Maackiain is a novel antiallergic compound that suppresses transcriptional upregulation of the histamine H1 receptor and interleukin-4 genes.,
Pharmacology Research & Perspectives, Vol.3, No.5, e00166, 2015.- (要約)
- Kujin contains antiallergic compounds that inhibit upregulation of histamine H1 receptor (H1R) and interleukin (IL)-4 gene expression. However, the underlying mechanism remains unknown. We sought to identify a Kujin-derived antiallergic compound and investigate its mechanism of action. The H1R and IL-4 mRNA levels were determined by real-time quantitative RT-PCR. To investigate the effects of maackiain in vivo, toluene-2,4-diisocyanate (TDI)-sensitized rats were used as a nasal hypersensitivity animal model. We identified (-)-maackiain as the responsible component. Synthetic maackiain showed stereoselectivity for the suppression of IL-4 gene expression but not for H1R gene expression, suggesting distinct target proteins for transcriptional signaling. (-)-Maackiain inhibited of PKCδ translocation to the Golgi and phosphorylation of Tyr(311) on PKCδ, which led to the suppression of H1R gene transcription. However, (-)-maackiain did not show any antioxidant activity or inhibition of PKCδ enzymatic activity per se. Pretreatment with maackiain alleviated nasal symptoms and suppressed TDI-induced upregulations of H1R and IL-4 gene expressions in TDI-sensitized rats. These data suggest that (-)-maackiain is a novel antiallergic compound that alleviates nasal symptoms in TDI-sensitized allergy model rats through the inhibition of H1R and IL-4 gene expression. The molecular mechanism underlying its suppressive effect for H1R gene expression is mediated by the inhibition of PKCδ activation.

Coleifolides A and B, Two New Sesterterpenoids from the Aerial Parts of Scutellaria coleifolia H.Lév.,
Chemistry & Biodiversity, Vol.12, No.8, 1200-1207, 2015.- (要約)
- Coleifolides A and B (1 and 2), two new sesterterpenoids with a -methyl-,-unsaturated--lactone moiety, were isolated from the aerial parts of Scutellaria coleifolia H.Lév. (Lamiaceae), together with three known compounds. Their structures were elucidated by NMR and MS examinations. Coleifolides A and B were concluded to be partially racemic compounds by the HPLC analysis using a chiral column or introduction of chiral derivatizing agents. The absolute configuration of the major isomer was determined by analyses of the CD spectrum as well as NMR data of (R)- and (S)-2-NMA derivatives. Coleifolides A and B are structurally similar to manoalide derivatives, previously isolated from marine sponges, and appear to be the first examples of this type of compounds being isolated from higher plants.

Prenylated Flavonoids from the Stems and Leaves of Desmodium caudatum and Evaluation of Their Inhibitory Activity against the Film-Forming Growth of Zygosaccharomyces rouxii F51.,
Journal of Agricultural and Food Chemistry, Vol.62, No.27, 6345-6353, 2014.- (要約)
- In order to provide scientific evidence for the relationship between the traditional usage, stems and leaves of Desmodium caudatum being used for protecting miso from spoilage, and its Japanese name (miso-naoshi), phytochemical study on the stems and leaves of this plant was carried out. Seven new prenylated flavonoids (1-3, 15-18), together with 19 known compounds (4-14, 19-26), were isolated, and the structures of new compounds were elucidated by extensive spectroscopic analyses. The minimum inhibitory concentrations (MICs) of 28 flavonoids, including 17 compounds (1, 2, 4, 5, 7-14, 20-22, 24, 25) isolated in this study and 11 flavonoids (27-37) previously isolated from the roots of this plant, against the film-forming yeast of Zygosaccharomyces rouxii F51 were determined. Fifteen compounds (2, 4, 5, 11, 12, 14, 21, 22, 25, 27, 28, 32-35) inhibited the film-forming growth of Z. rouxii F51 (MIC values, 7.8-62.5 g/mL), among which 2'',2''-dimethylpyran-(5'',6'':7,8)-5,2'-dihydroxy-4'-methoxy-(2R,3R)-dihydroflavonol (11) demonstrated potent inhibitory activity with an MIC value of 7.8 g/mL.

Triterpenoids from the fruits of Azadirachta indica (Meliaceae).,
Fitoterapia, Vol.92, 200-205, 2014.- (要約)
- Four new triterpenoids, indicalilacols A-D (1-4), were isolated from the MeOH extract of the fruits of Azadirachta indica, including a new 19(109)abeo-tirucallane derivative, two new tirucallane-type triterpenoids, and a new euphane-type triterpenoid, along with three known tirucallane-type triterpenoids. Their structures were elucidated on the basis of spectroscopic analyses. The absolute configuration of 2 was elucidated by the chemical conversion of 2 into 21-oxo-melianodiol 24,25-acetonide. Compounds 2, 6-8 exhibited moderate cytotoxicity against three human cancer cell lines, including multidrug-resistant (MDR) cancer cells (KB-C2). Although compound 5 was not cytotoxic against any of the tested cancer cell lines, 5 showed cytotoxicity against KB-C2 cells in the presence of 2.5 M colchicine, suggesting that 5 might have an MDR-reversal effect.

Structural elucidation and biological fate of two glucuronyl metabolites of pelargonidin 3-O--D-glucopyranoside in rats.,
Journal of Agricultural and Food Chemistry, Vol.61, No.3, 569-578, 2013.- (要約)
- A high proportion of pelargonidin 3-O--D-glucopyranoside (Pg3G) is metabolized to glucuronides and excreted in mammal urine after ingestion of strawberry fruit, suggesting that these metabolites play important functional roles in vivo. The aim of the present study was to elucidate the structures and determine the biological fate of the two dominant metabolites of Pg3G in rats to enable an accurate discussion of the biological properties of anthocyanins. Authentic Pg3G was orally administered to rats. One pelargonidin monoglucuronide and three Pg3G-monoglucuronides (glucuronides of the glucoside) were identified together with intact Pg3G in both blood plasma and urine samples. The structures of the two dominant metabolites were elucidated as pelargonidin 3-O--D-glucuronide (Pg3GlcA) and pelargonidin 3-O--D-glucuronyl-(12)--D-glucoside by means of (1)H and (13)C nuclear magnetic resonance spectroscopy and heteronuclear multiple-bond connective spectroscopy. The bioavailability of Pg3G in its intact form was 0.31% of the orally administered dose, and 0.65% was absorbed in the Pg3GlcA form.

Quantification of phosphatidic acid in foodstuffs using TLC-imaging technique,
Journal of Agricultural and Food Chemistry, Vol.60, No.16, 4156-4161, 2012.- (要約)
- Apical application of lysophosphatidic acid (LPA), a growth-factor-like phospholipid, was shown to prevent or restore gastrointestinal (GI) disorders, such as diarrhea and stomach ulcer, in experimental animals. Because LPA is formed from phosphatidic acid (PA) by the activity of digestive phospholipase A(2), PA is a potential component for dietary treatment of such GI disorders. Here, we quantified PA contained in 38 foodstuffs and 3 herbs by a thin-layer-chromatography-imaging technique. Vegetables belonging to Brassicaceae, such as cabbage leaves (700 nmol/g of wet weight) and Japanese radish leaves (570 nmol/g), contained higher amounts of PA than other foodstuffs. Amounts of PA in fruits, cereals, and starchy root vegetables were below 300 nmol/g. Animal foodstuffs contained low amounts of PA (<60 nmol/g). Interestingly, leaves of Mallotus japonicas, a Japanese edible herb used for treatment of stomach ulcer, had the highest PA (1410 nmol/g) among those examined. The data shown here will be useful for the development of dietary treatment for a damaged GI tract.

In cytotoxicity assays against three human cancer cell lines, including a multi-drug resistant cancer cell line (KB-C2), compounds 1, 2 and 5 demonstrated significantly enhanced cytotoxicity against KB-C2 cells in the presence of 2.5 μM colchicine, as compared with those in the absence of colchicine. This result suggested that these triterpenes might show some MDR-reversing effects.

Consultation clinics for complementary and alternative medicine at Japanese university hospitals: An analysis at Tokushima University Hospital,
Experimental and Therapeutic Medicine, Vol.1, No.3, 481-483, 2010.- (要約)
- Here, we report on a Consultation Clinic for Complementary and Alternative Medicine (CAM) which we established at Tokushima University Hospital in July of 2007 with the aim of providing person-to-person information on CAM, though not CAM therapy itself. In December of 2008, we received 55 applications for consultation, 37% concerning health foods, 37% Japanese herbal medicine (Kampo), and 26% various other topics. The consultants (nutritionists and pharmacists) communicated individually with 38 applicants; malignancies (26%) and cardiovascular disease (24%) were the main underlying concerns. To promote the quality of consultation, data was collected by means of focus group interviews concerning the perspective of the consultants. Safe and effective use of CAM requires a network of communication linking individuals, consultation teams, physicians, primary care institutions and university hospitals. To advance this goal, we plan to broaden the efforts described herein. Our findings indicate that the specific role of the consultation clinic in promoting the scientific use of CAM merits further study.

Papyriferic Acid Derivatives as Reversal Agents of Multidrug Resistance in Cancer Cells.,
Bioorganic & Medicinal Chemistry, Vol.18, No.8, 2964-2975, 2010.- (要約)
- Forty-one derivatives of papyriferic acid were prepared based on our previous finding that methyl papyriferate (3) showed potent reversing effect on cytotoxicity of colchicine against multidrug resistance (MDR) human cancer cells (KB-C2), and evaluated for their cytotoxicity and effect on reversing P-gp-mediated MDR against KB-C2 cells. 3-O-(Morpholino-beta-oxopropanoyl)-12beta-acetoxy-3alpha,25-dihydroxy-(20S,24R)-epoxydammarane (37) significantly increased the sensitivity of colchicine against KB-C2 cells by 185-fold at 5microg/mL (7.4microM), and the cytotoxicity of colchicine was recovered to nearly that of sensitive (KB) cells. The other several new amide derivatives also exhibited potent reversal activity comparable to or more potent than methyl papyriferate and verapamil.

Tomoenones A-H, cytotoxic phloroglucinol derivatives from Hypericum ascyron,
Phytochemistry, Vol.69, No.11, 2225-2230, 2008.- (要約)
- Phloroglucinol derivatives tomoeones A-H (1-8) and three known compounds were isolated from leaves of Hypericum ascyron. Their structures were established based on spectroscopic analyses. They are all acylphloroglucinol derivatives possessing a spiro skeleton with geminal isoprenyl groups and a monoterpene moiety, and they are stereoisomers to each other at C-4 and C-13. They appear to be a class of phloroglucinol derivatives. Cytotoxicities of the isolated phloroglucinol derivatives against human tumor cell lines, including multidrug-resistant (MDR) cancer cell lines, were evaluated. Tomoeone F (6) demonstrated significant cytotoxicity against KB cells with an IC50 value of 6.2 microM. Compound 6 was also cytotoxic against MDR cancer cell lines (KB-C2 and K562/Adr), which was more potent than doxorubicin.

Effect of Triterpenoids from the Floral Spikes of Betula platyphylla var. japonica on Glycoprotein Function,
Planta Medica, Vol.73, No.15, 1558-1562, 2007.- (要約)
- One of the major causes of multidrug resistance (MDR) in cancer cells is over-expression of P-glycoprotein (P-gp). We studied the effects of 20 triterpenes isolated from the floral spikes of Betula platyphylla var. japonica ( B. platyphylla) on P-gp function based on our previous finding that some of them showed MDR reversing effects. We evaluated accumulations and effluxes of rhodamine 123 as a P-gp substrate with P-gp over-expressing KB-C2 cells. Among the 20 triterpenes, compounds 3, 4, 8, 9, 13, 15, and 20 increased rhodamine 123 accumulations in KB-C2 cells, and three ( 8, 13, and 20) of them also inhibited efflux of rhodamine 123 out of cells. In addition, compounds 13 and 20 showed a weak inhibitory activity of P-gp ATPase. These results suggested that MDR reversing effects of compounds 13 and 20 are partly involved in inhibition of P-gp ATPase.

Triterpenoids from the Floral Spikes of Betula platyphylla var. japonica and Their Reversing Activity against Multidrug-Resistant Cancer Cells,
Journal of Natural Products, Vol.70, No.4, 623-627, 2007.- (要約)
- Four new triterpenes, together with 16 known triterpenes, were isolated from the floral spikes of Betula platyphylla var. japonica in a search for compounds capable of reversing multidrug resistance in cancer cells. The structures of the new triterpenes were elucidated as 3,4-seco-olean-4(23),13(18)-dien-3-oic acid (1), 3,4-seco-urs-4(23),20(30)-dien-3-oic acid (2), 3-O-methylmalonylepiocotillol II (6), and 3-O-methylmalonylcabraleahydroxylactone (16) by spectroscopic examination. The cytotoxicity of the isolated triterpenes against human cancer cell lines as well as multidrug-resistant cancer cell lines was evaluated. Most of the isolated triterpenes showed very weak cellular toxicities. Although no discernible differences were found in the cytotoxicities for the tested compounds against sensitive and resistant cell lines, the cytotoxicities for several triterpenes against multidrug-resistant cancer cell lines (KB-C2 or K562/Adr) were enhanced in the presence of nontoxic concentrations of colchicine or doxorubicin. Compound 10 reversed the cytotoxicity of colchicine against KB-C2 cells at 8.1 microM and showed comparable potency to 5 microM verapamil.

Tripfordines A-C, Sesquiterpene Pyridine Alkaloids from Tripterygium wilfordii, and Structure Anti-HIV Activity Relationships of Tripterygium Alkaloids,
Journal of Natural Products, Vol.69, No.9, 1271-1274, 2006.- (要約)
- Three new sesquiterpene pyridine alkaloids, tripfordines A-C (1-3), were isolated from an ethanolic extract of the roots of Tripterygium wilfordii, along with eight known pyridine alkaloids, and tested for in vitro cytotoxic and anti-HIV activity. The structures of the new compounds were established on the basis of spectroscopic data interpretation. Anti-HIV structure-activity relationships (SAR) for this compound type are proposed on the basis of the screening results from the newly isolated compounds and prior data of known sesquiterpene pyridine alkaloids. The position of a carboxyalkyl chain on the pyridine moiety was not critical since both 2'- and 4'-substituted compounds exhibited high anti-HIV activity (EC(50) 0.1 microg/mL). In contrast, a hydroxy group at C-8' (carboxypropyl side chain) or C-9' (carboxybutyl side chain) was found to affect anti-HIV activity.

Antibacterial and Antioxidant Activities of Quercetin Oxidation Products from Yellow Onion (Alliu cepa) Skin,
Journal of Agricultural and Food Chemistry, Vol.54, No.10, 3551-3357, 2006.- (要約)
- Four new quercetin-derived oxidation products (1-4) and lunularin-4-O-beta-D-glucoside (5) were isolated from a water extract of onion (Allium cepa) skin, together with 17 other known compounds. Antibacterial assays for the isolated compounds showed that 2-(3,4-dihydroxyphenyl)-4,6-dihydroxy-2-methoxybenzofuran-3-one (1) presented selective activity against Helicobacter pylori strains and 3-(quercetin-8-yl)-2,3-epoxyflavanone (4) showed antibacterial activity against MRSA and H. pylori strains at the same time that it increased susceptibility of MRSA to beta-lactams. Evaluation of antioxidant activity against DPPH for the isolated compounds showed that the new derivative compounds (1-4) and 2,5,7,3',4'-pentahydroxy-3,4-flavandione (6) are more active than quercetin.

Alkyl Gallates, Intensifiers of ß-Lactam Susceptibility in Methicillin-Resistant Staphylococcus aureus,
Antimicrobial Agents and Chemotherapy, Vol.49, No.2, 549-555, 2005.- (要約)
- We found that ethyl gallate purified from a dried pod of tara (Caesalpinia spinosa) intensified beta-lactam susceptibility in methicillin-resistant and methicillin-sensitive strains of Staphylococcus aureus (MRSA and MSSA strains, respectively). This compound and several known alkyl gallates were tested with MRSA and MSSA strains to gain new insights into their structural functions in relation to antimicrobial and beta-lactam susceptibility-intensifying activities. The maximum activity of alkyl gallates against MRSA and MSSA strains occurred at 1-nonyl and 1-decyl gallate, with an MIC at which 90% of the isolates tested were inhibited of 15.6 microg/ml. At concentrations lower than the MIC, alkyl gallates synergistically elevated the susceptibility of MRSA and MSSA strains to beta-lactam antibiotics. Such a synergistic activity of the alkyl gallates appears to be specific for beta-lactam antibiotics, because no significant changes were observed in the MICs of other classes of antibiotics examined in this study. The length of the alkyl chain was also associated with the modifying activity of the alkyl gallates, and the optimum length was C5 to C6. The present work clearly demonstrates that the length of the alkyl chain has a key role in the elevation of susceptibility to beta-lactam antibiotics.

Effects of triterpene saponins from Astragalus species on in vitro cytokine release,
Journal of Ethnopharmacology, Vol.96, No.1-2, 71-77, 2005.- (要約)
- Roots of Astragalus species are used to treat leukemia and for wound healing in Turkish folk medicine. In order to evaluate this information, the effect of 13 cycloartane- and 1 oleanan-type triterpene saponins isolated from Turkish species (Astragalus brachypterus, Astragalus cephalotes, Astragalus microcephalus, and Astragalus trojanus), as well as methanol extracts from the roots of three Astragalus species (Astragalus cephalotes, Astragalus oleifolius and Astragalus trojanus) were studied. Cytokine concentrations of interleukins IL-1beta, IL-8 and TNF-alpha after bacterial lipopolysaccharide (LPS) and IL-2, IL-4 and INF-gamma after phorbolacetate (PHA) stimulation were determined using commercial enzyme-linked immunosorbent assay (ELISA) kits. All triterpene saponins tested in the present study showed a prominent IL-2 inducing activity between 35.9% and 139.6%. Among the extracts the highest score was obtained for Astragalus oleifolius (141.2%). Glycosides of 20,24-epoxy and 20,25-epoxy cycloartanes showed higher IL-2 inducing activity than those of acyclic-cycloartane derivatives as well as aglycone of 20,24-epoxy cycloartanes, cycloastrogenol. Especially the activity of Astragaloside VII, a tridesmosidic glycoside of cycloastrogenol, was the most remarkable. The oleanan-type triterpene saponin also showed a prominent IL-2 inducing activity. IL-2 is a cytokine produced by activated T cells, which has shown powerful immunostimulatory and antineoplastic properties. Accordingly, the IL-2 inducing activity of the triterpene saponins might be the mechanism involved in order to explain the immunomodulatory and anticancer effects of Astragalus species.

Novel antioxidants isolated from plants of the genera Ferula, Inula, Prangos and Rheum collected in Uzbekistan,
Phytomedicine, Vol.11, No.7-8, 645-651, 2004.- (要約)
- We examined the effects of 48 compounds isolated from Ferula pallida, F. penninervis, Inula macrophylla, Prangos pabularia, P. tschimganica and Rheum maximowiczii collected in Uzbekistan on ADP/Fe2+-induced lipid peroxidation of egg yolk phosphatidylcholine liposomes. Of those compounds, 23 inhibited ADP/Fe2+-induced lipid peroxidation and nine showed especially strong inhibition of lipid peroxidation. Most compounds that inhibited peroxidation scavenged the 1,1'-diphenyl-2-picrylhydrazyl (DPPH) radical, indicating that the inhibition was due to radical scavenging. However, some compounds did not scavenge DPPH but inhibited lipid peroxidation significantly, suggesting that their inhibitory effect was not due to radical scavenging but to some other mechanism, such as prevention of Fe2+ function. Thus, we found various new antioxidants, some of which had a unique mechanism of action, in Ferula, Inula, Prangos and Rheum plants collected in Uzbekistan as seeds used in medicine.

Apoptosis Induction in HL-60 Cells and Inhibition of Topoisomerase II by Triterpene Celastrol,
Bioscience, Biotechnology, and Biochemistry, Vol.67, No.9, 1883-1887, 2003.- (要約)
- Celastrol, which is a triterpene purified from Celastraceae plants, has anticancer and anti-inflammatory activities. In this study we investigated to clarify whether celastrol can induce apoptosis in a human leukemia HL-60 model system. Celastrol was found to induce apoptosis, and the rank order of the potency of celastrol and its derivatives to induce internucleosomal DNA fragmentation was found to be celastrol>cela-H>the other derivatives=vehicle control. Many anticancer agents are known to possess the ability to inhibit topoisomerase II, so the inhibitory activities of celastrol and its derivatives on topoisomerase II were also explored. The rank order of the inhibitory activity was found to be celastrol>etoposide>cela-H, indicating that the apoptosis-inducing activities of cela derivatives correspond to their inhibitory activities on topoisomerase II. These data suggested that celastrol may cause its effects such as anticancer activity by the mechanism of apoptosis along with topoisomerase II inhibition.

Isolation and characterization of free radical scavenging flavonoid glycosides from the flowers of Spartium junceum by activity-guided fractionation,
Journal of Ethnopharmacology, Vol.73, No.3, 471-478, 2000.- (要約)
- Spartium junceum L. (Fabaceae) flowers are used for the treatment of peptic ulcers in Turkish folk medicine. The possible superoxide dismutase-like activity of the extracts, fractions and constituents obtained through activity-guided fractionation were studied by using in vitro electron spin resonance spectrometry, in order to explain the role of antioxidant principles in the potent antiulcerogenic activity of the extract. Despite the fact that the triterpene, spartitrioside, which was previously reported as the active antiulcerogenic constituent of the flowers was found almost inactive, the flavonoid-rich fractions showed potent antioxidant activity. Five flavonoid glycosides bearing catechol structure in ring B were isolated from the butanol extract and their structures were elucidated using 1H- and 13C-NMR techniques as isoquercitrin (quercetin 3beta-glucoside) (1,); luteolin 4'beta-glucoside (2); quercetin 3, 4'-diglucoside (3); azaleatin 3beta-glucoside (quercetin 5-methylether 3beta-glucoside) (4), quercetin 4'beta-glucoside (5). Flavonoids (2) and (4) showed the highest in vitro antioxidant activity with 22.59 and 19.08 U/ml, respectively.

Anti-ulcerogenic effects of Spartium junceum flowers on in vivo test models in rats,
Journal of Ethnopharmacology, Vol.70, No.3, 219-226, 2000.- (要約)
- Flowers of Spartium junceum L. (Fabaceae) are used for the treatment of gastric ulcers in Turkish folk medicine. Through bioassay-guided fractionation using chemical and chromatographical means and water immersion and restraint-induced stress ulcer model in rats, a saponin fraction was determined as the potent anti-ulcerogenic ingredient. The active fraction was also highly effective in preventing ethanol- and pyloric ligation-induced gastric lesions as well as inhibiting gastric secretion volume, gastric pH and titratable acidity, but did not affect the hexosamine content of the gastric mucosa. A novel oleanen-type triterpenic saponin, named as spartitrioside, was isolated as the active principle by using chromatographical separation techniques.

Effects of the Turkish subspecies of Viscum album on macrophage-derived cytokines,
Journal of Ethnopharmacology, Vol.61, No.3, 195-200, 1998.- (要約)
- Viscum album L. herbs are used for the treatment of various diseases. Apart from their immunostimulatory, antitumor, and hypotension inducing activities, anti-inflammatory effects has also been recorded in the literature. Since the immunostimulatory activity of mistletoe is mainly attributed to a stimulation of the mononuclear phagocytic system and to an induction of inflammation by macrophage-derived cytokines, utilization based on anti-inflammatory activity seems in contrast with its use as immunostimulant. The inhibitory effects of 80% ethanol extracts and subfractions obtained by petroleum ether, diethylether, ethylacetate and n-butanol from three Turkish subspecies of V. album L. (ssp. album, ssp. abietis, ssp. austriacum) against interleukins (IL-1alpha and IL-1beta) and tumor necrosis factor-alpha were studied. Ethanolic (80%) extracts of all three subspecies exhibited almost no significant inhibitory activity on the proinflammatory cytokines, at least in the concentrations applied in this study. In contrast, they induce a concentration dependent stimulation of these cytokines. On the other hand, moderate to weak, dose dependent inhibitory effects were observed on fractionation, which may be attributed to the existence of less polar components with anti-inflammatory activity. Based on our results, it was concluded that the utilization of ethanol extracts for anti-inflammatory purposes would not be beneficial probably due to the partial extraction of the low-molecular-weight polypeptides, i.e. viscotoxins, which induce an inflammatory response. Moreover, for anti-inflammatory effects, extracts of Viscum album ssp. austriacum may be preferred, since higher inhibitory ratios were obtained against inflammatory cytokines than with the other two subspecies.

Benzoquinones Inhibit the Expression of Inducible Nitric Oxide Synthase Gene`,
Biochemical and Biophysical Research Communications, Vol.239, No.2, 367-371, 1997.- (要約)
- Benzoquinones inhibited the production of NO induced by LPS and gamma-IFN in C6 glia cells. The mechanistic studies showed that benzoquinones inhibited the expression of iNOS mRNA through inactivation of NF kappa B. Benzoquinones may be a useful candidate for the development of a drug to treat disease due to iNOS gene over-expression.

Suppression of Inducible Nitric Oxide Synthase mRNA Expression by Tryptoquinone A,
Biochemical and Biophysical Research Communications, Vol.224, No.2, 579-585, 1996.- (要約)
- Triptoquinone A (TQA), which is an anti-inflammatory constituent in plants, was studied for its suppressive effect on nitric oxide production by LPS. TQA significantly suppressed smooth muscle relaxation and increase in cyclic GMP levels by nitric oxide (NO) in an L-arginine-induced relaxation experiment. The mechanistic studies showed that TQA did not directly inhibit NO radicals and inducible nitric oxide synthase (iNOS) enzyme but suppressed IL-1 beta and iNOS mRNA expression by LPS. The suppression level of iNOS gene expression by TQA was comparable to that by dexamethasone. TQA may be a useful candidate for the development of a drug as a potent inhibitor of iNOS gene over-expression.
