Abstract
We have developed a new method to simultaneously determine five marker compounds in Menthae Herba via HPLC/PDA - including hesperidin (1), rosmarinic acid (2), diosmin (3), didymin (4) and buddleoside (5). The newly developed method was successfully used to analyse for two species (Mentha arvensis L. and Mentha haplocalyx Briq.) of Menthae Herba, and the satisfactory results were obtained from the validation of developed method. The pattern analysis could greatly discriminate between M. arvensis L. and M. haplocalyx Briq. In conclusion, the proposed HPLC/PDA method is suitable for quality evaluation of Menthae Herba.

Abstract
A new HPLC/UV method has been developed for the simultaneous quantitative determination of four major components in Eucommiae cortex, namely geniposidic acid (1), geniposide (2), pinoresinol di-O-β-D-glucopyranoside (3), and liriodendrin (4). Simultaneous separations of these four components were achieved on a J'sphere ODS C(18) column (250 × 4.6 mm, 4 µm). The elution was done using water with 0.1% phosphoric acid (A) and acetonitrile with 0.1% phosphoric acid (B) in a two-step elution of the mobile phase at a flow rate of 1.0 mL/min and a wavelength of 230 nm. The method was validated for linearity, recovery, precision, accuracy, stability and robustness. All calibration curves showed good linear regression (r(2) > 0.999) within the test ranges. This method showed good recovery and reproducibility for the quantification of these four components in 85 species of Eucommiae cortex. The intra-day and inter-day precisions were lower than 0.53% (as a relative standard deviation, RSD) and accuracies between 93.00 and 106.28% for all standards. The results indicate that the established HPLC/UV method is suitable for quantitation and quality evaluation of Eucommiae cortex.

Abstract
The flower bud of Tussilago farfara L., called Farfarae Flos, has traditionally been used in Oriental medicine for the treatment of bronchitis and asthma. To establish a standard for quality control as well as the reliable identification of Farfarae Flos, the contents of five standards, rutin (1), isoquercetin (2), 3,5-dicaffeoylquinic acid (3), tussilagone (4), and tussilagonone (5), were determined by quantitative high-performance liquid chromatography (HPLC)/photodiode array (PDA) analysis. The five standards were separated on a YoungJinBioChrom Aegispak C18-L (250-mm×4.6-mm, 5-µm) column by gradient elution using 0.03% trifluoroacetic acid in water (A), with acetonitrile (B) as the mobile phase. The flow rate was 1.0 mL/min, and the UV detector wavelength was set at 220 nm. The method was successfully used in the analysis of Farfarae Flos from different geographic origins with relatively simple conditions and procedures, and the results demonstrated satisfactory linearity, recovery, precision, accuracy, stability, and robustness. The HPLC analytical method for pattern recognition analysis was validated by repeated analysis of 62 Farfarae Flos samples. This result indicated that the established HPLC/PDA method is suitable for quantitation and pattern recognition analyses for the quality evaluation of Farfarae Flos.

Abstract
To establish a standard of quality control for Perillae Folium (Lamiaceae Family), four standard compounds including rosmarinic acid, elemicin, perillaldehyde, and dillapiole were evaluated by high-performance liquid chromatography (HPLC)/photodiode array (PDA). The four standards were analyzed with a Phenomenex Kinetex C18 (250 × 4.6 mm, 5 μm) column by gradient elution using 0.1 % formic acid in water and methanol as the mobile phase. The standards were quantified by HPLC/PDA from Perillae Folium, which included the leaf and twig of Perilla frutescens L. Britton var. acuta (Thunb.) Kudo or Perilla frutescens Britton var. crispa Decne. The method was successfully used in the analysis of Perillae Folium, and the linearity, recovery, precision, accuracy, stability, and robustness were satisfactory according to the validation results. In Perillae Folium samples, the average contents (wt%) of rosmarinic acid, elemicin, perillaldehyde, and dillapiole were 0.540, 0.059, 0.050, and 0.056 %, respectively. The results indicate that the established HPLC/PDA method is suitable for the quantitation and quality evaluation of Perillae Folium.

Abstract
The aim of this study was to determine whether britanin, isolated from the flowers of Inula japonica (Inulae Flos), modulates the generation of allergic inflammatory mediators in activated mast cells. To understand the biological activity of britanin, the authors investigated its effects on the generation of prostaglandin D2 (PGD2), leukotriene C4 (LTC4), and degranulation in IgE/Ag-induced bone marrow-derived mast cells (BMMCs). Britanin dose dependently inhibited degranulation and the generations of PGD2 and LTC4 in BMMCs. Biochemical analyses of IgE/Ag-mediated signaling pathways demonstrated that britanin suppressed the phosphorylation of Syk kinase and multiple downstream signaling processes, including phospholipase Cγ1 (PLCγ1)-mediated calcium influx, the activation of mitogen-activated protein kinases (MAPKs; extracellular signal-regulated kinase 1/2, c-Jun NH2-terminal kinase and p38), and the nuclear factor-κB (NF-κB) pathway. Taken together, the findings of this study suggest britanin suppresses degranulation and eicosanoid generation by inhibiting the Syk-dependent pathway and britanin might be useful for the treatment of allergic inflammatory diseases.

Abstract
Emodin, a naturally occurring anthraquinone derivative isolated from Polygoni cuspidati radix, has several beneficial pharmacologic effects, which include anti-cancer, anti-diabetic, and anti-inflammatory activities. In this study, the authors examined the effect of emodin on the production of proinflammatory cytokines, such as, tumor necrosis factor (TNF)-α and interleukin (IL)-6, in mouse bone marrow-derived mast cells (BMMCs) stimulated with phorbol 12-myristate 13-acetate (PMA) plus the calcium ionophore A23187. To investigate the mechanism responsible for the regulation of pro-inflammatory cytokine production by emodin, the authors assessed its effects on the activations of transcriptional factor nuclear factor-κB (NF-κB) and mitogen-activated protein kinases (MAPKs). Emodin attenuated the nuclear translocation of (NF)-κB p65 and its DNA-binding activity by reducing the phosphorylation and degradation of IκBα and the phosphorylation of IκB kinase B (IKK). Furthermore, emodin dose-dependently attenuated the phosphorylations of MAPKs, such as, extracellular signal-regulated kinase 1/2 (ERK1/2), p38 MAP kinase, and the stress-activated protein kinases (SAPK)/c-Jun-N-terminal kinase (JNK). Taken together, the findings of this study suggest that the anti-inflammatory effects of emodin on PMA plus A23187-stimulated BMMCs are mediated via the inhibition of NF-κB activation and of the MAPK pathway.

Abstract
Two rapid and simple HPLC methods with UV detector to determine three main compounds (magnoflorine, spinosin and 6′′′-feruloyl spinosin) and evaporative light scattering detector (ELSD) to determine jujuboside A were developed for the chemical analyses of Zizyphi Semen. Magnoflorine, spinosin, and 6′′′-feruloyl spinosin were separated with an YMC J’sphere ODS-H80 column (250 mm × 4.6 mm, 4 μm) by the gradient elution followed by the isocratic elution using methanol with 0.1 % formic acid and water with 0.1 % formic acid as the mobile phase. The flow rate was 1.0 mL/min. Jujuboside A was separated by HPLC–ELSD with YoungJinBioChrom Aegispak C18-L column (250 mm × 4.6 mm, 5 μm) column in a gradient elution using methanol with 0.1 % formic acid (A) and water with 0.1 % formic acid as the mobile phase. These two methods were fully validated with respect to linearity, precision, accuracy, stability, and robustness. These HPLC methods were applied successfully to quantify four compounds in a Zizyphi Semen extract. The HPLC analytical methods were validated for pattern recognition analysis by repeated analysis of 91 seed samples corresponding to 48 Zizyphus jujuba var. spinosa (J01–J48) and 43 Zizyphus mauritiana (M01–M43). The results indicate that these methods are suitable for a quality evaluation of Zizyphi Semen.

Abstract
A rapid and simple high-performance liquid chromatography (HPLC) method with evaporative light scattering detection (ELSD) was developed for the determination of betaine from Lycii Fructus. Betaine was separated with an Atlantis hydrophilic interaction liquid chromatography silica column (4.6 × 150 mm, 5 μm, 100 Å) by isocratic elution using 30 mM ammonium acetate buffer and acetonitrile (20:80, v/v %) as the mobile phase. The flow rate was 1.0 mL/min, and the temperature for the spray chamber and drift tube was set at 30 and 50 °C, respectively. The method was fully validated with respect to linearity, precision, accuracy, stability and robustness. The HPLC/ELSD method was applied successfully to the quantification of betaine in the extract of Lycii Fructus. The HPLC analytical method for pattern recognition analysis was validated by repeated analysis of twenty-six L. barbarum L. from China (BC01-BC26), 3 L. barbarum L. (BJ27-BJ29) from Japan, 12 L. chinense Miller from China (CC30-CC41) and 51 L. chinense Miller samples (CK42-CK92) from Korea. The results indicate that the established HPLC/ELSD method is suitable for quality evaluation of Lycii Fructus.

In this study, quantitative and pattern recognition analyses were developed using HPLC/UV for the quality evaluation of Dipsaci Radix. For quantitative analysis, five major bioactive compounds were assessed. The separation conditions employed for HPLC/UV were optimized using ODS C18 column (250 × 4.6 mm, 5 μm) with a gradient of acetonitrile and water as the mobile phase at a flow rate of 1.0 mL/min and a detection wavelength of 212 nm. These methods were fully validated with respect to linearity, accuracy, precision, recovery, and robustness. The HPLC/UV method was applied successfully to the quantification of five major compounds in the extract of Dipsaci Radix. The HPLC analytical method for pattern recognition analysis was validated by repeated analysis of 17 Dipsaci Radix and four Phlomidis Radix samples. The results indicate that the established HPLC/UV method is suitable for quantitative analysis.

Abstract
The authors investigated the effect of manassantin B (Man B) isolated from Saururus chinensis (S. chinensis) on cyclooxygenase-2 (COX-2)-dependent prostaglandin D2 (PGD2) generation in mouse bone marrow derived-mast cells (BMMCs). Man B inhibited the generation of PGD2 dose-dependently by inhibiting COX-2 expression in immunoglobulin E (IgE)/Ag-stimulated BMMCs. To elucidate the mechanism responsible for the inhibition of COX-2 expression by Man B, the effects of Man B on the activation of nuclear factor-kappaB (NF-κB), a transcription factor essential and mitogen-activated protein kinases (MAPKs) for COX-2 induction, were examined. Man B attenuated the nuclear translocation of NF-κB p65 and its DNA-binding activity by inhibiting inhibitors of kappa Bα (IκBα) degradation and concomitantly suppressing IκB kinase (IKK) phosphorylation. In addition, Man B suppressed phosphorylation of MAPKs including extracellular signal-regulated kinase 1/2 (ERK1/2), c-Jun NH2-terminal kinase (JNK) and p38. It was also found that Man B suppressed Fyn kinase activation and consequent downstream signaling processes, including those involving Syk, Gab2, and Akt. Taken together, the present results suggest that Man B suppresses COX-2 dependent PGD2 generation by primarily inhibiting Fyn kinase in FcεRI-mediated mast cells.

Abstract
Little is known about the biological properties of britanin, which is isolated from the flowers of Inula japonica (Inulae Flos). Based on our previous studies that Inulae Flos had anti-inflammation and anti-asthmatic activities, we tried to find the bioactive compounds from it. In this study, the anti-inflammatory effects of britanin on the inflammatory mediators as well as on nuclear factor (NF)-кB and mitogen-activated protein (MAP) kinase activation were evaluated in RAW 264.7 cells. Britanin inhibited the production of nitric oxide (NO) and prostaglandin E2 (PGE2) along with the expression of inducible NO synthase (iNOS) and cyclooxygenase (COX)-2 in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. In addition, britanin reduced the release of pro-inflammatory cytokines, such as TNF-α, IL-1β, and IL-6. Furthermore, the phosphorylations of MAP kinases (p38 and JNK) in LPS-stimulated RAW 264.7 cells were suppressed by britanin. Moreover, britanin inhibited the NF-κB activation induced by LPS, which was associated with the abrogation of IκBα degradation and subsequent decreases in nuclear p65 levels. This study suggests that the anti-inflammatory activities of britanin might be attributed to the inhibition of iNOS and COX-2 and cytokine expression at least in part, through the attenuation of the phosphorylations of MAP kinases and NF-κB activation via IκBα degradation in macrophages. We conclude that britanin may have potential for the treatment of inflammatory diseases through the down-regulation of MAP kinases and NF-κB mediated activation of macrophages.

Abstract
Two stable high-performance liquid chromatography (HPLC) methods were developed that could quantitatively analyze 10 major marker compounds of Artemisia capillaris Thunb and could also distinguish among 'Injinho' and 'Myeon-injin' and 'Haninjin'--A. capillaris collected in autumn, A. capillaris collected in spring and A. iwayomogi, which can be misused as 'Injinho' in Korean herbal drug markets. The first HPLC method was a reversed-phase chromatography using a C18 column with an isocratic solvent system of phosphoric acid (0.05%) and acetonitrile at the flow rate of 1.0 mL/min, ultraviolet (UV) detection wavelength at 254 nm and column temperature at 40°C. Calibration and quantitation were made by using acetaminophen as an internal standard (I.S-A) and chlorogenic acid (1) was determined within 20 min. The second HPLC method was a reversed-phase chromatography using a C18 column with a gradient solvent system of phosphate buffer (0.015 M, pH 6) and acetonitrile at the flow rate of 1.0 mL/min, UV detection wavelength at 254 nm and column temperature at 40°C. Calibration and quantitation were made by using ethylparaben as an internal standard (I.S-B) and 3,5-di-O-caffeoylquinic acid (2), 3,4-di-O-caffeoylquinic acid (3), 4,5-di-O-caffeoylquinic acid (4), hyperoside (5), isoquercitrin (6), isorhamnetin 3-O-robinobioside (7), isorhamnetin-3-O-galactoside (8), isorhamnetin-3-O-glucoside (9) and scoparone (10) were determined within 60 min. Pattern recognition analysis of data from the 60 samples classified them clearly into three groups. These assay methods could be applied for QA/QC of A. capillaris and Artemisia iwayomogi.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The flowers of Inula japonica (Inulae Flos) have long been used in traditional medicine for the treatment of bronchitis, digestive disorders, and inflammation. However, the mechanisms underlying its anti-inflammatory effects remain yet to be elucidated. The objectives of this study were 1) to assess the anti-allergic activity of the ethanol extract of flowers of Inula japonica extract (IFE) in vivo, 2) to investigate the mechanism of its action on mast cells in vitro, and 3) to identify its major phytochemical compositions. MATERIALS AND METHODS The anti-allergic activity of IFE was evaluated using mouse bone marrow-derived mast cells (BMMCs) in vitro and a passive cutaneous anaphylaxis (PCA) animal model in vivo. The effects of IFE on mast cell activation were evaluated in terms of degranulation, eicosanoid generation, Ca(2+) influx, and immunoblotting of various signaling molecules. RESULTS IFE inhibited degranulation and the generation of eicosanoids (PGD(2) and LTC(4)) in stem cell factor (SCF)-stimulated BMMCs. Biochemical analysis of the SCF-mediated signaling pathways demonstrated that IFE inhibited the activation of multiple downstream signaling processes including mobilization of intracellular Ca(2+) and phosphorylation of the mitogen-activated protein kinases (MAPKs), PLCγ1, and cPLA(2) pathways. When administered orally, IFE attenuated the mast cell-mediated PCA reaction in IgE-sensitized mice. Its major phytochemical composition included three sesquiterpenes, 1-O-acetylbritannilactone, britanin and tomentosin. CONCLUSIONS This study suggests that IFE modulates eicosanoids generation and degranulation through the suppression of SCF-mediated signaling pathways that would be beneficial for the prevention of allergic inflammatory diseases. Anti-allergic activity of IFE may be in part attributed particularly to the presence of britanin and tomentosin as major components evidenced by a HPLC analysis.

Abstract
Phellodendri Cortex is the bark of the stems of Phellodendron amurense Ruprecht or P. chinense Schneider (Rutaceae), which is orginated from periderm. The internal transcribed spacer sequences of 20 originated plants and identified samples were analyzed. The result showed that the 99% of the base sequences of P. amurense were identical to that of P. chinense, but the differentiation of P. amurense and P. chinense was difficult. In addition, the ribulose-1, 5-bisphospate carboxylase large subunit (rbcL) intergenic spacer sequences of specific parts produced the same result. However, when the analysis was carried out by using the RAPD (randomly amplification polymorphism DNA) analysis method, which utilizes 48 randomly primers, it allowed us to confirm the polymorphism of P. amurense and P. chinense in 12 primers. A high-performance liquid chromatographic (HPLC) method was developed and validated for the simultaneous quantitation of berberine, palmatine and jatrorrhizine in a traditional herbal drug, Phellodendri Cortex. The HPLC method was applied successfully to the quantification of three constituents in the extract of twenty Phellodendri Cortex. The results indicated that the established HPLC and RAPD methods are suitable for the quantitative analysis and the quality control multi-simultaneous discrimination in Phellodendri Cortex.

Abstract
BACKGROUND Urticaria is the commonest cutaneous reaction caused by aspirin or other nonsteroidal anti-inflammatory drugs. The pathogenesis of aspirin-induced urticaria (AIU) is not fully understood, but appears to involve mast cell activation and neutrophil infiltration. OBJECTIVES To investigate the genetic contribution of interleukin (IL)-18, which can amplify acute inflammation by promoting mast cell activation, neutrophil migration and cytokine production, to the pathogenesis of AIU. METHODS A case-control association study was performed using 275 patients with AIU and 196 normal healthy controls in a Korean population. Two promoter polymorphisms of the IL18 gene (-607A/C and -137G/C) were genotyped using the primer extension method. The functional effect of the IL18 gene promoter polymorphism was investigated through in vitro studies including a luciferase reporter assay and electrophoretic mobility shift assays (EMSAs) and ex vivo studies involving neutrophil chemotaxis assays. RESULTS A significant association was detected between both AIU in general and the aspirin-intolerant acute urticaria (AIAU) phenotype and the IL18 promoter polymorphism -607A/C. Patients with AIAU showed higher frequencies of the C(-607) G(-137) haplotype, ht1 [CG], compared with controls (P=0·02). Moreover, ht1 [CG] showed a high transcript haplotype by the luciferase activity assay, and EMSAs identified a -607C allele-specific DNA-binding protein as CREB2. Neutrophil chemotactic activity was highest in subjects with AIU exhibiting the high transcript haplotype, ht1 [CG] (P=0·019). CONCLUSIONS The high transcript haplotype ht1 [CG] of the IL18 gene may contribute to the development of acute cutaneous inflammation sensitive to aspirin, leading to the clinical presentation of AIAU.

Abstract
A series of benzo-annulated rutaecarpines were prepared from anthranilic acid and 3-aminonaphthalene-2-carboxylic acid by Fischer indole synthesis as key reaction. Cytotoxicity was somewhat increased by the introduction of benzo-annulation, which was not directly related to the inhibitory activity against topoisomerases (topo) I and II. Benzo-annulation on ring A led to significant increase of inhibitory activity against topo II while annulations on ring E increased inhibitory activity against topo I.

Abstract
Background The flowers of Inula japonica (Inulae Flos) have long been used in traditional medicine for the treatment of inflammatory diseases. In the present study, we investigated the anti-inflammatory properties of Inulae Flos Extract (IFE). Methods The anti-inflammatory effects of IFE against nitric oxide (NO), PGE2, TNF-α, and IL-6 release, as well as NF-κB and MAP kinase activation were evaluated in RAW 264.7 cells. Results IFE inhibited the production of NO and the expression of inducible nitric oxide synthase (iNOS) in LPS-stimulated RAW264.7 cells. In addition, IFE reduced the release of pro-inflammatory cytokines, such as TNF-α and IL-6. Furthermore, IFE inhibited the NF-κB activation induced by LPS, which was associated with the abrogation of IκB-α degradation and subsequent decreases in nuclear p65 and p50 levels. Moreover, the phosphorylation of ERK, JNK, and p38 MAP kinases in LPS-stimulated RAW 264.7 cells was suppressed by IFE in a dose-dependent manner. Conclusion These results suggest that the anti-inflammation activities of IFE might be attributed to the inhibition of NO, iNOS and cytokine expression through the down-regulation of NF-κB activation via suppression of IκBα and MAP kinase phosphorylation in macrophages.

Abstract
AIM OF THE STUDY The aerial part of Saururus chinensis has been used in folk medicine to treat several inflammatory diseases in China and Korea. Previously, our group reported that anti-asthmatic activity of an ethanol extract of Saururus chinensis (ESC) might occur, in part, via the inhibition of prostaglandin D(2) (PGD(2)) and leukotriene C(4) (LTC(4)) production, and degranulation reaction in vitro, as well as through the down-regulation of interleukin (IL)-4 and eotaxin mRNA expression in an in vivo ovalbumin-sensitization animal model. However, the effects of Saururus chinensis on eicosanoid generation, as well as Th2 cytokines and eotaxin production in an in vivo asthma model, have not been fully investigated. Moreover, it has not been determined whether ESC can ameliorate airway inflammation in vivo. In the present study, we investigated the therapeutic activity of Saururus chinensis on ovalbumin (OVA)-sensitized airway inflammation and its major phytochemical compositions. MATERIALS AND METHODS Asthma was induced in BALB/c mice by ovalbumin-sensitization and inhalation. ESC (10-100 mg/kg) or dexamethasone (5 mg/kg), a positive control, was administered 7 times orally every 12 h from one day before the first challenge to 1 h before the second challenge. The recruitment of inflammatory cells and hyperplasia of goblet cells were evaluated by H&E and PAS staining. Levels of Th2 cytokines, eotaxin, PGD(2) and LTC(4) were measured to evaluate the anti-inflammatory activity of ESC in OVA-sensitized mice. Contents of major components were analyzed by HPLC using a reversed-phase C18 column. RESULTS ESC (10 mg/kg) suppressed allergic airway inflammation by inhibition of the production of IL-4 (P<0.001), IL-5 (P<0.05), IL-13 (P<0.001), eotaxin (P<0.001), PGE(2) (P<0.001), LTC(4) (P<0.001) in lung extract and IgE level (P<0.001) in the serum. In addition, ESC (50 mg/kg) reduced the infiltration of inflammatory cells and hyperplasia of goblet cells in the lung tissues. The anti-inflammatory effect of ESC was comparable to that of the positive control drug, dexamethasone. Its major phytochemical composition includes manassantin A, B and sauchinone. CONCLUSIONS These results suggest that ESC decreased inflammation and mucus secretion in the OVA-induced bronchial asthma model, and its anti-asthmatic activity may occur in part via the inhibition of Th2 cytokines and eotaxin protein expression, as well as through prostaglandin E(2) (PGE(2)) and leukotriene C(4) (LTC(4)) generation. This effects may be attributed particularly to the presence of manassantin A, B and sauchinone major component evidenced by a HPLC analysis.

Abstract
Previously, we reported that an ethanol extract of Ailanthus altissima has antiinflammatory activity in an ovalbumin (OVA)-sensitized murine asthmatic model. To determine the biological compounds from this plant, luteolin-7-O-glucoside (L7G) was isolated and its antiasthmatic activity was evaluated in an in vivo murine asthmatic model. L7G (10 to 100 mg/kg, per os (p.o.)) reduced the amount of eosinophil infiltration in bronchoalveolar lavage (BAL) fluid in a dose-dependent manner. In comparison, dexamethasone (5 mg/kg, p.o.), which was used as a positive control, also strongly inhibited the number of infiltrating eosinophils. L7G inhibited both the prostaglandin E(2) (PGE(2)) and serum immunoglobulin E level in BAL fluid in a dose-dependent manner. In addition, L7G inhibited the transcript profiles of interleukin (IL)-4, IL-5, and IL-13 mRNA expression levels in the murine asthma model, as determined using reverse transcription-polymerase chain reaction (RT-PCR). These results suggest that the antiasthmatic activity of L7G in OVA-induced lung inflammation may occur in part via the downregulation of T helper 2 cytokine transcripts as well as the inhibition of PGE(2) production.

Abstract
5-Methoxy-8-(2-hydroxy-3-buthoxy-3-methylbutyloxy)-psoralen (MP) is a medicinal herbal product isolated from Angelica dahurica that inhibits the cyclooxygenase-2 (COX-2)-dependent phase of prostaglandin D(2) (PGD(2)) generation in bone marrow-derived mast cells (IC(50), 23.5 microM). Western blotting with specific anti-COX-2 antibodies showed that the decrease in PGD(2) production was accompanied by a decrease in COX-2 protein levels. In addition, this compound consistently inhibited the production of leukotriene C(4) in a dose dependent manner, (IC(50), 2.5 microM). These results demonstrate that MP inhibits both cyclooxygenase-2 and 5-lipoxygenase activity. Furthermore, this compound also inhibited the degranulation reaction (IC(50), 4.1 microM). Therefore, this compound might provide a basis for novel anti-inflammatory drug development.

Abstract
Isoimperatorin (4-[(3-Methyl-2-butenyl)oxy]-7H-furo[3,2-g][1]benzopyran-7-one) is a medicinal herbal product that is isolated from the dried roots of Angelicae dahuricae. Isoimperatorin inhibits the cyclooxygenase-2 (COX-2) and COX-1-dependent phases of prostaglandin D2 (PGD2) generation in bone marrow-derived mast cells (BMMC) in a concentration-dependent manner, with IC50 values of 10.7 microM and 24 microM, respectively. However, this compound was not able to inhibit COX-1 and 2 protein expression in BMMC that were treated with concentrations of up to 50 microM, which indicates that isoimperatorin directly inhibits COX-2 activity. Furthermore, this compound consistently inhibited the production of leukotriene C4 (LTC4), as well as the degranulation reaction in BMMC, with an IC50 value of 5.7 microM and 9 microM, respectively, and these effects occurred in a dose dependent fashion. These results demonstrate that isoimperatorin has a dual cyclooxygenase-2 selective/5-lipoxygenase inhibitory activity, and therefore may provide the basis for novel anti-inflammatory drugs.

Abstract
To determine a possible role of glutathione (GSH) conjugation in 1,3-dibromopropane (1,3-DBP)-induced hepatotoxicity and immunotoxicity, female BALB/c mice were treated orally with 1,3-DBP. Based on the liquid chromatography/electrospray ionization-tandem mass spectrometry (LC/ESI-MS) analyses, two forms of S-bromopropyl GSH were observed at m/z 427.9 and 429.9 in the positive ESI spectrum with a retention time of 5.29 and 5.23 min, respectively. Following single treatment of mice with 150, 300 or 600 mg/kg 1,3-DBP for 12 hr, the amount of S-bromopropyl GSH was detected maximally in liver homogenates at 600 mg/kg 1,3-DBP. Hepatic GSH levels were significantly decreased by treatment with 1,3-DBP. In a time course study, production of S-bromopropyl GSH rose maximally 6 hr after treatment and decreased gradually thereafter. The liver weights were significantly increased by treatment with 600 mg/kg 1,3-DBP. When mice were treated orally with 600 mg/kg 1,3-DBP for 12 hr, the activities of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were increased by 365- and 83-fold. In addition, oral 1,3-DBP significantly suppressed the antibody response to a T-dependent antigen at 600 mg/kg 1,3-DBP. 1,3-DBP elevated hepatic levels of malondialdehyde and suppressed the activities of some hepatic enzymes involved in anti-oxidation. Taken together, the formation of GSH conjugate with 1,3-DBP may deplete cellular GSH and, subsequently, produce hepatotoxicity and immunotoxicity via damage to the cellular anti-oxidative system.

Abstract
This study investigated the protective effects of a group IIA secretory phospholipase A2 (sPLA2-IIA) inhibitor, ochnaflavone, on the progression of carbon tetrachloride (CCl4)-induced acute liver injury in rat liver microsomes in vitro. When rat liver was incubated at 37 degrees C in the presence of CCl4, the level of phosphatidylethanolamine (PE) degradation increased markedly compared with the control. The rat 14 kDa platelet PLA2 antibody, R377, suppressed the degradation of PE. Pretreating the microsome with ochnaflavone (2-16 microM) reduced the level of PE degradation in a dose dependent manner. In addition, p-bromophenacy bromide (p-BPB), which is a PLA2 inhibitor, also inhibited PE degradation. However, the inhibitory activity was weaker than that of ochnaflavone. Further investigation showed that ochnaflavone not only inhibited the purified rat platelet sPLA2 activity in a dose dependent manner with an IC50 value of 3.45 microM, when arachidonyl PE was used as a substrate, but also inhibited lipid peroxidation in a dose dependent manner with an IC50 value of 7.16 microM. This result suggests that ochnaflavone prevents the progression of CCl4-induced PE hydrolysis by inhibiting the endogenous sPLA2 activity.

Abstract
Ochnaflavone is a medicinal herbal product isolated from Lonicera japonica that inhibits cyclooxygenase-2 (COX-2) dependent phases of prostaglandin D2 (PGD2) generation in bone marrow-derived mast cells (BMMC) in a concentration-dependent manner with IC50 values of 0.6 microM. Western blotting probed with specific anti-COX-2 antibodies showed that the decrease in quantity of the PGD2 product was accompanied by a decrease in the COX-2 protein level. In addition, this compound consistently inhibited the production of leukotriene C4 (LTC4) in a dose dependent manner, with an IC50 value of 6.56 microM. These results demonstrate that ochnaflavone has a dual cyclooxygenase-2/5-lipoxygenase inhibitory activity. Furthermore, this compound strongly inhibited degranulation reaction in a dose dependent manner, with an IC50 value of 3.01 microM. Therefore, this compound might provide a basis for novel anti-inflammatory drugs.

Abstract
We have found experimentally that the shot noise of the tunneling current I through an undoped semiconductor superlattice is reduced with respect to the Poissonian noise value 2eI, and that the noise approaches 1/3 of that value in superlattices whose quantum wells are strongly coupled. On the other hand, when the coupling is weak or when a strong electric field is applied to the superlattice, the noise becomes Poissonian. Although our results are qualitatively consistent with existing theories for one-dimensional multibarrier structures, the theories cannot account for the dependence of the noise on superlattice parameters that we have observed.

Abstract
As an attempt to find bioactive medicinal herbs exerting anti-asthmatic activity, the effects of an ethanol extract from the parts of Saururus chinensis were evaluated in both in vitro and in vivo. The ethanol extract of S. chinensis (ESC) inhibited generation of the cyclooxygenase-2 (COX-2) dependent phases of prostaglandin D(2) in bone marrow-derived mast cells in a concentration-dependent manner with an IC(50) value of 14.3 microg/ml. ESC also inhibited leukotriene C(4) production with an IC(50) value of 0.3 microg/ml. This demonstrates that ESC has COX-2/5-lipoxygenase dual inhibitory activity. In addition, this compound inhibited degranulation reaction in a dose dependent manner, with an IC(50) value of 1.3 microg/ml. An ovalbumin induced mouse asthmatic animal model was used to determine its in vivo anti-asthmatic activity. The oral administration (50-200 mg/kg) of ESC reduced the number of infiltrated eosinophil in a bronchoalveolar lavage fluid. Furthermore, ESC (100 mg/kg) inhibited the eotaxin and IL-4 mRNA expression levels. These results suggest that the anti-asthmatic activity of S. chinensis might in part occur via the inhibition of eicosanoid generation, degranulation as well as the down regulation of IL-4 and eotaxin mRNA expression.

Abstract
Lipopolysaccharide (LPS)-stimulated macrophages produce large amounts of nitric oxide (NO) by inducible nitric oxide synthase (iNOS). This is an important mechanism in macrophage-induced septic shock and inflammation. In the present study, we tested a synthetic propenone compound, 1-furan-2-yl-3-pyridin-2-yl-propenone (FPP-3) for its ability to inhibit the production of tumor necrosis factor-alpha (TNF-alpha) and an inducible enzyme, iNOS, in the LPS-stimulated murine macrophage-like cell line, RAW264.7. FPP-3 consistently inhibited nitric oxide (NO) and TNF-alpha production in a dose dependent manner, with IC(50) values of 10.0 and 13.1 microM, respectively. Western blotting probed with specific anti-iNOS antibodies showed that the decrease in quantity of the NO product was accompanied by a decrease in the iNOS protein level. In cells transiently transfected with nuclear factor (NF)-kappaB promoter-luciferase reporter construct, this compound clearly inhibited the LPS-stimulated NF-kappaB activation. Moreover, this compound inhibited IkappaB-alpha degradation in a concentration and time-dependent manner. These results indicate that FPP-3 inhibits NO production via inhibition of degradation of IkappaB-alpha through NF-kappaB activation.

Abstract
Deoxypodophyllotoxin (Anthricin) is a medicinal herbal product isolated from Anthriscus sylvestris HOFFM. that inhibits cyclooxygenase-2 (COX-2) and COX-1-dependent phases of prostaglandin D(2) (PGD(2)) generation in bone marrow-derived mast cells (BMMC) in a concentration-dependent manner with IC(50) values of 1.89 microM and 65.3 microM, respectively. This study also found that this compound inhibited COX-1 and 2-dependent conversion of the exogenous arachidonic acid to PGD(2) in a dose-dependent manner with an IC(50) values of 0.01 microM and 12.1 microM, respectively using a COX enzyme assay kit. However, this compound did not inhibit COX-2 protein expression up to a concentration of 30 microM in the BMMC, indicating that deoxypodophyllotoxin directly inhibits COX-2 activity. Furthermore, this compound consistently inhibited the production of leukotriene C(4) (LTC(4)) in a dose dependent manner, with an IC(50) value of 0.37 microM. These results demonstrate that deoxypodophyllotoxin has a dual cyclooxygenase-2 selective/5-lipoxygenase inhibitory activity, and therefore this compound might provide a basis for novel anti-inflammatory drugs.

Abstract
Ginkgetin, a biflavone from Ginkgo biloba leaves, was previously reported to be a phospholipase A(2) inhibitor and this compound showed the potent antiarthritic activity in rat adjuvant-induced arthritis as well as analgesic activity. This investigation was carried out to find effects on cyclooxygenase-2 (COX-2) in vitro effect. Ginkgetin inhibits COX-2 dependent phases of prostaglandin D(2) (PGD(2)) generation in bone marrow-derived mast cells (BMMC) in a concentration-dependent manner with IC(50) values of 0.75 microM. Western blotting probed with specific anti-COX-2 antibodies showed that the decrease in quantity of the PGD(2) product was accompanied by a decrease in the COX-2 protein level. In addition, this compound consistently inhibited the production of leukotriene C(4) (LTC(4)) in a dose dependent manner, with an IC(50) value of 0.33 microM. These results demonstrate that ginkgetin has a dual cyclooxygenase-2/5-lipoxygenase inhibitory activity. Furthermore, this compound also inhibited degranulation reaction in a dose dependent manner, with an IC(50) value of 6.52 microM. Therefore, this compound might provide a basis for novel anti-inflammatory agents.

Abstract
This study examined the effect of astilbic acid (3beta,6beta-dihydroxyolean-12-en-27-oic acid), which is a herbal medicine isolated from Astilbe chinensis. Astilbic acid inhibited 5-lipoxygenase (5-LOX)-dependent leukotriene C4 (LTC4) generation in bone marrow-derived mast cells in a concentration-dependent manner with an IC50 value of 2.1 microM. In addition, astilbic acid was tested in a rat passive cutaneous anaphylaxis (PCA) reaction assay by administering 10 to 50 mg/kg i.p. Astilbic acid dose dependently inhibited the PCA reaction, which was activated by anti-dinitrophenyl (DNP) IgE. Furthermore, this compound inhibited mouse acetic acid-induced writhing (47-62% inhibition at 0.4-50 mg/kg) after being administered orally, while aspirin (200 mg/kg) showed 62% inhibition. These results suggest that astilbic acid may be beneficial in regulating various inflammatory processes.

Abstract
Skin hyperpigmentations such as melasma, freckles and senile lentigines can be subjectively treated by depigmenting agents. In our ongoing study to find melanogenesis inhibitors from natural sources, Piper longum L (fruits, Piperaceae) was discovered to have an inhibitory effect on alpha-melanocyte-stimulating hormone (alpha-MSH)-induced melanogenesis in melanoma B16 cells. Piperlonguminine has been identified as the melanogenesis inhibitor from P. longum by activity-guided extraction and isolation. The compound showed dose-dependent inhibitory effects with 85.1 +/- 4.9% inhibition at 25 microM, 62.1 +/- 6.1% at 12.5 microM, 36.4 +/- 4.6% at 6.3 microM and 18.4 +/- 5.1% at 3.1 microM on alpha-MSH-induced melanogenesis, showing an IC50 value of 9.6 microM. As a positive control, kojic acid exhibited an IC50 value of 44.6 microM on the melanogenesis. As to the mode of action, piperlonguminine showed an inhibitory effect on alpha-MSH-induced tyrosinase synthesis, documented by Western immunoblot analysis. However, piperlonguminine did not show an inhibitory effect on tyrosinase activity or a direct depigmenting effect of melanin.

Abstract
This study examined the effect of a podophyllotoxin derivative, deoxypodophyllotoxin (anthricin), which is a medicinal herb product isolated from Anthriscus sylvestris Hoffm. Deoxypodophyllotoxin was tested in a rat PCA (passive cutaneous anaphylaxis) assay by administering deoxypodophyllotoxin intraperitoneally (1.0 to 10 mg/kg, i.p.) and intravenously (0.25 to 1.0 mg/kg, i.v.). Deoxypodophyllotoxin dose-dependently inhibited the PCA reaction activated by anti-dinitrophenyl (DNP) IgE. The PCA inhibitory activity of deoxypodophyllotoxin was stronger than those of prednisolone and indomethacin, which were used as positive controls. These results suggest that deoxypodophyllotoxin may be beneficial in regulating the immediate-type allergic reaction.

Abstract
Nardostachin, which is an iridoid isolated from Patrinia saniculaefolia, was examined by assessing its effect on the production of tumor necrosis factor-alpha (TNF-alpha) and expression of 2 enzymes, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), in lipopolysaccharide (LPS)-stimulated Raw264.7 macrophages. This compound consistently inhibited the production of nitric oxide (NO) and TNF-alpha production in a dose-dependent manner, with respective IC(50) values of 12.3 and 16.2 microM. The decrease in quantity of NO products was accompanied by a decrease in the iNOS protein level, as assessed by Western blotting probed with specific anti-iNOS antibodies. In addition, this compound also reduced the COX-2 protein expression level and the attendant PGE(2) production in LPS-stimulated macrophages. These results suggest that nardostachin may be useful for inhibiting the production of inflammatory mediators such as TNF-alpha, NO and PGE(2) in inflammatory diseases.

Abstract
Further studies on the seeds of Annona cherimolia have led to the isolation of two pairs of Annonaceous acetogenins, a mixture of epimers of annomolon A (1) and 34-epi-annomolon A (1'), and a mixture of epimers of annomolon B (2) and 34-epi-annomolon B (2'), containing a rare gamma-hydroxymethyl-gamma-lactone moiety and a carbonyl group. Their structures were elucidated on the basis of spectroscopic and chemical methods, and their absolute stereochemistry was solved by preparing their respective per-Mosher ester derivatives. These acetogenins showed substantial cytotoxicity, comparable to that of adriamycin, against a human pancreatic tumor cell line (MIA PaCa-2).

Abstract
Patridoids I, II and IIA, are new iridoids isolated from the whole plants of Patrinia saniculaefolia. These compounds were examined by assessing their effects on the production of tumor necrosis factor-alpha (TNF-alpha) as well as by investigating the expression of two enzymes, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), in the lipopolysaccharide (LPS)-stimulated murine macrophage-like cell line, Raw 264.7. Among them, patridoid II consistently inhibited nitric oxide (NO) and TNF-alpha production in a dose-dependent manner, with IC (50) values of 14.1 and 17.6 microM, respectively. Western Blotting probed with specific anti-iNOS antibodies showed that the decrease in the quantity of the NO product was accompanied by a decrease in the iNOS protein level. However, all three patridoids did not affect the COX-2 protein expression level in the LPS-stimulated macrophages. In addition, the C-5 isomer of patridoid II, patridoid I, only slightly affected the production of NO. Moreover, the C-3 isomer of patridoid II, patridoid IIA, did not inhibit proinflammatory cytokines and NO production. These results suggest that the orientations of the C-3 and C-5 methoxy groups in the patridoids have a significant role in the expression of their biological activity.
