Effect of Sinapic Acid on Scopolamine-Induced Learning and Memory Impairment in SD Rats. Brain Sci 2023; 13:brainsci13030427. [PMID: 36979237 PMCID: PMC10046676 DOI: 10.3390/brainsci13030427] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2022] [Revised: 01/09/2023] [Accepted: 01/10/2023] [Indexed: 03/06/2023] Open
Abstract
The seriousness of the diseases caused by aging have recently gained attention. Alzheimer’s disease (AD), a chronic neurodegenerative disease, accounts for 60–80% of senile dementia cases. Continuous research is being conducted on the cause of Alzheimer’s disease, and it is believed to include complex factors, such as genetic factors, the accumulation of amyloid beta plaques, a tangle of tau protein, oxidative stress, cholinergic dysfunction, neuroinflammation, and cell death. Sinapic acid is a hydroxycinnamic acid found in plant families, such as oranges, grapefruit, cranberry, mustard seeds, and rapeseeds. It exhibits various biological activities, including anti-inflammatory, anti-oxidant, anti-cancer, and anti-depressant effects. Sinapic acid is an acetylcholine esterase inhibitor that can be applied to the treatment of dementia caused by Alzheimer’s disease and Parkinson’s disease. However, electrophysiological studies on the effects of sinapic acid on memory and learning must still be conducted. Therefore, it was confirmed that sinapic acid was effective in long-term potentiation (LTP) using organotypic hippocampal segment tissue. In addition, the effect on scopolamine-induced learning and memory impairment was measured by oral administration of sinapic acid 10 mg/kg/day for 14 days, and behavioral experiments related to short-term and long-term spatial memory and avoidance memory were conducted. Sinapic acid increased the activity of the field excitatory postsynaptic potential (fEPSP) in a dose-dependent manner after TBS, and restored fEPSP activity in the CA1 region suppressed by scopolamine. The scopolamine-induced learning and memory impairment group showed lower results than the control group in the Y-maze, Passive avoidance (PA), and Morris water maze (MWM) experiments. Sinapic acid improved avoidance memory, short and long-term spatial recognition learning, and memory. In addition, sinapic acid weakened the inhibition of the brain-derived neurotrophic factor (BDNF), tropomyosin receptor kinase B (TrkB) and the activation of prostaglandin-endoperoxide synthase 2 (COX-2) and interleukin 1 beta (IL-1β) induced by scopolamine in the hippocampus. These results show that sinapic acid is effective in restoring LTP and cognitive impairment induced by the cholinergic receptor blockade. Moreover, it showed the effect of alleviating the reduction in scopolamine-induced BDNF and TrkB, and alleviated neuroinflammatory effects by inhibiting the increase in COX-2 and IL-1β. Therefore, we showed that sinapic acid has potential as a treatment for neurodegenerative cognitive impairment.

Effect of chlorogenic acid plus donepezil on critical neurocortical enzyme activities, inflammatory markers, and synaptophysin immunoreactivity in scopolamine-assaulted rats, supported by multiple ligand simultaneous docking. J Food Biochem 2022; 46:e14312. [PMID: 35791518 DOI: 10.1111/jfbc.14312] [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: 03/30/2022] [Revised: 05/23/2022] [Accepted: 06/03/2022] [Indexed: 12/29/2022]
Abstract
The effect of chlorogenic acid (a natural phenolic acid ubiquitous in plant foods) on selected therapeutic properties of donepezil (DON) in a scopolamine (SCOP)-induced rat model of amnesia was the focus of this study. Adult albino (Wister strain) rats were allocated into five groups (n = 11) consisting of control, SCOP, SCOP + chlorogenic acid (CGA), SCOP + DON, and SCOP + CGA + DON for 7 days. Post-treatment, the rat brain cerebral cortex homogenate was assayed for cholinesterase and monoamine oxidase activities. Also, the reactive oxygen species, total thiol and nitric oxide contents, alongside catalase, and superoxide dismutase activities were determined. Routine histology for neuronal and glial cells as well as synaptophysin immunoreactivity was also carried out on the cerebral cortex. Thereafter, multiple ligand simultaneous docking was carried out for DON and CGA at the active sites of AChE and BChE. The results revealed that the biochemical parameters, glial cells, and synaptophysin immunoreactivity were significantly impaired in the cerebral cortex of scopolamine-treated rats. However, impaired butyrylcholinesterase and monoamine oxidase activity, together with antioxidant, glial cells, and synaptophysin levels were significantly ameliorated in scopolamine-treated rats administered DON + CGA compared to donepezil alone. The docking of both DON and CGA at the active sites of AChE or BChE showed higher binding energy to both enzymes compared to individual interactions of either DON or CGA. Hence, this study has been able to show that CGA could improve some of the therapeutic effects of DON, which could broaden the therapeutic spectrum of this drug. PRACTICAL APPLICATIONS: This study showed that chlorogenic acid (a major phenolic acid found in plant foods such as coffee) modulated some of the therapeutic properties of donepezil (an anticholinesterase drug used in the treatment of mild-to-moderate Alzheimer's disease). The combinations elicited better anti-butyrylcholinesterase, antimonoamine oxidase, and antioxidant properties, thus presenting this food-drug interaction as potentially able to offer better therapeutic properties.

Metab Brain Dis 2022; 38:1067-1077.

Abstract
Aging is widely thought to be associated with oxidative stress. Momordica charantia (MC) is a classic vegetable and traditional herbal medicine widely consumed in Asia, and M. charantia polysaccharide (MCP) is the main bioactive ingredient of MC. We previously reported an antioxidative and neuroprotective effect of MCP in models of cerebral ischemia/reperfusion and hemorrhage injury. However, the role played by MCP in neurodegenerative diseases, especially during aging, remains unknown. In this study, we investigated the protective effect of MCP against oxidative stress and brain damage in a D-galactose-induced aging model (DGAM). The Morris water maze test was performed to evaluate the spatial memory function of model rats. The levels of malondialdehyde (MDA), glutathione (GSH), and superoxide dismutase (SOD) were measured and telomerase activity was determined. The results showed that MCP treatment attenuated spatial memory dysfunction induced by D-galactose. In addition, MCP increased antioxidant capacity by decreasing MDA and increasing SOD and GSH levels. MCP treatment also improved telomerase activity in aging rats. Mechanistically, MCP promoted the entry of both Nrf2 and β-Catenin into the nucleus, which is the hallmark of antioxidation signaling pathway activation. This study highlights a role played by MCP in ameliorating aging-induced oxidative stress injury and reversing the decline in learning and memory capacity. Our work provides evidence that MCP administration might be a potential antiaging strategy.

Abstract
BACKGROUND Mercuric chloride (HgCl2) severely impairs the central nervous system when humans are exposed to it. AIMS We investigated the neuroprotective efficiency of Ziziphus spina-christi leaf extract (ZSCLE) on HgCl2-mediated cortical deficits. METHODS Twenty-eight rats were distributed equally into four groups: the control, ZSCLE-treated (300 mg/kg), HgCl2-treated (0.4 mg/kg), and ZSCLE+HgCl2-treated groups. Animals received their treatments for 28 days. RESULTS Supplementation with ZSCLE after HgCl2 exposure prevented the deposition of mercury in the cortical slices. It also lowered malondialdehyde levels and nitrite and nitrate formation, elevated glutathione levels, activated its associated-antioxidant enzymes, glutathione reductase, and glutathione peroxidase, and upregulated the transcription of catalase and superoxide dismutase and their activities were accordingly increased. Moreover, ZSCLE activated the expression of nuclear factor erythroid 2-related factor 2 and heme oxygenase-1 when compared with the HgCl2 group. Notably, post-treatment with ZSCLE increased the activity of acetylcholinesterase and ameliorated the histopathological changes associated with HgCl2 exposure. Furthermore, ZSCLE blocked cortical inflammation, as observed by the lowered mRNA expression and protein levels of interleukin-1 beta and tumor necrosis factor-alpha, as well as decreased mRNA expression of inducible nitric oxide synthase. In addition, ZSCLE decreased neuron loss by preventing apoptosis in the cortical tissue upon HgCl2 intoxication. CONCLUSION Based on the obtained findings, we suggest that ZSCLE supplementation could be applied as a neuroprotective agent to decrease neuron damage following HgCl2 toxicity.

Abstract
Excess glutamate in the central nervous system may be a major cause of neurodegenerative diseases with gradual loss and dysfunction of neurons. Primary or secondary metabolites from medicinal plants and algae show potential for treatment of glutamate-induced excitotoxicity. Three plant extracts were evaluated for impact on glutamate excitotoxicity-induced in primary cultures of retinal ganglion cells (RGC). These cells were treated separately in seven groups: control; Plicosepalus. curviflorus treated; Saussurea lappa treated; Cladophora glomerate treated. Cells were treated independently with 5, 10, 50, or 100 µg/ml of extracts of plant or alga material, respectively, for 2 h. Glutamate-treated cells (48 h with 5, 10, 50, or 100 µM glutamate); and P. curviflorus/glutamate; S. lappa/glutamate; C. glomerata/glutamate [pretreatment with extract for 2 h (50 and 100 µg/ml) before glutamate treatment with 100 µM for 48 h]. Comet and MTT assays were used to assess cell damage and cell viability. The number of viable cells fell significantly after glutamate exposure. Exposure to plant extracts caused no notable effect of viability. All tested plants extracts showed a protective effect against glutamate excitotoxicity-induced RGC death. Use of these extracts for neurological conditions related to excitotoxicity and oxidative stress might prove beneficial.

Abstract
We examined the neuropharmacological effects of ethanol extract of Ficus erecta Thunb leaves (EEFE) on cognitive dysfunction in a scopolamine (SCO)-induced memory impairment animal model. Memory impairment was measured using the Y-maze test and passive avoidance task (PAT). For 19 days, EEFE (100 or 200 mg/kg) was treated through oral administration. Treatment with EEFE ameliorated memory impairment in behavioral tests, along with significant protection from neuronal oxidative stress and neuronal cell loss in the brain tissues of SCO-injected mice. Antioxidant and neuroprotective effects of EEFE were further confirmed using in vitro assays. Our findings indicate that the mechanisms of neuroprotection and antioxidation of EEFE are regulated by the cholinergic system, promotion of cAMP response element-binding protein (CREB) phosphorylation, and the nuclear factor erythroid-2-related factor 2 (Nrf2)/heme oxygenase (HO)-1 signaling activation. The current study proposes that EEFE could be an encouraging plant resource and serve as a potent neuropharmacological drug candidate against neurodegenerative diseases.

Abstract
Neuroinflammation is a key process in the pathogenesis of many neurological disorders, i.e. Alzheimer's disease and Parkinson's disease. However, there are no anti-inflammatory medical interventions recommended so far in the treatment of neuroinflammation-related brain disorders. Therefore, the burden of searching for effective and safe antineuroinflammatory agents is well founded, especially in the aging society. Compounds of plant origin, mainly (poly)phenols, have attracted considerable attention in recent years. Notably, the role of flavonoids in ameliorating neuroinflammation is in the limelight. Thus, we used comprehensive literature retrieval to summarize the effects and active components of edible fruits and their phenolic compounds. As a result, this review presents a valuable summary of results of in vitro, ex vivo, and in vivo studies on the antineuroinflammatory effects of edible fruits and their (poly)phenolic extracts as well as dietary flavonoids and other selected (poly)phenols based on the detailed description of foregoing studies. Additionally, problems resulting from the limited bioavailability of (poly)phenols were discussed.

Abstract
Arsenic is a toxic metalloid abundantly found in nature and used in many industries. Consumption of contaminated water mainly results in human exposure to arsenic. Toxicity (arsenicosis) resulting from arsenic exposure causes cerebral neurodegeneration. Protocatechuic acid (PCA), a phenol derived from edible plants, has antioxidant properties. The present study investigated the neuroprotective potential of PCA against arsenic-induced neurotoxicity in mice. Male Swiss albino mice were divided into four groups: (i) orally administered physiological saline, (ii) orally administered 100 mg/kg PCA, (iii) orally administered 5 mg/kg NaAsO2, and (iv) orally administered 100 mg/kg PCA 120 min prior to oral administration of 5 mg/kg NaAsO2. Each group received its respective treatment for 1 week, after which cortical tissues from each group were analyzed for various parameters of oxidative stress, proinflammatory cytokines, apoptosis-related proteins, and changes in histopathology. NaAsO2-treatment resulted in a significant increase in lipid peroxidation (LPO), inducible nitric oxide synthetase (iNOs), and NO levels, with a decrease in the levels of both enzymatic (superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase) and non-enzymatic (glutathione) antioxidant markers. Arsenic increased proinflammatory cytokine (tumor necrosis factor-α and interleukin-1β) levels, enhanced caspase-3 and Bax expression, and reduced Bcl-2 expression. Furthermore, arsenic-exposure in mice decreased significantly acetylcholinesterase activity and brain-derived neurotrophic factor level in the cerebral cortex. Histopathological examination revealed changes in nerve cell cyto-architecture and distribution in arsenic-exposed brain tissue sections. PCA treatment before arsenic administration resulted in a positive shift in the oxidative stress and cytokine levels with decreased levels of LPO, iNOS, and NO. PCA pre-treatment considerably attenuated arsenic-associated histopathological changes in murine brain tissue. This study suggested that the presence of PCA may be responsible for the prevention of arsenic-induced neurotoxicity.

Abstract
The ever-increasing human population with attendant industrialization poses serious global health challenge. Cadmium (Cd) with other heavy metals contribute greatly to environmental pollutions and humans are daily exposed to them, leading to diverse ailments. We explored whether Hesperidin (HSP) could protect against hepatic damage and dyslipidemia in Wistar rats exposed to Cd. Forty wistar rats were randomly assigned into five groups (n = 8). Group 1 received 2 mL/kg body weight of normal saline; Group 2 received 100 mg/kg body weight of HSP while Group 3 received 5 mg/kg body weight of Cadmium Chloride (CdCl2) for 28 days. Group 4 received 100 mg/kg body weight of HSP and after 90 min, CdCl2 (5 mg/kg) body weight was administered for 28 days. Group 5 received 50 mg/kg body weight of HSP and after 90 min, CdCl2 (5 mg/kg) body weight was administered for 28 days. The serum lipid profiles, hepatic dysfunction and oxidative stress markers were determined using standard methods. Cd toxicity in rats prominently elevated serum activities of AST, ALT, ALP and levels of total bilirubin, direct bilirubin, cholesterol, LDL-C and malondialdehyde with decreased levels of HDL-C, triglycerides, superoxide dismutase, catalase, glutathione and body weights. The pre-treatment of HSP before Cd intoxication prevented the dysregulated activities of liver enzymes and levels of lipid profiles, enzymatic and non-enzymatic antioxidants and other biomarkers investigated, thus suggesting anti-hyperlipidemic and hepato-protective potentials. HSP may have great potentials for development of therapeutics that could enhance the management of dyslipidemia and liver disorders associated with heavy metal exposure.

Saussurea lappa root extract ameliorates the hazards effect of thorium induced oxidative stress and neuroendocrine alterations in adult male rats. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2020; 27:13237-13246. [PMID: 32016872 DOI: 10.1007/s11356-020-07917-y] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/28/2019] [Accepted: 01/28/2020] [Indexed: 06/10/2023]
Abstract
The present study was aimed to estimating the effect of Saussurea lappa (costus) root extract on thorium accumulation in different brain regions (cerebral cortex, cerebellum, and hypothalamus) of adult male albino rats and also to evaluate the antioxidant effect and thyroid gland modulation activity of costus following thorium toxicity. Adult male rats were randomly allocated into four groups; control group receiving saline (0.9% NaCl), thorium group receiving an intraperitoneal (i.p.) injection of thorium nitrate (Th; 6.3 mg/kg bwt), costus group receiving an oral administration of costus extract at 200 mg/kg bwt and costus + thorium group receiving costus 1 h before thorium injection. Thorium injection in rats for 28 days resulted in the accumulation of Th maximally in the cerebellum followed by the cerebral cortex and then in the hypothalamus. The accumulation of Th was associated with significant disturbance in sodium and potassium ions. A significant decrease in monoamines was also observed in different brain regions. Furthermore, the results indicated that Th-induced oxidative stress evidenced by increased lipid peroxidation and nitric oxide and decrease the glutathione content. Additionally, Th caused a significant increase in thyroid-stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4) levels in the serum of rats. However, the pre-administration of costus alleviated all of those disturbances. Our results revealed that costus extract exerted its protective effect mainly through potentiating the antioxidant defense system.

Abstract
Myristica fragrans, commonly known as nutmeg, belongs to the Myristicaceae family and is used as a spice and for its medicinal properties. The purpose of this study was to assess the neuroprotective effect of M. fragrans seed methanolic extract (MFE) on scopolamine-induced oxidative damage, inflammation, and apoptosis in male rat cortical tissue. MFE or N-acetylcysteine (NAC), a standard antioxidant drug, was administered 7 days before treatment with scopolamine resulted in high levels of malondialdehyde and nitric oxide (oxidative stress biomarkers), tumor necrosis factor-alpha and interleukin-1 beta (inflammatory mediators), and Bax and caspase-3 pro-apoptotic proteins. Additionally, scopolamine significantly depleted levels of glutathione (an antioxidant marker), Bcl-2 and c-FLIP (anti-apoptotic proteins), and antioxidant enzymes activity in cortical tissue. Scopolamine also enhanced acetylcholinesterase activity. MFE treatment protected the cortex of rats from the effects of scopolamine by reversing the effects on these toxicity markers. Interestingly, the neuroprotective effect of MFE was comparable to that exerted by the reference antioxidant NAC. Thus, our findings show that MFE has antioxidant, anti-inflammatory, and anti-apoptotic effects. The beneficial effects of MFE on scopolamine were partially mediated by promoting heme oxygenase 1 (Hmox1) expression and preserving cortical tissue structure.

Senna alexandrina extract supplementation reverses hepatic oxidative, inflammatory, and apoptotic effects of cadmium chloride administration in rats.

Abstract
Senna alexandrina is traditionally used for its antioxidant and anti-inflammatory properties, but little information is available concerning its potential protective effects against cadmium, which is a widespread environmental toxicant that causes hepatotoxicity. Here, we explored the effects of S. alexandrina extract (SAE) on cadmium chloride (CdCl2)-induced liver toxicity over 4 weeks in rats. Rats were allocated into four groups: control, SAE (100 mg/kg), CdCl2 (0.6 mg/kg), and SAE + CdCl2, respectively. Cadmium level in hepatic tissue, blood transaminases, and total bilirubin as indicators of liver function were assessed. Oxidative stress indices [malondialdehyde (MDA), nitrate/nitrite (NO), and glutathione (GSH)], antioxidant molecules [superoxide dismutase (SOD, catalase (CAT), glutathione-derived enzymes, and nuclear factor erythroid 2-related factor 2 (Nrf2)], pro-inflammatory mediators [interleukin-1 beta (IL-1β) and tumor necrosis factor-alpha (TNF-α)], apoptosis proteins (Bcl-2, Bax, and caspase-3), and histological alterations to the liver were examined. SAE administration before CdCl2 exposure decreased cadmium deposition in liver tissue and the blood liver function indicators. SAE pre-treatment prevented oxidative, inflammatory, and apoptotic reactions and decreased histological alterations to the liver caused by CdCl2 exposure. SAE can be used as a promising protective agent against CdCl2-induced hepatotoxicity by increasing Nrf2 expression. Graphical abstract.

Antagonistic Efficacy of Luteolin against Lead Acetate Exposure-Associated with Hepatotoxicity is Mediated via Antioxidant, Anti-Inflammatory, and Anti-Apoptotic Activities. Antioxidants (Basel) 2019; 9:antiox9010010. [PMID: 31877779 PMCID: PMC7022878 DOI: 10.3390/antiox9010010] [Citation(s) in RCA: 54] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2019] [Revised: 12/13/2019] [Accepted: 12/16/2019] [Indexed: 01/24/2023] Open
Abstract
The abundant use of lead (Pb; toxic heavy metal) worldwide has increased occupational and ecosystem exposure, with subsequent negative health effects. The flavonoid luteolin (LUT) found in many natural foodstuffs possesses antioxidant and anti-inflammatory properties. Herein, we hypothesized that LUT could mitigate liver damage induced by exposure to lead acetate (PbAc). Male Wistar rats were allocated to four groups: control group received normal saline, LUT-treated group (50 mg/kg, oral, daily), PbAc-treated group (20 mg/kg, i.p., daily), and LUT+PbAc-treated group (received the aforementioned doses via the respective routes of administration); the rats were treated for 7 days. The results revealed that PbAc exposure significantly increased hepatic Pb residue and serum activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), and total bilirubin value. Oxidative reactions were observed in the liver tissue following PbAc intoxication, characterized by the depletion and downregulation of antioxidant proteins (glutathione, glutathione reductase, glutathione peroxidase, superoxide dismutase, catalase, nuclear factor erythroid 2-related factor 2, and heme oxygenase-1), and an increase in oxidants (malondialdehyde and nitric oxide). Additionally, PbAc increased the release and expression of the pro-inflammatory cytokines (tumor necrosis factor alpha and interleukin-1 beta), inducible nitric oxide synthase, and nuclear factor kappa B. Moreover, PbAc enhanced hepatocyte loss by increasing the expression of pro-apoptotic proteins (Bax and caspase-3) and downregulating the anti-apoptotic protein (Bcl-2). The changes in the aforementioned parameters were further confirmed by noticeable histopathological lesions. LUT supplementation significantly reversed all of the tested parameters in comparison with the PbAc-exposed group. In conclusion, our findings describe the potential mechanisms involved in the alleviation of PbAc-induced liver injury by luteolin via its potent anti-inflammatory, antioxidant, and anti-apoptotic properties.

Abstract
Chlorpyrifos (CPF) is a widely used organophosphate insecticide with several harmful effects. N-acetylcysteine (NAC) represents an ideal antixenobiotic; it can directly enter endogenous biochemical processes and is used as adjunctive treatment for psychiatric disorders. We aimed to evaluate the neuroprotective effect of NAC as an antioxidant drug against CPF-induced neurotoxicity in adult male albino rat brains. Twenty-eight male Wister rats were allocated into four groups (n = 7) and were administered the following for 28 days: group I (control group), physiological saline (0.9% NaCl); group II (CPF group), 10 mg/kg body weight (BW) CPF; group III (NAC group), 100 mg/kg BW NAC; and group VI (CPF+NAC group), NAC 1 h before CPF. CPF intoxication resulted in acetylcholinesterase inhibition, reduced glutathione content, and elevated levels of malondialdehyde and nitric oxide, which are oxidative stress biomarkers. CPF also depleted the activity of antioxidant enzymes, superoxide dismutase and catalase, and levels of inflammatory mediators, tumor necrosis factor-α, interleukin (IL)-6, and IL-1β. Levels of vascular endothelial growth factor, Bax, and the proapoptotic caspases-3 also increased, while brain-derived neurotrophic factor level decreased. Additionally, CPF significantly diminished Bcl-2 (an antiapoptotic protein) in rat brain cortical tissue. NAC treatment was found to protect brain tissue by reversing the CPF-induced neurotoxicity. Our results show the antioxidant, antiinflammatory, and antiapoptotic effects of NAC on CPF-induced neurotoxicity in rat brain tissue.
