| Bioactivity | Theophylline (1,3-Dimethylxanthine) is a potent phosphodiesterase (PDE) inhibitor, adenosine receptor antagonist, and histone deacetylase (HDAC) activator. Theophylline (1,3-Dimethylxanthine) inhibits PDE3 activity to relax airway smooth muscle. Theophylline (1,3-Dimethylxanthine) has anti-inflammatory activity by increase IL-10 and inhibit NF-κB into the nucleus. Theophylline (1,3-Dimethylxanthine) induces apoptosis. Theophylline (1,3-Dimethylxanthine) can be used for asthma and chronic obstructive pulmonary disease (COPD) research[1][2][3][4][5]. | ||||||||||||
| Invitro | Theophylline (1,3-Dimethylxanthine) (1-1000 µM) inhibits cAMP hydrolysis by PDE in homogenates of bronchial tissue to relax human bronchus and pulmonary arteries[1].Theophylline (1,3-Dimethylxanthine) (10 µg/mL; 24 h; eosinophils) induces apoptosis through a reduction in the antiapoptotic protein Bcl-2[2].Theophylline (1,3-Dimethylxanthine) (0-500 µM; 2 h; A549 cells) inhibits NF-κB activation, I kappa B alpha (I-κBα) degradation and decreases the level of IL-6 in a concentration-dependent manner[3].Theophylline (1,3-Dimethylxanthine) (0-1000 µM; 30 min; A549 cells) induces histone deacetylase activity to decrease inflammatory gene expression[4].
