Dopamine receptor D₁, also known as DRD1, is a protein that in humans is encoded by the DRD1 gene.

Function

This gene encodes the D₁ subtype of the dopamine receptor. The D₁ subtype is the most abundant dopamine receptor in the central nervous system. This G-protein-coupled receptor stimulates adenylyl cyclase and activates cyclic AMP-dependent protein kinases. D₁ receptors regulate neuronal growth and development, mediate some behavioral responses, and modulate dopamine receptor D₂-mediated events^{[citation needed]}. Alternate transcription initiation sites result in two transcript variants of this gene.

Ligands

There are a number of ligands selective for the D₁ receptors. They comprise almost exclusively of compounds derived from dihydrexidine and from the prototypical benzazepine SCH-23,390. While the benzazepines are generally highly and fully selective for the D₁ receptor over all other receptors, the dihydrexidine derivatives do not distinguish between the D₁ and D₅ receptors and therefore cannot be said to be truly selective. The benzazepines are weak partial agonists/antagonists with low intrinsic activity, whereas the dihydrexidine derivatives function as full agonists with intrinsic activity equal to or greater than that elicited by dopamine itself.

Agonists

Chemical structures of selective D₁ receptor agonists.<

• Dihydrexidine derivatives
  • A-86,929 - full agonist with 14-fold selectivity for D₁-like receptors over D₂
  • Dihydrexidine - full agonist with 10-fold selectivity for D₁-like receptors over D₂ that was being investigated for the treatment of Parkinson's disease but was discontinued due to intolerable side effects
  • Dinapsoline - full agonist with 5-fold selectivity for D₁-like receptors over D₂
  • Dinoxyline - full agonist with approximately equal affinity for D₁-like and D₂ receptors
  • Doxanthrine - full agonist with 168-fold selectivity for D₁-like receptors over D₂

• Benzazepine derivatives
  • SKF-81,297 - 200-fold selectivity for D₁ over any other receptor
  • SKF-82,958 - 57-fold selectivity for D₁ over D₂
  • SKF-38,393 - very high selectivity for D₁ with negligible affinity for any other receptor

  • 6-Br-APB - 90-fold selectivity for D₁ over D₂
• Others
  • A-68,930
  • A-77,636
  • CY-208,243 - partial agonist with moderate selectivity for D₁-like over D₂-like receptors, structurally most closely related to ergoline-based dopamine agonists like pergolide.
  • SKF-89,145
  • SKF-89,626
  • 7,8-Dihydroxy-5-phenyl-octahydrobenzo[h]isoquinoline: extremely potent, high-affinity full agonist

• • Cabergoline - weak D₁ agonism, highly selective for D₂, and various serotonin receptors
  • Pergolide - (similar to cabergoline) weak D₁ agonism, highly selective for D₂, and various serotonin receptors

Antagonists

• Benzazepine derivatives
  • SCH-23,390 - 100-fold selectivity for D₁ over D₅
  • SKF-83,959 - 7-fold selectivity for D₁ over D₅ with negligible affinity for other receptors; acts as an antagonist at D₁ but as an agonist at D₅
  • Ecopipam (SCH-39,166) - a selective D₁/D₅ antagonist that was being developed as an anti-obesity medication but was discontinued

Interactions

Dopamine receptor D1 has been shown to interact with COPG, DNAJC14 and COPG2.
