7-(beta-Hydroxyethyl)theophylline-d6

7-(beta-Hydroxyethyl)theophylline-d6 is intended for use as an internal standard for the quantification of 7-(beta-hydroxyethyl)theophylline (Cay-28372) by GC- or LC-MS. 7-(beta-Hydroxyethyl)theophylline is a methylxanthine phosphodiesterase (PDE) inhibitor. It reduces histamine, 5-hydroxytryptamine (5-HT), and bradykinin-induced bronchoconstriction in an anesthetized guinea pig model of bronchial asthma. Formulations containing 7-(beta-hydroxyethyl)theophylline in combination with theophylline have been used in the treatment of asthma.Formal Name: 3,7-dihydro-7-(2-hydroxyethyl)-1,3-di(methyl-d3)-1H-purine-2,6-dione.
