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. [2]
In chemistry, 3,3,4,4-tetramethyltetrahydrofuran-2,5-dione is a heterocyclic compound with the formula C 8 H 12 O 3, or (CH 3) 2 (COC 2 COO)(CH 3) 2. It is a white crystalline solid with a pungent camphoraceous odor. [1] The compound is also called 3,3,4,4-tetramethyloxolane-2,5-dione (its IUPAC name) or 3,3,4,4-tetramethylsuccinic anhydride ...

Caffeine citrate, sold under the brand name Cafcit among others, is a medication used to treat a lack of breathing in premature babies. [5] Specifically it is given to babies who are born at less than 35 weeks or weigh less than 2 kilograms (4.4 lb) once other causes are ruled out. [6]
In nonpolar solvents, a range between 0.2 and 0.6 kcal/mol has been estimated, but in polar solvents the axial conformer may be more stable. [21] The two conformers interconvert rapidly through nitrogen inversion ; the free energy activation barrier for this process, estimated at 6.1 kcal/mol, is substantially lower than the 10.4 kcal/mol for ...
ATD has many names in sports supplements including: 1,4,6 etiollochan-dione, 3, 17-keto-etiochol-triene, androst-1,4,6-triene-3,17-dione and many others. These all refer to CAS# 633-35-2. ATD may cause a positive test for the anabolic steroid Boldenone, of which it is a possible metabolite and production contaminant. ATD is also prohibited in ...
