Descrição

Nota de análise

Nucleosides are involved in many aspects of metabolism. Analogs of nucleosides have medical application in antivirals or anticancer treatments. This application demonstrates the utility of hydrophilic interaction chromatography (HILIC) for the retention and resolution of nucleosides and analogs thereof. Elution is not solely explained by logD but by other ionic and solvophobic effects.
