1,3,7-Trimethyluric Acid-d9
|
||
1,3,7-Trimethyluric acid-d9 is intended for use as an internal standard for the quantification of 1,3,7-trimethyluric acid by GC- or LC-MS. 1,3,7-Trimethyluric acid is a derivative of uric acid and a metabolite of caffeine. It is formed from caffeine by the cytochrome P450 isoform CYP3A4. 1,3,7-Trimethyluric acid scavenges hydroxyl radicals in a cell-free assay and inhibits t-butyl hydroperoxide-induced lipid peroxidation by 56.5% in isolated human erythrocyte membranes. | |||

Paraxanthine-d6
|
||
Paraxanthine-d6 is intended for use as an internal standard for the quantification of paraxanthine by GC- or LC-MS. Paraxanthine is an active metabolite of caffeine. It is formed via N3-demethylation of caffeine by the cytochrome P450 (CYP) isoform CYP1A2. Paraxanthine is an adenosine A1 and A2 receptor antagonist. In vivo, paraxanthine increases striatal cGMP and extracellular striatal dopamine levels and locomotor activity, as well as inhibits motor depression induced by the adenosine A1 agoni... |
