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...
Frontiers | Dopamine Receptor Subtypes, Physiology and
Dopamine receptors are widely distributed within the brain where they play critical modulator roles on motor functions, motivation and drive, as well as cognition. The identification of five genes coding for different dopamine receptor subtypes, pharmacologically grouped as D1- (D1 and D5) or D2-like (D2S, D2L, D3, and D4) has allowed the demonstration of differential receptor function in
The Dopamine D5 receptor contributes to activation
Interestingly, the D5 receptor is expressed in 88% of cholinergic interneurons (CINs) while only 17% of them express the D1 receptor and none express D3 or D4 receptor 13,14. Furthermore, CINs
Dopamine D1/D5 Receptor Antagonists with Improved
Benzazepines 1 and 2 (SCH 23390 and SCH 39166, respectively) are two classical benzazepine D 1 /D 5 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.

- What are dopamine D1 and D5 receptors?
- Dopamine D1 and D5 receptors are prototypical cell-surface seven-transmembrane (TM) G protein-coupled receptors (GPCRs) mediating elevation of intracellular cAMP levels.
- 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.
- Do dopamine D1 and D2 receptors affect seizures?
- The inference from a majority of studies is that the activation of dopamine D1 receptors facilitates seizure activity, whereas activation of D2 receptors may inhibit the development of seizures.
