Cat. No.: HY-B0809 Purity: 99.94%
COA Handling Instructions

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.

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[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].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Western Blot Analysis[3]

Cell Line: A549 cells
Concentration: 0, 20, 100 and 500 µM
Incubation Time: 2 hours

Result: Decreased the expression of Bcl-2.
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[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male Swiss mice[1]
Dosage: 100 mg/kg
Administration: Intraperitoneal injection; daily, for 9 days
Result: Increased IL-6 and IL-10 levels and inhibited TNF-α and NO.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
