Abstract The dipole moments of a series of model pyrimidine nucleosides were determined experimentally. Comparison was made between the experimental values and those vectorially calculated as a function of nucleoside conformation. This analysis alone does not permit the unequivocal determination of the conformation of the nucleoside in solution, but ...

Recent progress for the synthesis of selected carbocyclic nucleosides.
Future Medicinal Chemistry, 2015Nucleoside analogs are extremely useful for the development of therapeutic agents to control viral diseases and cancer. Among the numerous modifications on the nucleoside skeleton, replacement of the oxygen of the furanose ring by a CH2 group resulted in

Mass Spectrometry Reviews, 1998
The methods of analysis, origins, and clinical significance of urinary nucleosides are reviewed through 1997. Structures, chromatographic and mass spectral data and references to the clinical literature are presented for each of the 57 nucleosides currently identified in normal and pathogenic human urine samples. Data from the HPLC separation and GC/MS

Synthesis and Antiviral Evaluation of Novel Cyclopropyl Nucleosides, Phosphonate Nucleosides and Phosphonic Acid Nucleosides [PDF]
Archiv der Pharmazie, 2006 AbstractNovel phenyl‐branched cyclopropyl nucleosides, phosphonates, and phosphonic acid analogues were designed and synthesized as potential antiviral agents. Coupling of the mesylate 10 with natural bases (U, T, C, A) and desilylation/hydrolysis afforded a series of novel cyclopropyl nucleosides 15–18.

Radical route for the alkylation of purine nucleosides at C6 via Minisci reaction.
Organic Letters, 2014A highly regioselective Minisci reaction with the decarboxylative alkylation of purine nucleosides under mild conditions was developed. With 5 mol % AgNO3 as a catalyst and (NH4)2S2O8 as an oxidant, a series of purine nucleosides including ribosyl ...

Pyrazolylboratozinc Complexes of Nucleosides and Nucleoside Analogues
European Journal of Inorganic Chemistry, 2003AbstractAttachment of deprotonated nucleosides or of alkylated nucleobases, as their analogues, to zinc was achieved by condensation reactions between TpZn‐OH complexes and nucleobase derivatives. Pyrazolylboratozinc complexes with derivatives of uracil, thymine, guanine, xanthine and hypoxanthine were obtained and characterized by structure ...
