PD-168,077 is a drug which acts as a dopamine agonist selective for the D4 subtype, [1] [2] which is used for researching the role of D4 receptors in the brain, [3] [4] [5] particularly relating to learning and memory. [6] The propensity to induce penile erections in rats means it could be used for this also? [7]

<span class="mw-page-title-main">5-HT receptor</span> Class of transmembrane proteins

5-HT receptors, 5-hydroxytryptamine receptors, or serotonin receptors, are a group of G protein-coupled receptor and ligand-gated ion channels found in the central and peripheral nervous systems. They mediate both excitatory and inhibitory neurotransmission. The serotonin receptors are activated by the neurotransmitter serotonin, which acts as their natural ligand.

Dopamine receptor D<sub>4</sub> Protein-coding gene in the species Homo sapiens

The dopamine receptor D4 is a dopamine D2-like G protein-coupled receptor encoded by the DRD4 gene on chromosome 11 at 11p15.5.

<span class="mw-page-title-main">SKF-82,958</span> Chemical compound

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.

κ-opioid receptor Protein-coding gene in the species Homo sapiens, named for ketazocine

The κ-opioid receptor or kappa opioid receptor, abbreviated KOR or KOP for its ligand ketazocine, is a G protein-coupled receptor that in humans is encoded by the OPRK1 gene. The KOR is coupled to the G protein Gi/G0 and is one of four related receptors that bind opioid-like compounds in the brain and are responsible for mediating the effects of these compounds. These effects include altering nociception, consciousness, motor control, and mood. Dysregulation of this receptor system has been implicated in alcohol and drug addiction.

<span class="mw-page-title-main">SB-277,011-A</span> Chemical compound

SB-277,011A is a drug which acts as a potent and selective dopamine D3 receptor antagonist, which is around 80-100x selective for D3 over D2, and lacks any partial agonist activity.

5-HT<sub>1A</sub> receptor Serotonin receptor protein distributed in the cerebrum and raphe nucleus

The serotonin 1A receptor is a subtype of serotonin receptor, or 5-HT receptor, that binds serotonin, also known as 5-HT, a neurotransmitter. 5-HT1A is expressed in the brain, spleen, and neonatal kidney. It is a G protein-coupled receptor (GPCR), coupled to the Gi protein, and its activation in the brain mediates hyperpolarisation and reduction of firing rate of the postsynaptic neuron. In humans, the serotonin 1A receptor is encoded by the HTR1A gene.

Dopamine receptor D<sub>3</sub> Subtype of the dopamine receptor protein

Dopamine receptor D3 is a protein that in humans is encoded by the DRD3 gene.

<span class="mw-page-title-main">Dipropylcyclopentylxanthine</span> Chemical compound

8-Cyclopentyl-1,3-dipropylxanthine (DPCPX, PD-116,948) is a drug which acts as a potent and selective antagonist for the adenosine A1 receptor. It has high selectivity for A1 over other adenosine receptor subtypes, but as with other xanthine derivatives DPCPX also acts as a phosphodiesterase inhibitor, and is almost as potent as rolipram at inhibiting PDE4. It has been used to study the function of the adenosine A1 receptor in animals, which has been found to be involved in several important functions such as regulation of breathing and activity in various regions of the brain, and DPCPX has also been shown to produce behavioural effects such as increasing the hallucinogen-appropriate responding produced by the 5-HT2A agonist DOI, and the dopamine release induced by MDMA, as well as having interactions with a range of anticonvulsant drugs.

<span class="mw-page-title-main">Propylnorapomorphine</span> Chemical compound

N-n-Propylnorapomorphine (NPA) is an aporphine derivative dopamine agonist closely related to apomorphine. In rodents it has been shown to produce hyperactivity, stereotypy, hypothermia, antinociception, and penile erection, among other effects. Notably, its effects on locomotion are biphasic, with low doses producing inhibition and catalepsy and high doses resulting in enhancement of activity. This is likely due to preferential activation of D2/D3 autoreceptors versus postsynaptic receptors, the latter of which overcomes the former to increase postsynaptic dopaminergic signaling only with high doses.

<span class="mw-page-title-main">TAN-67</span> Chemical compound

TAN-67 (SB-205,607) is an opioid drug used in scientific research that acts as a potent and selective δ-opioid agonist, selective for the δ1 subtype. It has analgesic properties and induces dopamine release in nucleus accumbens. It also protects both heart and brain tissue from hypoxic tissue damage through multiple mechanisms involving among others an interaction between δ receptors and mitochondrial K(ATP) channels.

<span class="mw-page-title-main">A-77636</span> Chemical compound

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.

<span class="mw-page-title-main">A-68930</span> Chemical compound

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.

<span class="mw-page-title-main">ABT-724</span> Chemical compound

ABT-724 is a drug which acts as a dopamine agonist, and is selective for the D4 subtype. It was developed as a possible drug for the treatment of erectile dysfunction, although poor oral bioavailability means alternative drugs such as ABT-670 may be more likely to be developed commercially. Nonetheless, it continues to be used in scientific research into the function of the D4 receptor.

<span class="mw-page-title-main">U-69,593</span> Chemical compound

U-69,593 is a drug which acts as a potent and selective κ1-opioid receptor agonist. In animal studies it has been shown to produce antinociception, anti-inflammation, anxiolysis, respiratory depression, and diuresis, while having little effect on gastrointestinal motility. It also inhibits the peripheral, though not central secretion of oxytocin and vasopressin in rats.

<span class="mw-page-title-main">PNU-99,194</span> Chemical compound

PNU-99,194(A) (or U-99,194(A)) is a drug which acts as a moderately selective D3 receptor antagonist with ~15-30-fold preference for D3 over the D2 subtype. Though it has substantially greater preference for D3 over D2, the latter receptor does still play some role in its effects, as evidenced by the fact that PNU-99,194 weakly stimulates both prolactin secretion and striatal dopamine synthesis, actions it does not share with the more selective (100-fold) D3 receptor antagonists S-14,297 and GR-103,691.

<span class="mw-page-title-main">BP-897</span> Chemical compound

BP-897 is a drug used in scientific research which acts as a potent selective dopamine D3 receptor partial agonist with an in vitro intrinsic activity of ~0.6 and ~70x greater affinity for D3 over D2 receptors and is suspected to have partial agonist or antagonist activity in vivo. It has mainly been used in the study of treatments for cocaine addiction. A study comparing BP-897 with the potent, antagonistic, and highly D3 selective SB-277,011-A found, "SB 277011-A (1–10 mg/kg) was able to block cue-induced reinstatement of nicotine-seeking, indicating that DRD3 selective antagonism may be an effective approach to prevent relapse for nicotine. In contrast, BP 897 did not block the cue-induced reinstatement of nicotine-seeking or nicotine-taking under the FR5 schedule."

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.

<span class="mw-page-title-main">L-741,626</span>

L-741,626 is a drug which acts as a potent and selective antagonist for the dopamine receptor D2. It has good selectivity over the related D3 and D4 subtypes and other receptors. L-741,626 is used for laboratory research into brain function and has proved particularly useful for distinguishing D2 mediated responses from those produced by the closely related D3 subtype, and for studying the roles of these subtypes in the action of cocaine and amphetamines in the brain.
