| 产品描述 | 7-(β-Hydroxyethyl)theophylline-d6is intended for use as an internal standard for the quantification of 7-(β-hydroxyethyl)theophylline by GC- or LC-MS. 7-(β-Hydroxyethyl)theophylline is a methylxanthine phosphodiesterase (PDE) inhibitor.1It reduces histamine, 5-hydroxytryptamine (5-HT), and bradykinin-induced bronchoconstriction in an anesthetized guinea pig model of bronchial asthma.2Formulations containing 7-(β-hydroxyethyl)theophylline in combination with theophylline have been used in the treatment of asthma. 1.Mizon, J., Skandrani, E., and Mizon, C.Determination of the inhibitory activity of some new substituted theophyllines on the specific phosphodiesterase of cyclic nucleotidesTherapie26(5)911-917(1971) 2.Ufkes, J.G., Leeuwin, R.S., Ottenhof, M., et al.Efficacy of theophylline and its N-7-substituted derivatives in experimentally induced bronchial asthma in the guinea-pigArch.
