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].
