7-Methylxanthine (7-MX), also known as heteroxanthine, is an active metabolite of caffeine (1,3,7-trimethylxanthine) and theobromine (3,7-dimethylxanthine). [1] [2] It is a non-selective antagonist of the adenosine receptors. [1] [2] The compound may slow the progression of myopia (nearsightedness). [1] [2] It is under investigation for this ...
1,3,7-Trimethyluric acid is a minor caffeine metabolite. [5] 7-Methylxanthine is also a metabolite of caffeine. [193] [194] Each of the above metabolites is further metabolized and then excreted in the urine. Caffeine can accumulate in individuals with severe liver disease, increasing its half-life. [195]
1,3,7-Trimethyluric acid, also referred to as trimethyluric acid and 8-oxy-caffeine, is a purine alkaloid that is produced in some plants and occurs as a minor metabolite of caffeine in humans. [1] The enzymes that metabolize caffeine into 1,3,7-trimethyluric acid in humans include CYP1A2 , CYP2E1 , CYP2C8 , CYP2C9 , and CYP3A4 .
1,2,3,4-Butanetetracarboxylic acid is an organic compound with the formula HO 2 CCH 2 CH(CO 2 H)CH(CO 2 H)CH 2 CO 2 H. It is one of the simplest stable tetracarboxylic acids. The compound exists as two diastereomers, meso and the (R,R)/(S,S) pair. All are white solids. The compound is produced by oxidation of tetrahydrophthalic anhydride. [1]
1,3,5-Triaza-7-phosphaadamantane (PTA) is a chemical compound with the formula C 6 H 12 N 3 P, a product of the substitution of a nitrogen atom of hexamethylenetetramine with a phosphorus atom. It is soluble in water, methanol , trichloromethane , acetone , ethanol and DMSO , insoluble in hydrocarbon solvent. [ 1 ]
1,1,3,3-Tetramethyl-1,3-divinyldisiloxane (also referred to as tetramethyldivinyldisiloxane) is the organosilicon compound with the formula O(SiMe 2 CH=CH 2) 2. Tetramethyldivinyldisiloxane is a colorless liquid that is employed as a ligand in organometallic chemistry and also as a homogeneous catalyst. [1] The ligand is a component of Karstedt ...
[3] [4] [64] β-Phenylacetic acid is the primary urinary metabolite of phenethylamine and is produced via monoamine oxidase metabolism and subsequent aldehyde dehydrogenase metabolism. [5] Phenylacetaldehyde is the intermediate product which is produced by monoamine oxidase and then further metabolized into β-phenylacetic acid by aldehyde ...
