Description:	PD-168077 maleate is a selective dopamine D4 receptor agonist, with a Ki of 9 nM.
In Vivo:	PD-168077 (0.2-25.0 mg/kg) dose-dependently induces locomotion, which takes an unusual and characteristic ”shuffling” form with uncoordinated movements together with yawning, and episodes of myoclonic jerking; grooming, and rearing are reduced[1].
In Vitro:	PD-168077 is one of the first agents to be identified as putative selective D4 agonists. It shows >100-fold selectivity over other members of the D2-like receptor family and over their D1-like counterparts; PD-168077 shows a 20-fold selectivity over α1, and α2, a 45-fold selectivity over 5-HT1A, and a 460-fold selectivity over 5-HT2A receptors; PD-168077 evidences intrinsic activity at the D4 receptor in terms of quinpirole-like inhibition of forskolin-stimulated cAMP accumulation or stimulation of [3H]thymidine uptake in CHO cells expressing the human D4 receptor[1]. In the PD-168077-treated cell, p-CaMKII exhibits a significantly increased clustering at synaptic sites, as indicated by the enhanced colocalization with PSD-95[2].

Cat. No.	Product name	Field of application
DC73426	F17464	F17464 is a dopamine D3 receptor preferential antagonist exhibiting high affinity for human dopamine receptor subtype 3 (hD3) (Ki=0.17 nM) and 5-HT1a (Ki=0.16 nM) and a >50 fold lower affinity for the human dopamine receptor subtype 2 short and long form (hD2s/l) (Ki=8.9 and 12.1 nM, respectively). F17464 is a D3 receptor antagonist, 5-HT1a receptor partial agonist. F17464 blocks ketamine induced morphological changes, an effect D3 receptor mediated, in human dopaminergic neurons. F17464 increases dopamine release in the rat prefrontal cortex and mouse lateral forebrain-dorsal striatum and seems to reduce the effect of MK801 on % c-fos mRNA medium expressing neurons in cortical and subcortical regions. F17464 also rescues valproate induced impairment in a rat social interaction model of autism, with dose range 0.32-2.5 mg/kg i.p. in both rats and mice
DC73421	ASP4345	ASP4345 (ASP-4345) is a potent, selective positive allosteric modulator of the dopamine type 1 (D1) receptor that selectively binds to, and enhances the activity of, D1 receptors.
DC72808	UCM-1306	UCM1306 is a potent and orally active human dopamine D1 receptor allosteric modulator (PAM). UCM-1306 increases the endogenous dopamine (DA) maximal effect both in human and mouse D1 receptors. UCM-1306 is not only for improving motor symptoms but also for addressing the key comorbid cognitive impairment associated with long-term Parkinson’s disease (PD).
DC47683	Mesdopetam hemitartrate	Mesdopetam (IRL790) hemitartrate is a dopamine D3 receptor antagonist (Ki=90 nM; IC50=9.8 μM for human recombinant D3 receptor) with psychomotor stabilizing properties. Mesdopetam hemitartrate is used for the research of motor and psychiatric complications in Parkinson disease.
DC47270	(S)-Amisulpride	(S)-Amisulpride (Esamisulpride) is a potent dopamine D2/D3 receptor antagonist. (S)-Amisulpride is an antagonist at the 5-HT7 receptor with a KI of 900 nM. (S)-Amisulpride has antipsychotic and antidepressant effects.
DC46840	Mesdopetam	Mesdopetam (IRL790) is an orally active and low toxicity dopamine D3 receptor antagonist. Mesdopetam can be used for the research of Parkinson's disease (PD).
DC43970	NGB 2904 hydrochloride	NGB 2904 hydrochloride is a potent, selective, orally active and brain-penetrated antagonist of dopamine D3 receptor, with a Ki of 1.4 nM. NGB 2904 hydrochloride shows selectivity for D3 over D2, 5-HT2, α1, D4, D1 and D5 receptors (Kis=217, 223, 642, >500
DC8859	SKF38393 HCl	SKF38393 HCl is a selective dopamine D1/D5 receptor agonist.
DC5015	Rotigotine Hydrochloride	Rotigotine is dopamine D2 and D3 receptor agonist. Ki values are 13 and 0.71 nM for D2 and D3 respectively. Rotigotine also has significant affinity for 5-HT1A and adrenergic α2B receptors. Rotigotine exhibits antiparkinsonian acitivity.
DC12316	PD-168077 maleate	PD-168077 maleate is a selective dopamine D4 receptor agonist, with a Ki of 9 nM.
