Neuroprotective effects of Si-based hydrogen-producing agent on 6-hydroxydopamine-induced neurotoxicity in juvenile mouse model. Behav Brain Res 2024; 468:115040. [PMID: 38723675 DOI: 10.1016/j.bbr.2024.115040] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 05/02/2024] [Accepted: 05/03/2024] [Indexed: 05/26/2024]
Abstract
Neurotoxins have been extensively investigated, particularly in the field of neuroscience. They induce toxic damage, oxidative stress, and inflammation on neurons, triggering neuronal dysfunction and neurodegenerative diseases. Here we demonstrate the neuroprotective effect of a silicon (Si)-based hydrogen-producing agent (Si-based agent) in a juvenile neurotoxic mouse model induced by 6-hydroxydopamine (6-OHDA). The Si-based agent produces hydrogen in bowels and functions as an antioxidant and anti-inflammatory agent. However, the effects of the Si-based agent on neural degeneration in areas other than the lesion and behavioral alterations caused by it are largely unknown. Moreover, the neuroprotective effects of Si-based agent in the context of lactation and use during infancy have not been explored in prior studies. In this study, we show the neuroprotective effect of the Si-based agent on 6-OHDA during lactation period and infancy using the mouse model. The Si-based agent safeguards against the degradation and neuronal cell death of dopaminergic neurons and loss of dopaminergic fibers in the striatum (STR) and ventral tegmental area (VTA) caused by 6-OHDA. Furthermore, the Si-based agent exhibits a neuroprotective effect on the length of axon initial segment (AIS) in the layer 2/3 (L2/3) neurons of the medial prefrontal cortex (mPFC). As a result, the Si-based agent mitigates hyperactive behavior in a juvenile neurotoxic mouse model induced by 6-OHDA. These results suggest that the Si-based agent serves as an effective neuroprotectant and antioxidant against neurotoxic effects in the brain, offering the possibility of the Si-based agent as a neuroprotectant for nervous system diseases.

Abstract
Oxidative stress is a key contributing factor in the complex degenerating cascade in Parkinson's disease. The inhibition of MAO-B affords higher dopamine bioavailability and stops ROS formation. The incorporation of hydroxy and methoxy groups in the arylhydrazone moiety of a new series of 1,3-disubstituted benzimidazole-2-thiones could increase the neuroprotective activity. In vitro safety evaluation on SH-SY5Y cells and rat brain synaptosomes showed a strong safety profile. Antioxidant and neuroprotective effects were evaluated in H2O2-induced oxidative stress on SH-SY5Y cells and in a model of 6-OHDA-induced neurotoxicity in rat brain synaptosomes, where the dihydroxy compounds 3h and 3i demonstrated the most robust neuroprotective and antioxidant activity, more pronounced than the reference melatonin and rasagiline. Statistically significant MAO-B inhibitory effects were exerted by some of the compounds where again the catecholic compound 3h was the most potent inhibitor similar to selegiline and rasagiline. The most potent antioxidant effect in the ferrous iron induced lipid peroxidation assay was observed for the three catechols-3h and 3j, 3q. The catecholic compound 3h showed scavenging capability against superoxide radicals and antioxidant effect in the iron/deoxyribose system. The study outlines a perspective multifunctional compound with the best safety profile, neuroprotective, antioxidant and MAO-B inhibiting properties.

Abstract
OBJECTIVE Acute pancreatitis (AP), a disorder of global importance, has a growing incidence and prevalence, particularly in the western world. Its complications include pseudo-cysts and chronic pancreatitis. Pramipexole (PMX), a D2/3 receptor selecting agonist used in Parkinsonism, has reported anti-inflammatory effects lately. PURPOSE Exploring the potential curative role of PMX in an l-arginine-induced acute pancreatitis rat model besides a possible mechanistic pathway. METHODS Rats were divided randomly into three groups: control, l-arginine, and "l-arginine + PMX". 7 days after AP induction, rats decapitated and estimated for serum amylase, lipase, glucose, pancreatic inflammatory mediators "toll-like receptor-4, nuclear factor- kappa B p65 ,serum tumor necrosis factor-α, NLRP3 inflammasome, caspase-1, interleukin-1 beta, oxidative biomarkers "malondialdehyde, myeloperoxidase, nitrite/nitrate, reduced glutathione, and the apoptotic marker "caspase-3", with pancreatic histopathological changes. RESULTS L-arginine mediated AP proved by elevated serum lipase and amylase, pancreatic inflammatory, oxidative and apoptotic markers with infiltration of inflammatory cells using hematoxylin and eosin stain. PMX improved all these adverse signs of AP greatly. CONCLUSION PMX might be considered as an innovative therapy for AP due to its remarkable antioxidant, anti-apoptotic, and anti-inflammatory effects, which are attributed to the suppression of the NLRP3 inflammasome and its downstream inflammatory cytokines.

Abstract
Oxidative stress and chronic inflammation have a role in developing neurodegenerative diseases such as Parkinson’s disease (PD) and inflammatory movement disorders such as rheumatoid arthritis that affect millions of populations. In searching for antioxidant and anti-inflammatory molecules from natural sources that can counteract neurodegenerative diseases and arthritis, the flavonoid-rich extract of Diplotaxis harra (DHE) was selected based on its in vitro antioxidant and anti-inflammatory activities. DHE could inhibit the inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expressions in the lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages from 100% to the level of 28.51 ± 18.67 and 30.19 ± 5.00% at 20 μg/mL, respectively. A TLC bioautography of DHE fractions using 1,1-diphenyl-2-picryl-hydrazyl radical (DPPH) led to the isolation of a major antioxidant compound which was identified by X-ray diffraction analysis as isorhamnetin-3-O-β-D-glucoside (IR3G). IR3G also exhibited a potent anti-inflammatory activity, particularly by suppressing the upregulation of iNOS expression, similar to that of dexamethasone (DEX) at 10 μM to the level of 35.96 ± 7.80 and 29.34 ± 6.34%, respectively. Moreover, IR3G displayed a strong neuroprotectivity (>60% at 1.0−4−1.0−3 μM) against 6-hydroxydopamine (6-OHDA)-challenged SHSY5Y neuroblastoma, an in vitro model of dopaminergic neurons for Parkinson’s disease (PD) research. Accordingly, the in vivo anti-Parkinson potentiality was evaluated, where it was found that IR3G successfully reversed the 6-OHDA-induced locomotor deficit in a zebrafish model. A study of molecular docking and molecular dynamic (MD) simulation of IR3G and its aglycone isorhamnetin (IR) against human acetylcholine esterase (AChE), monoamine oxidase B (MAO-B), and Polo-like kinase-2 (PLK2) was performed and further outlined a putative mechanism in modulating neurodegenerative diseases such as PD. The free radical scavenging, anti-inflammatory through anti-iNOS and anti-COX-2 expression, and neuroprotective activities assessed in this study would present partial evidence for the potentiality of D. harra-derived IR3G as a promising natural therapeutic agent against neurodegenerative diseases and inflammatory arthritis. Finally, a biphasic HPTLC method was developed to estimate the biomarker IR3G in D. harra quantitatively.

Neuroprotective Effects of Estradiol plus Lithium Chloride via Anti-Apoptosis and Neurogenesis Pathway in In Vitro and In Vivo Parkinson's Disease Models. PARKINSONS DISEASE 2021; 2021:3064892.

Abstract
Few pharmaceutical agents for slowing Parkinson's disease (PD) progression existed, especially for perimenopause females. The current general medications are mostly hormone replacement therapy and may have some side effects. Therefore, there is an urgent need for a novel treatment for PD. This study examined the possibility of estradiol plus lithium chloride (LiCl), one of the metal halides used as an alternative to salt. We showed that the combination of LiCl and estradiol could enhance neurogenesis proteins GAP-43 and N-myc in the human neuronal-like cells. We also further confirmed the neurogenesis activity in zebrafish. LiCl and LiCl plus estradiol could enhance 6-OHDA-induced upregulation of TGase-2b and Rho A mRNA expression. Besides, LiCl plus estradiol showed a synergic effect in anti-apoptotic activity. LiCl plus estradiol protected SH-SY5Y cells and zebrafish against 6-OHDA-induced damage on neurons than LiCl or estradiol alone groups via p-P38, p-Akt, Bcl-2, and caspase-3 cascade. The potential for developing this combination as a candidate treatment for PD is discussed.

Abstract
An insult can trigger a protective response or even cell death depending on different factors that include the duration and magnitude of the event and the ability of the cell to activate protective intracellular signals, including inflammatory cytokines. Our previous work showed that the treatment of Lister Hooded rat retinal cell cultures with 50 ng/mL phorbol 12-myristate 13-acetate (PMA), a protein kinase C activator, increases the survival of retinal ganglion cells (RGCs) kept in culture for 48 h after axotomy. Here we aim to analyze how PMA modulates the levels of TNF-α and IL-1β (both key inflammatory mediators) and the impact of this modulation on RGCs survival. We hypothesize that the increase in RGCs survival mediated by PMA treatment depends upon modulation of the levels of IL-1β and TNF-α. The effect of PMA treatment was assayed on cell viability, caspase 3 activation, TNF-α and IL-1β release and TNF receptor type I (TNFRI) and TNF receptor type II (TNFRII) levels. PMA treatment increases IL-1β and TNF-α levels in 15 min in culture and increases the release of both cytokines after 30 min and 24 h, respectively. Both IL-1β and TNF-α levels decrease after 48 h of PMA treatment. PMA treatment also induces an increase in TNFRII levels while decreasing TNFRI after 24 h. PMA also inhibited caspase-3 activation, and decreased ROS production and EthD-1/calcein ratio in retinal cell cultures leading to an increase in cell viability. The neutralization of IL-1β (anti-IL1β 0,1ng/mL), the neutralization of TNF-α (anti-TNF-α 0,1ng/mL) and the TNF-α inhibition using a recombinant soluble TNFRII abolished PMA effect on RGCs survival. These data suggest that PMA treatment induces IL1β and TNF-α release and modulation of TNFRI/TNFRII expression promoting RGCs survival after axotomy.

Abstract
Parkinson's disease (PD) is a neurodegenerative disorder characterized by degeneration of dopaminergic neurons. Motor features such as tremor, rigidity, bradykinesia and postural instability are common traits of PD. Current treatment options provide symptomatic relief to the condition but are unable to reverse disease progression. The conventional single-target therapeutic approach might not always induce the desired effect owing to the multifactorial nature of PD. Hence, multitarget strategies have been proposed to simultaneously target multiple proteins involved in the development of PD. Herein, we provide an overview of the pathogenesis of PD and the current pharmacotherapies. Furthermore, rationales and examples of multitarget approaches that have been tested in preclinical trials for the treatment of PD are also discussed.

Abstract
Parkinson’s disease (PD), a common adult-onset neurodegenerative disorder with complex pathological mechanisms, is characterized by the degeneration of dopaminergic nigrostriatal neurons. The present study demonstrated that the herbal medicines Hepad 1 and 2 protected against 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced dopaminergic neurotoxicity in C57BL/6 mice and SH-SY5Y cells. Hepad 1 and 2 remarkably alleviated the enhanced expression of pro-inflammatory cytokines (tumor necrosis factor-α, interleukin-6, inducible nitric oxide synthase, cyclooxygenase-2, macrophage-1, and phosphorylated iκB-α) and apoptotic signals (Bcl-2-associated X protein, caspase-3, and poly [ADP-ribose] polymerase-1). Additionally, Hepad reduced MPTP-induced oxidative damage by increasing the expression of anti-oxidant defense enzymes (superoxide dismutase and glutathione S-transferase) and downregulating the levels of nicotinamide adenine dinucleotide phosphate oxidase 4. This study also showed that the neuroprotective effects of Hepad include anti-inflammatory, anti-apoptotic, and anti-oxidative properties, in addition to activation of the protein kinase B, extracellular-signal-regulated kinase, and c-Jun N-terminal kinase signaling pathways. Furthermore, oral administration of Hepad 1 and 2 attenuated the death of tyrosine hydroxylase-positive substantia nigra neurons that was induced by 20 mg/kg MPTP. Therefore, our results suggest that Hepad 1 and 2 are useful for treating PD and other disorders associated with neuro-inflammatory, neuro-apoptotic, and neuro-oxidative damage.

Development of Microplatforms to Mimic the In Vivo Architecture of CNS and PNS Physiology and Their Diseases. Genes (Basel) 2018; 9:genes9060285. [PMID: 29882823 PMCID: PMC6027402 DOI: 10.3390/genes9060285] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2018] [Revised: 05/28/2018] [Accepted: 05/31/2018] [Indexed: 12/16/2022] Open
Abstract
Understanding the mechanisms that govern nervous tissues function remains a challenge. In vitro two-dimensional (2D) cell culture systems provide a simplistic platform to evaluate systematic investigations but often result in unreliable responses that cannot be translated to pathophysiological settings. Recently, microplatforms have emerged to provide a better approximation of the in vivo scenario with better control over the microenvironment, stimuli and structure. Advances in biomaterials enable the construction of three-dimensional (3D) scaffolds, which combined with microfabrication, allow enhanced biomimicry through precise control of the architecture, cell positioning, fluid flows and electrochemical stimuli. This manuscript reviews, compares and contrasts advances in nervous tissues-on-a-chip models and their applications in neural physiology and disease. Microplatforms used for neuro-glia interactions, neuromuscular junctions (NMJs), blood-brain barrier (BBB) and studies on brain cancer, metastasis and neurodegenerative diseases are addressed. Finally, we highlight challenges that can be addressed with interdisciplinary efforts to achieve a higher degree of biomimicry. Nervous tissue microplatforms provide a powerful tool that is destined to provide a better understanding of neural health and disease.

Abstract
Microfluidic devices enable novel means of emulating neurodegenerative disease pathophysiology in vitro. These organ-on-a-chip systems can potentially reduce animal testing and substitute (or augment) simple 2D culture systems. Reconstituting critical features of neurodegenerative diseases in a biomimetic system using microfluidics can thereby accelerate drug discovery and improve our understanding of the mechanisms of several currently incurable diseases. This review describes latest advances in modeling neurodegenerative diseases in the central nervous system and the peripheral nervous system. First, this study summarizes fundamental advantages of microfluidic devices in the creation of compartmentalized cell culture microenvironments for the co-culture of neurons, glial cells, endothelial cells, and skeletal muscle cells and in their recapitulation of spatiotemporal chemical gradients and mechanical microenvironments. Then, this reviews neurodegenerative-disease-on-a-chip models focusing on Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis. Finally, this study discusses about current drawbacks of these models and strategies that may overcome them. These organ-on-chip technologies can be useful to be the first line of testing line in drug development and toxicology studies, which can contribute significantly to minimize the phase of animal testing steps.

Abstract
Parkinson’s disease (PD) is one of the most common neurodegenerative disorders where oxidative stress and mitochondrial dysfunction have been implicated as etiological factors. Mitochondria are the major producers of reactive oxygen species (ROS) that can have damaging effects to cellular macromolecules leading to neurodegeneration. The most compelling evidence for the role of mitochondria in the pathogenesis of PD has been derived from toxicant-induced models of parkinsonism. Over the years, epidemiological studies have suggested a link between exposure to environmental toxins such as pesticides and the risk of developing PD. Data from human and experimental studies involving the use of chemical agents like paraquat, diquat, 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine, rotenone and maneb have provided valuable insight into the underlying mitochondrial mechanisms contributing to PD and associated neurodegeneration. In this review, we have discussed the role of mitochondrial ROS and dysfunction in the pathogenesis of PD with a special focus on environmental agent-induced parkinsonism. We have described the various mitochondrial mechanisms by which such chemicals exert neurotoxicity, highlighting some landmark epidemiological and experimental studies that support the role of mitochondrial ROS and oxidative stress in contributing to these effects. Finally, we have discussed the significance of these studies in understanding the mechanistic underpinnings of PD-related dopaminergic neurodegeneration.

Abstract
Parkinsonism is a progressive motor disease that affects 1.5 million Americans and is the second most common neurodegenerative disease after Alzheimer’s. Typical neuropathological features of Parkinson’s disease (PD) include degeneration of dopaminergic neurons located in the pars compacta of the substantia nigra that project to the striatum (nigro-striatal pathway) and depositions of cytoplasmic fibrillary inclusions (Lewy bodies) which contain ubiquitin and α-synuclein. The cardinal motor signs of PD are tremors, rigidity, slow movement (bradykinesia), poor balance, and difficulty in walking (Parkinsonian gait). In addition to motor symptoms, non-motor symptoms that include autonomic and psychiatric as well as cognitive impairments are pressing issues that need to be addressed. Several different mechanisms play an important role in generation of Lewy bodies; endoplasmic reticulum (ER) stress induced unfolded proteins, neuroinflammation and eventual loss of dopaminergic neurons in the substantia nigra of mid brain in PD. Moreover, these diverse processes that result in PD make modeling of the disease and evaluation of therapeutics against this devastating disease difficult. Here, we will discuss diverse mechanisms that are involved in PD, neuroprotective and therapeutic strategies currently in clinical trial or in preclinical stages, and impart views about strategies that are promising to mitigate PD pathology.

Pramipexole-Induced Hypothermia Reduces Early Brain Injury via PI3K/AKT/GSK3β pathway in Subarachnoid Hemorrhage rats. Sci Rep 2016; 6:23817.

Abstract
Previous studies have shown neuroprotective effects of hypothermia. However, its effects on subarachnoid hemorrhage (SAH)-induced early brain injury (EBI) remain unclear. In this study, a SAH rat model was employed to study the effects and mechanisms of pramipexole-induced hypothermia on EBI after SAH. Dose-response experiments were performed to select the appropriate pramipexole concentration and frequency of administration for induction of mild hypothermia (33–36 °C). Western blot, neurobehavioral evaluation, Terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) and Fluoro-Jade B (FJB) staining were used to detect the effects of pramipexole-induced hypothermia on SAH-induced EBI, as well as to study whether controlled rewarming could attenuate these effects. Inhibitors targeting the PI3K/AKT/GSK3β pathway were administered to determine whether the neuroprotective effect of pramipexole-induced hypothermia was mediated by PI3K/AKT/GSK3β signaling pathway. The results showed that intraperitoneal injection of pramipexole at 0.25 mg/kg body weight once per 8 hours was found to successfully and safely maintain rats at mild hypothermia. Pramipexole-induced hypothermia ameliorated SAH-induced brain cell death, blood-brain barrier damage and neurobehavioral deficits in a PI3K/AKT/GSK3β signaling-dependent manner. Therefore, we may conclude that pramipexole-induced hypothermia could effectively inhibit EBI after SAH in rats via PI3K/AKT/GSK3β signaling pathway.

Abstract
The myeloid cell leukemia 1 (Mcl(-1)) is an anti-apoptotic member of the Bcl-2 family, which plays an essential role in protecting cells against apoptosis. The expression pattern and potential roles of Mcl(-1) in Parkinson's diseases (PD) are still unknown. In this study, our results indicated that 1-methyl-4-phenylpyridinium (MPP+) treatment augmented the expression of Mcl(-1) at both messenger RNA (mRNA) and protein levels in a dose-dependent manner in SH-SY5Y cells. Moreover, we observed increased phosphorylation of Elk-1at Ser383 as well as nuclear translocation of Elk-1 in exposure to MPP+ treatment. Importantly, the elevated expression of Mcl(-1) induced by MPP+ was abolished by knockdown of Elk-1. It was also found that inhibition of Mcl(-1) by small RNA transfection exacerbates MPP + -induced LDH release after 48 h incubation. In addition, Hoechst 33,258 nuclear staining results demonstrated that silence of Mcl(-1) induced a significant increase in apoptosis in cells when compared with the control condition. Mechanistically, the levels of cleaved Caspase3 and PARP were elevated in MPP+ treated cells, which was exacerbated by knockdown of Mcl(-1). These findings suggest that Mcl(-1) might be a potential therapeutic target for PD treatment.

Abstract
We investigated the effects of pramipexole, a potent dopamine receptor D2/D3 agonist, on light-induced retinal damage in mice, H2O2-induced retinal pigment epithelium ARPE-19 cell injury in humans, and hydroxyl radical scavenging activity in a cell-free system. Pramipexole (0.1 and 1 mg/kg body weight) was orally administered to mice 1 h before light exposure (5000 lux, 2 h). Electrophysiological and morphologic studies were performed to evaluate the effects of the pramipexole on light-induced retinal damage in mice. Pramipexole significantly prevented the reduction of the a- and b-wave electroretinogram (ERG) amplitudes caused by light exposure in a dose-dependent manner. In parallel, damage to the inner and outer segments (IS/OS) of the photoreceptors, loss of photoreceptor nuclei, and the number of Tdt-mediated dUTP nick-end labeling (TUNEL)-positive cells in the outer nuclear layer (ONL) caused by light exposure were notably ameliorated by pramipexole. Additionally, pramipexole suppressed H2O2-induced ARPE-19 cell death in vitro in a concentration-dependent manner. The effect of pramipexole was significant at concentrations of 10(-6) M or higher. Pramipexole also significantly prevented H2O2-induced activation of caspases-3/7 and the intracellular accumulation of reactive oxygen species (ROS) in a concentration-dependent manner ranging from 10(-5) to 10(-3) M. Furthermore, pramipexole increased the scavenging activity toward a hydroxyl radical generated from H2O2 in a Fenton reaction. Our results suggest that pramipexole protects against light-induced retinal damage as an antioxidant and that it may be a novel and effective therapy for retinal degenerative disorders, such as dry age-related macular degeneration.

Abstract
Dopamine agonists are highly effective as adjunctive therapy to levodopa in advanced Parkinson's disease and have rapidly gained popularity as a monotherapy in the early stages of Parkinson's disease for patients less than 65-70 years old. In the latter case, dopamine agonists are about as effective as levodopa but patients demonstrate a lower tendency to develop motor complications. However, dopamine agonists lose efficacy over time and the number of patients remaining on agonist monotherapy decreases to less than 50% after 3 years of treatment. Thus, after a few years of treatment the majority of patients who started on dopamine agonists will be administered levodopa, in a combined dopaminergic therapy, in order to achieve a better control of motor symptoms.

Abstract
OBJECTIVES Parkinson's disease (PD) is the most common neurodegenerative disease in humans, and an abundance of evidence has implicated apoptosis signaling pathways in the neurodegeneration of PD. The purpose of this study was to assess the role of B-cell lymphoma 2 (Bcl-2)-associated athanogene 5 (BAG5) protein, which was previously confirmed to play an important role in the pathogenesis of PD, in the regulation of apoptosis induced by 1-methyl-4-phenyl-pyridinium (MPP(+)) in PC12 cells. METHODS PC12 cells were treated with MPP(+) for 48 hours to induce apoptosis, and activation of Bcl-2, Bcl-xl, and caspase 3 was measured by western blot. RESULTS The upregulation of BAG5 in PC12 cells inhibited apoptosis and increased the expression of anti-apoptotic proteins, including Bcl-2 and Bcl-xl, after MPP(+) treatment. In addition, downregulation of BAG5 in PC12 cells enhanced apoptosis and decreased the expression of these proteins after MPP(+) treatment. DISCUSSION The data suggest that BAG5 inhibits MPP(+)-induced apoptosis through both endogenous and mitochondria-mediated pathways of apoptosis. Through this mechanism, the upregulation of BAG5 levels may occur through its anti-apoptotic activity in PD.

Abstract
OBJECTIVES AND METHODS To clarify the effects of a non-ergot dopamine agonist pramipexole on levodopa-induced abnormal dopamine metabolism in the parkinsonian model, we examined striatal changes in dopamine and its metabolites after repeated administration of pramipexole and/or levodopa using 6-hydroxydopamine-lesioned hemi-parkinsonian mice. Moreover, the effects of pramipexole on dopamine-semiquinones were also accessed using an in vitro dopamine-semiquinone generating system to elucidate its neuroprotective property against dopamine quinone-induced neurotoxicity that appears as dopamine neuron-specific oxidative stress. RESULTS Combined administration of pramipexole (0.5 or 1 mg/kg/day, 7 days) selectively suppressed the levodopa-induced (50 mg/kg/day) increase of striatal dopamine turnover in the parkinsonian side, but not in the non-lesioned side. In addition to the antioxidant properties previously reported, it was clarified that pramipexole scavenged dopamine-semiquinones generated in a dose-dependent manner either in simultaneous incubation or post-incubation. DISCUSSION The neurotoxicity of dopamine quinones that appear as dopaminergic neuron-specific oxidative stress has recently been known to play a role in the pathogenesis of Parkinson's disease and neurotoxin-induced parkinsonism. Therefore, the present results revealed that pramipexole possesses neuroprotective effects against abnormal dopamine metabolism in excessively levodopa-administered parkinsonian brains and against cytotoxic dopamine quinones generated from excess dopamine, preventing consequently dopaminergic neuronal damage induced by excess dopamine or levodopa.

Abstract
Enhanced oxidative stress is implicated in the pathogenesis of Parkinson's disease. The catecholaminergic neurotoxin 6-hydroxydopamine (6-OHDA) induces the production of reactive oxygen species (ROS), leading to neuronal cell death. On the other hand, apomorphine, a dopamine D1/D2 receptor agonist and known as a potent antioxidant, has been reported to have a neuroprotective effect. In the present study, we investigated the effect of apomorphine on 6-OHDA-induced apoptotic cell death using the human dopaminergic neuroblastoma cell line, SH-SY5Y. The co-treatment of cells with apomorphine significantly attenuated 6-OHDA-induced ROS generation, the phosphorylation of c-Jun N-terminal kinase (JNK), DNA fragmentation and subsequent apoptotic cell death. In addition, pretreatment with apomorphine for 24 h and the following concomitant treatment enhanced the protective effects against 6-OHDA-induced toxicity except for the attenuation of JNK phosphorylation. We also demonstrated that pretreatment alone with apomorphine for 24 h prior to the exposure confers resistance against 6-OHDA-induced cell toxicity. These findings suggested that apomorphine acts principally as a radical scavenger to suppress the level of ROS and ROS-stimulated apoptotic signaling pathway, whereas the other mechanisms might be involved in the protective effects.

Synthesis of 19-substituted geldanamycins with altered conformations and their binding to heat shock protein Hsp90. Nat Chem 2013; 5:307-14. [PMID: 23511419 DOI: 10.1038/nchem.1596] [Citation(s) in RCA: 59] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2012] [Accepted: 02/04/2013] [Indexed: 12/19/2022]
Abstract
The benzoquinone ansamycin geldanamycin and its derivatives are inhibitors of heat shock protein Hsp90, an emerging target for novel therapeutic agents both in cancer and in neurodegeneration. However, the toxicity of these compounds to normal cells has been ascribed to reaction with thiol nucleophiles at the quinone 19-position. We reasoned that blocking this position would ameliorate toxicity, and that it might also enforce a favourable conformational switch of the trans-amide group into the cis-form required for protein binding. Here, we report an efficient synthesis of such 19-substituted compounds and realization of our hypotheses. Protein crystallography established that the new compounds bind to Hsp90 with, as expected, a cis-amide conformation. Studies on Hsp90 inhibition in cells demonstrated the molecular signature of Hsp90 inhibitors: decreases in client proteins with compensatory increases in other heat shock proteins in both human breast cancer and dopaminergic neural cells, demonstrating their potential for use in the therapy of cancer or neurodegenerative diseases.

Abstract
The 3-O-demethylswertipunicoside (3-ODS) is extracted from Swertia punicea. Recent study from our laboratory has demonstrated that the 3-ODS protects against oxidative toxicity and apoptosis in PC12 cells (Zhang, S.P., Du, X.G., Pu, X.P., 2010. Biol. Pharm. Bull. 33, 1529-1533). The aim of our study is to further investigate the neuroprotective mechanisms of 3-ODS in 1-methyl-4-phenylpyridinium (MPP(+))-induced neurotoxicity in PC12 cells. The results indicated that pre-treatment with 3-ODS significantly increased the cell viability compared with MPP(+) treatment. It also alleviated the oxidative stress by increasing superoxide dismutase (SOD) activity and decreasing malondialdehyde (MDA) level and reactive oxygen specise (ROS) production. Moreover, 3-ODS also attenuated MPP(+)-induced apoptosis by inhibiting Bax and Bcl-2 expressions, activating caspase-9, caspase-3, poly (ADP-ribose) polymerase-1 (PARP-1) cleavage, apoptosis-inducing factor (AIF) translocation and α-synuclein expression. These results suggest that 3-ODS might has applications as a complementary medicine for the treatment of Parkinson's disease (PD) or other neurodegenerative diseases.

Gastrodin protects apoptotic dopaminergic neurons in a toxin-induced Parkinson's disease model. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2013; 2013:514095.

Abstract
Gastrodia elata (GE) Blume is one of the most important traditional plants in Oriental countries and has been used for centuries to improve various conditions. The phenolic glucoside gastrodin is an active constituent of GE. The aim of this study was to investigate the neuroprotective role of gastrodin in 1-methyl-4-phenylpyridinium (MPP+)/1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine- (MPTP) induced human dopaminergic SH-SY5Y cells and mouse model of Parkinson's disease (PD), respectively. Gastrodin significantly and dose dependently protected dopaminergic neurons against neurotoxicity through regulating free radicals, Bax/Bcl-2 mRNA, caspase-3, and cleaved poly(ADP-ribose) polymerase (PARP) in SH-SY5Y cells stressed with MPP+. Gastrodin also showed neuroprotective effects in the subchronic MPTP mouse PD model by ameliorating bradykinesia and motor impairment in the pole and rotarod tests, respectively. Consistent with this finding, gastrodin prevented dopamine depletion and reduced reactive astrogliosis caused by MPTP as assessed by immunohistochemistry and immunoblotting in the substantiae nigrae and striatata of mice. Moreover, gastrodin was also effective in preventing neuronal apoptosis by attenuating antioxidant and antiapoptotic activities in these brain areas. These results strongly suggest that gastrodin has protective effects in experimental PD models and that it may be developed as a clinical candidate to ameliorate PD symptoms.

Abstract
Microglia plays an important role in inflammation-mediated neurodegeneration. Compelling evidence supports the hypothesis that microglial activation contributes to the pathogenesis of various neurodegenerative diseases. However, little is known about the molecular outcome of activated microglia. In this report, we investigate the molecular consequences of MPP(+) toxin-induced activated BV-2 microglia. Intoxication of specific mitochondrial toxin methyl-4-phenylpyridinium iodide ion (MPP(+)) to BV-2 cells induced significant mitochondrial dysfunction and increased the reactive oxygen species generation, caspase-3 activation, and poly ADP ribose polymerase proteolysis. Further, MAC-1 immunostaining in the midbrain of mice revealed a decrease in activated microglia at day 4 after intoxication with MPP(+). From this study, it was confirmed that BV-2 microglia respond to the mitochondrial toxin MPP(+) which may lead to apoptotic cell death. Understanding of the mechanistic basis of apoptotic elimination of activated microglia may help to develop new strategies for the treatment of neurodegenerative diseases.

Abstract
Parkinson's disease (PD) is characterized by the selective loss of dopaminergic (DAergic) neurons in the substantia nigra and the subsequent depletion of dopamine (DA). This study assessed the protective effects of costunolide on DA-induced apoptosis in human DAergic SH-SY5Y cells, and its regulation of DA metabolism-associated gene and protein expression. Annexin V and propidium iodide (PI) staining using flow cytometric analysis (FACS) revealed that costunolide significantly protected human DAergic SH-SY5Y cells against DA-induced apoptosis. In addition, co-treatment of costunolide with DA in SH-SY5Y cells regulated DA metabolism-associated gene expression, as we observed an increase in both mRNA and protein levels of nuclear receptor related-1 (Nurr1), DA transporter (DAT), and vesicular monoamine transporter type 2 (VMAT2). In contrast, α-synuclein (ASYN) protein levels were decreased. Our findings suggest that costunolide has anti-apoptotic activity, presumably due to its regulatory effects on DA metabolism-associated genes. Therefore, costunolide could be considered as a candidate therapy for the treatment of Parkinson's disease.

Abstract
Five new nardosinane-type sesquiterpenoids, paralemnolins Q-U (1-5), along with three known compounds (6-8), were isolated from the Formosan soft coral Paralemnalia thyrsoides. The structures of new metabolites were elucidated on the basis of extensive spectroscopic methods, and the absolute configuration of 1 was determined by the application of Mosher's method on 1. Among these metabolites, 1 and 3 are rarely found nardosinane-type sesquiterpenoids, possessing novel polycyclic structures. Compounds 1, 3, 6 and 7 were found to possess neuroprotective activity.

Abstract
Gastrodia elata Blume (GE) has long been used in oriental countries as a traditional herbal medicine to relieve symptoms associated with neurological ailments such as vertigo, general paralysis and epilepsy. In this study, we have investigated the effects of GE extracts and its major bioactive components on 1-methyl-4-phenylpyridinium (MPP+)-treated MN9D dopaminergic cells, a classic in vitro model for Parkinson’s disease (PD). We found that vanillyl alcohol effectively inhibited the cytotoxicity and improved cell viability in MPP+-induced MN9D dopaminergic cells. The underlying mechanisms of vanillyl alcohol action were also studied. Vanillyl alcohol attenuated the elevation of reactive oxygen species (ROS) levels, decreased in the Bax/Bcl-2 ratio and poly (ADP-ribose) polymerase proteolysis. These results indicate that vanillyl alcohol protected dopaminergic MN9D cells against MPP+-induced apoptosis by relieving oxidative stress and modulating the apoptotic process and is therefore a potential candidate for treatment of neurodegenerative diseases such as Parkinson’s disease.

Abstract
Chrysanthemum indicum Linn. (CI) has been used in Oriental medicine for several centuries. In the present study, the effect of CI extract was evaluated against 1-methyl-4-phenylpridinium ion (MPP(+))-induced damage in SH-SY5Y cells and lipopolysaccharide (LPS)-stimulated BV-2 microglial cells. Cell viability, oxidative damage, reactive oxygen species, expression of Bcl-2/Bax, and poly (ADP-ribose) polymerase (PARP) proteolysis were evaluated using SH-SY5Y cells. Production of iNOS, prostaglandin E(2), and pro-inflammatory cytokines like tumor necrosis factor (TNF)-α, interleukin (IL)-1β, interleukin (IL)-6, expression of cyclooxygenase type-2 (COX-2) and type-1 (COX-1) were examined in activated BV-2 microglia. At 1, 10 and 100 μg, CI inhibited cell loss, decreased the reactive oxygen species production, regulated the Bax/Bcl-2 ratio and inhibited PARP proteolysis in MPP(+)-induced SH-SY5Y cells. Furthermore, CI suppressed the production of prostaglandin E(2,) expression of cyclooxygenase type-2 (COX-2), blocked IκB-α degradation and activation of NF-κB p65 in BV-2 cells in a dose-dependent manner. The molecular mechanisms involved by CI might involve its inhibitory actions both on neuronal apoptosis and neuroinflammatory NF-κB/IκB-α signaling pathway. The present investigation scientifically supports the long history and safe usage of CI as an important functional food with potential benefits in ameliorating deleterious conditions seen in PD.

Abstract
Parkinson's disease (PD) is associated with mitochondrial dysfunction, oxidative stress, and activation of the apoptotic cascade. In the study, we investigated the effects of salvianolic acid B (Sal B) on 1-methyl-4-phenylpyridinium (MPP(+))-treated SH-SY5Y cells, a classic in vitro model for PD. We found Sal B inhibited the loss of cell viability by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The underlying mechanisms of Sal B action were further studied. Treatment of SH-SY5Y cells with MPP(+) caused a loss of cell viability and mitochondrial membrane potential, condensation of nuclei, elevation in the level of reactive oxygen species (which was associated with cytochrome c release), an increase in the Bax/Bcl-2 mRNA ratio, and activation of caspase-3. Sal B ameliorated the MPP(+)-altered phenotypes. These results indicate that the Sal B protected SH-SY5Y cells against MPP(+)-induced apoptosis by relieving oxidative stress and modulating the apoptotic process. Our findings suggest that salvianolic acid B may be a promising agent to prevent PD.

Our continuing effort of searching bioactive substances from the Formosan soft coral Cladiella australis has led to the isolation of a bioactive substance austrasulfone (1), which possesses significant neuroprotective activities. A straightforward synthesis of 1 was achieved by a two-step reaction sequence. Dihydroaustrasulfone alcohol (3), the synthetic precursor of 1, not only exhibited in vitro anti-inflammatory activity, but also showed potent therapeutic ability in the treatment of neuropathic pain, atherosclerosis, and multiple sclerosis in rats.

Abstract
A new series of novel 4-(1H-benz[d]imidazol-2yl)-1,3-thiazol-2-amines 5a-d and 4-(1H-benz[d]imidazol-2yl)-3-alkyl-2,3-dihydro-1,3-thiazol-2-amine 8a-d has been synthesized by the cyclocondensation of 2-acetyl benzimidiazoles 4a-d and 2-bromo-1-(1-alkyl-1H-benzo[d]imidazol-2-yl)-1-ethanone 7a-d with thiourea respectively, and evaluated for their antibacterial and antifungal activity against clinical isolates of Gram-positive and Gram-negative bacteria. Some of these hybrids in these series exhibited antibacterial activity comparable to standard Streptomycin and Benzyl penicillin and antifungal activity against Fluconazole. All the newly synthesized compounds were characterized by their spectral data and further used to estimate their ability towards antimicrobial activity.

Abstract
Parkinson's disease (PD) is an age-related neurodegenerative disorder in whose brain massive loss of dopaminergic neurons and formation of Lewy bodies occur in the substantia nigra (SN). L-Dihydroxyphenylamine (L-DOPA) substitution is still considered the gold standard of antiparkinsonian drug therapy. However, there has been little information available on neuroprotective and regenerative therapies. Recently, we have found that pramipexole and talipexole (D(2)/D(3)-dopaminergic agonists) inhibit dopaminergic neurotoxin-induced production of reactive oxygen species and apoptotic cell death. In addition, treatment with these drugs induces enhancement of anti-apoptotic Bcl-2 expression and inhibition of α-synuclein aggregation. Interestingly, recent study suggests that pramipexole treatment delays the progression of early PD symptom. On the other hand, we investigated the transplantation strategy for PD by assessing whether double-transplants of mouse embryonic stem (ES) cell-derived neurons in the striatum (ST) and SN, or subthalamic nucleus (STN), induce functional recovery in rat hemi-parkinsonian model. The study indicates that both the involvement of ST as a place of transplantation and the number of ES cell-derived neurons are essential factors for efficacy on PD animal model. Interestingly, an invertebrate planarian can regenerate complete organs, including a well-organized central nervous system (brain), within about 7 days. The regeneration process of the planarian dopaminergic neural network (tiara) may be divided into five steps: 1) anterior blastema formation, 2) brain rudiment formation, 3) brain pattern formation, 4) the formation of dopaminergic tiara, and 5) functional recovery of dopaminergic motor regulation, with several kinds of genes and molecular cascades acting at each step.

JOURNAL OF ETHNOPHARMACOLOGY 2010; 130:290-298. [PMID: 20470875 DOI: 10.1016/j.jep.2010.05.006] [Citation(s) in RCA: 54] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/24/2010] [Revised: 04/26/2010] [Accepted: 05/05/2010] [Indexed: 05/29/2023]
Abstract
AIM OF THE STUDY Gastrodia elata (GE) Blume (Orchidaceae) has been traditionally used as a folk medicine in Oriental countries since centuries for their variety of therapeutic benefits. This study is an attempt to investigate the protective effects of GE extract against MPP(+)-induced cytotoxicity in human dopaminergic SH-SY5Y cells and explore the neuroprotective mechanisms involved. MATERIALS AND METHODS Human dopaminergic SH-SY5Y cells were used to demonstrate the protective effects of GE against multiple parameters such as MPP(+)-induced cell viability, oxidative damage, expression of Bcl-2 and Bax, caspase-3 and poly(ADP-ribose) polymerase proteolysis. RESULTS GE effectively attenuated the cytotoxicity and improved cell viability in a dose-dependent manner. GE was effective in inhibiting both, the increased production of reactive oxygen species (ROS) and increase in Bax/Bcl-2 ratio, cleaved caspase-3 and PARP proteolysis. CONCLUSION Data from this study suggests the protective effects of GE on MPP(+)-induced cytotoxicity in dopaminergic cells, which may be ascribed to its significant anti-oxidative and anti-apoptotic properties, thus, GE might prove to be a valuable therapeutic agent for the treatment of various neurodegenerative diseases including progressive Parkinson's disease (PD).
