| | 1-METHYLURIC ACID Usage And Synthesis |
| Chemical Properties | White to Off-White Solid | | Uses | 1-Methyluric acid, a metabolite of Theophylline, 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 | | Definition | ChEBI: An oxopurine that is 7,9-dihydro-1H-purine-2,6,8(3H)-trione substituted by a methyl group at N-1. It is one of the metabolites of caffeine found in human urine. | | 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. | | Purification Methods | Recrystallise it from H2O. Its solubility at 17.5o is 1g in 353mL of H2O. [Bergmann & Dikstein J Am Chem Soc 77 691 1955.] It has UV: max at 231 and 283nm (pH 3), and 217.5 and 292.5nm (pH >12) [Johnson Biochem J 5 133 1952].
