Beschreibung
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].
Chemische Eigenschaften
Light yellow powder
Verwenden
3-Methylxanthine is a Xanthine derivative with diuretic, cardiac stimulant and smooth muscle relaxant activities; isomeric with theobromine.They can also act as Bronchodilator.
Allgemeine Beschreibung
3-Methylxanthine, a metabolite of theophylline, was quantitated in rat plasma by a sensitive LC-MS/MS method.
l?uterung methode
Crystallise it from water. [Beilstein 26 II 263, 26 III/IV 2329.]
