PEG-Supported Synthesis of Cyclic Oligodeoxyribonucleotides

Nucleosides and Nucleotides, 1993
Abstract Cyclic oligodeoxyribonucleotides have been synthesized in satisfactory yields by an easy procedure using polyethylene glycol (PEG) as soluble supporting polymer. The present method is particularly suitable for a medium to large scale synthesis.

Meso-oligodeoxyribonucleotides.

Nucleic acids symposium series, 1993
Meso-DNAs, containing L-sugar and D-sugar in an alternate sequence as the backbone [Fig. 1, designated as LD-(dN)n], were prepared as a modificated oligonucleotides of natural- and enantio-DNA. The characteristics of meso-DNAs were analyzed, focusing on LD-(dA)n and LD-(dT)n.

Enantio-oligodeoxyribonucleotides.

Nucleic acids symposium series, 1991
As a sugar-modified oligonucleotide, a hexamer of 9-(2-deoxy-beta-L-erythro-pentafuranosyl)-9H-purin-6-amine, [L-(dAp)5dA], was synthesized by triester method. The L-hexamer was resistant to bovine spleen phosphodiesterase. UV absorption studies indicated that L-hexamer formed a complex with poly U but not with poly dT at 0 degrees C.

Structural requirements and applications of inhibitory oligodeoxyribonucleotides

Immunologic Research, 2007
Synthetic oligodeoxyribonucleotides (ODN) bearing certain sequence characteristics mimic bacterial DNA by activating B cells and dendritic cells through Toll-like receptor (TLR) 9, an event that potentiates both humoral and cell-mediated immunity. ODN sharing some of the sequence characteristics of strong stimulatory (ST-) ODN, but substituting GGG for

Phosphite Synthesis of Oligodeoxyribonucleotides

Russian Chemical Reviews, 1988
Data in the literature published between 1983 and 1986 on the synthesis of oligodeoxyribonucleotides from nucleoside derivatives of phosphorous acid are reviewed. Attention is mainly focused on the techniques employed for preparing initial monomers for condensation.

Internalization of Oligodeoxyribonucleotides by Vibrio parahaemolyticus

Antisense Research and Development, 1993
The bacterium Vibrio parahaemolyticus was tested for its ability to internalize unmodified as well as modified DNA oligomers without attempting to permeabilize the cells. These experiments were conducted to establish whether it may be feasible to employ antisense oligomers for control of gene expression in Vibrio species without heat-shocking or ...

The automated synthesis of oligodeoxyribonucleotides

Trends in Biotechnology, 1985
Abstract Progress in science is a history of the synergistic relationship between technology and theory: growth in theoretical understanding requires and initiates technological change; technological advance opens up new areas of knowledge. The history of molecular genetics is but a single illustration of this process.

Solid phase synthesis of cyclic oligodeoxyribonucleotides.

Tetrahedron Letters, 1987
Abstract The polymer supported synthesis of cyclic oligomers of deoxycytidilic acid is described, by a method based on an oligonucleotide-solid phase linkage through the amino group of the base.

Synthesis of Oligodeoxyribonucleotides Containing Oleylamine Moieties

Russian Journal of Bioorganic Chemistry, 2001
A method for directional introduction of oleylamine residues to any position of oligodeoxyribonucleotides during their automated synthesis was developed. The presence of oleylamine residues in 3'- or 5'-terminal nucleotides was shown to have no effect on the thermodynamic stability of DNA duplexes formed by such oligonucleotides and the complementary ...

Synthesis of cyclic branched oligodeoxyribonucleotides

1991
The synthesis of two cyclic branched oligonucleotides, a trimer and a tetramer of thymidylic acid, has been successfully achieved exploiting a phosphotriester-based synthetic protocol.
