3-Methylxanthine Chemical Properties,Uses,Production
Description
3-Methylxanthine is one of the metabolites of theophylline. After oral intake, approximately 36% is excreted in the urine as 3-methylxanthine, 40% as 1,3-dimethyluric acid and 17% as 1-methyluric acid. 3-methylxanthine (3MX) has been assessed as an adenosine antagonist and produces the same maximal relaxation of guinea pig tracheal muscle as does. 3MX is also used to examine conformational heterogeneity in RNA aptamers and riboswitches[1-2].
Chemical Properties
Light yellow powder
Uses
3-Methylxanthine is a Xanthine derivative with diuretic, cardiac stimulant and smooth muscle relaxant activities; isomeric with theobromine.They can also act as Bronchodilator.
Definition
ChEBI: 3-methyl-9H-xanthine is a 3-methylxanthine tautomer where the imidazole proton is located at the 9-position. It has a role as a metabolite. It is a tautomer of a 3-methyl-7H-xanthine.
Biosynthesis
As the primary intermediate of theobromine degradation, 3-methylxanthine might be degraded by A. tamarii PT-7 and other candidate isolates in the liquid culture. The accumulation of 3-methylxanthine increased along with theobromine degradation since it was detected in the liquid culture after cultivation for 24?h. Over 6 days of cultivation of A. sydowii PT-2, 3-methylxanthine was produced and increased significantly (p?<?0.05) with an increasing initial theobromine concentration, respectively, showing a linear relationship between theobromine degradation and 3-methylxanthine accumulation[3].
General Description
3-Methylxanthine, a metabolite of theophylline, was quantitated in rat plasma by a sensitive LC-MS/MS method.
Purification Methods
Crystallise it from water. [Beilstein 26 II 263, 26 III/IV 2329.]
