Chromatography of nucleosides

Journal of Chromatography A, 1980
Abstract The chromatographic parameters affectingthe reversed-phase high-performance liquid chromatographic (HPLC) separation of major and modified nucleosides with a μBondapak C 18 column have been studied. This investigation has resulted in the HPLC separation of eighteen nucleosides in a single analysis. The parameters studied include: the mobile

Conformation of nucleosides

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1974
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 ...

Urinary nucleosides

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]

open access: possibleArchiv 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.

Pyrazolylboratozinc Complexes of Nucleosides and Nucleoside Analogues

European Journal of Inorganic Chemistry, 2003
AbstractAttachment 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 ...

The HCV NS5B Nucleoside and Non-Nucleoside Inhibitors

Clinics in Liver Disease, 2011
This article introduces one of the most diverse classes of direct-acting antivirals for hepatitis C, the nucleoside and non-nucleoside NS5B polymerase inhibitors. Through a systematic review of the published literature, we describe their structure, mechanism of action, issues with resistance, and clinical effectiveness shown in the latest clinical ...
