Conditioned increase of locomotor activity induced by haloperidol.

Dopamine antagonist drugs have profound effects on locomotor activity. In particular, the administration of the D2 antagonist haloperidol produces a state that is similar to catalepsy. In order to confirm whether the modulation of the dopaminergic activity produced by haloperidol can act as an unconditioned stimulus, we carried out two experiments in which the administration of haloperidol was repeatedly paired with the presence of distinctive contextual cues that served as a Conditioned Stimulus. Paradoxic...

Blockade of serotonin 5-HT receptors potentiates dopamine D activation-induced disruption of pup retrieval on an elevated plus maze, but has no effect on D blockade-induced one.

Appetitive aspect of rat maternal behavior, such as pup retrieval, is motivationally driven and sensitive to dopamine disturbances. Activation or blockade of dopamine D receptors causes a similar disruption of pup retrieval, which may also reflect an increase in maternal anxiety and/or a disruption of executive function. Recent work indicates that serotonin 5-HT receptors also play an important role in rat maternal behavior. Given the well-known modulation of 5-HT on the mesolimbic and mesocortical dopamine...

Dopamine guides competition for cognitive control: Common effects of haloperidol on working memory and response conflict.

Several lines of evidence suggest that dopamine modulates working memory (the ability to faithfully maintain and efficiently manipulate information over time) but its specific role has not been fully defined. Nor is it clear whether any effects of dopamine are specific to memory processes or whether they reflect more general cognitive mechanisms that extend beyond the working memory domain. Here, we examine the effect of haloperidol, principally a dopamine D receptor antagonist, on the ability of humans to ...

Effects of Olanzapine and Haloperidol on mTORC1 signaling, Dendritic Outgrowth, and Synaptic Proteins in Rat Primary Hippocampal Neurons under Toxic Conditions.

Recent studies have demonstrated that antipsychotic drugs may activate mammalian target of rapamycin complex 1 (mTORC1) signaling in neurons. However, the relationship between mTORC1 signaling activation and currently prescribed antipsychotic drugs remains incompletely understood. The purpose of this study was to determine whether alterations in the level of mTORC1 signaling occur after rat primary hippocampal neurons are treated with olanzapine and haloperidol under toxic conditions. Additionally, we inves...

Haloperidol and delirium in the ICU: the finger pointing to the moon.

Haloperidol serum concentrations in critically ill patients included in the REDUCE study.

Aripiprazole and haloperidol protect neurite lesions via reducing excessive D2R-DISC1 complex formation.

Dopamine D2 receptor (D2R) hyperactivity causes altered brain development and later produces onset of symptoms mimicking schizophrenia. It is known that D2R interacts with disrupted in schizophrenia 1 (DISC1); however, the effect of D2R-DISC1 interaction in intracellular signalling and neurite growth has not been studied. This study investigated the effect of D2R over-activation on Akt-GSK3β signalling and neurite morphology in cortical neurons. Over-activation of D2Rs caused neurite lesions, which were as...

Differential effects of typical and atypical antipsychotics on astroglial cells in vitro.

Astrocytes are glial cells that are essential for the maintenance of central nervous system functions, modulating neurotransmitters, providing metabolic, trophic and antioxidant support, and producing a wide range of cytokines to modulate the inflammatory response. These cells can be targets for antipsychotics, medications used in the treatment of neuropsychiatric disorders. In this regard, several studies have shown that antipsychotics are able to modulate peripheral cytokine release, but their effects on ...

Cyclosomatostatin- and haloperidol-induced catalepsy in Wistar rats: differential responsiveness to sleep deprivation.

Total sleep deprivation (SD) has been found to mitigate motor dysfunctions in Parkinson's disease. Apparently, the similar sensitivity of an animal model for parkinsonism would support the model's validity. Recently, we described catalepsy induced in Wistar rats by somatostatin antagonist, cyclosomatostatin (cSST); this model simulates such a disease-associated abnormality as a fall in brain somatostatin levels. To evaluate the similarity between the cSST model and Parkinson's disease, we assessed here the ...

Antipsychotic drugs for elderly patients with schizophrenia: A systematic review and meta-analysis.

Elderly patients with schizophrenia are a particularly vulnerable group often excluded from clinical trials. Currently there is no evidence-synthesis about the efficacy and safety of antipsychotics in this subgroup. We reviewed all randomized-controlled-trials, about antipsychotics in elderly schizophrenics (last search Dec 12, 2017). Pairwise meta-analyses were conducted. The primary outcome was overall symptoms. Secondary outcomes included positive symptoms, negative symptoms, response, dropouts, quality ...

Na, K-ATPase inhibition causes hyperactivity and impulsivity in mice via dopamine D2 receptor-mediated mechanism.

Hyperactivity and impulsivity are common symptoms in several psychiatric disorders. Although dysfunction of Na, K-ATPase has been reported to be associated with the psychiatric disorders, it is not clear whether inhibition of Na, K-ATPase causes behavioral effects, including hyperactivity and impulsivity, in mice. Here, we evaluated the effect of intracerebroventricular (icv) injection of ouabain, an inhibitor of Na, K-ATPase, on hyperactivity and impulsivity in mice. At seven days after icv injection, ouab...

Butanol Fraction of Olax Subscorpioidea Produces Antidepressant Effect: Evidence for the Involvement of Monoaminergic Neurotransmission.

This study sought to investigate involvement of monoaminergic mechanism in the antidepressant action of butanol fraction (BF) of Olax subscorpioidea in rodents and the bioactive principles present. Butanol fraction was evaluated for antidepressant-like effect in the tail suspension, forced swimming and open field tests. All animals were treated with BF (5, 10 & 20 mg/kg) thirty minutes prior to the tests. On the other hand, monoaminergic neurotransmission involvement was probed by pre-treating animals wit...

Validation of the xylazine/ketamine anesthesia test as a predictor of the emetic potential of pharmacological compounds in rats.

The xylazine/ketamine anesthesia test is widely used as a predictor of the emetic potential of pharmacological compounds in rats. An emetic reflex is usually triggered by the emetic center, which is populated with many different chemoreceptors. Inhibition of the α2 adrenergic receptor (α2 receptor) is involved in the initiation of the emetic reflex, and this is the key mechanism behind the xylazine/ketamine anesthesia test. In this study, we attempt to validate this test as a predictor of the emetic poten...

Intermittent administration of haloperidol after cortical impact injury neither impedes spontaneous recovery nor attenuates the efficacy of environmental enrichment.

The administration of haloperidol (HAL) once daily for 19 days after experimental traumatic brain injury (TBI) impedes recovery and attenuates the efficacy of environmental enrichment (EE). However, it is unknown how intermittent administration of HAL affects the recovery process when paired with EE. Addressing the uncertainty is relevant because daily HAL is not always warranted to manage TBI-induced agitation in the clinic, and indeed intermittent therapy may be a more common approach. Hence, the aim of t...

Assessment of sigma-1 receptor occupancy in mice with non-radiolabelled FTC-146 as a tracer.

The use of liquid chromatography coupled with mass spectrometry (LC-MS/MS) is advantageous in in-vivo receptor occupancy assays at pre-clinical drug developmental stages. Relatively, its application is effective in terms of high throughput, data reproducibility, sensitivity, and sample processing. In this perspective, we have evaluated the use of FTC-146 as a non-radiolabelled tracer to determine the sigma-1 receptor occupancy of test drugs in mice brain. Further, the brain and plasma exposures of test drug...

The discovery, SAR and biological characterization of a novel series of 6-((1H-pyrazolo4,3-bpyridin-3-yl)amino)-benzodisothiazole-3-carboxamides as positive allosteric modulators of the metabotropic glutamate receptor 4 (mGlu4).

This work describes the discovery and characterization of novel 6-((1H-pyrazolo[4,3-b]pyridin-3-yl)amino-benzo[d]isothiazolole-3-carboxamides as mGlu4 PAMs. This scaffold provides improved metabolic clearance and CYP1A2 profiles compared to previously discovered mGlu4 PAMs. From this work, 27o was identified as a potent (EC50 = 28 nM, 49% Glu Max) and selective mGlu4 PAM with an excellent rat DMPK profile (in vivo rat CLp = 3.1 mL/min/kg, t1/2 = 445 min, CYP1A2 IC50 > 30 M). 27o was also active in revers...
