Dopamine Receptor Subtypes, Physiology and Pharmacology: New Ligands and Concepts in Schizophrenia

Frontiers in Pharmacology, 2020
Dopamine receptors are widely distributed within the brain where they play critical modulator roles on motor functions, motivation and drive, as well as cognition.

Cocaine Sensitization: Modulation by Dopamine D2 Receptors [PDF]

Cerebral Cortex, 2002
Repeated administration of cocaine progressively increases drug-induced locomotor activity. This study examined the role of dopamine D(1)- and D(2)-like receptors in the medial prefrontal cortex (mPFC) in mediating these sensitized behaviors. For initiation experiments, animals received bilateral intra-mPFC injections of either saline, the D(1)-like ...

Contribution of Addictovigilance data to assess adverse‐events linked to psychoactive substances in children and adolescents

British Journal of Clinical Pharmacology, EarlyView.
Aims We sought to characterize adverse events and deaths associated with the use of psychoactive substances in children and adolescents. Methods Two French Addictovigilance databases were analysed: spontaneous reports and deaths over the period 2016–2021, in subjects aged 10–<18 years. An unsupervised classification was implemented on consumption data (

Effects on turning of microinjections into basal ganglia of D1 and D2 dopamine receptors agonists and the cannabinoid CB1 antagonist SR141716A in a rat Parkinson's model

Neurobiology of Disease, 2004
Brain cannabinoid CB1 receptors are expressed in neural areas that contribute to movement such as basal ganglia, where they co-localize with dopamine D1 and D2 receptors.

Deciphering the skeletal interoceptive circuitry to control bone homeostasis

BMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

Pharmacological blockade of dopamine D1- or D2-receptor in the prefrontal cortex induces attentional impairment in the object-based attention test through different neuronal circuits in mice

Molecular Brain, 2021
Dopamine is a key neurotransmitter that regulates attention through dopamine D1 and D2-receptors in the prefrontal cortex (PFC). We previously developed an object-based attention test (OBAT) to evaluate attention in mice.

Serotonergic Modulators in Alzheimer's Disease: A Hope in the Hopeless Condition

Chemistry &Biodiversity, EarlyView.
ABSTRACT Alzheimer's disease (AD) is the main cause of dementia worldwide. AD is a progressive brain neurodegenerative disease due to genetic and environmental factors that induce a progressive accumulation of intracellular hyperphosphorylated tau protein and extracellular amyloid protein (Aβ).

Ethnomedicinal Uses, Phytochemistry, Pharmacological Activities, and Toxicology of the Subfamily Gomphrenoideae (Amaranthaceae): A Comprehensive Review

Chemistry &Biodiversity, EarlyView.
ABSTRACT The subfamily Gomphrenoideae is composed of about 480 accepted species, many of which have been historically used as medicinal plants, reason why they have been studied in terms of chemical profile, biological activity, and safety. This review consolidates the advances in research on this subfamily over the past 47 years, emphasizing its ...

Synthesis and Biological Characterization of 4,4‐Difluoro‐3‐(phenoxymethyl)piperidine Scaffold as Dopamine 4 Receptor (D4R) Antagonist in vitro Tool compounds

ChemMedChem, EarlyView.
The work presents details of the efforts to design and characterize novel D4 inhibitors. A new 4,4‐difluoropiperidine ether series that confers improved potency and selectivity for D4 versus the other dopamine receptor subtypes is identified. Extensive structure‐activity relationship around this privileged group identifies the key structural changes to

Kappa-opioid receptor signaling in the striatum as a potential modulator of dopamine transmission in cocaine dependence

Frontiers in Psychiatry, 2013
Cocaine addiction is accompanied by a decrease in striatal dopamine signaling, measured as a decrease in dopamine D2 receptor binding as well as blunted dopamine release in the striatum. These alterations in dopamine transmission have clinical relevance,
