Phosphorylation of nucleosides and nucleoside analogs by mammalian nucleoside monophosphate kinases

Pharmacology & Therapeutics, 2000
Nucleoside monophosphate kinases catalyze the reversible phosphotransferase reaction between nucleoside triphosphates and monophosphates, i.e., monophosphates are converted to their corresponding diphosphate form. These enzymes play an important role in the synthesis of nucleotides that are required for a variety of cellular metabolic processes, as ...

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

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

Glycosylation of Nucleosides

The Journal of Organic Chemistry, 2016
Nucleoside O-glycosylation represents an archetypal problem in chemical selectivity, inasmuch as the nucleobase (an undesired site of reaction) is usually more nucleophilic than the hydroxyl (the desired site of reaction). Optimized reaction conditions have been developed for the efficient O-glycosylation of nucleoside hydroxyls. Both thioglycoside and
