Dacomitinib-d₁₀ dihydrochloride  (Synonyms: PF-00299804-d₁₀ dihydrochloride; PF-299804-d₁₀ dihydrochloride)

Dacomitinib-d₁₀ (dihydrochloride) is the deuterium labeled Dacomitinib dihydrochloride. Dacomitinib (PF-00299804) dihydrochloride is a specific and irreversible inhibitor of the ERBB family of kinases with IC50s of 6 nM, 45.7 nM and 73.7 nM for EGFR, ERBB2, and ERBB4, respectively[1].

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].

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