Dexpramipexole-d₃ dihydrochloride  (Synonyms: (R)-Pramipexole-d₃ dihydrochloride; R-(+)-Pramipexole-d₃ dihydrochloride; KNS-760704-d₃ dihydrochloride)

Dexpramipexole-d₃ ((R)-Pramipexole-d₃) dihydrochloride is the deuterium labeled Dexpramipexole. Dexpramipexole ((R)-Pramipexole) dihydrochloride is an orally active, blood-brain barrier permeable mitochondrial protective agent. Dexpramipexole dihydrochloride upregulates the expression of Parkin, PINK1, GPX4 and FSP1; binds to mitochondrial F1/Fo-ATP synthase; blocks the Na_v1.8 sodium channel; and inhibits the activation of the NLRP3 inflammasome. Dexpramipexole dihydrochloride induces mitophagy, inhibits ferroptosis, pyroptosis, apoptosis, neuroinflammation and eosinophilopoiesis; maintains mitochondrial function and redox homeostasis; reduces reactive oxygen species production; and decreases myocardial infarct size. Dexpramipexole dihydrochloride is applicable to studies on eosinophilic asthma, myocardial ischemia/reperfusion injury, sepsis-associated encephalopathy, analgesia, and more.

2. This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.

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].
