Dopamine receptor agonists and antagonists act on the five G protein-coupled receptors that respond to dopamine. The receptors form two groups, with D1 and D5 in the D1-like class and D2, D3 and D4 in the D2-like class. D1-like receptors stimulate adenylyl cyclase, whereas D2-like receptors inhibit it and lower cyclic adenosine monophosphate (cAMP) levels. Dopamine signaling controls movement, reward, motivation and hormone release, and is studied in Parkinson's disease and psychiatric research. Ligands here include the agonist rotigotine HCl, the D2 antagonists L-741626 and domperidone, and the D3-preferring ligand BP897.
