A Dopamine D3 and D2 Receptor Agonist, Pramipexole

Pramipexole dihydrochloride, which is a dopamine agonist, has selective affinity for dopamine receptors of the D2 subfamily (D2, D3, D4), with a 7-10 fold greater affinity for D3 than for D2 receptor subtypes; affinity for the D4 receptor subtype is 17-fold less than for D3 receptors. For your reference, [D4337] is a key synthetic building block of pramipexole dihydrochloride.
