Dopamine Receptor Activator

Secretoneurin, rat, a 33-amino acid polypeptide, is generated by proteolytic processing of secretogranin II (SgII). Secretoneurin, rat induces dopamine release in the rat striatum in vivo and in vitro, and it exerts a very strong chemotactic effect on monocytes and eosinophils but not on granulocytes.

DL-Dopa is a dopamine precursor. It serves as a substrate for Mushroom Tyrosinase, which oxidizes it to dopaquinone, an intermediate in the DOPA-melanin polymerization process, and this reaction can be detected at 475 nm. DL-Dopa also forms synergistic hydrophobic and π-π stacking interactions with cationic surfactants. Its binding to cetylpyridinium chloride (HY-B1464) is stronger and exhibits better thermodynamic stability than its binding to benzalkonium chloride (HY-B2232). DL-Dopa can compensate for dopamine depletion in the brain and is applicable to research related to Parkinson's disease.

N-Palmitoyl dopamine (PALDA) is a endogenous, long-chain, linear fatty acid dopamide, which is inactive on TRPV1. N-Palmitoyl dopamine displays 'entourage' effects on endovanilloids N-arachidonoyl-dopamine (NADA) and anandamide.

Quinpirole (LY 171555; (-)-LY 141865) is a D2/D3 dopamine receptor agonist and a CaV1.3 calcium channel modulator. Quinpirole normalizes dendritic spine density in dopamine-depleted striatum, upregulates the protein expression of BCL2 and GluR2, downregulates the protein expression of BAX, and delays the onset of seizures. Quinpirole enhances learning and memory, inhibits neuronal apoptosis (apoptosis), and induces anxiety-like, stereotyped, and compulsive behaviors. Quinpirole disrupts prepulse inhibition in rhesus monkeys, enhances the activity of paraventricular thalamic neurons to promote recovery from Isoflurane anesthesia, and alters the composition of the gut microbiota in rats. Quinpirole can be used in research related to dyskinesia, pain, epilepsy, and neurological disorders including anxiety disorder, obsessive-compulsive disorder, and schizophrenia.

Octodrine (2-Amino-6-methylheptane) is a central nervous stimulant that increases the uptake of dopamine and noradrenaline. Octodrine is found to increase the pain threshold, cardiac rate (positive chronotropic effect) and myocardial contractility (positive inotropic effect).

Mefexamide (ANP-297) hydrochloride is a psychostimulant psychopharmaceutical and aryloxyacetic acid derivative antidepressant with dopaminergic activity. Mefexamide hydrochloride can be used for the research of depression.

Octodrine (2-Amino-6-methylheptane) is a central nervous activator that increases the uptake of dopamine and noradrenaline. Octodrine is found to increase the pain threshold, cardiac rate (positive chronotropic effect) and myocardial contractility (positive inotropic effect).

Pirepemat (IRL752) is a corticalpreferring catecholamine- and cognition-promoting agent. Pirepemat (IRL752) is used for the study of Parkinson's disease. IRL752 is a selective enhancer of cortical dopamine, acetylcholine and norepinephrine.

2'-O-Methylisoliquiritigenin, isolated from the Arachis species, up-regulates 5-HT, NE, DA and GABA pathways, but does not put a very significant effect on ne NE pathway.

RB 101 is a blood-brain barrier-crossing prodrug as well as aminopeptidase N and neutral endopeptidase-24.11 inhibitor. RB 101 blocks enkephalin breakdown, elevates extracellular enkephalin levels and activate δ-opioid receptor and dopamine D1 receptor. RB 101 can be used for the research of pain, depressive syndromes, and diabetic neuropathy.

Dopamine-¹³C,¹⁵N (hydrochloride) is the ¹³C and ¹⁵N labeled Dopamine hydrochloride.

Docarpamine is an orally active dopamine prodrug that can be hydroxylated in the small intestine and liver to form active dopamine. Docarpamine mainly activates D1-like receptors in peripheral blood vessels to lower blood pressure and heart rate in a state of spontaneous hypertension. Docarpamine exerts a pressor and tachycardic effect by activating D1-like receptors, vasopressin V1 receptors, and α-adrenergic receptors in normal blood pressure conditions. Docarpamine can be used for research on renal vascular dilation and diuresis.

RS-51324 is an oral active antidepressant agent. RS-51324 inhibitts norepinephrine uptake and reverses of Reserpine (HY-N0480)-induced hypothermia.

BB-22 is a cannabinoid wih dopamine (DA) stimulant properties. BB-22 shows affinity to CB1 receptors with a K_i value of 0.11 nM and an EC₅₀ value of 2.9 nM.

Mefexamide (ANP-297) is a psychostimulant psychopharmaceutical and aryloxyacetic acid derivative antidepressant with dopaminergic activity. Mefexamide can be used for the research of depression.

Dopamine D3 receptor agonist 1 is a dopamine D3 Receptor agonist with a K_i value of 0.268 nM. Dopamine D3 receptor agonist 1 exhibits metabolic stability in rat liver microsomes. Dopamine D3 receptor agonist 1 can be used to study severe mental disorders comorbid with substance use disorders.

Boc-MIF-1-Am (compound 2) is a human dopamine D2 receptor enhancer (EC₅₀=17.82 nM) and is a bioconjugate of melanostatin (MIF-1) and amantadine. Boc-MIF-1-Am (200 μM) exhibited mild neurotoxicity in SH-SY5Y cells.
