D(3) dopamine receptor is a protein that in humans is encoded by the DRD3 gene.[1][2]

This gene encodes the D3 subtype of the dopamine receptor. The D3 subtype inhibits adenylyl cyclase through inhibitory G-proteins. This receptor is expressed in phylogenetically older regions of the brain, suggesting that this receptor plays a role in cognitive and emotional functions. It is a target for drugs which treat schizophrenia, drug addiction, and Parkinson's disease [3] . Alternative splicing of this gene results in multiple transcript variants that would encode different isoforms, although some variants may be subject to nonsense-mediated decay (NMD).[2]

D3 agonists like 7-OH-DPAT, pramipexole, and rotigotine, among others, display antidepressant effects in rodent models of depression.[4][5]



Numerous non-selective prescription drugs bind to the D3 receptor, notably including some of the newer dopamine agonists used for Parkinson's disease such as pramipexole and ropinirole, but these also bind to D2 and lack the strong receptor type and subtype selectivity that some of the following research compounds afford:


  • 8-OH-PBZI (cis-8-Hydroxy-3-(n-propyl)-1,2,3a,4,5,9b-hexahydro-1H-benz[e]indole)
  • PF-219,061 ((R)-3-(4-Propylmorpholin-2-yl)phenol): >1000-fold functional (efficiacy) selectivity over D2[6]
  • compound R,R-16: 250x binding selectivity over D2[7]
  • trans-N-{4-[4-(2,3-Dichlorophenyl)-1-piperazinyl]cyclohexyl}-3-methoxybenzamide, full agonist, > 200-fold binding selectivity over D4, D2, 5-HT1A, and α1-receptors[8]
  • (-)-7-{[2-(4-Phenylpiperazin-1-yl)ethyl]propylamino}-5,6,7,8-tetrahydronaphthalen-2-ol[9]
  • BP-897: partial agonist [10]
  • FAUC 73
  • FAUC 460: partial agonist, outstanding affinity and selectivity[11]
  • FAUC 346: partial agonist, subtype selective[12]
  • PD-128,907
  • compound 12: partial agonist, Ki = 0.41nM, 800x binding selectivity over D2[13]
  • piribedil[14]


  • [15]
  • FAUC 365, silent antagonist, subtype selective[12]
  • compound 29 [16]
  • Nafadotride
  • NGB-2904[17]
  • SB-277011-A, selective D3 antagonist, 80x selectivity over D2 with no partial agonist effects, used in drug addiction research as a potential therapy for addiction to several different drugs
  • Domperidone - D2 and D3 antagonist
