Disclosed are oligonucleotides and oligonucleosides that include one or more modified nucleoside units. The oligonucleotides and oligonucleosides are particularly useful as antisense agents, ribozymes, aptamer, siRNA agents, probes and primers or, when hybridized to an RNA, as a substrate for RNA cleaving enzymes including RNase H and dsRNase.

The mechanism of the sulfuricacid-catalyzedacetolysis of methyl 2,3,5-tri-O-acetyl- and methyl 2,3,5-tri-O-benzoyl-L-ribofuranosides and the accompanying anomerization of both the starting material and the 1,2,3,5-tetra-O-acetyl- and 1-O-acetyl-2,3,5-tri-O-benzoyl-L-ribofuranoses formed was investigated. The progress of the reactions was followed by 1H NMR spectroscopy and the rate constants for

Seven novel alkylated or acylated analogues of hexahydropyridazine aza-galacto-fagomine (AGF) was prepared and studied as glycosidase inhibitors with the aim of increasing inhibitory potency and selectivity. The enzyme galactocerebrosidase, implicated in Krabbe disease, was found to be potently inhibited by n-butyl N2-alkylated AGF.
Synthetic nucleoside analogues characterized by a C-C anomeric linkage form a family of promising therapeutics against infectious and malignant diseases. Herein, C-nucleosides comprising structural variations at the sugar and nucleobase moieties were examined for their ability to inhibit both murine and human norovirus RNA-dependent RNA polymerase (RdRp). We have found that the combination of 4-amino-pyrrolo[2
