Description and Uses

(S)-Pramipexole is a dopamine D_2S, D_2L, D₃, and D₄ receptor agonist (EC₅₀s = 426.58, 338.84, 2.24, and 128.82 nM, respectively, in a [³⁵S]GTPγS binding assay). It is also a partial agonist of α_2A-adrenergic receptors (α_2A-ARs; EC₅₀ = 3,548.13 nM). (S)-Pramipexole is selective for dopamine D_2-4 receptors (K_is = 954.99, 1,698.24, 12.59, 128.82 nM for for D_2S, D_2L, D₃, and D₄ receptors, respectively, in a radioligand binding assay) over D₁ and D₅ receptors (K_is = >10,000 nM for both). It prevents MPTP-induced decreases in the number of dopaminergic neurons in the substantia nigra pars compacta in common marmosets when administered at a dose of 60 μg/kg per day before, during, and after administration of MPTP. Formulations containing (S)-pramipexole have been used in the treatment of Parkinson''s disease and restless legs syndrome.

A dopamine-D2-receptor agonist. Antiparkinsonian.
