Medchemexpress LLC Theophylline | 58-55-9 | 99.9% | 1 ML
Theophylline (1,3-Dimethylxanthine) is a potent phosphodiesterase (PDE) inhibitor, adenosine receptor antagonist, and histone deacetylase (HDAC) activator. It inhibits PDE3 activity to relax airway smooth muscle. It also demonstrates anti-inflammatory activity by increasing IL-10 and inhibiting NF-κB into the nucleus. Additionally, Theophylline induces apoptosis and is utilized in research for conditions such as asthma and chronic obstructive pulmonary disease (COPD).
