Abstract
Glycans (carbohydrate portion of glycoproteins and glycolipids) frequently exert their function through oligomeric interactions involving multiple carbohydrate units. In efforts to recapitulate the diverse spatial arrangements of the carbohydrate units, assemblies based on hybridization of nucleic acid conjugates have been used to display simplified ligands with tailored interligand distances and valences. The programmability of the assemblies lends itself to a combinatorial display of multiple ligands. Recent efforts in the synthesis and applications of such conjugates are discussed.

Abstract
A new method for the spatially defined alignment of carbohydrates on a duplex DNA scaffold is presented. The use of an N-hydroxysuccinimide (NHS)-ester phosphoramidite along with carbohydrates containing an alkylamine linker allows for on-column labeling during solid-phase oligonucleotide synthesis. This modification method during solid-phase synthesis only requires the use of minimal amounts of complex carbohydrates. The covalently attached carbohydrates are presented in the major groove of the B-form duplex DNA as potential substrates for murine type II C-type lectin receptors mMGL1 and mMGL2. CD spectroscopy and thermal melting revealed only minimal disturbance of the overall helical structure. Surface plasmon resonance and cellular uptake studies with bone-marrow-derived dendritic cells were used to assess the capability of these carbohydrate-modified duplexes to bind to mMGL receptors.

Abstract
Beta-1,3-glucans having carbohydrate-appendages (alpha-D-mannoside, N-acetyl-beta-D-glucosaminide and beta-lactoside) at the C6-position of every repeating unit can be readily prepared from curdlan (a linear beta-1,3-glucan) through regioselective bromination/azidation to afford 6-azido-6-deoxycurdlan followed by chemo-selective Cu(i)-catalyzed [3 + 2]-cycloaddition with various carbohydrate modules having a terminal alkyne. The resultant carbohydrate-appended curdlans can interact with polycytosine to form stable macromolecular complexes consistent with two polysaccharide strands and one polycytosine strand. Furthermore, these macromolecular complexes show strong and specific affinity toward carbohydrate-binding proteins (lectins). Therefore, one can utilize these carbohydrate-appended curdlans as a new family of glycoclusters.

Abstract
Nowadays, oligonucleotide-carbohydrate conjugates are used in antisense biotechnology and in the study of glycosylated DNA functioning in vitro. The application of mono- and disaccharide phosphoramidites, solid-phase supports with immobilized carbohydrates, glycosylated nucleoside phosphoramidites, and postsynthetic conjugation of reactive sugar derivatives with oligonucleotides for preparation of oligonucleotide-carbohydrate conjugates have been systematically studied. The advantages and disadvantages of these approaches are considered. Possible strategies for synthesis of glycoclusters with different topologies conjugated to DNA are discussed. Applications of oligonucleotide-carbohydrate conjugates are highlighted. Studies of interactions of glycosylated oligonucleotides with proteins and effective cell-specific delivery of oligonucleotide-carbohydrate conjugates are discussed.

Abstract
Nucleic acids bearing glycans of various structures have been under vigorous investigation in the past decade. The carbohydrate moieties of such complexes can serve as recognition sites for carbohydrate-binding proteins-lectins-and initiate receptor-mediated endocytosis. Therefore, carbohydrates can enhance cell targeting and internalization of nucleic acids that are associated with them and thus improve the bioavailability of nucleic acids as therapeutic agents. This review summarizes nucleic acid glycosylation in nature and approaches for the preparation of both non-covalently associated and covalently-linked carbohydrate-nucleic acid complexes.

Abstract
Novel deoxyribonucleotide triphosphates bearing maltose or lactose groups were synthesized as substrates for DNA polymerase. The incorporation efficiencies of these modified substrates were investigated in both primer extension reactions and PCR. The stability and conformation of saccharide-modified dsDNAs were assessed by UV absorbance melting experiments and CD analysis. Enzymatic incorporation of saccharide-modified substrates can be used for the efficient production of saccharide-modified DNAs.

Abstract
[structure: see text] A novel strategy to prepare glycopeptide-oligonucleotide conjugates bearing a glycocluster is reported. The strategy utilizes a cyclodecapeptide scaffold as a key intermediate to anchor the carbohydrate cluster and the oligonucleotide through sequential oxime bond formation. The oligonucleotide glycocluster retains the binding affinity and recognition specificity for the target sequence. Furthermore, the conjugate shows enhanced binding to the specific lectins due to the cooperative effect produced by the carbohydrate cluster.

Abstract
A novel strategy for artificial regulation system of gene expression applying the specific molecular recognition between carbohydrate and lectin is proposed. Plasmid-lactose conjugates (pActin-lactose and pGFP-lactose) prepared via diazocoupling maintained the transcription activity with T7 RNA polymerase. Gel-shift assay showed that the pActin-lactose conjugates were specifically complexed with galactose-specific lectin RCA(120) with a strong binding affinity (K(a) = 7.6 x 10(5) M(-1) per Lac-unit). The complexes were observed to form aggregates of sub-several micrometer size by means of transmission electron microscopy (TEM) and atomic force microscopy (AFM). The activities of transcription and expression of the conjugates were evaluated, respectively, on the basis of the amount of transcript of pActin and the fluorescent intensity of the expressed GFP. These activities were repressed in the presence of an increasing concentration of RCA120, and then recovered by adding lactose, lactosylceramide-containing liposomes, and lactose-carrying polymers to the conjugate-RCA120 complex. Gel-shift assay and TEM observation revealed that the aggregation form of the complex was relaxed partially in the presence of the lactose derivatives, which increased the accessibility of T7 RNA polymerase to result in the recovery of transcription activity.

Abstract
We describe herein the construction of periodically, spatially controlled glycoclusters along DNA duplexes and their cooperative lectin recognition. Site-specifically alpha-mannosylated oligodeoxynucleotide 20-mer (Man-ODN20) was synthesized via the phosphoramidite solid-phase synthesis. Alternate hybridization of the Man-ODN20 with the half-sliding complementary ODN 20-mer (hscODN20) gave an alternately prolonged Man-cluster Man-ODN20/hscODN20. The binding of the Man-cluster to FITC-labeled ConA lectin showed sigmoidal fluorescence dependency on the concentration of Man-ODN, indicating that some mannose residues along the repeating DNA duplex were cooperatively bound to ConA (apparent affinity constant: K(af)=2.4 x 10(4)M(-1) and Hill coefficient: n=3.5). The duplex of Man-ODN20 with full complementary ODN 20-mer (fcODN20) was little bound to ConA. The binding behavior of Man-ODN20/hscODN20 is compared with that of the alternately prolonged Gal-cluster Gal-ODN20/hscODN20 previously reported. Duplexes 20-mer, 40-mer, and 60-mer presenting one, two, and three periodic galactoses were also prepared by full hybridization of 20-mer beta-galactosylated oligodeoxynucleotide (Gal-ODN20) with the periodically repeating full complementary 20-mer, 40-mer, and 60-mer ODNs. RCA(120) lectin was found to little bind the 20-mer and 40-mer duplexes and to bind weakly and non-cooperatively the 60-mer duplex (K(af)=1.1 x 10(4)M(-1)). The cooperative lectin recognition of these glycoclusters in relation with the degree of association (DA) of ODN and the numbers of glycosides along the DNA duplex is discussed.

Quadruplex-forming G-rich oligonucleotide, 5'-aminoalkyl d(TGGGGT), is glycosylated with maltoheptaose to afford a novel DNA-assisted tetrasaccharide cluster motif.

Abstract
Tris-bipyridine ferrous and ruthenium complexes carrying various saccharide appendages have been investigated to develop sensory systems for monitoring saccharide-binding phenomena. Ferrous O-glycoclusters having spacer moieties inserted between saccharide appendages and the complex core showed enhanced affinities to lectins, but ferrous N-glycoclusters, in which the saccharide-appendages are directly linked to the complex core via amide linkage, had low lectin-affinities. Molecular dynamics calculation indicated that the O-glycoclusters have flexible and densely packed saccharide clusters, in contrast to the octahedrally fixed saccharide arrays of N-glycoclusters. Flexibility of saccharide clusters is essential for their enhanced affinity, probably to induce conformational change to fit the recognition sites of lectins. According to these insights, ruthenium O-glycoclusters have been designed as luminescence biosensors. The ruthenium complexes carrying alpha-manno clusters exhibited excellent affinities (IC(min) = 9.0 x 10(-)(8) M) to concanavalin A (ConA). It is suggested from conformational analysis that densely packed mannoclusters can be fit properly to the recognition site of ConA. The binding was enthalpicaly driven (deltaH degrees = -21.8 kcal/mol). This binding behavior is quite similar to that of 1-3/1-6 trimannoside to ConA. They have strongly amplified luminescence (Phi(em) = 0.15), and their luminescence intensities were changed (approximately 40%) upon binding to the specific lectins. The ruthenium glycoclusters can be a suitable sensory system for saccharide-binding phenomena.
