The involvement of magnoflorine in the sedative and anxiolytic effects of Sinomeni Caulis et Rhizoma in mice

The present study seeks to evaluate the sedative and anxiolytic effects of the 70 % ethanol extract of Sinomeni Caulis et Rhizoma (SR). The extract was orally administered to mice at dosages of 25, 50, 100, 200 or 400 mg/kg. The mice were then subjected to an array of behavioral tests to assess the sedative (open-field, rota-rod, and thiopental sodium-induced sleeping test) and anxiolytic (elevated plus maze test) effects of the substance. SR (100, 200 mg/kg) significantly reduced locomotor activity, decreased rota-rod performance, and potentiated thiopental sodium-induced sleeping in mice, all indicative of its sedative effects. SR (50, 100 mg/kg) also produced anxiolytic effects, as shown by an increase in entries and staying time on the open arm of the plus maze. SR’s sedative and anxiolytic effects were comparable to that of the benzodiazepine, diazepam. Moreover, to identify SR’s probable mechanism of action, intracellular Cl^? ion influx was observed in cultured human neuroblastoma cells. SR dose-dependently increased Cl^? influx, which was blocked by co-administration of the GABA_A receptor competitive antagonist, bicuculline. Among the major constituents of SR, only magnoflorine showed a similar increment in Cl^? influx, which was also blocked by bicuculline. Altogether, the present results suggest that SR has sedative and anxiolytic effects, probably mediated by magnoflorine through a GABAergic mechanism of action.     

Protective effects of daviditin A against endothelial damage induced by lysophosphatidylcholine

Previous investigations have indicated that endogenous inhibitors of nitric oxide synthase (NOS) such as asymmetric dimethylarginine (ADMA) may play an important role in endothelium dysfunction, and some antioxidant drugs improve endothelium function via reduction of ADMA level. The present study examined the antioxidation and endothelial protection of daviditin A, a xanthone compound. Daviditin A significantly inhibited Cu(2+)-induced low-density lipoprotein (LDL) oxidation (EC50: 38.7 microM) and scavenged 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals (EC50: 57.5 microM). Vasodilator responses to acetylcholine in rings of the isolated thoracic aorta were impaired in the presence of lysophosphatidylcholine (LPC)(5 mg/l). Daviditin A (10 or 30 microM) significantly attenuated inhibition by LPC of endothelium-dependent relaxation. Incubation of ECV304 cells with LPC (5 mg/l) for 24 h markedly elevated lactate dehydrogenase (LDH) activity and the levels of malondialdehyde (MDA) and ADMA, and decreased the content of nitric oxide (NO) and the activity of dimethylarginine dimethylaminohydrolase (DDAH). Daviditin A (1, 3 or 10 microM) significantly attenuated the increased release of LDH, increased content of MDA, and decreased level of NO induced by LPC. Daviditin A (3 or 10 microM) significantly inhibited the increased concentration of ADMA. Daviditin A (10 microM) significantly attenuated the decreased activity of DDAH. The present results suggest that daviditin A preserves endothelial dysfunction elicited by LPC, and the protective effect of daviditin A on the endothelium is related to reduction of ADMA concentration.     

Protective effects of D,L-carnitine against arrhythmias induced by lysophosphatidylcholine or reperfusion

Electrophysiological effects of lysophosphatidylcholine (50 or 100 microM) and D,L-carnitine (100 microM) were studied under control conditions and in response to simulated ischaemia and reperfusion using the superfused right ventricular free wall preparation from the guinea pig heart. Lysophosphatidylcholine, 100 microM, induced a significant depolarization of the maximum diastolic potential (MDP) in the epicardium, as well as the development of ventricular premature beats, salvos and ventricular tachycardia. Both coupled beats and abnormal automaticity were observed in lysophosphatidylcholine (100 microM)-treated preparations. Carnitine (100 microM) alone had no effect on preparations superfused with normal Tyrode solution. However, it delayed the time to onset and reduced the cumulative duration of lysophosphatidylcholine-induced arrhythmias (P less than 0.05). The incidence of lysophosphatidylcholine-induced abnormal automaticity and salvos was also significantly decreased in the presence of carnitine. Twenty minutes of simulated ischaemia caused depolarization of MDP as well as prolongation followed by block of transmural conduction. Lysophosphatidylcholine (100 microM) did not alter this response however, carnitine significantly reduced ischaemia-induced depolarization in the epicardium. All control preparations developed arrhythmic activity during 30 min of reperfusion. Carnitine accelerated recovery of MDP in the epicardium upon reperfusion, prolonged the time to onset of arrhythmic activity and reduced both its cumulative duration and incidence. In contrast, reperfusion in the presence of lysophosphatidylcholine (100 microM) significantly increased the incidence of arrhythmic activity. Carnitine exerted only minimal antiarrhythmic action when preparations were exposed to reperfusion in the presence of lysophosphatidylcholine. In conclusion, this study demonstrates that carnitine can modify various cellular mechanisms of arrhythmia induced by lysophosphatidylcholine or by reperfusion but is much less effective when lysophosphatidylcholine and reperfusion are combined.     

Coptidis Rhizoma: protective effects against peroxynitrite-induced oxidative damage and elucidation of its active components

We have investigated the protective effects of Coptidis Rhizoma against peroxynitrite (ONOO(-))-induced oxidative damage and have elucidated the active components of this preparation. In an in-vitro system, Coptidis Rhizoma extract scavenged ONOO(-) and its precursors, nitric oxide (NO) and superoxide anion (O(2)(-)). This scavenging activity was more marked for ONOO(-) than its precursors. In addition, against 3-morpholinosydnonimine-induced cellular damage, this extract significantly reduced cellular ONOO(-) formation and increased cell viability. In an in-vivo lipopolysaccharide plus ischaemia-reperfusion system that generated ONOO(-), the administration of Coptidis Rhizoma extract at 50 and 100 mg kg(-1)/day for 30 days exerted greater inhibition of ONOO(-) than NO and O(2)(-). This suggested that it acted as a direct scavenger of ONOO(-) rather than as a scavenger of its precursors. Moreover, the suppression of the activities of the antioxidative enzymes superoxide dismutase, catalase and glutathione peroxidase was significantly attenuated by the administration of Coptidis Rhizoma extract. Furthermore, the extract ameliorated renal dysfunction judged by decreasing serum urea nitrogen and creatinine levels. To elucidate the active components of Coptidis Rhizoma extract, we evaluated and compared the effects of the phenol plus alkaloid and alkaloid fractions on ONOO-induced damage. We found that the alkaloid fraction consisting of berberine, palmatine and coptisine was the most effective at protecting against ONOO(-). We confirmed that berberine (10 and 20 mg kg(-1)/day for 10 days), the main and most active alkaloid in Coptidis Rhizoma extract, was also protective, exerting NO-, O(2)(-)- and ONOO(-)-scavenging activities. This study suggested that Coptidis Rhizoma could protect against ONOO(-)-induced oxidative damage and that this effect was mainly attributable to the constituent alkaloids, especially berberine. This study is the first to demonstrate an antioxidative effect of alkaloids, including berberine, against ONOO(-)-induced damage.

Protective effects of quinaprilat and trandolaprilat,active metabolites of quinapril and trandolapril,on hemolysis induced by lysophosphatidylcholine in human erythrocytes

We examined the effects of the angiotensin converting enzyme (ACE) inhibitors captopril, enalaprilat, quinapril, and trandolapril, and their active metabolites quinaprilat and trandolaprilat, on hemolysis induced by lysophosphatidylcholine (LPC) in human erythrocytes. LPC induced hemolysis at the concentrations above the critical micelle concentration (4 microM). Propranolol, used as a reference drug, attenuated the 50% hemolysis induced by 6 microM LPC at concentrations ranging from 100 nM to 100 microM. Similarly, quinaprilat (10 microM) and trandolaprilat (10, 100 microM) significantly attenuated the LPC-induced hemolysis, but other ACE inhibitors did not. Since propranolol possesses a membrane stabilizing action correlated with high lipophilicity, it appears that the high lipophilicity of quinaprilat or trandolaprilat is responsible for the protection from the damage induced by LPC. However, quinapril and trandolapril were not effective, although both drugs have higher lipophilicity than quinaprilat and trandolaprilat. Hence, it is suggested that the high lipophilicity alone may not contribute to the protective effects of ACE inhibitors against LPC-induced hemolysis. None of ACE inhibitors attenuated the hypotonic hemolysis (60 mM NaCl), although propranolol did. Furthermore, neither propranolol (100 microM) nor quinaprilat (50 microM) and trandolaprilat (50 microM) affected LPC micelle formation, suggesting that these drugs do not directly bind to LPC. We therefore believe that the protective effects of quinaprilat and trandolaprilat on the LPC-induced hemolysis may be related physicochemically to their highly lipophilic and ACE inhibitory structures, which probably maintain erythrocyte membrane integrity by a mechanism other than ACE inhibition, prevention of LPC micelle formation or protection against osmotic imbalance.     

Protection against hydrogen peroxide induced oxidative damage in rat erythrocytes by Mangifera indica L. peel extract

Phytochemicals such as polyphenols and carotenoids are gaining importance because of their contribution to human health and their multiple biological effects such as antioxidant, antimutagenic, anticarcinogenic and cytoprotective activities and other therapeutic properties. Mango peel is a major by-product in pulp industry and it contains various bioactive compounds like polyphenols, carotenoids and others. In the present study, the protective effect of peel extracts of unripe and ripe mango fruits of two varieties namely, Raspuri and Badami on hydrogen peroxide induced hemolysis, lipid peroxidation, degradation of membrane proteins and its morphological changes are reported. The oxidative hemolysis of rat erythrocytes by hydrogen peroxide was inhibited by mango peel extract in a dose dependent manner. The IC₅₀ value for lipid peroxidation inhibition on erythrocyte ghost membrane was found to be in the range of 4.5–19.3 μg gallic acid equivalents. The mango peel extract showed protection against membrane protein degradation caused by hydrogen peroxide. Morphological changes to erythrocyte membrane caused by hydrogen peroxide were protected by mango peel extract. The results demonstrated that mango peel extracts protected erythrocytes against oxidative stress and may impart health benefits and it could be used as a valuable food ingredient or a nutraceutical product.     

The protective role of olive oil hydroxytyrosol against oxidative alterations induced by mercury in human erythrocytes

Hydroxytyrosol (HT) is a phenolic antioxidant naturally occurring in virgin olive oil. In this study, we investigated the possible protective effects of HT on the oxidative and morphological alterations induced by mercury (Hg) in intact human erythrocytes. These cells preferentially accumulate this toxic heavy metal. More importantly, Hg-induced echinocyte formation correlates with increased coagulability of these cells. Our results indicate that HT treatment (10–50 µM) prevents the increase in hemolysis and Reactive Oxygen Species (ROS) generation induced by exposure of cells to micromolar HgCl₂ concentrations as well as the decrease in GSH intracellular levels. Moreover, as indicated by scanning electron microscopy, the morphological alterations are also significantly reduced by HT co-treatment. Taken together our data provide the first experimental evidence that HT has the potential to counteract mercury toxicity. The reported effect may be regarded as an additional mechanism underlying the beneficial cardio-protective effects of this dietary antioxidant, also endowed with significant anti-atherogenic and anti-inflammatory properties.     

Protective effects of Belamcandae Rhizoma against skin damage by ameliorating ultraviolet‐B‐induced apoptosis and collagen degradation in keratinocytes

Ultraviolet‐B light (UV‐B) is a major cause of skin photoaging, inducing cell death and extracellular matrix collapse by generating reactive oxygen species (ROS). Belamcandae Rhizoma (BR), the rhizome of Belamcanda chinensis Leman, exhibits antioxidant properties, but it remains unknown whether BR extract ameliorates UV‐B‐induced skin damage. In this study, we evaluated the effects of a standardized BR extract on UV‐B‐induced apoptosis and collagen degradation in HaCaT cells. BR was extracted using four different methods. We used radical‐scavenging assays to compare the antioxidative activities of the four extracts. Cells were irradiated with UV‐B and treated with BR boiled in 70% (vol/vol) ethanol (BBE). We measured cell viability, intracellular ROS levels, the expression levels of antioxidative enzymes, and apoptosis‐related and collagen degradation‐related proteins. The irisflorentin and tectorigenin levels were measured via high‐performance liquid chromatography. BBE exhibited the best radical‐scavenging and cell protective effects of the four BR extracts. BBE inhibited intracellular ROS generation and induced the synthesis of antioxidative enzymes such as catalase and glutathione. BBE attenuated apoptosis by reducing the level of caspase‐3 and increasing the Bcl‐2/Bax ratio. BBE reduced the level of matrix metalloproteinase‐1 and increased that of type I collagen. The irisflorentin and tectorigenin contents were 0.23% and 0.015%, respectively. From these results, BBE ameliorated UV‐B‐induced apoptosis and collagen degradation by enhancing the expression of antioxidative enzymes. It may be a useful treatment for UV‐B‐induced skin damage.

The protective effects of phenolic constituents fromGastrodia elata on the cytotoxicity induced by KCl and glutamate

Seven phenolic compounds (1-7) were isolated from the tubers of Gastrodia elata. Their structures were elucidated on the basis of MS and NMR spectral data. p-Ethoxymethyl phenyl-O-beta-D-glucoside (1) was proved to be a new compound, with N-(p-hydroxybenzyl)-adenosine (7) isolated from this plant for the first time. In this study, the protective effects of the six constituents (1-6) on PC12 cells against the cytotoxicity induced by KCl and glutamate were also investigated. The viability of the PC12 cells was significantly enhanced by pretreatment with the six phenolic constituents.     

Characterization and determination of the major constituents in Belamcandae Rhizoma by HPLC-DAD-ESI-MS(n)

Belamcandae Rhizoma, derived from the rhizome of Belamcanda chinensis (L.) DC., has been used as traditional Chinese medicine for the treatment of coughing and pharyngitis. However, there have been few studies dealing with the systematic analysis of the bioactive constituents in Belamcandae Rhizoma. In this work, high performance liquid chromatography-diode array detection-electrospray ionization multiple-stage mass spectrometry (HPLC-DAD-ESI-MSⁿ) combined with liquid chromatography-time of flight-mass spectrometry (HPLC-TOF/MS) was established for profiling and characterization of multi-constituent in Belamcandae Rhizoma. The ESI-MSⁿ fragmentation behaviors of the authentic references were proposed for aiding the structural identification of components in the extract. Thirty-five flavonoids, including 30 isoflavones and five xanthones, were identified or tentatively identified by comparing their retention times, UV and MS spectra with those of authentic compounds or literature data. Twelve of the identified compounds (neomangiferin, mangiferin, tectoridin, iristectorin B, iristectorin A, iridin, tectorigenin, iristectorigenin A, irigenin, irisflorentin, irilone and dichtomitin) were determined by HPLC-DAD using a C₁₈ column. The results indicated that the developed analysis method could be employed as a rapid, effective technique for structural characterization of chemical constituents in herbal medicine. This work is expected to provide comprehensive information for the quality evaluation of Belamcandae Rhizoma, which would be a valuable reference for the further study and development of this herb and related medicinal products.

The protective effects of hydroxytyrosol against ortho-phenylphenol-induced DNA damage in HepG2 cells

Ortho-phenylphenol (OPP) has been found to cause carcinomas in the urinary tract of rats. Since OPP is a potent genotoxic compound, and used as fungicides and antibacterial agents in fruits and fruit products, search for newer, better agents for protection against toxicity of OPP is required. In this study, the chemoprotective effect of hydroxytyrosol (HT) against OPP-induced DNA damage in HepG2 cells was investigated. Comet assay was used to detect the DNA damage induced by OPP. To elucidate the possible mechanisms, we tested lysosomal membrane stability, mitochondrial membrane potential, intracellular generation of reactive oxygen species (ROS), and reduced glutathione (GSH). Results showed that HT significantly reduced the DNA strand breaks caused by OPP. Moreover, HT effectively suppressed OPP-induced ROS formation, and increased the GSH level. Lysosomal membrane and mitochondrial membrane were also protected when cells were pretreated with HT. These results suggested that the disruption of lysosomal membrane integrity and the oxidative stress, leading to DNA fragmentation, may be the mechanism of DNA damage induced by OPP. The antioxidant activity of HT may play an important part in attenuating the DNA damage of OPP.
