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