一般說明
1,7-Dimethyluric acid is an important metabolite of caffeine. Electrochemical oxidation of 1,7-dimethyluric acid was studied over a wide pH range of 2.2-10.3 at solid electrodes.
應用
1,7-Dimethyluric acid is the suitable reagent used for the simultaneous determination of plasma levels of theophylline and its metabolites without interference from caffeine or caffeine metabolites by HPLC.

Omeprazole has previously been shown to induce hepatic cytochrome P4501A2 activity, as evidenced by an accelerated N-3-demethylation in the 13C-[N-3-methyl]-caffeine breath test. In this study we investigated whether the inducing potency of omeprazole can be quantified by the determination of

Systemic caffeine clearance and urinary metabolite profiles were determined in 15 subjects with diverse exposure histories to cytochrome P-450 inducers (cigarette smoke) and inhibitors (oral contraceptive steroids). A correlation was observed between caffeine clearance and a urinary ratio based on

Human acetylation phenotypes were determined with caffeine (137X) as the test substance, improved by measuring urinary caffeine metabolites with a previously described HPLC method. Caffeine, 5-acetylamino-6-formylamino-3-methyluracil (AFMU), 1-methylxanthine (IX), 1-methyluric acid (IU), 1,7-dimethylxanthine (17X), and 1,7-dimethyluric acid (17U) were quantified.
