General description

1-β-d-arabinofuranosyluracil (Ara-U) is the detoxification product or metabolite of 1-β-d-arabinofuranosylcytosine (Ara-C). Uracil 1-β-D-arabinofuranoside is the human metabolite of a cytostatic agent called cytarabine (CYT).

Application

Uracil 1-β-D-arabinofuranoside may be used as a reference compound in the analysis of cytostatics and metabolites in hospital wastewater by hydrophilic interaction chromatography/tandem mass spectrometry to demonstrate its analytical possibilities and limitations. It may also be used as a standard for chemical analysis to investigate the ecotoxicity and genotoxicity of cytotoxic antineoplastic drugs, like cytarabine (CYT) and their metabolites, like uracil-1-β-d-arabinofuranoside (AraU).

Biochem/physiol Actions

1-β-D-Arabinofuranosyluracil (ara-U) is capable of inhibiting proliferation of L5178Y mouse lymphoma cells at 17 μM concentration.

[(18)F]-FMAU is a PET tracer being evaluated for imaging cell proliferation. Current multi-step procedures of [(18)F]-FMAU synthesis are time-consuming, resulting in low radiochemical yield and inconvenient applications for the clinic. We have previously reported the use of Friedel-Crafts catalysts for

A liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) assay was developed and validated for simultaneous determination of 1-(2'-deoxy-2'-fluoro-β-D-arabinofuranosyl) uracil (FAU) and its active metabolite 1-(2'-deoxy-2'-fluoro-β-D-arabinofuranosyl) 5-methyluracil (FMAU) in human plasma. FAU and FMAU were extracted from plasma samples using
