Dopamine D2 receptor availability is linked to hippocampal–caudate functional connectivity and episodic memory

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2016
Significance Cognitive functioning depends in part on dopamine neurotransmission in the brain. Research implicates the dopamine D1 receptor family in cognitive functions linked to the prefrontal cortex, such as working memory.

Serotonergic modulators in Alzheimer's disease: a hope in the hopeless condition

open access: yesChemistry &Biodiversity, Accepted Article.
Alzheimer 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).

D2 dopamine receptor subtype-mediated hyperactivity and amphetamine responses in a model of ADHD

open access: yesNeurobiology of Disease, 2010
Low doses of psychostimulants produce beneficial behavioral effects in ADHD patients but the mechanisms underlying the response are not understood. Here we use the hyperactive mouse mutant coloboma to identify D2-like dopamine receptor subtypes that ...

Distinct roles of presynaptic dopamine receptors in the differential modulation of the intrinsic synapses of medium-spiny neurons in the nucleus accumbens

open access: yesBMC Neuroscience, 2007
Background In both schizophrenia and addiction, pathological changes in dopamine release appear to induce alterations in the circuitry of the nucleus accumbens that affect coordinated thought and motivation. Dopamine acts principally on medium-spiny GABA

Tumor suppression and improvement in immune systems by specific activation of dopamine D1-receptor-expressing neurons in the nucleus accumbens

open access: yesMolecular Brain, 2022
Recent research has suggested that the mesolimbic dopamine network that mainly terminates in the nucleus accumbens may positively control the peripheral immune system.

Reduction of dopamine D2/3 receptor binding in the striatum after a single administration of esketamine, but not R-ketamine: a PET study in conscious monkeys

open access: yesEuropean Archives of Psychiatry and Clinical Neuroscience, 2016
R-ketamine appears to be a potent, long-lasting and safer antidepressant, relative to esketamine (S-ketamine), since it might be free of psychotomimetic side effects.

Systematic Review on 1,2,3‐Oxadiazoles, 1,2,4‐Oxadiazoles, and 1,2,5‐Oxadiazoles in the Antimycobacterial Drug Discovery

open access: yesChemMedChem, EarlyView.
The review focuses on relationships of oxadiazole derivative structures and their antimycobacterial activity including target structures in mycobacteria, in vitro or in vivo pharmacokinetic parameters, and toxicity. Apart from direct antimycobacterial activity, some 1,2,4‐oxadiazole derivatives can potentiate the antimycobacterial effect of ethionamide

Towards an understanding of the pathological basis of senile depression and incident dementia: Implications for treatment

open access: yesPsychiatry and Clinical Neurosciences, Volume 76, Issue 12, Page 620-632, December 2022., 2022
Senile depression (SD) is a heterogeneous syndrome. Several clinical profiles are more likely to appear in SD than in early‐life depression, but it remains unclear whether the pathophysiology is different. The prevalence of dementia increases with aging, and the underlying pathophysiological processes in the preclinical phase begin even before ...

Preferential binding to dopamine D3 over D2 receptors by cariprazine in patients with schizophrenia using PET with the D3/D2 receptor ligand [11C]-(+)-PHNO

open access: yesPsychopharmacology, 2016
Second-generation antipsychotics occupy dopamine D2 receptors and act as antagonists or partial agonists at these receptors. While these drugs alleviate positive symptoms in patients with schizophrenia, they are less effective for treating cognitive ...

A Phase 1 Randomized Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of Single Escalating Oral Doses of Dordaviprone and the Effects of Food on the Bioavailability of Dordaviprone in Healthy Adult Subjects

open access: yesClinical Pharmacology in Drug Development, EarlyView.
Abstract Dordaviprone (ONC201) is a novel, small molecule imipridone with antitumor effects in glioma patients. This study evaluated the pharmacokinetics and safety of dordaviprone following single escalating doses (Part A), as a capsule content mixed with applesauce or Gatorade (sports drink) [Part B1]), and with or without food [Part B2].
