Schisandrin B Antagonizes Cardiotoxicity Induced by Pirarubicin by Inhibiting Mitochondrial Permeability Transition Pore (mPTP) Opening and Decreasing Cardiomyocyte Apoptosis. Front Pharmacol 2021; 12:733805. [PMID: 34721023 PMCID: PMC8554014 DOI: 10.3389/fphar.2021.733805] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Accepted: 08/30/2021] [Indexed: 11/13/2022] Open
Abstract
Objective: Pirarubicin (THP), one of the anthracycline anticancer drugs, is widely used in the treatment of various cancers, but its cardiotoxicity cannot be ignored. Schisandrin B (SchB) has the ability to upregulate cellular antioxidant defense mechanism and promote mitochondrial function and antioxidant status. However, it has not been reported whether it can resist THP-induced cardiotoxicity. The aim of this study was to investigate the effect of SchB on THP cardiotoxicity and its mechanism. Methods: The rat model of cardiotoxicity induced by THP was established, and SchB treatment was performed at the same time. The changes of ECG, cardiac coefficient, and echocardiogram were observed. The changes of myocardial tissue morphology were observed by H&E staining. Apoptosis was detected by TUNEL. The levels of LDH, BNP, CK-MB, cTnT, SOD, and MDA in serum were measured to observe the heart damage and oxidative stress state of rats. The expression of cleaved-caspase 9, pro/cleaved-caspase 3, Bcl-2/Bax, and cytosol and mitochondrial Cyt C and Bax was evaluated by western blot. H9c2 cardiomyocytes were cocultured with THP, SchB, and mPTP inhibitor CsA to detect the production of ROS and verify the above signaling pathways. The opening of mPTP and mitochondrial swelling were detected by mPTP kit and purified mitochondrial swelling kit. Results: After 8 weeks, a series of cardiotoxicity manifestations were observed in THP rats. These adverse effects can be effectively alleviated by SchB treatment. Further studies showed that SchB had strong antioxidant and antiapoptotic abilities in THP cardiotoxicity. Conclusion: SchB has an obvious protective effect on THP-induced cardiotoxicity. The mechanism may be closely related to the protection of mitochondrial function, inhibition of mPTP opening, and alleviation of oxidative stress and apoptosis of cardiomyocytes.

The Role of Traditional Chinese Medicine in the Regulation of Oxidative Stress in Treating Coronary Heart Disease. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2019; 2019:3231424. [PMID: 30918578 PMCID: PMC6409025 DOI: 10.1155/2019/3231424] [Citation(s) in RCA: 39] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/24/2018] [Revised: 01/19/2019] [Accepted: 02/04/2019] [Indexed: 02/06/2023]
Abstract
Oxidative stress has been closely related with coronary artery disease. In coronary heart disease (CHD), an excess of reactive oxygen species (ROS) production generates endothelial cell and smooth muscle functional disorders, leading to a disequilibrium between the antioxidant capacity and prooxidants. ROS also leads to inflammatory signal activation and mitochondria-mediated apoptosis, which can promote and increase the occurrence and development of CHD. There are several kinds of antioxidative and small molecular systems of antioxidants, such as β-carotene, ascorbic acid, α-tocopherol, and reduced glutathione (GSH). Studies have shown that antioxidant treatment was effective and decreased the risk of CHD, but the effect of the treatment varies greatly. Traditional Chinese medicine (TCM) has been utilized for thousands of years in China and is becoming increasingly popular all over the world, especially for the treatments of cardiovascular diseases. This review will concentrate on the evidence of the action mechanism of TCM in preventing CHD by modulating oxidative stress-related signaling pathways.

Pharmacokinetic Comparison of 20(R)- and 20(S)-Ginsenoside Rh1 and 20(R)- and 20(S)-Ginsenoside Rg3 in Rat Plasma following Oral Administration of Radix Ginseng Rubra and Sheng-Mai-San Extracts. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2017; 2017:6451963. [PMID: 28620420 PMCID: PMC5460445 DOI: 10.1155/2017/6451963] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/19/2017] [Revised: 03/19/2017] [Accepted: 03/28/2017] [Indexed: 01/16/2023]
Abstract
Ginsenosides Rh1 and Rg3, as the main bioactive components from Ginseng, are effective for prevention and treatment of cardiovascular diseases. Sheng-Mai-San (SMS), a classical complex prescription of traditional Chinese medicines, is composed of Radix Ginseng Rubra, Fructus Schisandrae, and Radix Ophiopogonis. In this research, a sensitive and specific liquid chromatography-mass spectrometric method was developed and validated for stereoselective determination and pharmacokinetic studies of 20(R)- and 20(S)-ginsenoside Rh1 and 20(R)- and 20(S)-ginsenoside Rg3 epimers in rat plasma after oral administration of Radix Ginseng Rubra or SMS extracts. The main pharmacokinetic parameters including Tmax, Cmax, t1/2, and AUC were calculated by noncompartment model. Compared with Radix Ginseng Rubra, SMS could significantly increase the content of ginsenosides Rh1 and Rg3 in the decocting process. Ginsenosides Rh1 and Rg3 following SMS treatment displayed higher Cmax, AUC(0–t), and AUC(0–∞) and longer t1/2 and tmax except for 20(R)-Rh1 in rat plasma. The results indicated SMS compound compatibility could influence the dissolution in vitro and the pharmacokinetic behaviors in vivo of ginsenosides Rh1 and Rg3, suggesting pharmacokinetic drug-drug interactions between ginsenosides Rh1 and Rg3 and other ingredients from Fructus Schisandrae and Radix Ophiopogonis. This study would provide valuable information for drug development and clinical application of SMS.

Abstract
Since about 30% of all human cancers contain mutationally activated Ras, down regulating the over-activation of Ras/MAPK pathway represents a viable approach for treating cancers. Over-activation of Ras/MAPK pathway is accompanied by accumulation of reactive oxygen species (ROS). One approach for developing anti-cancer drugs is to target ROS production and their accumulation. To test this idea, we have employed C. elegans of let-60 (gf) mutant, which contain over-activated let-60 (the homolog of mammalian ras) and exhibit tumor-like symptom of multivulva phenotype, to determine whether anti-oxidants can affect their tumor-like phenotype. Specifically we studied the effect of Shengmai formula (SM), a traditional Chinese medicine that has strong anti-oxidant activity, on the physiology of let-60 (gf) mutants. Unexpectedly, we found that SM treatment led to the opening of mitochondrial permeability transition pore by regulating cyclophilin D and then triggered oxidative stress and related signaling pathway activation, including p53, JNK, and p38/MAPK pathways. Finally, SM induced mitochondrial pathway of apoptosis and inhibited the tumor-like symptom of the multivulva phenotype of let-60(gf) mutants. Our results provide evidences to support that SM act as a pro-oxidant agent and could serve as a potential drug candidate for combating over-activated Ras-related cancer.

Abstract
Objectives: This study used repeated intravenous injections of Saeng Maek San (SMS) injection in Sprague-Dawley (SD) rats to assess the toxicity and the stability of SMS Methods: Six-week-old male and female SD rats reared by Orient bio Inc were chosen for this pilot study. They were randomly split into four groups: Group 1 (G1), the control group (0.3 mL of normal saline solution/day/animal), and Groups 2, 3 and 4 (G2, G3 and G4), the experimental groups (0.1, 0.2 and 0.3 mL/day/animal of SMS), respectively. Each animal received an intravenous injection of SMS once a day for four weeks. Clinical signs, body weight changes, and food consumption were monitored during the observation period, and urinalysis and hematology were conducted after four weeks of SMS or saline administration. Results: No deaths occurred in any of the four groups during the observation period. Compared to the control group, male and female rats in groups 3 and 4 (0.2 and 0.3 mL/animal/day) showed hemoglobinuria, but the low-dosage group (G2, 0.1 mL/animal/day) showed no significant changes in the clinical signs test. No significant changes due to SMS were observed in the experimental groups regarding body weight changes, food consumption urinalysis, or hematology. Conclusion: During this study, no mortalities were observed in any of the experimental groups and no hemoglobinuria was observed in the low dosage group (0.1 mL/animal/day) while it was intermittently observed in groups 3 and 4 (0.2 and 0.3 mL/animal/day). Thus, we suggest that the no-observed adverse-effect level (NOAEL) is 0.1 mL/animal/day in male and female SD rats.

Abstract
OBJECTIVES Shengmaisan (SMS) is a traditional Chinese medicine prescription widely used for the treatment of diverse organs in Korea. The interstitial cells of Cajal (ICCs) are pacemaker cells that play an important role in the generation of coordinated gastrointestinal (GI) motility. We have aimed to investigate the effects of SMS in the ICCs in the mouse small intestine. METHODS To dissociate the ICCs, we used enzymatic digestions from the small intestine in a mouse. After that, the ICCs were identified immunologically by using the anti-c-kit antibody. In the ICCs, the electrophysiological whole-cell patch-clamp configuration was used to record pacemaker potentials in the cultured ICCs. RESULTS The ICCs generated pacemaker potentials in the mouse small intestine. SMS produced membrane depolarization with concentration-dependent manners in the current clamp mode. Pretreatment with a Ca(2+) free solution and thapsigargin, a Ca(2+)-ATPase inhibitor in the endoplasmic reticulum, stopped the generation of the pacemaker potentials. In the case of Ca(2+)-free solutions, SMS induced membrane depolarizations. However, when thapsigargin in a bath solution was applied, the membrane depolarization was not produced by SMS. The membrane depolarizations produced by SMS were inhibited by U-73122, an active phospholipase C (PLC) inhibitors. Furthermore, chelerythrine and calphostin C, a protein kinase C (PKC) inhibitors had no effects on SMS-induced membrane depolarizations. CONCLUSIONS These results suggest that SMS might affect GI motility by modulating the pacemaker activity through an internal Ca(2+)- and PLC-dependent and PKC-independent pathway in the ICCs.

Abstract
Chronic ingestion of high concentrations of hexavalent chromium [Cr(VI)] in drinking water induces intestinal tumors in mice. To investigate the mode of action (MOA) underlying these tumors, a 90-day drinking water study was conducted using similar exposure conditions as in a previous cancer bioassay, as well as lower (heretofore unexamined) drinking water concentrations. Tissue samples were collected in mice exposed for 7 or 90 days and subjected to histopathological, biochemical, toxicogenomic, and toxicokinetic analyses. Described herein are the results of toxicokinetic, biochemical, and pathological findings. Following 90 days of exposure to 0.3–520 mg/l of sodium dichromate dihydrate (SDD), total chromium concentrations in the duodenum were significantly elevated at ≥ 14 mg/l. At these concentrations, significant decreases in the reduced-to-oxidized glutathione ratio (GSH/GSSG) were observed. Beginning at 60 mg/l, intestinal lesions were observed including villous cytoplasmic vacuolization. Atrophy, apoptosis, and crypt hyperplasia were evident at ≥ 170 mg/l. Protein carbonyls were elevated at concentrations ≥ 4 mg/l SDD, whereas oxidative DNA damage, as assessed by 8-hydroxydeoxyguanosine, was not increased in any treatment group. Significant decreases in the GSH/GSSG ratio and similar histopathological lesions as observed in the duodenum were also observed in the jejunum following 90 days of exposure. Cytokine levels (e.g., interleukin-1β) were generally depressed or unaltered at the termination of the study. Overall, the data suggest that Cr(VI) in drinking water can induce oxidative stress, villous cytotoxicity, and crypt hyperplasia in the mouse intestine and may underlie the MOA of intestinal carcinogenesis in mice.

Abstract
The aim of this study was to examine the effect of Shengmai-san (SMS) on learning and memory impairment induced by scopolamine (1 mg/kg, i.p.) in mice. The passive avoidance task (PAT) and Morris water maze (MWM) test served as the behavioral models for testing memory. To elucidate the mechanism of its cognitive-enhancing activity, the effects of SMS (2, 4, or 8 g/kg) on activities of acetylcholinesterase (AChE) and antioxidant enzymes and levels of acetylcholine (ACh) and nitrite were evaluated in brain homogenate. Tacrine (THA) (10 mg/kg, p.o.) was used as a reference drug. SMS (4 or 8 g/kg) significantly prevented scopolamine-induced impairments as measured by the PAT and MWM (probe trial session). SMS (4 or 8 g/kg) also significantly reduced the oxidative-nitrative stress, as evidenced by decreased malondialdehyde and nitrite levels and by its prevention of decreases in glutathione and superoxide dismutase levels. The activity of AChE was decreased in scopolamine-treated mice but was inhibited significantly by SMS treatment (4 or 8 g/kg) in both salt- and detergent-soluble fractions of brain homogenates. Further SMS treatment (4 or 8 g/kg) significantly increased the ACh levels in the brain homogenate to a level similar to that observed in THA treatment. Thus, the significant cognitive enhancement observed after 7 days of administration of SMS is closely related to the strong antioxidant properties of SMS in addition to its inhibition of brain AChE activity. These findings stress the critical impact of SMS on higher brain functions such as learning and memory.

Abstract
Shengmai San (SMS) has been used for the treatment of cardiovascular disease in Asia for long-time. It has been reported that SMS can protect against oxidative stress and tune immune response in patients. In this paper, a high performance liquid chromatography-diode array detection-chemiluminescence (HPLC-DAD-CL) method for on-line detection was successfully applied to screen antioxidants in complex SMS extracts. The H(2)O(2) scavenging activity of every fraction of SMS extracts was measured to evaluate each contribution to the total anti-oxidative activities of the prescription, followed by structures identification of the main active components by LC/MS/MS. HPLC-DAD-CL method was also applied for comparing the scavenging rates of main active components between the individual herbs and SMS. Interestingly, we found that the scavenging activities of main components detected in the individual herbs were different from those in SMS. The experimental data indicated that drug interactions during decocting process could result in the changes of the antioxidants' solubility. This study demonstrated that HPLC-DAD-CL on-line assay was a useful technique for rapidly screening and identifying bioactive components from complex multi-herbal prescription.

Abstract
Prevention and amelioration of Mibyou (sub-healthy condition) is the critical target for disease prevention including age-related diseases and cancer although the Mibyou condition is not yet pathologically defined. Since the oxidative stress is an underlying basic etiology associated with many diseases and aging, the psychologically induced oxidative stress, especially in the brain was supposed as one of the pathology of Mibyou. Several traditional herbal prescriptions applied for the brain disorder were found effective to prevent cerebral oxidative stress induced by ischemia/reperfusion and also under psychological distress produced by whiskers cut in mice. Shengmai San comprising three herbs, Panax ginseng, Ophiopogon japonicus and Schisandra chinensis is a traditional herbal medicine formula having a long history of using as a remedy and clinical prescription to treat coronal heart diseases. Multifunctional aspect of traditional herbal prescription was discussed in terms of preventing oxidative injury in the brain using Shengmai San as a typical prescription.

Abstract
An advanced and reliable HPLC-MS method was developed for the simultaneous quantification of eight active components (ginsenosides Rf, Rg(2), Rg(3), Rh(1) and Rh(2), gomisin A, methylophioponanone B and schizandrin) in Sheng-Mai San, a traditional Chinese medicine. The elution of multiple components was performed using a C(18) column with stepwise gradient elution. The detection of individual analytes was monitored by electrospray MS scanning from 300 to 1000 m/z in the positive ion mode, with the limits of detection of these components ranging from 0.06 to 1 microg/mL at a signal-to-noise ratio of > or =5. The intra- and inter-day accuracies ranged from 95.1 to 104.4%, and the overall precision was less than 9.3%. The recoveries of the analytes were > or =96.6%. The method was validated and found suitable for the determination of active components present in Sheng-Mai San preparation.

Abstract
Shengmai San (SMS), which is comprised of the medicinal herbs of Panax ginseng C.A. Meyer, Schisandra chinensis Baill., and Ophiopogon japonicus Ker-Gawl (2:1:2)., is a traditional Chinese medicine being used for treating coronary heart disease. The aim of this study was to investigate the effects of SMS on the plasma and liver lipids, lipid peroxidation and antioxidant systems in liver and heart of cholesterol-fed rats. Rats were fed on a high-cholesterol (0.5%) diet (control group), high-cholesterol diet containing 2% SMS (2% SMS group) and 4% SMS (4% SMS group) for four weeks. The oxidative stress marker (thiobarbituric acid reactive substances, TBARS) and antioxidant defense systems including glutathione (GSH), glutathione peroxidase (GSH-Px), glutathione-S-transferase (GST) and superoxide dismutase (SOD) activities in rat liver and heart were evaluated. Results showed that rats fed with SMS-containing diet had reduced the H(2)O(2)-induced erythrocytes susceptibility to hemolysis, and 4% SMS feeding rats had higher plasma GSH concentration compared to the animals fed with the control diet. However, SMS had no effect on plasma lipids (total cholesterol, triglyceride and high-density lipoprotein cholesterol) and TBARS concentration. On the other hand, rats fed with the 4% SMS diet reduced the hepatic cholesterol and triglyceride contents. Fecal bile acid excretion was significantly increased in rats fed with the SMS-containing diet. Higher hepatic GSH and lower TBARS concentrations were observed in rats fed with the 4% SMS diet compared with the rats fed with the control diet. No significant difference in activities of GSH-Px, GST and SOD was found in liver and heart after the SMS treatment. Results from this study indicate that the SMS may reduce hepatic lipids and lipid peroxidation in rats.

Abstract
Manganese has been known to induce neurological disorders similar to Parkinson's disease. The dysfunction of ubiquitin-proteasome system, a pathway involved in detoxification and targeting of damaged proteins, is connected with Parkinson's disease pathogenesis. Oxidative stress may be involved in Parkinson's disease, and may also be associated with manganese-induced neurotoxicity. In the present study, we determined the effects of manganese chloride on proteasome activity in PC12 cells. Furthermore, we investigated the relationship between oxidative stress and the change of proteasome activity. The proteasome activity of PC12 cells was measured by an ELISA method. Selective oxidative stress parameters, including malondialdehyde and protein carbonyl, were measured in PC12 cells treated with manganese chloride. Cell survival and apoptosis were measured by methyl thiazolyl tetrazolium and terminal transferase-mediated dUTP nick end-labeling. In our research, manganese chloride exposure inhibited the activity of proteasome and induced oxidative stress. Both can be reversed by antioxidant agent N-acetylcysteine. N-acetylcysteine also inhibited the cytotoxicity induced by manganese chloride. In conclusion, our results imply that proteasome inhibition may be associated with manganese-induced cytotoxicity in dopaminergic neurons, which may be connected with oxidative damage.

Abstract
Neurodegenerative brain disorders such as Alzheimer's disease (AD) have been well investigated. However, significant methods for the treatment of the promotion and progression of AD are unavailable to date. Recent studies suggested that the redox imbalance and the accumulation of amyloid-beta (Abeta) peptide occurring in the brain of AD patients lead to oxidatively-induced apoptotic cell death. Here, we show the effects of Shengmai-san (SMS) on Abeta-induced cytotoxicity in PC-12 cells. SMS dose-dependently attenuated the cytotoxicity by Abeta incubation and also prevented the morphological damage in neurites of the PC-12 cells. Hemeoxygenase-1 and glutathione peroxidase-1 expressions were increased by SMS pretreatment. SMS decreased the phosphorylation level of c-jun amino-terminal kinase (JNK) and the activity of caspase-3, which were enhanced by Abeta incubation. Of importance, SMS treatment promoted neurite outgrowth. These data demonstrated dual roles of SMS in PC-12 cells. SMS prevents the apoptosis through the enhancement of anti-oxidant enzymes and inhibition of the JNK signaling pathway with the promotion of nerve cell maturation, thus suggesting benefits of SMS for the treating of neurodegenerative diseases. It may also be beneficial not only for the treatment of brain disorders but also for other diseases caused by oxidative stress.

Abstract
Distress-mediated tissue oxidative stress was examined as a model of sub-healthy condition defined in traditional Chinese medicine theory. Mice were subjected to psychologically stressful conditions by whiskers removal. Under this condition, spontaneous locomotive activity was significantly enhanced in the dark (P < 0.05 versus the control mice in three different movements), and granulocytes/lymphocytes balance shifted to granulocytes. At the same time, peroxynitrite level in blood plasma increased to ∼180% from that of the control mice at 6 h after removal of the whiskers (P < 0.01), and was maintained even after 12 h. Both protein carbonyl formation and lipid peroxidation were significantly increased under this condition in brain, heart, liver and spleen at 6 h after removal of whiskers (P < 0.05 or P < 0.01), and these levels were maximized after 12 h (increased to 120–160%, P < 0.05 or P < 0.01). The oxidative tissue injuries observed at 12 h after the removal of the whiskers were effectively prevented by two traditional Chinese medicine formula: Shengmai San (SMS) and Ling Gui Zhu Gan Tang (LGZGT), when administered for 5 days before the removal of the whiskers. Therefore, this stress model is considered useful in assessing the preventive potential of antioxidants and antioxidant-based herbal mixtures in treating the pathophysiology associated with psychological or emotional distress.

Abstract
Shengmai San (SMS) is a traditional Chinese medicine (TCM) comprising three different herbal components, Panax ginseng, Ohiopogon japonicus and Fructus schisandrae and has been used for treating coronary heart diseases (Bensky and Barolet, 1990). It was shown that SMS effectively prevented cerebral oxidative injury in rats when it administered into the duodenum before cerebral ischemia-reperfusion. In the present study, we examined whether post-ischemic administration of SMS can ameliorate cerebral ischemia-reperfusion injury in rats as well. Results showed that SMS injected immediately after ischemia also prevented the ischemia-reperfusion injury, when the effect was evaluated by the formation of protein carbonyl and thiobarbituric acid reactive substance (TBARS), and the loss of glutathione peroxidase (GPX). The preventative potential of SMS was decreased rapidly dependent on the time lag until SMS was injected after ischemia. However, it was noted that intravenously administered SMS protected the oxidative injury approximately 30% even after 60 min of reperfusion in terms of protein carbonyl formation. It is thus suggested that SMS injection might be useful for preventing the progression of injury in cerebral infarction after stroke.

Abstract
In this study we used new nitrogen compounds obtained by organic synthesis whose structure predicted an antioxidant potential and then an eventual development as molecules of pharmacological interest in diseases involving oxidative stress. The compounds, identified as FMA4, FMA5, FMA7 and FMA8 differ in the presence of hydroxyl groups located in the C-3 and/or C-4 position of a phenolic unit, which is possibly responsible for their free radicals' buffering capacity. Data from the DPPH discoloration method confirm the high antiradical efficiency of the compounds. The results obtained with cellular models (L929 and PC12) show that they are not toxic and really protect from membrane lipid peroxidation induced by the ascorbate-iron oxidant pair. The level of protection correlates with the drug's lipophilic profile and is sometimes superior to trolox and equivalent to that observed for alpha-tocopherol. The compounds FMA4 and FMA7 present also a high protection from cell death evaluated in the presence of a staurosporine apoptotic stimulus. That protection results in a significant reduction of caspase-3 activity induced by staurosporine which by its turn seems to result from a protection observed in the membrane receptor pathway (caspase-8) together with a protection observed in the mitochondrial pathway (caspase-9). Taken together the results obtained with the new compounds, with linear chains, open up perspectives for their use as therapeutical agents, namely as antioxidants and protectors of apoptotic pathways. On the other hand the slight pro-oxidant profile obtained with the cyclic structures suggests a different therapeutic potential that is under current investigation.

Abstract
Salidroside (Sald), was extracted from Rhodiola rosea L, a traditional Chinese medicine which has been used for long time for anti-aging, anti-cancer and anti-oxidative stress etc. In present experiment, salidroside could protect the PC12 cell against injuries caused by exposure of PC12 cells to 2 mmol/L glutamate for 15 min followed by incubation with serum-free medium for 24 h, which resembled the excitotoxin in vivo system. Furthermore, saldroside could decrease the [Ca2+]i of PC12 cells in Mg2+-free Hanks' solution and D-Hanks' solution but there was no effect on basal [Ca2+]i in Hanks' solution. The studies also indicated that salidroside inhibited the increases of [Ca2+]i induced by KCl and glutamate. In conclusion, salidroside may protect PC12 cell against glutamate excitotoxic damage through suppressing the excessive entry of Ca2+ and the release of the calcium stores.

Abstract
Mangiferin, 2-beta-D-glucopyranosyl-1,3,6,7-tetrahydroxy-9H-xanthen-9-one, obtained directly from methanolic extracts of Bombax ceiba leaves in substantial amounts demonstrated strong antioxidant activity (EC(50) 5.8+/-0.96 mug/ml or 13.74 muM) using DPPH assay comparable to rutin, commonly used as antioxidant for medical purposes. The acetyl and cinnamoyl derivatives were found to be less active than mangiferin whereas, methyl and 3,6,7-trimethylether tetraacetate derivatives were inactive implying that for antioxidant activity, free hydroxyl groups and catechol moiety are essential. Moreover, mangiferin showed hepatoprotective activity against carbon tetrachloride induced liver injury further supporting the free radical scavenging property in the in vivo system. Additionally, plant extracts and mangiferin failed to exhibit acute anti-inflammatory activity whereas, it displayed significant analgesic effect in acetic acid-induced writhing and hot plate tests in mice. Using naloxone, it was revealed that plant extracts induced analgesia was independent of opioid receptor, whereas, mangiferin demonstrated significant interaction with it at peripheral site with a slight contribution at the neuronal level.

Abstract
Traditional Eastern Medicine (TEM) has a long history in stroke therapy and its therapeutic efficacy has been confirmed by clinical studies. Extensive experience and abundant clinical data on TEM in stroke treatment have been accumulated over the past thousand years. Basic and clinical research in TEM constitutes a potentially rich source for new drug discovery and development with the integration of TEM and Western pharmacology. In recent years, many attempts have been made to document research data from extracts of composite formulas, single herbs, or single compounds from TEM herbs, according to orthodox pharmacological actions. This article reviews herbs and prescriptions that have been documented to have a neuroprotective effect in in vitro and in vivo ischemic model systems, and the neuroprotective compounds isolated from them. I also discuss the neuroprotective mechanisms of prescriptions, herbs, and single compounds relevant to the treatment of brain ischemia, including anti-oxidant, anti-excitotoxic, and anti-inflammatory effects.
