Salmeterol-13C6 (xinafoate) is the 13C6 labeled Salmeterol (xinafoate). Salmeterol (GR 33343X) xinafoate is a potent and selective human β2 adrenoceptor agonist. Salmeterol shows potent stimulation of cAMP accumulation in CHO cells expressing human β2, β1 and β3 adrenoceptors with pEC50s of 9.6, 6.1, and 5.9, respectively.

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].
