(Rac)-Rotigotine-d3 hydrochloride

(Rac)-Rotigotine-d3 hydrochloride is a deuterium labeled (Rac)-Rotigotine (hydrochloride) . (Rac)-Rotigotine hydrochloride is a racemate of Rotigotine. Rotigotine is a full agonist of dopamine receptor, a partial agonist of the 5-HT1A receptor, and an antagonist of the α2B-adrenergic receptor, with Kis of 0.71 nM, 4-15 nM, and 83 nM for the dopamine D3 receptor and D2, D5, D4 receptors, and dopamine D1 receptor.

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].
