Abstract
BACKGROUND Alzheimer's disease (AD), the most common form of progressive dementia in the elderly, is a chronic neurological disorder that decreases cognitive ability. Although the underlying cause of AD is yet unknown, oxidative stress and brain acetylcholine shortage are the key pathogenic causes. RESULTS The current study shows that these derivatives have the potential to improve memory in mice by inhibiting scopolamine-induced acetylcholinesterase activity, oxidative and nitrosative stress, and improving locomotor activity and muscle grip strength in the rota rod test. When compared to the illness control, the memory-enhancing potential of novel N-benzyl pyridine-2-one derivatives was highly significant (P < 0.0001). CONCLUSIONS The observed memory ameliorating effect of novel N-benzyl pyridine-2-one makes them as a a good choice for treatment of individuals with cognitive impairment.

Abstract
Alzheimer's disease (AD) is a long-term neurodegenerative condition that impairs cognitive abilities. Brain acetylcholine deficit and oxidative stress may be considered the key pathogenic causes for AD, even though the basic etiology is still unknown. The effects of some novel pyrrolidine-2-one derivatives on the learning and memory deficits caused by scopolamine in mice were examined in the current study. The learning and memory parameters were assessed using the morris water maze test, rota rod test the and locomotor activity. A number of biochemical factors were also evaluated, including acetylcholinesterase (AChE), lipid peroxidation (LPO), reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CA), and nitrite oxide (NO) assay. The current study shows that these derivatives were more effective and comparable to donepezil at treating the behavioral and biochemical changes brought on by scopolamine. The observed results showed pyrrolidine-2-one derivatives as a promising candidate for diseases associated with cognitive deficits.

Abstract
Natural products can generally exhibit a variety of biological activities, but most show mediocre performance in preliminary activity evaluation. Natural products often require structural modification to obtain promising lead compounds. Cinnamic acid (CA) is readily available and has diverse biological activities and low cytotoxicity. Introducing CA into natural products may improve their performance, enhance biological activity, and reduce toxic side effect. Herein, we aimed to discuss related applications of CA in the structural modification of natural products and provide a theoretical basis for future derivatization and drug development of natural products. Published articles, web databases (PubMed, Science Direct, SCI Finder, and CNKI), and clinical trial websites (https://clinicaltrials.gov/) related to natural products and CA derivatives were included in the discussion. Based on the inclusion criteria, 128 studies were selected and discussed herein. Screening natural products of CA derivatives allowed for classification by their biological activities. The full text is organized according to the biological activities of the derivatives, with the following categories: anti-tumor, neuroprotective, anti-diabetic, anti-microbial, anti-parasitic, anti-oxidative, anti-inflammatory, and other activities. The biological activity of each CA derivative is discussed in detail. Notably, most derivatives exhibited enhanced biological activity and reduced cytotoxicity compared with the lead compound. CA has various advantages and can be widely used in the synthesis of natural product derivatives to enhance the properties of drug candidates or lead compounds.

Abstract
Numerous challenges are confronted when it comes to the recognition of therapeutic agents for treating complex neurodegenerative diseases like Alzheimer's disease (AD). The perplexing pathogenicity of AD embodies cholinergic dysfunction, amyloid beta (Aβ) aggregation, neurofibrillary tangle formation, neuroinflammation, mitochondrial disruption along with vicious production of reactive oxygen species (ROS) generating oxidative stress. In this frame of reference, drugs with multi target components could prove more advantageous to counter complex pathological mechanisms that are responsible for AD progression. For as much as, medicinal plant based pharmaco-therapies are emerging as potential candidates for AD treatment keeping the efficacy and safety parameters in terms of toxicity and side effects into consideration. Huperzine A (Hup A) is a purified alkaloid compound extracted from a club moss called Huperzia serrata. Several studies have reported both cholinergic and non-cholinergic effects of this compound on AD with significant neuroprotective properties. The present review convenes cumulative demonstrations of neuroprotection provided by Hup A in in vitro, in vivo, and human studies in various pathologies. The underlying molecular mechanisms of its actions have also been discussed. However, more profound evidence would certainly promote the therapeutic implementation of this drug thus furnishing decisive insights into AD therapeutics and various other pathologies along with preventive and curative management.

Abstract
Alzheimer’s disease (AD) is a progressive neuronal/cognitional dysfunction, leading to disability and death. Despite advances in revealing the pathophysiological mechanisms behind AD, no effective treatment has yet been provided. It urges the need for finding novel multi-target agents in combating the complex dysregulated mechanisms in AD. Amongst the dysregulated pathophysiological pathways in AD, oxidative stress seems to play a critical role in the pathogenesis progression of AD, with a dominant role of nuclear factor erythroid 2-related factor 2 (Nrf2)/Kelch-like ECH-associated protein-1 (Keap1)/antioxidant responsive elements (ARE) pathway. In the present study, a comprehensive review was conducted using the existing electronic databases, including PubMed, Medline, Web of Science, and Scopus, as well as related articles in the field. Nrf2/Keap1/ARE has shown to be the upstream orchestrate of oxidative pathways, which also ameliorates various inflammatory and apoptotic pathways. So, developing multi-target agents with higher efficacy and lower side effects could pave the road in the prevention/management of AD. The plant kingdom is now a great source of natural secondary metabolites in targeting Nrf2/Keap1/ARE. Among natural entities, phenolic compounds, alkaloids, terpene/terpenoids, carotenoids, sulfur-compounds, as well as some other miscellaneous plant-derived compounds have shown promising future accordingly. Prevailing evidence has shown that activating Nrf2/ARE and downstream antioxidant enzymes, as well as inhibiting Keap1 could play hopeful roles in overcoming AD. The current review highlights the neuroprotective effects of plant secondary metabolites through targeting Nrf2/Keap1/ARE and downstream interconnected mediators in combating AD.

Abstract
We explored the preventative effect of Annona atemoya leaf (AAL) extract on memory impairment in a scopolamine (SCO)-induced cognitive deficit mouse model. Fifty-eight mice were randomly divided into six groups and orally treated with AAL extract at (50, 100, or 200 mg/kg) or tacrine (TAC) for 21 days. Memory deficits were induced by a single injection of 1 mg/kg SCO (i.p.) and memory improvement was evaluated by using behavioral tests such as the passive avoidance task and Y-maze test. The levels of cholinergic functions, neuronal cell death, reactive oxygen species, and protein expression related to hippocampal neurogenesis were examined by immunohistochemical staining and western blotting. The administration of AAL extract improved memory impairment according to increased spontaneous alternation in the Y-maze and step-through latency in passive avoidance test. AAL extract treatment increased the acetylcholine content, choline acetyltransferase, and acetylcholinesterase activity in the hippocampus of SCO-stimulated mice. In addition, AAL extract attenuated oxidative stress-induced neuronal cell death of hippocampal tissue. In terms of the regulatory mechanisms, AAL extract treatment reversed the SCO-induced decreases in the expression of Akt, phosphorylation of cAMP response element binding protein, and brain-derived neurotrophic factor. Our findings demonstrate that AAL extract has the ability to alleviate memory impairment through preventative effect on cholinergic system dysfunction and oxidative stress-related neuronal cell death in a SCO-induced memory deficit animal model. Overall, AAL may be a promising plant resource for the managing memory dysfunction due to neurodegenerative diseases, such as Alzheimer’s disease (AD).

Abstract
The flavonoid compound scutellarin (Scu) is a traditional Chinese medicine used to treat a variety of diseases; however, the use of scutellarein (Scue), the hydrolysate of Scu, and its mechanisms of action in Alzheimer's disease (AD) have not been fully elucidated. In the present study, the effects of Scue on amyloid β (Aβ)-induced AD-like pathology were investigated. An in vitro model of inflammation and an aged rat model were used to confirm the effects of Scue. In vitro MTT assays and flow cytometry were used to assess the effects of Scue on cell viability and apoptosis, respectively. A Morris water maze was used to evaluate spatial learning and memory, and the levels of Aβ deposition, superoxide dismutase, malondialdehyde, apoptosis, neuro-inflammatory factors and nuclear factor-κB (NF-κB) activation in hippocampal tissues in vivo were measured to determine the effect of Scue in AD. Scue may be protective, as it decreased the apoptosis of hippocampal cells in vitro, inhibited Aβ-induced cognitive impairment, suppressed hippocampal neuro-inflammation and suppressed activation of NF-κB in vivo. Therefore, Scue may be a useful agent for the treatment of Aβ-associated pathology in the central nervous system through inhibition of the protein kinase B/NF-κB signaling pathway and thus, future studies are required to investigate the efficacy of Scue in patients with AD.

Abstract
We have investigated the neuroprotective and memory enhancing effect of [6]-gingerol (GIN), a pungent ingredient of ginger, using an animal model of amnesia. To determine the neuroprotective effect of GIN on cognitive dysfunction, scopolamine (SCO, 1 mg/kg, i.p.) was injected into C57BL/6 mice, and a series of behavioral tests were conducted. SCO-induced behavior changes and memory impairments, such as decreased alteration (%) in Y-maze test, increased mean escape latency in water maze test, diminished step-through latency in passive avoidance test, and shortened freezing time in fear condition test, were significantly prevented and restored by the oral administration of GIN (10 or 25 mg/kg/day). To further verify the neuroprotective mechanism of GIN, we have focused on the brain-derived neurotrophic factor (BDNF). The administration of GIN elevated the protein expression of BDNF, which was mediated via the activation of protein kinase B/Akt- and cAMP-response element binding protein (CREB) signaling pathway. These results suggest that GIN may have preventive and/or therapeutic potentials in the management of memory deficit and cognitive impairment in mice with amnesia.

Abstract
Background Ginsenoside Rb1 (Rb1), a dominant component from the extract of Panax ginseng root, exhibits neuroprotective functions in many neurological diseases. This study was intended to investigate whether Rb1 can attenuate cisplatin-induced memory impairments and explore the potential mechanisms. Methods Cisplatin was injected intraperitoneally with a dose of 5 mg/kg/wk, and Rb1 was administered in drinking water at the dose of 2 mg/kg/d to rats for 5 consecutive wk. The novel objects recognition task and Morris water maze were used to detect the memory of rats. Nissl staining was used to examine the neuron numbers in the hippocampus. The activities of superoxide dismutase, glutathione peroxidase, cholineacetyltransferase, acetylcholinesterase, and the levels of malondialdehyde, reactive oxygen species, acetylcholine, tumor necrosis factor-α, interleukin-1β, and interleukin-10 were measured by ELISA to assay the oxidative stress, cholinergic function, and neuroinflammation in the hippocampus. Results Rb1 administration effectively ameliorates the memory impairments caused by cisplatin in both novel objects recognition task and Morris water maze task. Rb1 also attenuates the neuronal loss induced by cisplatin in the different regions (CA1, CA3, and dentate gyrus) of the hippocampus. Meanwhile, Rb1 is able to rescue the cholinergic neuron function, inhibit the oxidative stress and neuroinflammation in cisplatin-induced rat brain. Conclusion Rb1 rescues the cisplatin-induced memory impairment via restoring the neuronal loss by reducing oxidative stress and neuroinflammation and recovering the cholinergic neuron functions.

Metab Brain Dis 2016; 31:1455-1461. [PMID: 27444169 DOI: 10.1007/s11011-016-9877-z] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/14/2016] [Accepted: 07/14/2016] [Indexed: 02/02/2023]
Abstract
Timosaponin B-II (TB-II) is a main active saponin isolated from the rhizome of Anemarrhena asphodeloides Bge., which is widely used in traditional Chinese medicine. In this study, the effect of TB-II on learning and memory was investigated in a scopolamine-induced mouse model of Alzheimer's disease. The results of behavioral tests indicated that TB-II significantly increased the spontaneous alternation in the Y-maze test, and reversed the shortening of step-through latency induced by scopolamine in the passive avoidance test, showing protective effects on short-term and working memory. In the Morris water maze test, TB-II reduced the escape latency time in the training trial, and increased the swimming time in the target quadrant in the probe trial. Biochemical data demonstrated that TB-II significantly inhibited acetylcholinesterase (AChE) activity in the cerebral cortex and hippocampus of mice. Moreover, TB-II markably attenuated the reduction in glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) activities, and decreased malondialdehyde (MDA) levels, which are key biomarkers of brain oxidative stress. These results indicated that TB-II offers protection against scopolamine-induced deficits in learning and memory, possibly by inhibiting AChE and preventing oxidative stress damage. The findings suggested that TB-II has a potential therapeutic effect on cognitive and behavioral impairment.

Abstract
Amyloid-β peptide (Aβ) is known to be directly associated with the progressive neuronal death observed in Alzheimer’s disease (AD). However, effective neuroprotective approaches against Aβ neurotoxicity are still unavailable. In the present study, we investigated the protective effects of Akebia saponin D (ASD), a typical compound isolated from the rhizome of Dipsacus asper Wall, on Aβ1–42-induced impairment of learning and memory formation and explored the probable underlying molecular mechanisms. We found that treatment with ASD (30, 90 or 270 mg/kg) significantly ameliorated impaired spatial learning and memory in intracerebroventricularly (ICV) Aβ1–42-injected rats, as evidenced by a decrease tendency in escape latency during acquisition trials and improvement in exploratory activities in the probe trial in Morris water maze (MWM). Further study showed that ASD reversed Aβ1–42-induced accumulation of Aβ1–42 and Aβ1–40 in the hippocampus through down-regulating the expression of BACE and Presenilin 2 accompanied with increased the expression of TACE, IDE and LRP-1. Taken together, our findings suggested that ASD exerted therapeutic effects on Aβ-induced cognitive deficits via amyloidogenic pathway.

Abstract
BACKGROUND Polygala tenuifolia Willd is a Traditional Chinese Medicine used for the treatment of learning and memory deficits. Triterpenoid saponins, the main bioactive compounds of Polygala tenuifolia Willd, are easily hydrolyzed to polygalacic acid (PA). PURPOSE The present study was undertaken to investigate the neuroprotective effects of PA on scopolamine-induced cognitive dysfunction and to elucidate its underlying mechanisms of action. METHODS PA (3, 6, and 12 mg/kg) was administered orally to mice for fourteen days, and scopolamine (1 mg/kg) was injected intraperitoneally for fourteen days to induce memory impairment. Memory-related behaviors were evaluated using the Morris water maze. Cholinergic and neuroinflammatory activities were measured in brain tissue. Superoxide dismutase activities, malondialdehyde and reduced glutathione contents were also measured in the brains. RESULTS Treatment with scopolamine significantly increased the escape latency time, decreased the number of crossings, and shortened the time spent in the target quadrant, while PA reversed these scopolamine-induced effects. PA significantly improved cholinergic system reactivity, as indicated by decreased acetylcholinesterase (AChE) activity, increased choline acetyltransferase (ChAT) activity, and elevated levels of acetylcholine (ACh) in the hippocampus and frontal cortex. PA also significantly ameliorated neuroinflammation and oxidative stress in mice. CONCLUSION These results suggest that PA might exert a significant neuroprotective effect on cognitive impairment, driven in part by the modulation of cholinergic activity and neuroinflammation.

Abstract
BACKGROUND Studies have shown that Angelica sinensis (JiLin AoDong Medicine Industry Groups Co., Ltd., Jilin, China) root (AS) ameliorates various diseases, although its effects in Alzheimer's disease (AD) have not been elucidated. PURPOSE The present study examined the effects of AS in a rat model of AD. METHODS Positional Aβ injections were administered to rats. The behavioral effects of AS administration were examined using the Morris water maze, and the molecular effects on gene and protein expression, and apoptosis, were determined. RESULTS AS reversed the social behavioral impairments observed in this rat model of Aβ-induced memory impairment. Western blot analysis also revealed lower hippocampal levels of Aβ and β-site amyloid precursor protein-cleaving enzyme. Terminal deoxynucleotidyl transferased UTP nick end labeling indicated that AS significantly inhibited apoptosis via effects on nuclear factor kappa B (NF-κB) signaling. Real-time PCR, enzyme-linked immunosorbent assay, and immunohistochemical staining indicated that AS effectively inhibited inflammation and upregulated expression of glial cell line-derived neurotrophic factor (GDNF) and brain-derived neurotrophic factor (BDNF) in the hippocampus of this rat AD model. DISCUSSION AS effectively rescued the symptoms of AD in a rat model by inhibiting inflammation, apoptosis, and NF-κB signaling pathway. CONCLUSION These findings suggested that AS could provide a potential drug for the treatment of AD.

Antiamnesic and Antioxidants Effects of Ferulago angulata Essential Oil Against Scopolamine-Induced Memory Impairment in Laboratory Rats. Neurochem Res 2015; 40:1799-809.

Abstract
Ferulago angulata (Apiaceae) is a shrub indigenous to western Iran, Turkey and Iraq. In traditional medicine, F. angulata is recommended for treating digestive pains, hemorrhoids, snake bite, ulcers and as sedative. In the present study, the effects of inhaled F. angulata essential oil (1 and 3%, daily, for 21 days) on spatial memory performance were assessed in scopolamine-treated rats. Scopolamine-induced memory impairments were observed, as measured by the Y-maze and radial arm-maze tasks. Decreased activities of superoxide dismutase, glutathione peroxidase and catalase along with increase of acetylcholinesterase activity and decrease of total content of reduced glutathione were observed in the rat hippocampal homogenates of scopolamine-treated animals as compared with control. Production of protein carbonyl and malondialdehyde significantly increased in the rat hippocampal homogenates of scopolamine-treated animals as compared with control, as a consequence of impaired antioxidant enzymes activities. Additionally, in scopolamine-treated rats exposure to F. angulata essential oil significantly improved memory formation and decreased oxidative stress, suggesting memory-enhancing and antioxidant effects. Therefore, our results suggest that multiple exposures to F. angulata essential oil ameliorate scopolamine-induced spatial memory impairment by attenuation of the oxidative stress in the rat hippocampus.

Long-term administration of scopolamine interferes with nerve cell proliferation, differentiation and migration in adult mouse hippocampal dentate gyrus, but it does not induce cell death.

Abstract
Long-term administration of scopolamine, a muscarinic receptor antagonist, can inhibit the survival of newly generated cells, but its effect on the proliferation, differentiation and migration of nerve cells in the adult mouse hippocampal dentate gyrus remain poorly understood. In this study, we used immunohistochemistry and western blot methods to weekly detect the biological behaviors of nerve cells in the hippocampal dentate gyrus of adult mice that received intraperitoneal administration of scopolamine for 4 weeks. Expression of neuronal nuclear antigen (NeuN; a neuronal marker) and Fluoro-Jade B (a marker for the localization of neuronal degeneration) was also detected. After scopolamine treatment, mouse hippocampal neurons did not die, and Ki-67 (a marker for proliferating cells)-immunoreactive cells were reduced in number and reached the lowest level at 4 weeks. Doublecortin (DCX; a marker for newly generated neurons)-immunoreactive cells were gradually shortened in length and reduced in number with time. After scopolamine treatment for 4 weeks, nearly all of the 5-bromo-2'-deoxyuridine (BrdU)-labeled newly generated cells were located in the subgranular zone of the dentate gyrus, but they did not migrate into the granule cell layer. Few mature BrdU/NeuN double-labeled cells were seen in the subgranular zone of the dentate gyrus. These findings suggest that long-term administration of scopolamine interferes with the proliferation, differentiation and migration of nerve cells in the adult mouse hippocampal dentate gyrus, but it does not induce cell death.

Abstract
Bushen‑Yizhi formula (BSYZ), a traditional Chinese medicine formula consisting of six herbs has been reported to possess a neuroprotective effect. The present study aimed to investigate the effects of BSYZ on learning and memory abilities, as well as oxidative stress and neuronal apoptosis in the hippocampus of scopolamine (SCOP)‑induced senescence in mice, in order to reveal whether BSYZ is a potential therapeutic agent for Alzheimer's disease (AD). A high‑performance liquid chromatography (HPLC) fingerprint was applied to provide a chemical profile of BSYZ. Extracts of BSYZ were orally administered to mice with SCOP‑induced memory impairment for two weeks. The learning and memory abilities were determined by the Morris water maze test. The oxidant stress‑related indices, such as activity of superoxide dismutase (SOD) and levels of glutathione (GSH) and malondialdehyde (MDA) were examined in hippocampus of SCOP‑treated mice. The cell death ratio was assessed by TUNEL staining, while apoptotic‑related proteins including Bcl‑2 and Bax were determined by immuno-fluorescent staining and western blot analysis. Caspase‑3 was determined by western blot analysis. Consequently, a chromatographic condition, which was conducted at 35˚C with a flow rate of 0.8 ml/min on the Gemini C18 column with mobile phase of acetonitrile and water‑phosphoric acid (100:0.1, v/v), was established to yield common fingerprint chromatography under 203 nm with a similarity index of 0.986 within 10 batches of BSYZ samples. BSYZ at a dose of 2.92 g/kg significantly improved the cognitive ability, restored the abnormal activity of SOD and increased the levels of MDA and GSH induced by SCOP. Moreover, the neural apoptosis in the hippocampus of SCOP‑treated mice was reversed by BSYZ by regulating the expression of Bcl‑2, Bax and caspase‑3. The results demonstrated that BSYZ had neuroprotective effects in SCOP‑induced senescence in mice by ameliorating oxidative stress and neuronal apoptosis in the brain, supporting its potential in AD treatment.

Ethanol extract of Astragali Radix and Salviae Miltiorrhizae Radix, Myelophil, exerts anti-amnesic effect in a mouse model of scopolamine-induced memory deficits. JOURNAL OF ETHNOPHARMACOLOGY 2014; 153:782-792. [PMID: 24690775 DOI: 10.1016/j.jep.2014.03.048] [Citation(s) in RCA: 36] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/18/2013] [Revised: 11/20/2013] [Accepted: 03/18/2014] [Indexed: 06/03/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Myelophil, a combination of extracts taken from Astragali Radix and Salviae Miltiorrhizae Radix, is a traditional Chinese medicine used for the treatment of chronic fatigue-associated disorders. Here we examined the ability of Myelophil to alleviate memory impairment in a mouse model. We aimed to investigate whether Myelophil has the pharmacological effects on memory deficits associated with brain dysfunctions using an animal model. MATERIALS AND METHODS Ten week-old male C57BL/6N mice were pretreated with Myelophil (50, 100, or 200 mg/kg), or tacrine (10 mg/kg) for 7 days, and then intraperitoneally injected with scopolamine (1 mg/kg). Memory-related behaviors were evaluated using the Morris water maze for 5 days. Levels of biomarkers of oxidative stress, antioxidant activity, acetylcholinesterase (AChE) activity, and extracellular signal-regulated kinase (ERK) were measured in brain tissues. RESULTS Scopolamine treatment increased the escape latency time and shortened time spent in the target quadrant; these effects were ameliorated by pretreatment with Myelophil. Scopolamine-induced changes in reactive oxygen species (ROS), malondialehyde (MDA), and AChE activity were significantly attenuated in mice pretreated with Myelophil. Recovery of antioxidant capacities, including total glutathione (GSH) content, and the activities of GSH-reductase, GSH-S-transferase, and catalase was also evident in Myelophil-treated mice. The strongest effects were seen for ERK and muscarinic acetylcholine receptor 1 (mAChR1) at both the protein and gene expression levels, with significant amelioration of expression levels in the Myelophil pretreatment group. CONCLUSIONS These results suggest that Myelophil confers anti-amnesic properties in a mouse model of memory impairment, driven in part by the modulation of cholinergic activity.

Effects of the hydro-alcoholic extract of Nigella sativa on scopolamine-induced spatial memory impairment in rats and its possible mechanism. Chin J Integr Med 2014; 21:438-44. [PMID: 24584756 DOI: 10.1007/s11655-014-1742-5] [Citation(s) in RCA: 68] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2012] [Indexed: 01/24/2023]
Abstract
OBJECTIVE To evaluate the effect of Nigella sativa (NS) extract on memory performance and its possible mechanisms in scopolamine (Sco)-induced spatial memory impairment model using Morris water maze test. METHODS Thirty-two male Wistar rats were randomly divided into four groups. The control group received saline instead of both NS extract and Sco. The Sco group was treated by saline for two weeks, and was injected by Sco (2 mg/kg, intraperitoneally) 30 min before each trail in Morris water maze test. Sco+NS 200 and Sco+NS 400 groups were daily treated by 200 or 400 mg/kg of NS (intraperitoneally) for two weeks, respectively, and were finally injected by Sco 30 min before Morris water maze test. The brains of animals were removed to determine the acetylcholinesterase (AChE) activity and oxidative stress criteria in cortical tissues. RESULTS Time latency and path length in the Sco group were significantly higher than in the control group (P<0.01), while the Sco+NS 400 group showed a significantly shorter traveled path length and time latency compared with the Sco group (P<0.01). AChE activity in the cortical tissues of the Sco group was significantly higher than the control group (P<0.01), while AChE activity in the Sco+NS 200 and Sco+NS 400 groups was lower than the Sco group (P<0.01). Following Sco administration, malondialdehyde (MDA) concentrations were increased (P<0.01) in comparison with the control group, while cortical total thiol content decreased (P<0.01). Pretreatment with extracts caused a significant elevation in cortical total thiol content (P<0.01) and reduction in cortical MDA concentration (P<0.01) compared with the Sco group. CONCLUSIONS Hydro-alcoholic extract of NS prevents Sco-induced spatial memory deficits and decreases the AChE activity as well as oxidative stress of brain tissues in rats. Our results support the traditional belief about the beneficial effects of NS in nervous system. Moreover, further investigations are needed for better understanding of this protective effect.

Neuroprotective effects of forsythiaside on learning and memory deficits in senescence-accelerated mouse prone (SAMP8) mice. Pharmacol Biochem Behav 2013; 105:134-41.

Abstract
Forsythiaside (3,4-dihydroxy-β-phenethyl-O-α-L-rhamnopyranosyl-(1→6)-4-O-caffeo yl-β-d-glucopyranoside, C29H36O15), which is isolated from air-dried fruits of Forsythia suspensa, has been shown to possess anti-oxidant, anti-bacterial and anti-inflammatory activities. The aim of this study is to investigate the neuroprotective effects of forsythiaside on learning and memory deficits in the senescence-accelerated mouse prone 8 (SAMP8, a model of age-dependent neurodegenerative disorders such as Alzheimer's disease). Forsythiaside (60, 120 and 240mg/kg) was orally administered to aged (8months old) SAMP8 mice for 45days followed by evaluating cognitive impairment (Morris water maze and step-through passive avoidance), inflammation (interleukin-1β (IL-1β) and interleukin-6 (IL-6) levels), oxidative stress (glutathione peroxidase (GSH-Px) and total superoxide dismutase (T-SOD) activities; malondialdehyde (MDA) and nitric oxide (NO) contents) and neurotransmitter such as norepinephrine (NE), dopamine (DA), 5-hydroxytryptamine (5-HT), glutamate (GLU) gamma-aminobutyric acid (GABA) and acetyl choline (ACh). In Morris water maze, forsythiaside had significantly reduced the latency time, the crossing numbers and time spent in target quadrant compared to aged SAMP8 mice. In passive avoidance test, a significant decline in number of errors while increase in latency was observed when compared with aged SAMP8 mice. Furthermore, a significant decrease in IL-1β, NO, MDA and NE levels, and an increase in T-SOD and GSH-Px activities and GLU and Ach levels were evident in the brain homogenates of forsythiaside-treated mice compared to aged SAMP8 mice. These findings demonstrated that forsythiaside may be a useful treatment against amnesia.

Abstract
Cholinergic deficit is one of the most remarkable symptoms and plays an important role in Alzheimer's disease. In the present study, the protective effects of Akebia saponin D (ASD) on learning and memory impairments induced by excitatory neurotoxin ibotenic acid injection were examined in vivo. Our findings suggest that ASD (90 mg/kg, p.o.) would exert a rescue effect on rats both in behavioral performances in Morris water maze and Y maze and cholinergic functions detected by chemical methods. We further investigated in the hippocampus and found ASD could regulate apoptosis-related proteins expression following ibotenic acid injection. Additionally, mitogen-activated protein kinase (MAPK) family phosphorylations were inhibited after ASD treatment, implicating that the MAPK signaling pathway could be involved in the mechanism underlying neuroprotection of ASD against ibotenic acid-induced excitotoxicity.
