Differential Role of Active Compounds in Mitophagy and Related Neurodegenerative Diseases. Toxins (Basel) 2023; 15:toxins15030202. [PMID: 36977093 PMCID: PMC10058020 DOI: 10.3390/toxins15030202] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2023] [Revised: 02/28/2023] [Accepted: 03/03/2023] [Indexed: 03/08/2023] Open
Abstract
Neurodegenerative diseases, such as Alzheimer’s disease or Parkinson’s disease, significantly reduce the quality of life of patients and eventually result in complete maladjustment. Disruption of the synapses leads to a deterioration in the communication of nerve cells and decreased plasticity, which is associated with a loss of cognitive functions and neurodegeneration. Maintaining proper synaptic activity depends on the qualitative composition of mitochondria, because synaptic processes require sufficient energy supply and fine calcium regulation. The maintenance of the qualitative composition of mitochondria occurs due to mitophagy. The regulation of mitophagy is usually based on several internal mechanisms, as well as on signals and substances coming from outside the cell. These substances may directly or indirectly enhance or weaken mitophagy. In this review, we have considered the role of some compounds in process of mitophagy and neurodegeneration. Some of them have a beneficial effect on the functions of mitochondria and enhance mitophagy, showing promise as novel drugs for the treatment of neurodegenerative pathologies, while others contribute to a decrease in mitophagy.

Abstract
BACKGROUND/PURPOSE There is evidence for low endogenous antioxidant levels and oxidative imbalance in patients with schizophrenia. A previous open-label study with α-lipoic acid (ALA), a potent antioxidant, improved patients' negative and cognitive symptoms and markers of lipid peroxidation. Here we report the results of a randomized double-blind, placebo-controlled study to verify the response of patients with schizophrenia to adjunctive treatment with ALA (100 mg/d) in a 4-month follow-up. METHODS We conducted a 16-week, double-blind, placebo-controlled study of ALA at 100 mg/d dosages. We compared negative and positive symptoms, cognitive function, extrapyramidal symptoms, body mass index, and oxidative/inflammatory parameters between placebo and control groups. RESULTS We found no significant improvement in body mass index, cognition, psychopathology, antipsychotic adverse effects, or oxidative stress and inflammation in the experimental group compared with placebo. The whole group of patients improved in several measures, indicating a strong placebo effect in this population. A surprising finding was a significant decrease in red blood cells, white blood cells, and platelets in the group treated with ALA. CONCLUSIONS The decrease in red blood cells, white blood cells, and platelet counts requires further investigation and attention when prescribing ALA for patients with schizophrenia.

Abstract
Oxidative stress has been implicated in the pathogenesis and progression of many neurodegenerative disorders including Parkinson's disease and Alzheimer's disease. One of the major enzyme systems involved in the defense against reactive oxygen species are the tripeptide glutathione and oxidoreductase glutaredoxin. Glutathione and glutaredoxin system are very important in the brain because of the oxidative modification of protein thiols to protein glutathione mixed disulfides with the concomitant formation of oxidized glutathione during oxidative stress. Formation of Pr-SSG acts as a sink in the brain and is reduced back to protein thiols during recovery, thus restoring protein functions. This is unlike in the liver, which has a high turnover of glutathione, and formation of Pr-SSG is very minimal as liver is able to quickly quench the prooxidant species. Given the important role glutathione and glutaredoxin play in the brain, both in normal and pathologic states, it is necessary to study ways to augment the system to help maintain the protein thiol status. This review details the importance of glutathione and glutaredoxin systems in several neurodegenerative disorders and emphasizes the potential augmentation of this system as a target to effectively protect the brain during aging.

Assessment of Protective Effects of Carvacrol on Haloperidol-Induced Oxidative Stress and Genotoxicity in Human Peripheral Blood Lymphocytes. J Toxicol 2022; 2022:9565881. [PMID: 36329925 PMCID: PMC9626238 DOI: 10.1155/2022/9565881] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2022] [Accepted: 10/14/2022] [Indexed: 08/24/2023] Open
Abstract
Haloperidol is a first-generation antipsychotic drug that has several indications in a wide range of mental conditions. The extensive prescription of haloperidol is correlated with some less-known adverse effects such as genotoxicity. Carvacrol is a monoterpenoid mainly found in oregano and thyme. It has the potential to scavenge free radicals in addition to increasing antioxidant defense enzyme activities and glutathione levels. In this study, we attempted to explore the possible potential of haloperidol in inducing genotoxicity in human peripheral lymphocytes as well as the protective role of carvacrol against this effect. The lymphocytes were divided into separate groups as follows: control group (cosolvent and NS); carvacrol group (5 μM); haloperidol group (25, 50, and 100 ng/ml); haloperidol (25, 50, and 100 ng/ml) + carvacrol (5 μM); positive control (0.8 μg/ml Cisplatin). After 24 hours of treatment, we conducted a cytokinesis-Block micronucleus test and an alkaline comet assay in order to determine genetic damage. Additionally, we measured glutathione and MDA levels as the biomarkers associated with oxidative stress. Significant increases in the levels of genotoxicity biomarkers (micronucleus frequency, DNA percentage in tail and tail moment) were observed in haloperidol-treated cells. The result of our oxidative stress tests also demonstrated that haloperidol had the potential to induce oxidative stress via reducing the levels of glutathione and increasing lipid peroxidation. Treatment with carvacrol significantly decreased the genotoxic events. It can be presumed that the induction of oxidative stress by haloperidol is the critical event associated with haloperidol-mediated genotoxicity. Therefore, using carvacrol as a natural antioxidant protected human lymphocytes against haloperidol genetic damage.

Neurotoxicology 2021; 87:231-242. [PMID: 34688786 DOI: 10.1016/j.neuro.2021.10.007] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 10/12/2021] [Accepted: 10/19/2021] [Indexed: 12/14/2022]
Abstract
BACKGROUND Haloperidol is a commonly used antipsychotic drug and may increase neuronal oxidative stress associated with the side effects, including tardive dyskinesia and neurite withdraw. Autophagy plays a protective role in response to the accumulated reactive oxygen species (ROS) induced mitochondria damage. Resveratrol is an antioxidant compound having neuroprotective effects; however, it is unknown if resveratrol may stimulate autophagy and decrease mitochondria damage induced by haloperidol. HYPOTHESIS We hypothesis that resveratrol stimulates the autophagic process and protects mitochondria lesion induced by haloperidol. METHODS MitoSOX™ Red Mitochondrial Superoxide Indicator and MitoTracker™ Green FM staining were used to measure the amount of the mitochondria ROS production and mitochondria mass in human SH-SY5Y cells treated with haloperidol and/or resveratrol. Autophagic related dyes and Western blot were applied to study the autophagic process and related protein expression. Besides, tandem monomeric mRFP-GFP-LC3 was used to investigate the fusion of autophagosome and lysosome. Transmission electron microscopy was used to investigate the mitochondrial and autophagic ultrastructures with or without haloperidol and resveratrol treatment. RESULTS Haloperidol administration significantly increased mitochondria ROS and mitochondrial mass, indicating the increase of mitochondria dysfunction. Although haloperidol increased the autophagosomes and lysosome formation, the autophagosome-lysosome fusion and degradation were impaired. This was because we found an increased p62 after haloperidol treatment, an indication of autophagy incompletion. Importantly, resveratrol promoted the degradation of p62, upregulated the formation of autophagolysosome, and reversed haloperidol-induced mitochondria damage. CONCLUSION These results collectively suggest that resveratrol may be introduced as a protective compound against haloperidol-induced mitochondria impairment and aberrant autophagy.

High-protein diet and omega-3 fatty acids improve redox status in olanzapine-treated rats. Mol Cell Biochem 2020; 468:143-152. [PMID: 32206947 DOI: 10.1007/s11010-020-03718-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2019] [Accepted: 03/13/2020] [Indexed: 10/24/2022]
Abstract
The present study aimed to estimate the effects of high-protein diet (PD)-isolated whey protein and omega-3 fatty acids-docosahexaenoic and eicosapentaenoic acid on oxidative parameters of rats treated with Olanzapine (OLZ). Experiments were carried out on 8-week-old Wistar albino male rats (n = 64) weighing 200 ± 20 g. By dietary and pharmacological treatment, all animals were divided into 8 groups: 1. CTRL group; 2. CTRL + OLZ group; 3. CTRL + FA group; 4. CTRL + OLZ + FA group; 5. PD group; 6. PD + OLZ group; 7. PD + FA group; 8. PD + OLZ + FA group. After 6 weeks of pharmacological/diet treatment, all animals were sacrificed to collect blood samples and determine the biomarkers of oxidative stress. The following oxidative stress markers were measured spectrophotometrically: superoxide anion radical (O2-), hydrogen peroxide (H2O2), nitric oxide (NO-), index of lipid peroxidation measured as TBARS, reduced glutathione, catalase and superoxide dismutase. The study has shown that Olanzapine treatment was associated with increased release of pro-oxidants and diminished activity of anti-oxidant markers. Additional supplementation with PD and FA succeeded in abolishing the negative influence in most of the measured parameters. However, these beneficial impacts were stronger in the case of their separate application, which could be the practical and clinical importance of these results.

Abstract
AIM The aim of the present study was to evaluate and compare the effects of a new antipsychotic, aripiprazole (unique due to its mechanism of action), with the effects of selected antipsychotic drugs, such as quetiapine, olanzapine, clozapine, risperidone, and ziprasidone (at the final concentrations corresponding to clinically effective doses used for the treatment of acute episodes of schizophrenia) on lipid peroxidation in human plasma measured by the level of thiobarbituric acid reactive substances (TBARS), which is a marker of oxidative stress. METHODS The levels of TBARS were measured spectrophotometrically, according to the modification of the Rice-Evans method. RESULTS Our results indicate that antipsychotics at doses recommended for the treatment of acute episodes of schizophrenia may induce distinct changes in the levels of lipid peroxidation products (TBARS) in plasma. Aripiprazole had no effect on the level of a lipid peroxidation marker in plasma, although used at lower doses it showed insignificant prooxidative properties similar to clozapine. Quetiapine had the strongest antioxidant properties, contrary to prooxidative action of risperidone, ziprasidone or haloperidol, and clozapine at lower doses. Olanzapine reduced the level of TBARS in plasma only at a lower dose. CONCLUSION Antipsychotics at doses recommended for the treatment of acute episode in schizophrenia may induce the distinct changes in plasma lipid peroxidation. Aripiprazole did not induce significant changes in plasma lipid peroxidation. In further studies, the role of oxidative stress in schizophrenic patients together with their clinical symptomatology and use of antipsychotics should be taken into account.

Abstract
To apply biomarkers of oxidative stress in laboratory and field settings, an understanding of their responses to changes in physiological rates is important. The evidence is accumulating that caloric intake can increase production of reactive oxygen species and thus affect background variability of oxidative stress biomarkers in ecotoxicological testing. This study aimed to delineate effects of food intake and xenobiotics on oxidative biomarkers in Daphnia magna. Antioxidant capacity measured as oxygen radical absorbance capacity (ORAC) and lipid peroxidation assayed as thiobarbituric acid reactive substances (TBARS) were measured. Food intake was manipulated by varying food densities or by exposing the animals to chemicals inhibiting feeding rate (pharmaceutical haloperidol and pesticide lindane). Feeding rate proved to affect both protein, ORAC, and TBARS in unexposed daphnids. However, there was no significant effect of feeding rate on the protein-specific ORAC values. Both substances affected individual protein and ORAC levels and changed their relationship to feeding rate. Our results show that inhibition of feeding rate influenced the interpretation of biomarker response and further emphasize the importance of understanding (1) baseline variability in potential biomarkers due to variations in metabolic state and (2) the contribution of feeding rate on toxic response of biomarkers.

Abstract
Haloperidol (HLP) is a potent antipsychotic drug that is commonly used for the treatments of schizophrenia and bipolar disorders but has a tendency to cause adverse effects. In the present study, the cyto/genotoxic potential of clinically relevant concentrations of HLP was evaluated in human peripheral blood lymphocytes (HPBLs) as sensitive biomarkers of exposure. HLP was administered as HLP hydrochloride in the final concentrations of 5, 10 and 20 ng/ml for 4 and 24 h period. Cytotoxicity was determined using differential staining of HPBLs with acridine orange and ethidium bromide while chromosomal aberrations, micronucleus and comet assays were applied to estimate the chromosomal and DNA damage after the treatment. The results of the present study indicate that HLP is capable of inducing cyto/genotoxicity in tested cells. Present study has also confirmed the need for further cytogenetic research and regular patient monitoring to minimize the risk of any possible adverse events.

Abstract
Oxidative injury in schizophrenia can be caused by the disease itself and probably by antipsychotics treatment. The aim of the study was to establish whether there is a difference between ziprasidone, clozapine and haloperidol effect on lipid peroxidation in human plasma, measured by the level of thiobarbituric acid reactive substances (TBARS). The samples of plasma from healthy subjects were incubated with the drugs (1 and 24 h) and compared with control samples. The levels of TBARS were measured spectrophotometrically, according to the Rice-Evans method. The multifactorial variance analysis ANOVA II test showed that the differences in TBARS levels significantly depended on the studied drugs (ziprasidone 40 ng/ml, haloperidol 4 ng/ml and clozapine 350 ng/ml) (F = 3.248 p = 0.047) and (ziprasidone 139 ng/ml, haloperidol 20 ng/ml and clozapine 420 ng/ml) (F = 2.248, p = 2.9 × 10(-5)). Statistically increased levels of TBARS after 24 h incubation of plasma with ziprasidone 139 ng/ml and haloperidol 20 ng/ml (p < 0.001, p < 0.05 respectively) in comparison with control samples were observed. Clozapine did not significantly (p > 0.05) increase TBARS level in plasma in comparison with control samples. The results obtained in the study showed that ziprasidone and haloperidol contrary to clozapine induced a significant increase in plasma lipid peroxidation.

Abstract
Guinea pigs (Cavia porcellus) were treated with haloperidol (HP), and free radical (FR) and ferric reducing antioxidant power (FRAP) assays were used to determine oxidative stress levels. Furthermore, the superoxide dismutase (SOD), glutathione reductase (GR) and glutathione-S-transferase (GST) activity levels were detected and glucose levels and the reduced and oxidized glutathione (GSH/GSSG) ratio were measured in HP-treated and untreated guinea pigs. The present study demonstrated that the administration of HP causes significant oxidative stress in guinea pigs (P=0.022). In animals treated with HP, the activity of GST was significantly increased compared with a placebo (P= 0.007). The elevation of SOD and GR activity levels and increase in the levels of glutathione (GSH) in HP-treated animals were not statistically significant. In the HP-untreated animals, a significant positive correlation was observed between oxidative stress detected by the FR method and GST (r=0.88, P=0.008) and SOD (r=0.86, P= 0.01) activity levels, respectively. A significant negative correlation between the levels of plasma glucose and oxidative stress detected by the FRAP method was observed (r=−0.78, P=0.04). Notably, no significant correlations were observed in the treated animals. In the HP-treated group, two subgroups of animals were identified according to their responses to oxidative stress. The group with higher levels of plasma HP had higher enzyme activity and reactive oxygen species production compared with the group with lower plasma levels of HP. The greatest difference in activity (U/μl) between the two groups of animals was for GR.

Abstract
Extrapyramidal symptoms (EPS) are associated with antipsychotic treatment. The exact definition of the genetic variants that influence the antipsychotic induced EPS would dramatically increase the quality of antipsychotic prescriptions. We investigated this issue in a subsample of the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD). Four hundred nine manic patients were treated with antipsychotics and had complete clinical and genetic data. Outcome was an item of the Clinical Monitoring Form which scored tremors from 0 to 4 at each clinical visit. Visits were scheduled according to clinical issues, based on a naturalistic approach. A genomic inflation factor of 1.017 resulted after genetic quality control. Single SNPs GWAS (Plink) and molecular pathway GWAS were conducted (SNP ratio test, KEGG depository). No single SNP reached GWAS significance level of association. Molecular pathways related to cell survival events and lipid synthesis were significantly associated with antipsychotic induced EPS (P = 0.0009 for Hsa04512, Hsa01031, Hsa00230, Hsa04510, Hsa03320, Hsa04930, and Hsa04115; P = 0.0019 for Hsa04020 and Hsa00561). This finding was consistent with previous GWAS studies.

Abstract
OBJECTIVE Oxidative injury in schizophrenia may be caused not only by pathophysiological processes but partly also by treatment with antipsychotics. The purpose of the present study was to examine and to compare the effects of quetiapine (QUE), olanzapine (OLA) and haloperidol (HAL), at final concentrations corresponding to doses used for treatment of acute episodes of schizophrenia, on plasma lipid peroxidation in vitro, measured by the level of thiobarbituric acid-reactive substances (TBARS). METHODS Blood from 30 healthy volunteers was collected into ACD (citric acid/citrate/dextrose) solution. The drugs in form of active substances were dissolved in 0.01% dimethyl sulfoxide, added to plasma at the final concentrations [QUE (175 and 275 ng/ml), OLA (20 and 40 ng/ml), HAL (4 and 20 ng/ml)] and incubated for 1 and 24 h at 37 °C. The level of TBARS was measured spectrophotometrically (according to the Rice-Evans method, 1991). RESULTS The comparative study in vitro showed that QUE causes a decrease in the TBARS level in plasma, whereas HAL increases the plasma TBARS level. After 24 h of incubation of plasma with QUE or HAL (at lower and higher concentrations),thedifferences in TBARS levels between the drugs were significant (p = 5.9 × 10⁻⁴, p = 2.2 × 10⁻⁵, respectively). CONCLUSION QUE and OLA, contrary to the prooxidative action of HAL, did not induce oxidative stress; moreover, QUE has antioxidant properties.

Abstract
There is evidence that reactive oxygen species (ROS) are involved in the pathophysiology of psychiatric disorders such as schizophrenia. Indirect biochemical alterations of ROS formation have been shown for patients treated with antipsychotics as well as for untreated patients. Only one study measured directly the ROS formation after treatment with antipsychotics by using electron spin resonance spectroscopy. The aim of the present examination was to demonstrate the effects of haloperidol, clozapine and olanzapine in concentrations of 18, 90 and 180 μg/mL on the formation of ROS in the whole blood of rats by using electron spin resonance spectroscopy after incubation for 30 min. To test the protective capacity of vitamin C we incubated the highest concentration of each drug with vitamin C (1 mM). Under all treatment conditions, olanzapine led to a significantly higher formation of ROS compared with control conditions, whereas in the cases of haloperidol and clozapine the two higher concentrations induced a significantly enhanced formation of ROS. Vitamin C reduced the ROS production of all drugs tested and for haloperidol and clozapine the level of significance was reached. Our study demonstrated that antipsychotics induce the formation of ROS in the whole blood of rats, which can be reduced by the application of vitamin C.

Abstract
Neurotransmitter receptors play a key role in most research on antipsychotic drugs, but little is known about the effects of these drugs on the plasma membrane in the central nervous system. Therefore, we investigated whether chlorpromazine (CPZ), a typical phenothiazine antipsychotic drug, affects the plasma membrane integrity in the rat brain, and if so, whether these membrane alterations can be prevented by dietary supplementation with vitamin E, which has been shown to be an antioxidant and also a membrane-stabilizer. Leakage of [(18)F]2-fluoro-2-deoxy-D-glucose ([(18)F]FDG)-6-phosphate from rat striatal slices and decrease in 1,6-diphenyl-1,3,5-hexatriene fluorescence anisotropy were used as indexes for plasma membrane permeabilization and fluidization, respectively. CPZ induced leakage of [(18)F]FDG-6-phosphate from striatal slices, and the leakage was delayed in the vitamin E-supplemented group compared to that in the normal diet group. The decrease in plasma membrane anisotropy induced by CPZ was significantly attenuated by vitamin E supplementation. Chronic treatment with alpha-phenyl-N-tert-butyl nitrone, a free radical scavenger, had no effect on CPZ-induced plasma membrane permeabilization, and the treatment with CPZ did not induce lipid peroxidation. CPZ can reduce plasma membrane integrity in the brain, and this reduction can be prevented by vitamin E via its membrane-stabilizing properties, not via its antioxidant activity.

Abstract
The use of antipsychotic drugs is limited by their tendency to produce extrapyramidal movement disorders such as tardive dyskinesia and parkinsonism. In previous reports it was speculated that extrapyramidal side effects associated with the butyrophenone neuroleptic agent haloperidol (HP) could be caused in part by the neurotoxic effect of its pyridinium metabolite (HPP(+)). Although both HPP(+) and HP have been shown to induce neurotoxic effects such as loss of cell membrane integrity, no information exists about the difference in the neurotoxic potency, especially in the potency to induce plasma membrane damage, between these two agents. In the present study, we compared the potency of the interaction of HPP(+) and HP with the plasma membrane integrity in the rat brain. Membrane permeabilization (assessed as [(18)F]2-fluoro-2-deoxy-d-glucose-6-phosphate release from brain slices) and fluidization (assessed as the reduction in the plasma membrane anisotropy of 1,6-diphenyl 1,3,5-hexatriene) were induced by HPP(+) loading (at >or=100 microM and >or=10 microM, respectively), while comparable changes were induced only at a higher concentration of HP (=1 mM). These results suggest that HPP(+) has a higher potency to induce plasma membrane damage than HP, and these actions of HPP(+) may partly underlie the pathogenesis of HP-induced extrapyramidal side effects.

Abstract
Tardive syndromes are characterized by abnormal involuntary movements that occur after prolonged exposure to drugs that block dopamine receptors. The prevalence and incidence of tardive syndromes are much higher in elderly individuals, and the number of elderly patients receiving antipsychotics has been increasing. This article summarizes the clinical phenomenology, pathophysiology, epidemiology, and treatment of these disorders in elderly individuals.

Abstract
Tardive dyskinesia has been and continues to be a significant problem associated with long-term antipsychotic use, but its pathophysiology remains unclear. In the last 10 years, preclinical studies of the administration of antipsychotics to animals, as well as clinical studies of oxidative processes in patients given antipsychotic medications, with and without tardive dyskinesia, have continued to support the possibility that neurotoxic free radical production may be an important consequence of antipsychotic treatment, and that such production may relate to the development of dyskinetic phenomena. In line with this hypothesis, evidence has accumulated for the efficacy of antioxidants, primarily vitamin E (alpha-tocopherol), in the treatment and prevention of tardive dyskinesia. Early studies suggested a modest effect of vitamin E treatment on existing tardive dyskinesia, but later studies did not demonstrate a significant effect. Because evidence has continued to accumulate for increased oxidative damage from antipsychotic medications, but less so for the effectiveness of vitamin E, especially in cases of long-standing tardive dyskinesia, alternative antioxidant approaches to the condition may be warranted. These approaches may include the use of antioxidants as a preventive measure for tardive dyskinesia or the use of other antioxidants or neuroprotective drugs, such as melatonin, for established tardive dyskinesia.

Abstract
To review the interaction between melatonin and the dopaminergic system in the hypothalamus and striatum and its potential clinical use in dopamine-related disorders in the central nervous system. Medline-based search on melatonin-dopamine interactions in mammals. Melatonin. the hormone produced by the pineal gland at night. influences circadian and seasonal rhythms, most notably the sleep-wake cycle and seasonal reproduction. The neurochemical basis of these activities is not understood yet. Inhibition of dopamine release by melatonin has been demonstrated in specific areas of the mammalian central nervous system (hypothalamus, hippocampus, medulla-pons, and retina). Antidopaminergic activities of melatonin have been demonstrated in the striatum. Dopaminergic transmission has a pivotal role in circadian entrainment of the fetus, in coordination of body movement and reproduction. Recent findings indicate that melatonin may modulate dopaminergic pathways involved in movement disorders in humans. In Parkinson patients melatonin may, on the one hand, exacerbate symptoms (because of its putative interference with dopamine release) and, on the other, protect against neurodegeneration (by virtue of its antioxidant properties and its effects on mitochondrial activity). Melatonin appears to be effective in the treatment of tardive dyskinesia. a severe movement disorder associated with long-term blockade of the postsynaptic dopamine D2 receptor by antipsychotic drugs in schizophrenic patients. The interaction of melatonin with the dopaminergic system may play a significant role in the nonphotic and photic entrainment of the biological clock as well as in the fine-tuning of motor coordination in the striatum. These interactions and the antioxidant nature of melatonin may be beneficial in the treatment of dopamine-related disorders.

Abstract
We have investigated the potential of high-performance liquid chromatography (HPLC) coupled to mass spectrometry (MS) to determine enrichments of citrulline as a marker for in vivo nitric oxide (NO) production in brain tissue. The analysis of citrulline as the butyl ester derivative was evaluated using two types of ionization: electron spray ionization (ESI) and atmospheric pressure chemical ionization (APCI). APCI-MS appeared to be more suitable for determination of citrulline than ESI-MS, because the ion intensity of the protonated molecule ion [M+H]+, m/z 232, of citrulline in the former was about twelve times higher than in the latter. The chromatography was carried out on a reversed C8 column with the mobile phase consisting of 15% acetonitrile: 85% H2O: 0.2% acetic acid (v/v). The calibration curve had good linearity within the concentration range investigated (5 ng to 500 ng/ml). The limit of determination was estimated to be ca. 1 ng/ml of standard solution. The method was applied to the analysis of citrulline in the brain dialysate obtained from rat after perfusion of the striatum with haloperidol (HP, 0.1 mM). It is concluded that APCI-MS in combination with HPLC can be successfully applied to determination of citrulline in brain tissue, thus providing a useful tool for assessment of in vivo NO production.

Abstract
Haloperidol (HP), a dopamine receptor antagonist, is cytotoxic to mouse clonal hippocampal HT22 cells in a concentration-dependent manner and causes cell death by oxidative stress. The addition of HP to HT22 cells led to an increase in intracellular peroxides and a time-dependent drop in the intracellular glutathione levels. HP-induced oxidative cell death was prevented by the pineal hormone melatonin, its precursor N-acetyl serotonin, and most effectively by vitamin E (alpha-tocopherol). These antioxidants inhibited the intracellular peroxide accumulation and stabilized the glutathione content of HT22 cells after the challenge with HP. At the molecular level, HP specifically induced the DNA binding activity and the transcriptional activity of the redox-sensitive transcription factor NF-kappaB. This enhanced NF-kappaB activity could be blocked by the neuroprotective antioxidants. The specific suppression of NF-kappaB by its inhibitor IkappaBalpha partially protected the cells against HP, indicating that the activation of NF-kappaB may be involved in HP-induced oxidative cell death in vitro.
