| Bioactivity | Pramipexole dihydrochloride is a selective and blood-brain barrier (BBB) penetrant dopamine D2-type receptor agonist, with Kis of 2.2 nM, 3.9 nM, 0.5 nM and 1.3 nM for D2-type receptor, D2, D3 and D4 receptors, respectively. Pramipexole dihydrochloride can be used for the research of Parkinson's disease (PD) and restless legs syndrome (RLS)[1][2][3]. |
| Invitro | Pramipexole shows a low binding affinity for D1-type receptor, with an IC50 of >50,000 nM[1].Pramipexole dihydrochloride (0.01-10 μM; 72 hours) produces dose-dependent increases of dendritic arborization and soma size[3].Pramipexole dihydrochloride attenuates levodopa-induced toxicity in mesencephalic cultures, suggests that pramipexole may be cytoprotective to dopamine neurons in tissue culture[4]. |
| In Vivo | Pramipexole dihydrochloride (0.25-1 mg/kg; i.p.) significantly reduces the infarction volume in animals[5].Pramipexole dihydrochloride improves neurological recovery[5].Pramipexole dihydrochloride prevents ischemic cell death via mitochondrial pathways in ischemic stroke[5].
