This study aimed to elucidate pharmacological activities of Cordyceps militaris. The 70% ethanolic extracts of cultured mycelia (CME) and fruiting bodies (FBE) of Cordyceps militaris were prepared. CME was able to directly scavenge the stable free radical diphenyl-2-picrylhydrazyl (DPPH), indicating its antioxidant activity. Both CME and FBE showed topical anti-inflammatory activity in the croton oil-induced ear edema in mice. CME was found to contain acute anti-inflammatory activity, which was evaluated using the carrageenin-induced edema, and also strong antinociceptive activity in writhing test. CME and FBE contain potent inhibitory activity on the chick embryo chorioallantoic membrane (CAM) angiogenesis in a dose-dependent manner. Cordycepin, a metabolite of Cordyceps militaris, appeared to be at least partly responsible for its anti-inflammatory and anti-angiogenic activities. CME concentration-dependently inhibited the NO production and iNOS expression upon stimulation by lipoposaccharide in RAW 264.7, a murine macrophage cell line. In brief, we demontrate that Cordyceps militaris possesses anti-inflammatory and antinociceptive activites, and related antioxidant, anti-angiogenic, and NO production-inhibitory activities.  相似文献

This work aimed to elucidate the anti-inflammatory mechanism of the n-BuOH subfraction (PL) prepared from fruiting bodies of Phellinus linteus. PL induced heme oxygenase-1 (HO-1) of the RAW264.7 macrophages in concentration- and time-dependent manner. It suppressed induction of inducible nitric oxide synthase (iNOS) and subsequent production of nitric oxide (NO) through down-regulation of iNOS promoter activity in lipopolysaccharide (LPS)-stimulated macrophages. Zn(II) protoporphyrin IX (ZnPP), a specific inhibitor of HO-1, partly blocked suppression by PL on iNOS promoter activity and NO production, which were elevated in LPS-stimulated macrophages. LPS was able to enhance NO production via reactive oxygen species (ROS) generation, c-Jun NH(2)-terminal kinase (JNK) and c-Jun induction. ZnPP prevented PL from down-regulating ROS generation and JNK activation in LPS-stimulated macrophages. Taken together, PL shows its anti-inflammatory activity via mediation of HO-1 in an in vitro inflammation model.  相似文献

The mushroom Phellinus linteus has been known to exhibit potent biological activity. In contrast to the immuno-potentiating properties of Phellinus linteus, the anti-inflammatory properties of Phellinus linteus have rarely been investigated. Recently, ethanol extract and n-BuOH fractions from Phellinus linteus were deemed most effective in anti-inflammatory activity in RAW 264.7 macrophages. The regulatory mechanisms of Phellinus linteus butanol fractions (PLBF) on the pharmacological and biochemical actions of macrophages involved in inflammation have not been clearly defined yet. In the present study, we tested the role of PLBF on anti-inflammation patterns in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophage cells. To investigate the mechanism by which PLBF inhibits NO and PGE2 production as well as inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression, we examined the activation of IkappaB and MAPKs in LPS-activated macrophages. PLBF clearly inhibited nuclear translocation of NF-kappaB p65 subunits, which correlated with PLBF's inhibitory effects on IkappaBalpha phosphorylation and degradation. PLBF also suppressed the activation of mitogen-activated protein (MAP) kinases including p38 and stress-activated protein kinase/c-Jun NH2-terminal kinase (SAPK/JNK). Furthermore, macrophages stimulated with LPS generated ROS via activation of membrane-bound NADPH oxidase, and ROS played an important role in the activation of nuclear factor-kappaB (NF-kappaB) and MAPKs. We demonstrated that PLBF directly blocked intracellular accumulation of reactive oxygen species in RAW 264.7 cells stimulated with LPS much as the NADPH oxidase inhibitors, diphenylene iodonium, and antioxidant pyrrolidine dithiocarbamate did. The suppression of NADPH oxidase also inhibited NO production and iNOS protein expression. Cumulatively, these results suggest that PLBF inhibits the production of NO and PGE2 through the down-regulation of iNOS and COX-2 gene expression via ROS-based NF-kappaB and MAPKs activation. Thus, PLBF may provide a potential therapeutic approach for inflammation-associated disorders.  相似文献

The aqueous, ethanolic and chloroform extracts and two prenylated isoflavones: scandenone (I) and auriculasin (II), isolated from the fruits of Maclura pomifera (Rafin.) Schneider, were investigated for their in vivo anti-inflammatory and antinociceptive activity. For the anti-inflammatory activity, both carrageenan-induced hind paw edema and 12-O-tetradecanoyl-13-acetate (TPA)-induced mouse ear edema models and for the antinociceptive activity, p-benzoquinone-induced abdominal constriction test were used. Scandenone, the chloroform and the ethanolic extracts were shown to possess antinociceptive activity and anti-inflammatory activity on carrageenan-induced hind paw edema model at 100 mg/kg dose. The same compound and the extract were also found to be highly active in (TPA)-induced mouse ear edema model whereas auriculasin and the H(2)O extract showed to be inactive in all of the assays.  相似文献

Antinociceptive, anti-inflammatory and acute toxicity of the aqueous infusion and ethanolic maceration extracts of the aerial parts of Zataria multiflora Boiss were studied in mice and rats. Antinociceptive activity was done using hot-plate and writhing tests. The effect of the extracts against acute inflammation was studied by vascular permeability increased by acetic acid and xylene induced ear edema in mice. The activity of the extracts against chronic inflammation was assessed by the cotton pellet test in rats. LD50 of the infusion and maceration extract was 3.85 and 3.47 g/kg, respectively. Intraperitoneal injection of both extracts in mice showed significant and dose-dependent antinociceptive activity. Naloxone, an opioid antagonist, pretreatment inhibited the antinociceptive activity of the extracts. The extracts exhibited antinociceptive activity against acetic acid induced writhing which was partially blocked by naloxone. Both extracts did not show remarkable activity against acute inflammation induced by acetic acid in mice. In the xylene ear edema, Z. multiflora Boiss extracts showed significant activity in mice. In the chronic inflammation the efficacy of the extracts was more than in acute inflammation. It is concluded that aqueous infusion and maceration of the aerial parts of Z. multiflora Boiss have antinociceptive effect and this may be mediated by opioid receptors. The extracts showed also anti-inflammatory effect against acute and chronic inflammation.  相似文献

Cecropia pachystachya is widely used in the traditional medicine as anti‐inflammatory, antitusive, expectorant, antiasthmatic and hypoglycemic. It is also commercially available to treat skin cancer. To validate some of the popular uses of this species, its methanol leaves extract (CPM) was tested for anti‐inflammatory, antinociceptive and cytotoxic effects. The anti‐inflammatory activity was evaluated by croton oil‐induced ear edema test. When used orally, the anti‐inflammatory effect of CPM at 300 mg/kg was similar to that of indomethacin with 53% inhibition of the ear edema. Also, results on topical treatment were similar to that of dexamethasone with 83% inhibition of the edema. To evaluate the antinociceptive activity, acetic acid‐induced writhing and formalin‐induced pain tests were employed. CPM (100 and 300 mg/kg) reduced the number of writhing by 61% and 67%, respectively. In both doses, the activity was comparable to the reference drug, indomethacin. The oral administration of CPM was ineffective in the first phase of formalin test but exhibited great effects on the second phase decreasing the licking time by 85% at 300 mg/kg. The cytotoxic potential of CPM was also investigated against HL60, HL60.bcl2 and Jurkat tumor cell lines and showed an inhibition of more than 50% of cell proliferation. The flavones orientin and isoorientin were detected in CPM. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

The n-hexane, diethylether, ethyl acetate and methanol extracts from roots, leaves, stems and flowers with young leaves of Daphne pontica L. (Thymelaeaceae) were investigated for their in vivo anti-inflammatory and antinociceptive activities. For the anti-inflammatory activity assessment, carrageenan-induced hind paw edema, PGE(2)-induced hind paw edema and 12-O-tetradecanoyl-13-acetate (TPA)-induced mouse ear edema models and for the antinociceptive activity, p-benzoquinone-induced abdominal constriction test were used. Only ethyl acetate extracts of the roots showed significant anti-inflammatory activity on carrageenan-induced (22.7-32.0% inhibition) and PGE(2)-induced hind paw edema (3.2-27.3% inhibition) as well as 12-O-tetradecanoyl-13-acetate (TPA)-induced mouse ear edema (47.8-43.3% inhibition) models at 50 mg/kg dose without inducing any apparent gastric lesion or acute toxicity, whereas the other extracts were shown to be ineffective. In addition to roots, ethyl acetate extracts of the stems exhibited 19.5-29.9%; 5.3-23.9%; 36.6-28.1% inhibition on carrageenan-induced and PGE(2)-induced hind paw edema as well as 12-O-tetradecanoyl-13-acetate (TPA)-induced mouse ear edema models, respectively. On the other hand, none of the extracts showed any significant antinociceptive activity.  相似文献

Phellinus linteus (Berkeley & Curtis) Teng, a well-known fungus of the genus Phellinus in the family of Hymenochaetaceae, is being increasingly used to treat a wide variety of disease processes such as oral ulcer, gastroenteric disorder, inflammation, lymphatic disease, and various cancers. However, the mechanism underlying its anti-oral cancer effect is poorly understood. In the present study, we prepared the ethanol extract of Phellinus linteus as a crude drug, and then obtained the active component hispolon by bioassay-guided isolation. Hispolon showed a dose-dependent inhibition of human epidermoid KB cell proliferation with IC50 of 4.62+/-0.16 microg/ml. Furthermore, it was revealed that hispolon could induce human epidermoid KB cell apoptosis with the characteristic of a DNA ladder, and with a significant increase of sub-G1. This process was accompanied by the collapse of mitochondrial membrane potential, the release of cytochrome c and the activation of Caspase-3. These results demonstrated that hispolon induced the death of KB cells through a mitochondria mediated apoptotic pathway. We propose that Phellinus linteus and its effective components could be used as an anti-oral cancer drug for future studies.  相似文献

Various fractions of the ethanol extract from the root wood of Cudrania cochinchinensis var. gerontogea (Moraceae) were evaluated for their anti-inflammatory effects on carrageenan-induced edema and hepatoprotective activities on carbon tetrachloride (CCl4)-induced and D-galactosamine-(D-GalN) induced acute hepatotoxicity in rats. The fractions (n-hexane, CHCl3, EtOAc, n-BuOH, and H2O) displayed significant inhibitory activity against carrageenan-induced edema, and the active anti-inflammatory components were further localized in the n-BuOH fraction, which exhibited the greatest anti-inflammatory effect, an effect 5% greater than indomethacin (which was used as a standard reference substance). Each fraction exerted a significant hepatoprotective effect by reducing enzymatic alteration (sGOT and sGPT) and by improving hepatic lesions, including liver centrilobular inflammation, cell necrosis, fatty change, ballooning degeneration in CCl4-induced acute hepatitis; and necrosis of the portal area in D-GalN-induced acute liver injury. The n-BuOH and EtOAc fractions had the greatest hepatoprotective effects on CCl4-induced liver injury; in contrast, the CHCl3 fraction was most potent against D-GalN intoxication, which is comparable to silymarin, as a recognized hepatoprotective drug.  相似文献

Studies on carrageenin-induced rat paw edema, yeast-induced hyperthermia in rat and writhing response induced by acetic acid in mice showed that the alcoholic extract of stems of Tabernaemontana pandacaqui (T. pandacaqui) has significant anti-inflammatory, antipyretic and antinociceptive activities. These activities are due to alkaloidal components since they were also observed when the crude alkaloidal (CA) fraction separated from alcoholic extract was tested in the same models.  相似文献

Serjania erecta Radlk (Sapindaceae), commonly called cinco-folhas or cipó-cinco-folhas in Brazil, is thought to be effective for treating several inflammatory diseases. In order to verify the topical anti-inflammatory effect of Serjania erecta, hydroalcoholic extract and fractions were obtained by extraction in solvents of increasing polarity and were tested in mouse models using croton-oil-induced inflammation. Our findings showed that topical application of Serjania erecta hydroalcoholic extract (0.01-3.0 mg/ear), and the dichloromethane (0.03-1.0 mg/ear), ethyl acetate (0.03-1.0 mg/ear), and hexane (0.003-1.0 mg/ear) fractions revealed significant activity, causing a dose-dependent reduction of croton-oil ear edema (ID(50)=0.14 mg/ear, 0.23 mg/ear, 0.14 mg/ear, 0.04 mg/ear, respectively). The extract and all tested fractions also decreased tissue myeloperoxidase activity (indicative of polymorphonuclear leukocytes influx) in mouse-ears treated with croton oil with a maximum inhibition of 72% at 3.0 mg/ear for the hydroalcoholic extract and 81%, 78%, and 83% at 1.0mg/ear for dichloromethane, ethyl acetate and hexane fractions, respectively. As expected, dexamethasone (0.05 mg/ear) was effective in inhibiting both edema and myeloperoxidase activity (99% and 82%, respectively). In conclusion, our results indicate a topical anti-inflammatory effect for the species of Serjania studied.  相似文献

Torreya grandis (Taxaceae) was studied for antinociceptive and anti-inflammatory effects. Leaves were extracted with 80% ethanol at 80 °C for 3 h and fractionated with petroleum ether, chloroform, ethylacetate and n-butanol. The aqueous ethanolic extract (aq.EE), ethylacetate fraction (EaF) and butanol fraction (BtF) at the doses of (100 and 200 mg/kg, i.g.) body weight were used for study. Evaluation of antinociceptive activity was carried out by acetic acid-induced writhing response and formalin-induced paw licking time in the first and second phases of mice. The paw edema induced by formalin- and xylene-induced ear edema were used to assess anti-inflammatory activity. It was found that Torreya grandis extract and fractions at the doses of (100 and 200 mg/kg, i.g.) were significantly attenuated the writhing responses induced by acetic acid and second phase of pain response induced by subplantar injection of formalin in mice. In addition, these extract and fractions inhibiting the formaldehyde-induced arthritis as well as xylene-induces edema prolifically. From acute oral toxicity studies no mortality was pragmatic even at highest dose (2500 mg/kg, i.g.). Furthermore, our phytochemical studies indicated that the aq. ethanolic extract of leaves contains alkaloids, flavonoids, tannins, terpenoids and saponins. The results provide justification for the folkloric uses of Torreya grandis in the treatment of analgesic and inflammatory-based diseases across the China.  相似文献

This study aimed to elucidate anti-angiogenic activity of Ulmus davidiana var. japonica that has been widely used in folk medicine. The methanol extract (UDE) of Ulmus davidiana var. japonica concentration-dependently displayed a strong inhibition in the chick chorioallantoic membrane (CAM) angiogenesis. The n-butanol fraction of UDE and subsequent 30% MeOH subfraction were identified to be most responsible for the anti-angiogenic activity.  相似文献

The croton oil-induced mouse ear oedema test, acetic acid-induced abdominal writhing, and carrageenan-induced peritonitis were used to study the anti-inflammatory effects of the crude ethanol extract and its alkaloid fraction from Solanum lycocarpum fruits. The alkaloid fraction induced a dose-dependent reduction in ear oedema formation and leukocyte migration, suggesting that S. lycocarpum fruits may contain steroidal alkaloids accounting for the anti-inflammatory effect of the crude ethanol extract.  相似文献

Anti-inflammatory activity of Sedum kamtschaticum   总被引:1,自引:0,他引:1  
Sedum kamtschaticum Fischer (Crassulaceae) has been used as a folk medicine in North-East Asia for treating inflammatory disorders. The present investigation was carried out to establish in vivo anti-inflammatory activity and cyclooxygenase-2 modulating activity of this plant material. The methanol extract of Sedum kamtschaticum significantly inhibited mouse croton oil-induced ear edema (24–47% inhibition at 50–400 mg/kg) and rat paw edema (24–30% inhibition at 400–800 mg/kg) by oral administration. Prednisolone (10 mg/kg) showed 54 and 36% inhibition in the same animal models, respectively. Sedum kamtschaticum also showed significant inhibitory activity against mouse ear edema induced by multiple treatment of phorbol ester for 3 days. In addition, Sedum kamtschaticum exhibited potent analgesic activity against mouse acetic acid-induced writhing (IC50=125 mg/kg), while aspirin (200 mg/kg) showed 57% inhibition. Using lipopolysaccharide-treated RAW 264.7 cells, down-regulation of cyclooxygense-2 expression was found to be one of the cellular action mechanisms of anti-inflammation by Sedum kamtschaticum.  相似文献

Extracts obtained from the root and aerial parts of various Eryngium (Apiaceae) species are used as folk remedy worldwide for the treatment of various inflammatory disorders. Ethanolic and aqueous extracts obtained from either aerial parts or roots of eight Eryngium species growing in Turkey, i.e., were evaluated for their in vivo anti-inflammatory and antinociceptive activities. Eryngium campestre, Eryngium creticum, Eryngium davisii, Eryngium falcatum, Eryngium isauricum, Eryngium kotschyi, Eryngium maritimum, and Eryngium trisectum. For the antinociceptive activity assessment p-benzoquinone-induced writhing test, and for anti-inflammatory activity carrageenan-induced hind paw oedema and TPA-induced ear oedema tests were employed in mice. According to the results of investigations, except Eryngium falcatum extracts, ethanol extracts either from the aerial parts or roots of Eryngium species showed apparent anti-inflammatory and antinociceptive activity. In spite of potent activity of the ethanol extract from Eryngium isauricum aerial parts was induced gastric damage. Aerial parts and roots of Eryngium maritimum and Eryngium kotschyi were found to possess most promising activities without including any apparent gastric damage.  相似文献
