Saurolactam Inhibits Proliferation, Migration, and Invasion of Human Osteosarcoma Cells.

Osteosarcoma is a common type of malignant bone tumor with features of osteoid formation or osteolytic lesions of bone. New therapeutic approaches are urgently needed since it lacks response to chemotherapeutic treatments. Saurolactam, a natural compound isolated from the aerial portions of Saururus chinensis, was reported to have an anti-inflammatory activity. Here, we demonstrate that saurolactam shows anti-cancer activity against human osteosarcoma cells. Saurolactam treatment inhibited proliferation of human osteosarcoma cell lines MG-63 and HOS and decreased colony formation in soft agar in a dose-dependent manner. Intraperitoneal administration of saurolactam at 25mg/kg of body weight for 21days dramatically inhibited the growth of MG-63 xenografts in nude mice. Flow cytometric analysis indicated that saurolactam treatment (20μM) led to G1 cell cycle arrest and induced apoptosis in these two cell lines. Western analysis suggested that saurolactam treatment resulted in a reduction of Akt/PKB, phospho-Ser473-Akt, c-Myc, and S-phase kinase-associated protein 2 (Skp2) in MG-63 and HOS osteosarcoma cells. Akt overexpression significantly abolished saurolactam-induced decrease in protein and phosphorylation levels of Akt, c-Myc, and Skp2 protein levels, implying that Akt inactivation was a causal mediator of saurolactam-induced inhibition of c-Myc and Skp2. Moreover, Skp2 overexpression in MG-63 cells partly abolished the growth inhibition induced by saurolactam. Saurolactam treatment repressed migration and invasion ability, and Skp2 overexpression significantly blocked these inhibitory effects of saurolactam in MG-63 Cells. The present study indicates that saurolactam might represent a new promising agent to improve osteosarcoma treatment.

Pharmacokinetics, tissue distribution, and tentative metabolite identification of sauchinone in mice by microsampling and HPLC-MS/MS methods.

Sauchinone, a biologically active lignan found in Saururus chinensis (Saururaceae), exerts various biological activities against jaundice, inflammatory disease, hepatic steatosis, and oxidative injury. Despite its diverse applications, there exists some information about sauchinone's pharmacokinetics but its tissue distribution, metabolism, and tentative metabolites have not been reported yet. Thus we investigated the pharmacokinetics of sauchinone in mice using microsampling and HPLC-MS/MS methods. Sauchinone presented linear pharmacokinetics at intravenous doses 7.5-20 mg/kg and oral doses 20-500 mg/kg. However, the metabolism of sauchinone was saturated and this agent presented nonlinear pharmacokinetics at 50 mg/kg in the intravenous study. At sauchinone 20 mg/kg the F of sauchinone was 7.76% of the oral dose despite that 77.9% of sauchinone was absorbed. This might be due to extensive metabolism of sauchinone in S9 fractions of liver and small intestine. Tentative metabolites of sauchinone by oxidation, dioxidation, methylation, demethylation, dehydrogenation, or bis-glucuronide conjugation were detected in plasma and S9 fractions of liver, intestine, and kidney. The distribution of sauchinone was considerably high (tissue-to-plasma (T/P) ratios, >1) in liver, small intestine, kidney, lung, muscle, fat, or mesentery after intravenous and oral administration and in stomach and large intestine only after oral administration. The protein binding value of sauchinone was 53.0%. These pharmacokinetic data of sauchinone provide an important basis for preclinical applications and experimental methods can be adjusted to evaluate the pharmacokinetics of natural products in mice.

Protection of Saururus Chinensis Extract against Liver Oxidative Stress in Rats of Triton WR-1339-induced Hyperlipidemia.

Saururus chinensis has been reported to contain compounds such as lignans, alkaloids, diterpenes, flavonoids, tannins, steroids, and lipids. Fermentation is commonly used to break down certain undesirable compounds, to induce effective microbial conversion, and to improve the potential nutraceutical values. Previous studies have reported that the fermentation process could modify naturally occurring constituents, including isoflavons, saponins, phytosterols, and phenols, and could enhance biological activities, specifically antioxidant and antimicrobial properties. The probiotic strains used for fermentation exert beneficial effects and are safe. In this study, the antioxidative effects of the Bacillus subtilis fermentation of Saururus chinensis were investigated in a rat model with Triton WR-1339-induced hyperlipidemia by comparing the measured antioxidative biological parameters of fermented Saururus chinensis extract to those of nonfermented Saururus chinensis extract. Fermentation played a more excellent role than nonfermentation in ultimately protecting the body from oxidative stress in the liver of the experimental rats with Triton WR-1339-induced hyperlipidemia.

Inhibitory effects of Saururus chinensis and its components on stomach cancer cells

Saururus chinensis (SC) Baill. (Saururaceae), a perennial herb commonly called Chinese lizard's tail or Sam-baekcho in Korea, has been used in the treatment of edema, gonorrhea, jaundice, and inflammatory diseases. Recently, several reports have been commissioned to examine the anti-cancer activities of this plant. In this study, we evaluated the inhibitory activity and mechanism of action on SC and its components against stomach cancer cells. SC extracts displayed cytotoxic effects on AGS cells in a dose-dependent manner. Moreover, SC increased the number of annexin V-positive apoptotic bodies and phosphorylated JNK and p38 in AGS cells. SC also down-regulated anti-apoptotic (Bcl-2) genes and up-regulated apoptotic (Bax) genes in AGS cells. We further confirmed that caspase activation plays an important role in SC-induced apoptosis in AGS cells. Furthermore, we examined erythro-Austrobailignan-6 and meso-dihydroguaiaretic acid, major active constituents of SC, which induced apoptosis in both the AGS and NCI-N87 stomach cancer cell lines. Taken together, our data provide the evidence that SC and its components induce apoptosis in stomach cancer cells, making it a potential candidate as a chemotherapeutic drug.

Attenuation of inflammatory-mediated neurotoxicity by Saururus chinensis extract in LPS-induced BV-2 microglia cells via regulation of NF-κB signaling and anti-oxidant properties.

BackgroundA Saururus chinensis Baill (SC) has been used by Native Americans, early colonists and practitioners of Korean traditional medicine for treating several diseases including cancer, rheumatoid arthritis and edema. The objective of this study was to evaluate the effects of SC extract in lipopolysaccharide (LPS)-stimulated neuroinflammatory responses in BV-2 microglial cells.MethodsThe effects of SC on the LPS–induced neuroinflammatory responses in BV-2 microglial cells were assessed by Western blotting, RT-PCR and immunofluorescence labeling techniques. DPPH and alkyl radical scavenging assay was performed to evaluate the anti-oxidant effects. Comparisons between groups were analyzed using one-way analysis of variance followed by Dunnett’s multiple comparisons test using GraphPad Prism V5.01 software.ResultsPre-treatment with SC extract (1, 5 and 10 μg/mL) significantly (p < 0.001 at 10 μg/mL) and concentration dependently inhibited LPS-induced production of nitric oxide (NO), inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2) and suppressed the inflammatory cytokine levels such as tumor necrosis factor-alpha and interleukin (IL)-6 in BV-2 microglial cells (p < 0.001 at 10 μg/mL). Further, SC suppressed the nuclear factor-kappa B (NF-κB) activation by blocking the degradation of IκB-α. SC also exhibited profound anti-oxidant effects by scavenging 1, 1-diphenyl-2-picrylhydrazyl (DPPH) (IC50: 0.055 mg/mL) and alkyl radicals (IC50: 0.349 mg/mL). High performance liquid chromatography finger printing analysis of SC revealed quercetin (QCT) as one of the major constituents compared with reference standard. QCT also inhibited the excessive release of NO, and inhibited the increased expressional levels of IL-6, iNOS and COX-2 in LPS-stimulated BV-2 cells.ConclusionsOur results indicated that SC inhibited the LPS-stimulated neuroinflammatory responses in BV-2 microglia via regulation of NF-κB signaling. The antioxidant active constituents of SC might be partly involved in delivering such effects. Based on the traditional claims and our present results SC can be potentially used in treating inflammatory-mediated neurodegenerative diseases.

Sauchinone attenuates liver fibrosis and hepatic stellate cell activation through TGF-β/Smad signaling pathway

Hepatic stellate cells (HSCs) are key mediators of fibrogenesis, and the regulation of their activation is now viewed as an attractive target for the treatment of liver fibrosis. Here, the authors investigated the ability of sauchinone, an active lignan found in Saururus chinensis, to regulate the activation of HSCs, to prevent liver fibrosis, and to inhibit oxidative stress in vivo and in vitro. Blood biochemistry and histopathology were assessed in CCl4-induced mouse model of liver fibrosis to investigate the effects of sauchinone. In addition, transforming growth factor-β1 (TGF-β1)-activated LX-2 cells (a human HSC line) were used to investigate the in vitro effects of sauchinone. Sauchinone significantly inhibited liver fibrosis, as indicated by decreases in regions of hepatic degeneration, inflammatory cell infiltration, and the intensity of α-smooth muscle actin staining in mice. Sauchinone blocked the TGF-β1-induced phosphorylation of Smad 2/3 and the transcript levels of plasminogen activator inhibitor-1 and matrix metalloproteinase-2 as well as autophagy in HSCs. Furthermore, sauchinone inhibited oxidative stress, as assessed by stainings of 4-hydroxynonenal and nitrotyrosine: these events may have a role in its inhibitory effects on HSCs activation. Sauchinone attenuated CCl4-induced liver fibrosis and TGF-β1-induced HSCs activation, which might be, at least in part, mediated by suppressing autophagy and oxidative stress in HSCs.

옥상텃밭을 이용한 약초재배 시험

ABSTRACTThis study was carried out to investigate the growth responses of medicinal plants such as Glehnia littoralis, Cryptotaenia japonica, Angelica gigas, Reynoutria japonica, Saururus chinensis, Houttuynia cordata, Ligularia fischeri, and Aralia cordata under 70%-shading and full sunlight conditions on a rooftop condition using artificial soil as a growth media. Glehnia littoralis, Cryptotaenia japonica, Ligularia fischeri, Saururus chinensis, and Houttuynia cordata showed better growth on plant height, leaf length, leaf width, petiole length and leaf number under full sunlight conditions on a rooftop condition. Cryptotaenia japonica and Houttuynia cordata had high value of Hunter's a (red-green) under full sunlight, while had lower value of L(lightness) and b(blue-yellow) than those of 70% shading condition. As an index of plant stress response, Glehnia littoralis, Reynoutria japonica, Houttuynia cordata, Ligularia fischeri showed Fv/Fm values 0.79∼0.84 under full sunlight in August, indicating low stress on plant growth. Therefore they seemed to be suitable medicinal plats for rooftop conditions. Ligularia fischeri and Reynoutria japonica showed better growth under 70% shading treatment in August, while showed high growth response under full sunlight conditions in September. The 70% shading treatment was effective for the growth of Angelica gigas, Reynoutria japonica, and Aralia cordata. Angelica gigas and Reynoutria japonica, however, showed better plant growth under

Secondary metabolites from Saururus chinensis and their chemotaxonomic significance

Phytochemical investigation of the whole plants of Saururus chinensis resulted in the isolation of two sesquiterpenes (1 and 2), five lignans (3-7), one alkaloid (8) and two steroids (9 and 10). Among them, compound 3 has not been reported as a natural product before. Compounds 1, 2, 8 and 10 were firstly reported from the family Saururaceae. The possible biosynthesis pathway for sauchinone-like neolignans (6 and 11) was also firstly proposed. Furthermore, the chemotaxonomic significance of these compounds was summarized.

Selective cytotoxicity of Saururus chinensis in glucose-deprived HT-29 human colon cancer cells

In this study, the selective cytotoxic activity of methanolic extracts of Saururus chinensis (SCE) was examined on glucose-deprived HT-29 cells. The effects of SCE on 2-deoxy-glucose (2DG) or glucose-free stressed HT-29 cells were evaluated through the MTT reduction assay, morphological observations, and the colony formation assay, in which SCE (5, 10 μg/mL) was found to be highly toxic to HT-29 cells only during glucose-deprived conditions. In addition, the mechanism of selective cytotoxic effects on SCE was assessed by Western blot analysis; SCE suppressed the accumulation of GRP78. Furthermore, apoptotic effects of SCE on glucose-deprived HT-29 cells were identified by Hoechst 33342 staining and flow cytometric analysis. In conclusion, SCE induced apoptosis in HT-29 cells under glucose-deprived conditions by down-regulation of GRP78. Cytotoxic effects on HT-29 cells were only observed during glucose deprivation, suggesting that SCE may be a target for novel therapeutic agents for treating colon cancer under glucose-deprived stress.

초미세 분쇄한 삼백초(Saururus chinensis) 추출물의 항산화, angiotensinconverting enzyme 및 xanthin oxidase 억제 활성

In this study, the biological activity of water and ethanol extracts from Saururus chinensis by ultra-fine grinding for functional food source are examined. It is more effective to use ethanol than water when extracting phenolic compounds. Approximately 2.5 times higher extraction yield were shown when it was ultra-fine grinded because the particle size decreases, thereby increasing the extraction yield. Normal grinded sample extracts showed 69.8% of DPPH inhibition effect, while fine grinded and ultra-fine grinded sample extracts showed 70.7% and 83.8% each, respectively. Normal extract, as well as fine grinded and ultra-fine grinded extracts, showed over 97% of ABTS inhibition effect, thereby indicating only a slight difference in the anti-oxidative activity with the grinding method. Higher PF was determined with fine grinded and ultra-fine grinded extracts than the normal grinded extract, while ultra-fine grinded 50% ethanol extracts showed the highest anti-oxidative activity value of 1.8 PF. The fine grinded and ultra-fine grinded particle sizes are smaller than the normal grinded particle size, thus increasing the inhibition rate of the TBARS. Furthermore, the ethanol extract was revealed to have a higher effect than the water extracts. The xanthin oxidase inhibition, on the other hand, was identified as ultra-fine grinded that led to the increase in the enzyme inhibition effect. In the angiotensin-converting enzyme, water extracts with normal grinding did not show inhibition activity, while 50% ethanol extracts showed 24% inhibition activity. Moreover, the ethanol extracts showed higher inhibition effect compared to the water extracts. Ultra-fine grinded 50% ethanol extracts showed a slight antibacterial effect on the Staphylococcus aureus and Escherichia coli, while the other extracts showed none. The result suggests that Saururus chinensis extracts by ultra-fine grinding may be more useful than normal grinding as potential sources due to anti-oxidation, angiotensin converting enzyme and xanthine oxidase inhibition.

퇴행성 골관절염에 대한 HPL-04의 효과

HanPoong Leading (HPL)-04 were prepared with different oriental medicines (balk of Kalopanax pictus balk, Chaenomelis Fructus, Angelica gigas root, Zingiber officinale, Raphanus sativus Linne and Saururus chinensis Baill.) to investigate the protective effects of HPL-04 on cartilage degradation in knee osteoarthritis (OA). Rat articular chondrocytes incubated with rhIL-1α markedly increased matrix metalloproteinase (MMP)-2 and 9 activities, decreased cell viability and reduced chondrogenic gene expression. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, MMP-2 and 9 activities and real time RT-PCR indicated that HPL-04 counteracted these harmful effects in dose-dependent manner. In addition, for experimental OA in vivo, monosodium iodoacetate (MIA, 0.5 mg/50 μL) was injected into knee joints of rats and administered HPL-04 to rats for 4 consecutive weeks after MIA treatment. The experimental data showed that treatment with HPL-04 significantly prevented of MMP-2 and 9 activities in articular cartilage. Histopathological and micro-CT evaluations of the knee joints also revealed that HPL-04 effectively amelio- rated MIA-induced degenerative OA. In conclusion, HPL-04 has potential applicability for the prevention and treatment of degenerative OA.

Potential Antiviral Lignans from the Roots of Saururus chinensis with Activity against Epstein–Barr Virus Lytic Replication

Epstein-Barr virus (EBV) is a member of the γ-herpes virus subfamily and has been implicated in the pathogenesis of several human malignancies. Bioassay-guided fractionation was conducted on an EtOAc-soluble extract of the roots of Saururus chinensis and monitored using an EBV lytic replication assay. This led to the isolation of 19 new (1-19) and nine known (20-28) lignans. The absolute configurations of the new lignans were established by Mosher's ester, ECD, and computational methods. Eight lignans, including three sesquineolignans (19, 23, and 24) and five dineolignans (3, 4, 26, 27, and 28), exhibited inhibitory effects toward EBV lytic replication with EC50 values from 1.09 to 7.55 μM and SI values from 3.3 to 116.4. In particular, manassantin B (27) exhibited the most promising inhibition, with an EC50 of 1.72 μM, low cytotoxicity, CC50 > 200 μM, and SI > 116.4. This is the first study demonstrating that lignans possess anti-EBV lytic replication activity.

Further Lignans from Saururus chinensis

Three new sauchinone analogues, sauchinones B-D (1-3), together with sauchinone (4), were isolated from the aerial part of Saururus chinensis. Structures of the new compounds were determined by extensive spectroscopic data as well as X-ray analysis. Compounds 3 and 4 inhibited nitric oxide production in lipopolysaccharide stimulated RAW 264.7 cells with IC50 values of 13.0 and 14.2 µM, respectively.

Screening of Stat3 inhibitory effects of Korean herbal medicines in the A549 human lung cancer cell line

BackgroundThe transcription factor signal transducer and activator of transcription 3 (Stat3) is constitutively activated in many human cancers. It promotes tumor cell proliferation, inhibits apoptosis, induces angiogenesis and metastasis, and suppresses antitumor host immune responses. Therefore, Stat3 has emerged as a promising molecular target for cancer therapies. In this study, we evaluated the Stat3-suppressive activity of 38 herbal medicines traditionally used in Korea. MethodsMedicinal herb extracts in 70% ethanol were screened for their ability to suppress Stat3 in the A549 human lung cancer cell line. A Stat3-responsive reporter assay system was used to detect intracellular Stat3 activity in extract-treated cells, and Western blot analyses were performed to measure the expression profiles of Stat3-regulated proteins. ResultsFifty percent of the 38 extracts possessed at least mild Stat3-suppressive activities (i.e., activity less than 75% of the vehicle control). Ethanol extracts of Bupleurum falcatum L., Taraxacum officinale Weber, Solanum nigrum L., Ulmus macrocarpa Hance, Euonymus alatus Sieb., Artemisia capillaris Thunb., and Saururus chinensis (Lour.) Baill inhibited up to 75% of the vehicle control Stat3 activity level. A549 cells treated with these extracts also had reduced Bcl-xL, Survivin, c-Myc, and Mcl-1 expression. ConclusionMany medicinal herbs traditionally used in Korea contain Stat3 activity-suppressing substances. Because of the therapeutic impact of Stat3 inhibition, these results could be useful when developing novel cancer therapeutics from medicinal herbs.

Sauchinone from Saururus chinensis protects vascular inflammation by heme oxygenase-1 induction in human umbilical vein endothelial cells

Sauchinone, a diastereomeric lignan isolated from the roots of Saururus chinensis (LOUR.) BAILL. (Saururaceae), is reported to exert a variety of biological activities such as hepatoprotective, anti-inflammatory actions and inhibitory effects on bone resorption. In this study, we investigated the effect of sauchinone in suppressing cell adhesion molecules such as vascular cell adhesion molecule-1 (VCAM-1) and intracellular adhesion molecule-1 (ICAM-1) expression in high glucose stimulated human umbilical vein endothelial cells (HUVEC). Sauchinone inhibited the phosphorylation and degradation of IκB-α, as well as the nuclear translocation of nuclear factor kappa B (NF-κB) p65 caused by the stimulation of high glucose. In addition, sauchinone induced heme oxygenase (HO)-1 expression through nuclear translocation of nuclear factor E2-related factor 2 in HUVEC. The effects of sauchinone on the high glucose-induced expression of VCAM-1 and ICAM-1 and nuclear translocation of NF-κB p65 were partially reversed by transfection of the cells with HO-1 siRNA. These findings suggest that sauchinone-induced HO-1 expression plays a key role in the vascular protective effects of sauchinone in HUVEC.

N-Hexane에 의한 삼백초 추출물의 항균 및 항바이러스 활성

This study was conducted to investigate the antimicrobial, antivirus properties of Saururus chinensis extracts. The n-hexane extracts from Saururus chinensis showed the active antimicrobial activity against gram-positive bacteria. Minimum inhibitory concentration (MIC) of Saururus chiensis n-hexane extracts was 1.25 mg/ml against B. subtilis and 2.5 mg/ml against S. aureus. The cytotoxicity effects on MDBK (Madin-Darby bovine kidney) cell were observed at the various n-hexane extract concentrations. In <TEX>$TCID_{50}$</TEX> assay, 0.6 mg/ml of n-hexane extracts decreased BVD (bovine viral diarrhea) virus by 1.4 log, whereas other extracts did not show antiviral activity. In this study, The results suggested that n-hexane extracts and fractions of Saururus chinensis can be a candidate materal of feed additive to chemical antibiotics and antivirus substances.

Effect of hydrothermal treatment on the antioxidant activity of Sambaekcho (Saururus chinensis) leaves

Sambaekcho (Chinese lizard’s tail; Saururus chinensis) is one of widely used plants in oriental traditional medicine. Hydrothermal treatment of sambaekcho leaves was carried out at 3 different temperatures (100, 110, and 120°C) for 3 different times (15, 30, and 60 min), and antioxidant activities of the extracts were evaluated by determining total phenol content (TPC) and DPPH radical scavenging activity. The highest TPC and DPPH radical scavenging activity of the extracts were observed at 120°C for 30 min with the values of 61.25 mg gallic acid equivalents/g sambaekcho powder and 59.41%, respectively. The highest amount of quercetin, a well-known polyphenolic compound of sambaekcho, in the extracts was detected at 110oC for 60 min with the value of 3.13 μg/mL. These results indicated that appropriate temperature and time might be important for extraction with high antioxidant activity and physiologically important compounds from sambaekcho leaves.
