Structure of the Human Dopamine D3 Receptor in Complex with a D2/D3 Selective Antagonist
Tweaking Dopamine Reception Dopamine modulates many cognitive and emotional functions of the human brain by activating G protein–coupled receptors. Antipsychotic drugs that block two of the receptorExpand
Dopamine Agonist-Induced Yawning in Rats: A Dopamine D3 Receptor-Mediated Behavior
A specific role for the dopamine D3 receptor in behavior has yet to be elucidated. We now report that dopamine D2/D3 agonists elicit dose-dependent yawning behavior in rats, resulting in an invertedExpand
Current perspectives on selective dopamine D3 receptor antagonists as pharmacotherapeutics for addictions and related disorders
Repeated exposure to drugs of abuse produces long‐term molecular and neurochemical changes that may explain the core features of addiction, such as the compulsive seeking and taking of the drug, asExpand
The binding sites for cocaine and dopamine in the dopamine transporter overlap
Cocaine is a widely abused substance with psychostimulant effects that are attributed to inhibition of the dopamine transporter (DAT). We present molecular models for DAT binding of cocaine andExpand
Cooperative transcription activation by Nurr1 and Pitx3 induces embryonic stem cell maturation to the midbrain dopamine neuron phenotype.
Midbrain dopamine (DA) neurons play a central role in the regulation of voluntary movement, and their degeneration is associated with Parkinson's disease. Cell replacement therapies, and inExpand
The Novel Dopamine D3 Receptor Antagonist NGB 2904 Inhibits Cocaine's Rewarding Effects and Cocaine-Induced Reinstatement of Drug-Seeking Behavior in Rats
Accumulating evidence indicates that dopamine (DA) D3 receptor antagonists appear highly promising in attenuating cocaine reward and relapse in preclinical models of addiction. In the present study,Expand
PG01037, a novel dopamine D3 receptor antagonist, inhibits the effects of methamphetamine in rats
Our previous studies have shown that the selective dopamine D3 receptor antagonists SB-277011A or NGB 2904 significantly attenuate cocaine self-administration under a progressive-ratio reinforcementExpand
Yawning and hypothermia in rats: effects of dopamine D3 and D2 agonists and antagonists
RationaleIdentification of behaviors specifically mediated by the dopamine D2 and D3 receptors would allow for the determination of in vivo receptor selectivity and aide the development of novelExpand
Relationship between Conformational Changes in the Dopamine Transporter and Cocaine-Like Subjective Effects of Uptake Inhibitors
Cocaine exerts its stimulatory effect by inhibiting the dopamine transporter (DAT). However, novel benztropine- and rimcazole-based inhibitors show reduced stimulant effects compared with cocaine,Expand
Effects of selective dopaminergic compounds on a delay-discounting task
Impulsivity is widely regarded as a multidimensional trait that encompasses two or more distinct patterns of behavior, and dopaminergic systems are implicated in the expression of impulsive behaviorExpand
