Theophylline-d6 (1,3-Dimethylxanthine-d6) is the deuterium labeled Theophylline. Theophylline is a nonselective phosphodiesterase (PDE) inhibitor, adenosine receptor blocker, and histone deacetylase (HDAC) activator.

Stable heavy isotopes of hydrogen, carbon, and other elements have been incorporated into drug molecules, largely as tracers for quantitation during the drug development process. Deuteration has gained attention because of its potential to affect the pharmacokinetic and metabolic profiles of drugs^[1].

Shanghai Jinpan Biotech Co Ltd has not independently confirmed the accuracy of these methods. They are for reference only.
