Synthesis and evaluation of oligodeoxynucleotides containing 4'-C-substituted thymidines

4'-C-Hydroxymethylthymidine was converted to 4'-C-methoxymethylthymidine and 4'-C-aminomethylthymidine, which were incorporated into oligodeoxynucleotides by phosphoramidite chemistry. The modified oligonucleotides exhibit excellent hybridization and significant improvement in stability to snake venom phosphodiesterase.

4′-Epi-DNA: A DNA Mimic Containing 4′-hydroxymethyl-α-l-Xylo-Thymidine with Compact Backbone like RNA

Synthesis of C4′-epi-DNA containing 3′→ 5″ linkages is reported for the first time. Crystal structure study of the monomer indicated that though the dihedral angle O3′-C3′-C4′-C5″ in this case would be like in RNA, the sugar conformation would remain like that in DNA. The study of the effect of this backbone configuration in DNA with respect to its binding to cDNA and RNA is reported in this note.

Sugar modified nucleosides and their use for synthesis of oligonucleotides

A number of modified nucleosides are disclosed composed of modified sugar moieties which contain substituents at C1 and C4 positions, or branched substituents at C3 and C5 positions of deoxyribose or ribose. Each nucleoside is converted to or properly pro
