uric acid Uric Acid: An oxidation product, via XANTHINE OXIDASE, of oxypurines such as XANTHINE and HYPOXANTHINE. It is the final oxidation product of purine catabolism in humans and primates, whereas in most other mammals URATE OXIDASE further oxidizes it to ALLANTOIN.. uric acid : An oxopurine that is the final oxidation product of purine metabolism.. 6-hydroxy-1H-purine-2,8(7H,9H)-dione : A tautomer of uric acid having oxo groups at C-2 and C-8 and a hydroxy group at C-6.. 7,9-dihydro-1H-purine-2,6,8(3H)-trione : An oxopurine in which the purine ring is substituted by oxo groups at positions 2, 6, and 8. | 2.36 | 2 | 0 | uric acid | Escherichia coli metabolite; human metabolite; mouse metabolite |
3-methylcholanthrene Methylcholanthrene: A carcinogen that is often used in experimental cancer studies.. 3-methylcholanthrene : A pentacyclic ortho- and peri-fused polycyclic arene consisting of a dihydrocyclopenta[ij]tetraphene ring system with a methyl substituent at the 3-position. | 1.97 | 1 | 0 | ortho- and peri-fused polycyclic arene | aryl hydrocarbon receptor agonist; carcinogenic agent |

1,7-dimethylxanthine 1,7-dimethylxanthine : A dimethylxanthine having the two methyl groups located at positions 1 and 7. It is a metabolite of caffeine and theobromine in animals. | 1.96 | 1 | 0 | dimethylxanthine | central nervous system stimulant; human blood serum metabolite; human xenobiotic metabolite; mouse metabolite |
phenobarbital Phenobarbital: A barbituric acid derivative that acts as a nonselective central nervous system depressant. It potentiates GAMMA-AMINOBUTYRIC ACID action on GABA-A RECEPTORS, and modulates chloride currents through receptor channels. It also inhibits glutamate induced depolarizations.. phenobarbital : A member of the class of barbiturates, the structure of which is that of barbituric acid substituted at C-5 by ethyl and phenyl groups. | 1.97 | 1 | 0 | barbiturates | anticonvulsant; drug allergen; excitatory amino acid antagonist; sedative |
theobromine Theobromine: 3,7-Dimethylxanthine. The principle alkaloid in Theobroma cacao (the cacao bean) and other plants. A xanthine alkaloid that is used as a bronchodilator and as a vasodilator. It has a weaker diuretic activity than THEOPHYLLINE and is also a less powerful stimulant of smooth muscle. It has practically no stimulant effect on the central nervous system. It was formerly used as a diuretic and in the treatment of angina pectoris and hypertension. (From Martindale, The Extra Pharmacopoeia, 30th ed, pp1318-9). theobromine : A dimethylxanthine having the two methyl groups located at positions 3 and 7. A purine alkaloid derived from the cacao plant, it is found in chocolate, as well as in a number of other foods, and is a vasodilator, diuretic and heart stimulator. | 1.96 | 1 | 0 | dimethylxanthine | adenosine receptor antagonist; bronchodilator agent; food component; human blood serum metabolite; mouse metabolite; plant metabolite; vasodilator agent |
1,3,7-trimethylurate 1,3,7-trimethylurate : An organic anion obtained by deprotonation of 1,3,7-trimethyluric acid.. 1,3,7-trimethyluric acid : An oxopurine in which the purine ring is substituted by oxo groups at positions 2, 6, and 8, and the nitrogens at positions 1, 3, and 7 are substituted by methyl groups. It is a metabolite of caffeine. | 1.96 | 1 | 0 | oxopurine | human blood serum metabolite; human urinary metabolite; human xenobiotic metabolite; mouse metabolite |
