culture media or inside cells, and exert their biological effects primarily as intact molecules.

Abstract
9-[(2-Hydroxyethoxy)methyl]guanine (acyclovir, 1a) and 9-[(1,3-dihydroxy-2-propoxy)methyl]guanine (DHPG, ganciclovir, 1b) were transformed to their respective tricyclic derivatives, 3-substituted 3,9-dihydro-9-oxo-5H-imidazo[1,2-a]purines 2b, 3a, and 3b. The 6-methyl-substituted compound 2b was obtained following reaction of 1b with bromoacetone. A two-step approach via 1-(2,2-diethoxyethyl) intermediates 4a,b was the most effective for the preparation of the derivatives unsubstituted in the appended ring (3a,b). The novel acyclonucleosides, in particular ganciclovir derivative 2b, proved markedly active against herpes simplex virus type 1 and 2, varicella-zoster virus, and cytomegalovirus.
