茶中的甲基黄嘌呤衍生物，具有利尿、平滑肌松弛、扩张支气管、刺激心脏和中枢神经系统的活性。

A methylxanthine derivative from tea with diuretic, smooth muscle relaxant, bronchial dilation, cardiac and central nervous system stimulant activities. Mechanistically, theophylline acts as a phosphodiesterase inhibitor, adenosine receptor blocker, and histone deacetylase activator. Theophylline is marketed under several brand names such as Uniphyl and Theochron, and it is indicated mainly for asthma, bronchospasm, and COPD.(In Vitro):Theophylline (1,3-Dimethylxanthine) (1-1000 μM) inhibits cAMP hydrolysis by PDE in homogenates of bronchial tissue to relax human bronchus and pulmonary arteries.Theophylline (1,3-Dimethylxanthine) (10 μg/mL; 24 h; eosinophils) induces apoptosis through a reduction in the antiapoptotic protein Bcl-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.Theophylline (1,3-Dimethylxanthine) (0-1000 μM; 30 min; A549 cells) induces histone deacetylase activity to decrease inflammatory gene expression.(In Vivo):Theophylline (1,3-Dimethylxanthine) (100 mg/kg; i.p.; daily, for 9 d; male Swiss mice) has anti-inflammatory activity in mice and increases IL-6 and IL-10 levels and inhibits TNF-α and NO.

Western Blot Analysis Cell Line:A549 cells Concentration:0, 20, 100 and 500 μM Incubation Time:2 hours Result:Decreased the expression of NF-κB p65 and I-κBα degradation in a concentration-dependent manner.Western Blot Analysis Cell Line:Eosinophils Concentration:10 μg/mL Incubation Time:24 hours Result:Decreased the expression of Bcl-2.

Theophylline (1,3-Dimethylxanthine) (100 mg/kg; i.p.; daily, for 9 d; male Swiss mice) has anti-inflammatory activity in mice and increases IL-6 and IL-10 levels and inhibits TNF-α and NO. Animal Model:Male Swiss mice Dosage:100 mg/kg Administration:Intraperitoneal injection; daily, for 9 daysResult:Increased IL-6 and IL-10 levels and inhibited TNF-α and NO.
