Description

General description

Xanthine is a purine that can be produced in the purine metabolic pathway via different precursors:

• Guanine deamination by guanine deaminase
• Hypoxanthine conversion by xanthine oxidoreductase

Xanthine or its derivatives are naturally present in animal organs, yeast, potatoes, coffee beans, and tea.

Application

Xanthine has been used as a substrate for the determination of xanthine oxidase (XOD) inhibitory activity. It has also been used in the following systems:

• yeast culture
• human cell line culture
• recombinant viruses cloned as bacterial artificial chromosomes in Escherichia coli

Biochem/physiol Actions

Xanthine and xanthine oxidase are used to generate superoxide radicals to measure the activity of superoxide dismutase.
