Dopamine D1/D5 receptor antagonists with improved
Abstract Benzazepines 1 and 2 (SCH 23390 and SCH 39166, respectively) are two classical benzazepine D1/D5 antagonists, with Ki values 1.4 and 1.2 nM, respectively. Compound 2 has been in human clinical trials for a variety of diseases, including schizophrenia, cocaine addition, and obesity.
Dopamine Agonists - StatPearls - NCBI Bookshelf
Dopamine agonists, such as ropinirole, are the first-line treatment for restless legs syndrome, while bromocriptine is given for neuroleptic malignant syndrome. Dopamine agonists are also prescribed to counteract dopamine antagonist-induced hyperprolactinemia. Dopamine agonists are used in patients with Parkinson disease.

Mechanisms of D1/D2-like dopaminergic agonist
Rotigotine ([-]2-(N-propyl-N-2-thienylethylamino)-5-hydroxytetraline) is a dopamine agonist with an affinity for all dopamine receptors (D1 to D5), which when delivered daily as a single dose

- What are dopamine D1 D5 and D2 receptors in the prefrontal cortex?
- The distribution and major functions of dopamine D1–D5 receptors in the prefrontal cortex and their implication for disorders. On the other hand, dopamine D2 receptors in the prefrontal cortex are expressed on both excitatory pyramidal neurons and inhibitory interneurons [8, 26, 29, 140, 141, 142].
- Is halobenzazepine a dopamine receptor antagonist?
- James.bourne@med.monash.edu.au SCH 23390, the halobenzazepine (R)- (+)-7-chloro-8-hydroxy-3-methyl-1-phenyl-2,3,4,5- tetrahydro-1H-3-benzazepine, is a highly potent and selective dopamine D1-like receptor antagonist with a K (i) of 0.2 and 0.3 nM for the D1 and D5 dopamine receptor subtypes, respectively.
- Is SCH 23390 the first selective dopamine D1-like receptor antagonist?
- Bourne JA. SCH 23390: the first selective dopamine D1-like receptor antagonist. CNS Drug Rev. 2001;7:399–414. Waddington JL, O’Boyle KM. Drugs acting on brain dopamine receptors: a conceptual re-evaluation five years after the first selective D1 antagonist. Pharmacol Ther. 1989;43:1–52. Arnsten AF, Cai JX, Murphy BL, Goldman-Rakic PS.
- Are non-catecholamine D1/D5 receptor agonists useful?
- Non-catecholamine D1/D5 receptor agonists can dissociate Gs protein signaling from β-arrestin recruitment, and may be useful for treating motor impairment in Parkinson’s disease and cognitive impairment in neuropsychiatric disorders [15, 216].
- What are dopamine D1 D5 & D2 receptors in the ventral tegmental area?
- Table 9. Major functions of dopamine D1–D5 receptors in the ventral tegmental area (VTA) and their implication for disorders. In contrast, D2 receptors in the VTA are involved in modulating the response to rewarding and aversive stimuli.
- What are D1 and D2 dopamine receptor subtypes?
- Within this dynamic neural nucleus, both D1- and D2-like dopamine receptor subtypes orchestrate indispensable functions, with alterations in their equilibrium implicated in neurodegenerative and neuropsychiatric pathologies, such as Parkinson’s disease, Huntington’s disease, schizophrenia, and addiction [2, 36, 91, 92, 93].
