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