Description and Uses

Pramipexole (Item No. 11981) is an agonist of dopamine receptors that has applications in Parkinson’s disease and other disorders. Pramipexole is usually available as a mixture of enantiomers, with the majority of the dopamine receptor-dependent activity resulting from the (S) form. (R)-Pramipexole is an enantiomer of pramipexole that is ~100-fold less active than the (S) form as a dopamine receptor agonist. For this reason, it can be used as a negative control for the (S) form in the study of dopamine receptors. Both isoforms are antioxidants that target mitochondria to prevent apoptosis. This cytoprotective effect of (R)-pramipexole, without dopaminergic side effects, suggests utility in amyotrophic lateral sclerosis.

(R)-Pramipexole Dihydrochloride (Pramipexole EP Impurity D; Pramipexole BP Impurity D; Pramipexole USP Related Compound D) is the opposite enantiomer of Pramipexole (P700755), a dopamine-D2-receptor agonist. Dexpramipexole is a low-molecular-weight, water-soluble, orally bioavailable, renally excreted compound with linear pharmacokinetics.
