theophylline monohydrate

Theophylline monohydrate (Quibron) appears to inhibit phosphodiesterase and prostaglandin production, regulate calcium flux and intracellular calcium distribution, and antagonize adenosine. Theophylline monohydrate is a natural alkaloid derivative of xanthine isolated from the plants Camellia sinensis and Coffea arabica. Physiologically, this agent relaxes the bronchial smooth muscle, produces vasodilation (except in cerebral vessels), stimulates the CNS, stimulates the cardiac muscle, induces diuresis, and increases gastric acid secretion; it may also suppress inflammation and improve contractility of the diaphragm.

Theophylline-d6 is intended for use as an internal standard for the quantification of theophylline by GC- or LC-MS. Theophylline is an inhibitor of phosphodiesterase. It is also an adenosine A1 and A2 receptor antagonist. Theophylline induces relaxation of isolated cat bronchial smooth muscle segments precontracted with acetylcholine. It inhibits ovalbumin-induced increases in bronchoalveolar lavage fluid (BALF) eosinophil infiltration in an ovalbumin-sensitized mouse model of allergic asthma. Formulations containing theophylline have been used in the treatment of asthma and chronic obstructive pulmonary disease (COPD).

Theophylline (1,3-Dimethylxanthine) sodium glycinate is a potent inhibitor of phosphodiesterase (PDE) that inhibits PDE3 activity to relax airway smooth muscle. Theophylline sodium glycinate can be used for the research of asthma and chronic obstructive pulmonary disease (COPD). Theophylline sodium glycinate is also an adenosine receptor antagonist and histone deacetylase (HDAC) activator. Theophylline sodium glycinate has anti-inflammatory activity by increasing IL-10 and inhibiting NF-κB nucleus import. Theophylline sodium glycinate induces apoptosis [1] [2] [3] [4] [5].

Theophylline (1,3-Dimethylxanthine) is a methyl xanthine derivative from tea with diuretic, smooth muscle relaxant, bronchial dilation, cardiac and central nervous system stimulant activities. Theophylline inhibits the 3', 5'-CYCLIC NUCLEOTIDE PHOSPHODIESTERASE that degrades CYCLIC AMP thus potentiates the actions of agents that act through ADENYLYL CYCLASES and cyclic AMP.
