Description

Application

1-Methyluric acid has been used:

• for the determination of uric acid in stool samples by liquid chromatography and tandem mass spectrometry
• in turbidimetric assay of synthetic urine samples
• as a substrate for CYP1A2(cytochrome P450 family 1 subfamily A member 2) assay

Biochem/physiol Actions

1-Methyluric acid (1-U) is a major metabolite of caffeine and theophylline with antioxidant activity that protects molecules such as low density lipoproteins (LDL) from oxidative modifications. 1-Methyluric acid may be used in studies aimed at differentiating the activities of caffeine and theophylline metabolites.
