SKF-89,145 is a drug which acts as a dopamine agonist selective for the D1 subtype. The N-desmethyl derivative SKF-89,626 is also a selective D1 agonist with similar potency and selectivity to SKF 89,145. [1]
Dopaminergic means "related to dopamine", a common neurotransmitter. Dopaminergic substances or actions increase dopamine-related activity in the brain.
Dihydrexidine (DAR-0100) is a moderately selective full agonist at the dopamine D1 and D5 receptors. It has approximately 10-fold selectivity for D1 and D5 over the D2 receptor. Although dihydrexidine has some affinity for the D2 receptor, it has functionally selective (highly biased) D2 signaling, thereby explaining why it lacks D2 agonist behavioral qualities.
SKF-38393 is a synthetic compound of the benzazepine chemical class which acts as a selective D1/D5 receptor partial agonist. It has stimulant and anorectic effects.
SKF-82,958 is a synthetic compound of the benzazepine class that acts as a D1/D5 receptor full agonist. SKF-82,958 and similar D1-like-selective full agonists like SKF-81,297 and 6-Br-APB produce characteristic anorectic effects, hyperactivity and self-administration in animals, with a similar but not identical profile to that of dopaminergic stimulants such as amphetamine. SKF-82,958 was also subsequently found to act as an agonist of ERα with negligible activity at ERβ, making it a subtype-selective estrogen.
Rotigotine, sold under the brand name Neupro among others, is a dopamine agonist of the non-ergoline class of medications indicated for the treatment of Parkinson's disease and restless legs syndrome. It is formulated as a once-daily transdermal patch which provides a slow and constant supply of the drug over the course of 24 hours.
Dopamine receptor D2, also known as D2R, is a protein that, in humans, is encoded by the DRD2 gene. After work from Paul Greengard's lab had suggested that dopamine receptors were the site of action of antipsychotic drugs, several groups, including those of Solomon H. Snyder and Philip Seeman used a radiolabeled antipsychotic drug to identify what is now known as the dopamine D2 receptor. The dopamine D2 receptor is the main receptor for most antipsychotic drugs. The structure of DRD2 in complex with the atypical antipsychotic risperidone has been determined.
Dopamine receptor D1, also known as DRD1. It is one of the two types of D1-like receptor family — receptors D1 and D5. It is a protein that in humans is encoded by the DRD1 gene.
Dopamine receptor D3 is a protein that in humans is encoded by the DRD3 gene.
SKF-83,959, a synthetic benzazepine derivative used in scientific research, acts as an agonist at the D1–D2 dopamine receptor heteromer. It behaves as a full agonist at the D1 protomer and a high-affinity partial agonist at the D2 protomer. It was further shown to act as an allosteric modulator of the sigma-1 receptor. SKF-83,959 additionally inhibits sodium channels as well as delayed rectifier potassium channels. SKF-83,959 is a racemate that consists of the R-(+)- and S-(−)-enantiomers MCL-202 and MCL-201, respectively.
6-Br-APB is a synthetic compound that acts as a selective D1 agonist, with the (R)-enantiomer being a potent full agonist, while the (S) enantiomer retains its D1 selectivity but is a weak partial agonist. (R)-6-Br-APB and similar D1-selective full agonists like SKF-81,297 and SKF-82,958 produce characteristic anorectic effects, stereotyped behaviour and self-administration in animals, with a similar but not identical profile to that of dopaminergic stimulants such as amphetamine.
A-77636 is a synthetic drug which acts as a selective D1 receptor full agonist. It has nootropic, anorectic, rewarding and antiparkinsonian effects in animal studies, but its high potency and long duration of action causes D1 receptor downregulation and tachyphylaxis, and unlike other D1 full agonists such as SKF-82,958, it does not produce place preference in animals. A-77636 partially substituted for cocaine in animal studies, and has been suggested for use as a possible substitute drug in treating addiction, but it is better known for its use in studying the role of D1 receptors in the brain.
A-68930 is a synthetic compound that acts as a selective dopamine receptor D1 agonist. It is orally active and has antidepressant and anorectic effects in animals, producing wakefulness and tachycardia, but without stimulant effects, instead producing sedation. The difference in effects between A-68930 and other D1 agonists such as SKF-82958 may be due to their differing effects on the related D5 receptor.
7-OH-DPAT is a synthetic compound that acts as a dopamine receptor agonist with reasonable selectivity for the D3 receptor subtype, and low affinity for serotonin receptors, unlike its structural isomer 8-OH-DPAT. 7-OH-DPAT is self-administered in several animal models, and is used to study its addiction effects to cocaine.
SKF-81,297 is a synthetic drug of the benzazepine chemical class that acts as a selective dopamine D1/D5 receptor full agonist, and produces a characteristic stimulant-like pattern of anorexia, hyperactivity and self-administration in animals. This profile is shared with several related drugs such as 6-Br-APB and SKF-82,958, but not with certain other D1 full agonists such as A-77,636, reflecting functional selectivity of D1 activation. Newer findings reveal that SKF-81,297 additionally acts as a partial agonist at D1-D2 receptor heteromers.
A-86929 is a synthetic compound that acts as a selective dopamine receptor D1 agonist. It was developed as a possible treatment for Parkinson's disease, as well as for other applications such as treatment of cocaine addiction, but while it had reasonable efficacy in humans it also caused dyskinesias and has not been continued. It has mainly been used as its diacetate ester prodrug adrogolide (ABT-431), which has better bioavailability.
Dinapsoline is a drug developed for the treatment of Parkinson's disease, that acts as a selective full agonist at the dopamine D1 receptor.
SKF-77,434 is a drug which acts as a selective dopamine D1 receptor partial agonist, and has stimulant and anorectic effects. Unlike other D1 agonists with higher efficacy such as SKF-81,297 and 6-Br-APB, SKF-77,434 does not maintain self-administration in animal studies, and so has been researched as a potential treatment for cocaine addiction.
CY-208,243 is a drug which acts as a dopamine agonist selective for the D1 subtype. Unlike most D1-selective agonists, it shows efficacy in animal models of Parkinson's disease.
Tavapadon is a dopamine receptor agonist which is under development for the treatment of Parkinson's disease. It is under development by Cerevel Therapeutics, which acquired tavapadon from Pfizer in 2018. It is taken by mouth.
