Temsirolimus-d3 (CCI-779-d3) is the deuterium labeled Temsirolimus. Temsirolimus is an inhibitor of mTOR with an IC₅₀ of 1.76 μM. Temsirolimus activates autophagy and prevents deterioration of cardiac function in animal model^[8].

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].
