Overview

Product Describtion:

Paraxanthine is a metabolite of caffeine which functions as an adenosine receptor ligand and a PARP-1 inhibitor in pulmonary epithelial cells. Studies suggest that Paraxanthine is structurally similar to caffeine and possibly mediates the physiological effects of caffeine. Also Paraxanthine acts as a competitive phosphodiesterase inhibitor, which increases intracellular cAMP, activates PKA, inhibits TNF-α and leukotriene synthesis. In addition, Paraxanthine acts as a Na+/K+ ATPase enzymatic effector.

Product Application:

1,7-Dimethylxanthine has been used for the quantification of caffeine by high-performance liquid chromatography (HPLC).
