With the current worldwide pandemic of COVID-19, there is an urgent need to develop effective treatment and prevention methods against SARS-CoV-2 infection. We have previously reported that the proanthocyanidin (PAC) fraction in blueberry (BB) leaves has strong antiviral activity against hepatitis C virus (HCV) and human T-lymphocytic leukemia virus type 1 (HTLV-1). In this study, we used Kunisato 35 Gou (K35) derived from the rabbit eye blueberry (Vaccinium virgatum Aiton), which has a high PAC content in the leaves and stems. The mean of polymerization (mDP) of PAC in K35 was the highest of 7.88 in Fraction 8 (Fr8) from the stems and 12.28 of Fraction 7 (Fr7) in the leaves. The composition of BB-PAC in K35 is that most are B-type bonds with a small number of A-type bonds and cinchonain I as extension units. A strong antiviral effect was observed in Fr7, with a high polymerized PAC content in both the leaves and stems. Furthermore, when we examined the difference in the action of BB-PAC before and after SARS-CoV-2 infection, we found a stronger inhibitory effect in the pre-infection period. Moreover, BB-PAC Fr7 inhibited the activity of angiotensin II converting enzyme (ACE2), although no effect was observed in a neutralization test of pseudotyped SARS-CoV-2. The viral chymotrypsin-like cysteine protease (3CLpro) of SARS-CoV-2 was also inhibited by BB-PAC Fr7 in leaves and stems. These results indicate that BB-PAC has at least two different inhibitory effects, and that it is effective in suppressing SARS-CoV-2 infection regardless of the time of infection.

Two new angular-type pyranocoumarins, namely hyuganin G (1) and hyuganin H (2), were isolated from an ethyl acetate extract of the aerial parts of Angelica furcijuga, together with three known angular-type pyranocoumarins, isoepoxypteryxin (3), isopteryxin (4), and hyuganin E (5). Assignment of the 1H and 13C NMR data of 1 and 2 were achieved via analysis of the DEPT, HMQC, and HMBC spectra. The absolute configurations of 1 and 2 were determined by semi-synthesis from 3.

In this study, a new extractant has been developed for mutual separation of Cu(II) / Fe(III) and Cd(II) / Zn(II) from acidic media. These metals are mainly discharged from smelting and refining processes of copper, zinc, and lead. However, the mutual separation of these metals is difficult due to their similar chemical properties. In order to separate these metals, isooctyl thioglycolate (IOTG) which has carbonyl and thiol groups was proposed as a new extractant. Furthermore, 1-dodecanethiol (DOTH) with only a thiol group was used for comparison. We found that IOTG in toluene can selectively separate Cu(II) over Fe(III) and Cd(II) over Zn(II). We paid attention to the selective extraction of Cd(II) with high toxicity and examined the extraction equilibria of Zn(II) and Cd(II) in detail. These extraction equilibria are determined by the conventional slope analysis method from 1 M aqueous ammonium nitrate solution. It was found that the selective extraction of Cd(II) over Zn(II) is due to the formation of the binuclear Cd(II) complexes while Zn(II) is extracted as the mononuclear complex. Furthermore, the stripping of Cd(II) and Zn(II) extracted into the organic phase was achieved using appropriate concentrations of various acids.

The leaves and branches of rabbiteye blueberry are rich in proanthocyanidins, which are thought to have different physiological activities depending on their structure and degree of polymerization. In this study, we analyzed the constituents of the leaves and branches of rabbiteye blueberry to determine the seasonal variations in polyphenol and proanthocyanidin (PAC) contents as well as their mean degrees of polymerization (mDP). Total PAC content was determined using two methods: The p-dimethylaminocinnamaldehyde (DMACA) method, which measures monomeric PAC, showed an increase from spring to summer in both leaves and branches. On the other hand, using the butanol/HCl method, which measures only polymerized PAC, the PAC content of leaves increased from spring to summer but those of branches remained low throughout the year, showing no significant increase or decrease. Furthermore, analysis of the mDP of PAC showed increases from spring to summer in the leaves of ‘Kunisato 35 gou’. Although the highest value (8.0) was observed in October, values around 4 remained throughout the year in the branches. Since differences in polymerization degree affect absorption in the body and physiological properties such as antioxidant capacity, selecting the appropriate harvest time and plant organs for each purpose is expected to ensure the quality of processed blueberry foods.

Phytanic acid is one of the branched-chain fatty acids in the human diet. Humans incorporate it into their bodies through the ingestion of ruminant meat and milk since these animal products contain the 3RS, 7R, 11R-isomer, as naturally occurring phytanic acid (nPA). Although phytanic acid has been reported to have health-promoting effects such as immunomodulatory effects, these findings were obtained mostly from in vitro cell-based experiments. In this study, the in vivo anti-inflammatory effects of nPA were investigated using a mouse model of dextran sulfate sodium (DSS)-induced colitis. Mice were fed diets containing 0%, 0.05%, or 0.1% nPA for 4 weeks. During the fourth week, acute colitis was induced by administration of a 3% DSS solution. The intake of 0.05% and 0.1% nPA inhibited DSS-induced body weight loss in mice, and showed improvement of histopathological changes in colon epithelium. nPA also inhibited the production of proinflammatory cytokines, especially macrophage-related cytokines such as interleukin-1β in the colon. These results suggest that nPA exerts anti-inflammatory effects under in vivo physiological conditions. Practical application: There is a growing demand for fatty acids possessing distinct nutritional and physical characteristics in the realms of health, nutrition, and food-related applications. The present study demonstrated that a branched-chain fatty acid, phytanic acid, exerts anti-inflammatory activity under not only in vitro but also in vivo conditions, using a commonly used mouse model of human inflammatory bowel disease. Our findings encourage further studies to determine whether phytanic acid elicits beneficial properties in humans, and suggest that phytanic acid enrichment can be a novel product strategy in the food market.

In this study, the selective extraction and mutual separation of Sc(III) and Y(III) from Ni(II), Co(II) and Mn(II) in acidic media were performed with <i>N</i>-lauroylsarcosine (NLS) in toluene. The experimental results were quantitatively analyzed using the conventional slope analysis method. This method reasonably elucidated reasonably the extraction equilibrium formulation of these metals with LNS. Isostearic acid with only a carboxylic acid group in the molecule extracted Sc(III) and Y(III) in a higher pH region compared with that with LNS having amide and carboxylic acid moieties. Therefore, we found that the amide group included in the molecule structure of NLS plays an important role to extract these metals. Mutual separation of Sc(III) and Y(III) was carried out by a one-step extraction using NLS from Ni(II), Co(II) and Mn(II) in acidic media. Sc(III) is more strongly extracted than Y(III) with NLS, and the separation factor of the metals is quite high at 4.68×10<sup>3</sup>. Furthermore, the stripping of Sc(III) and Y(III) extracted into the organic phase was achieved using appropriate concentrations of various acids.

A deep eutectic solvent (DES) composed of isostearic acid and TOPO was newly found out and investigated for selective recovery of scandium. The four elements used in this study are scandium, iron, yttrium, and aluminum. It was difficult to separate the four elements owing to the overlap of extraction behavior when isostearic acid or TOPO alone in toluene was used, respectively. However, scandium was able to be selectively extracted from other metals using DES prepared by 1:1 mol ratio of isostearic acid and TOPO without toluene. In DES consisting of isostearic acid and TOPO, synergistic and blocking effects with three extractants acted on the extraction selectivity for scandium. Both effects are proved also from the fact that scandium was easily stripped with diluted acidic solutions such as 2 M HCl and H2SO4. Thus, DES extracted selectively scandium and back-extraction was easily achieved. In order to elucidate these phenomena above, the extraction equilibria of Sc(III) using DES dissolved in toluene was investigated in detail. The extraction mechanism of scandium by DES in toluene indicates that the extracted chemical species vary with pH, and that trivalent scandium is extracted by forming stable metal complexes with DESs consisting of five molecules of isostearic acid and five molecules of TOPO.

Blue light causes retinal damage that can lead to ocular diseases such as age-related macular degeneration. In this study, we determined the protective effect of blueberry stem extract (BStEx) and active components on blue light-emitting diode (LED) light-induced retinal photoreceptor cell damage in vitro. Photoreceptor cells cultured in the presence of BStEx or components were exposed to blue light to induce cell damage. BStEx, fractions of BStEx containing proanthocyanidins, chlorogenic acid, catechin, and epicatechin prevented the cell damage and/or inhibited the generation of reactive oxygen species (ROS). Furthermore, BStEx reduced apoptosis and cell death, and inhibited the phosphorylation of p38 mitogen-activated protein kinase and c-Jun N-terminal kinase leading to cellular apoptosis induced by blue light exposure. These findings suggest that BStEx and components exert a protective effect against blue light-induced photoreceptor cell damage through the inhibition of MAPK phosphorylation and ROS production.

The aim of the research described here was to investigate the in vitro immunomodulatory effects of 3RS, 7R, 11R-phytanic acid (3RS-PHY) from the perspective of efficacy against autoimmune diseases. 3RS-PHY is a milk component with strong agonist activity at the peroxisome proliferator activated receptor (PPAR). As PPAR is a therapeutic target for several human diseases, 3RS-PHY intake may have possible health benefits. Recently, we chemically synthesized a preparation of 3RS-PHY and demonstrated that 3RS-PHY inhibited T-cell production of interferon (IFN)-γ. However, the overall immunomodulatory effects were not evaluated. In this study, mouse splenocytes, purified T-cells and B-cells were stimulated by mitogens and incubated with 3RS-PHY, followed by evaluation of cytokine and antibody production. A macrophage-like cell line J774.1 was also incubated with 3RS-PHY to evaluate nitric oxide production. 3RS-PHY decreased mRNA levels not only of IFN-γ but also of interleukin (IL)-2, IL-10 and IL-17A in splenocytes and similar effects were confirmed at the protein level. In addition, 3RS-PHY had a direct action on T-cells with preferential inhibitory effects on Th1 and Th17 cytokines such as IFN-γ and IL-17A. Furthermore, 3RS-PHY suppressed antibody secretion by B-cells and nitric oxide production by J774.1 almost completely, indicating that 3RS-PHY is a bioactive fatty acid with anti-inflammatory properties. These findings encourage further investigations, including in vivo experiments, to evaluate whether 3RS-PHY actually shows the potential to prevent autoimmune diseases, and provide basic information to produce milk and dairy products with an increased 3RS-PHY concentration.

Background/Aim: This study evaluated the effect of blueberry leaf hot water extract (BLEx) on Sjögren's syndrome (SS)-like lacrimal hyposecretion in male non-obese diabetic (NOD) mice. Materials and Methods: NOD or BALB/c mice were fed 1% BLEx or control (AIN-93G) for 2 weeks from the age of 4 to 6 weeks. Pilocarpine-induced tear volume was measured using a phenol red-impregnated thread. The lacrimal glands were evaluated histologically by H&E staining. The IL-1β and TNF-α levels in the lacrimal gland tissue were measured by ELISA. The mRNA expression levels of secretion-related proteins were measured by real-time PCR. LC3 I/II and arginase 1 expression levels were measured by western blot. Results: After feeding with BLEx, pilocarpine-induced tear secretion in NOD mice was increased. In contrast, the mRNA expression levels of the cholinergic muscarinic M3 receptor, aquaporin 5, and ion channels related to lacrimal secretion were not changed by BLEx administration. In addition, the protein expression of arginase 1, which was recently reported to be involved in tear hyposecretion in NOD mice, was also not improved by BLEx administration. Although infiltration in the lacrimal gland of NOD mice was not decreased, the levels of TNF-α and the autophagy-related protein LC3 were significantly suppressed by BLEx treatment. Conclusion: BLEx treatment may ameliorate lacrimal hyposecretion in NOD mice by delaying the progression of autoimmune disease by suppressing autophagy in lacrimal glands.

Although Vaccinium virgatum Aiton leaves and stems inhibit adult T-cell leukemia (ATL) cells, leaves and stems can differ between individual plants and by time and location. In this study, leaf and stem components were profiled in the same individual plant using direct-injection electron ionization-mass spectrometry (DI-EI-MS) metabolomics, with the aims of analyzing the anti-ATL activity, and quantifying proanthocyanidins (PACs). Leaves, stems, and leaf/stem mixtures showed distinct and characteristic spectra. Anti-ATL activity was stronger in stems than leaves, and the PAC content was higher in stems than leaves. These data were subjected to bivariate analysis to identify the factor (m/z) responsible for the inhibitory effect of ATL based on the highest coefficient of determination (R2 ). The results of this DI-EI-MS metabolomics analysis suggest that among PACs contained in V. virgatum stems and leaves, the fragment ion at m/z 149 contributes significantly to anti-ATL activity.

We previously reported that rabbit-eye blueberry (Vaccinium virgatum Aiton) leaves exhibit multiple functions. In this study, we evaluated whether V. virgatum stems can also be used as functional materials similar to leaves and clarified the major constituents and their biological activity (antioxidant activity and anti–adult T cell leukemia (ATL) activity). Water extracts of V. virgatum stems were separated into 19 fractions using a Diaion HP-20 open column. Sugars and organic acids were detected in the highly water-soluble fractions. Polyphenols and proanthocyanidin were detected in the hydrous methanol-soluble fractions. In biological activity evaluations, a difference in antioxidant activity was observed in the water-containing methanol-eluted fractions, and fractions exhibiting anti-ATL activity differed depending on cell type. These results suggest that blueberry stems, like leaves, are rich in polyphenols and exhibit antioxidant activity and inhibit ATL cell growth. In the future, aerial parts of blueberries, including stems and leaves, could be used as functional materials and/or medicinal resources.

We have previously reported that the proanthocyanidin (PAC) fraction of blueberry leaf extract (BB-PAC) inhibits the proliferation of HTLV-1-infected adult T-cell leukemia (ATL) by inducing apoptosis. In the present study, we further analyzed the structure of BB-PAC and elucidated the molecular mechanism underlying the inhibitory function of HTLV-1-infected and ATL cells. After hot water extraction with fractionation with methanol-acetone, BB-PAC was found to be concentrated in fractions 4 to 7 (Fr7). The strongest inhibition of ATL cell growth was observed with Fr7, which contained the highest BB-PAC polymerization degree of 14. The basic structure of BB-PAC is mainly B-type bonds, with A-type bonds (7.1%) and cinchonain I units as the terminal unit (6.1%). The molecular mechanism of cytotoxicity observed around Fr7 against ATL cells was the degradation of JAK1 to 3 and the dephosphorylation of STAT3/5, which occurs by proteasome-dependent proteolysis, confirming that PAC directly binds to heat shock protein 90 (HSP90). JAK degradation was caused by proteasome-dependent proteolysis, and we identified the direct binding of PAC to HSP90. In addition, the binding of cochaperone ATPase homolog 1 (AHA1) to HSP90, which is required for activation of the cofactor HSP90, was inhibited by BB-PAC treatment. Therefore, BB-PAC inhibited the formation of the HSP90/AHA1 complex and promoted the degradation of JAK protein due to HSP90 dysfunction. These results suggest that the highly polymerized PAC component from blueberry leaves has great potential as a preventive and therapeutic agent against HTLV-1-infected and ATL cells.

Blueberry (Vaccinium virgatum Aiton; Kinisato 35 Gou) leaves have recently attracted in-creasing attention as a useful material for the prevention of lifestyle diseases. Here, we examined the effects of the hot water extract of blueberry leaves (BLEx) on lipogenesis and uric acid production in 3T3-L1 adipocytes. The results showed that BLEx suppressed lipid accumulation and the mRNA expression of differentiation markers in 3T3-L1 adipocytes. A fractionation study showed that the highly polymerized proanthocyanidin-rich fraction was responsible for this effect. Upon maturation to adipocytes, 3T3-L1 cells produced uric acid and tumor necrosis factor-α, and hypoxia stimulated the production of uric acid and xanthine oxidoreductase activity. BLEx suppressed the production of uric acid under these conditions. Although BLEx inhibited the enzymatic activity of xanthine oxidase, this activity was observed in several fractions containing catechin, epicatechin, chlorogenic acid, rutin, and low molecular weight proanthocyanidins. Taken together, these results indicate that BLEx contains various compounds with the ability to suppress lipid accumulation and uric acid production in adipocytes.

Demand for scandium (Sc) has been increasing in recent years. However, there are almost no ores containing Sc, and the supply is insufficient because the separation and recovery of Sc as a byproduct from oxide minerals such as ilmenite ore, bauxite, and laterite are difficult. In this study, extraction and separation of Sc from acidic chloride or acidic nitrate solutions containing transition metals such as Fe , Co , Ni , Zn , and Pd were studied using N-lauroylsarcosine (NLS) and tri-n-octylphosphine oxide (TOPO), which together create a “deep eutectic solvent” (DES). Owing to the respective selectivity of NLS and TOPO by different extractive interactions between metal ions and the two extractants in toluene, Sc was effectively and selectively separated even from Fe in the aqueous ammonium nitrate solution, the mutual separation of which is difficult with NLS alone. The mutual separation of Sc and Fe in acidic chloride solution is in general very difficult, while the mutual separation of these metals from acidic nitrate solution is successful. This is due to either anions forming complexes with Sc in the aqueous phase (chloride) or not (nitrate). The potential use of the combination of the NLS with TOPO for selective recovery of Sc from Fe in a refining process is demonstrated. 3+ 3+ 2+ 2+ 2+ 2+ 3+ 3+ 3+ 3+ 3+ 3+ 3+

The aims of this research communication were to investigate the in vivo tissue accumulation of phytanic acid (PA) and any changes in the tissue fatty acid profiles in mice. Previous in vitro studies have demonstrated that PA is a milk component with the potential to cause both beneficial effects on lipid and glucose metabolism and detrimental effects on neuronal cells. However, there is limited information about its in vivo actions. In this study, mice were fed diets containing either 0.00 or 0.05% 3RS, 7R, 11R-PA, which is the isomer found in milk and the human body. After 4 weeks, adipose tissue, liver and brain were harvested and their fatty acid profiles were determined by gas chromatographic analysis. The results showed that PA and its metabolite pristanic acid accumulated in the adipose tissue of PA-fed mice, and that dietary PA decreased the hepatic compositions of several saturated fatty acids such as palmitic acid while increasing the compositions of polyunsaturated fatty acids including linoleic acid and docosahexaenoic acid. However, dietary PA neither accumulated nor had a high impact on the fatty acid profile in the brain. These results suggested that dietary PA could exert its biological activities in adipose tissue and liver, although the brain is relatively less affected by dietary PA. These data provide a basis for understanding the in vivo physiological actions of PA.

The organic solvent is a liquid organic compound capable of dissolving a water-insoluble compound. In the solvent extraction method which is one of metal refining techniques, the large amount of organic solvent plays an important role not only to solubilize the extractant but also to affect the extraction behavior of metal complexes formed in the organic phase. However, most organic solvents have high volatility and toxicity, and their use is limited owing to health damage and environmental burden. In this study, we synthesized activated carbon impregnated extractant without organic solvent and aimed to separate Co and Ni. Specifically, activated carbon was impregnated with 2-isonitrosopropiophenone as extractant, and the effect on Ni and Co separation characteristics was investigated. As a result, the activated carbon was able to selectively adsorb Co over Ni compared to toluene diluent and that this activated carbon had high adsorption capacity for Co and leakage of extractant lower.

Excessive alcohol consumption is a risk factor for liver diseases. Enhancement of alcohol
metabolism could be an effective strategy to prevent these adverse effects since it
promotes the clearance of ethanol and acetaldehyde from the serum. Polyphenol-rich
products have shown to protect against alcohol-related liver damage. Blueberry leaves
have attracted attention as they are rich polyphenols such as proantocyanidins and
chlorogenic acid. In this study, we investigated the effects of a high dose of blueberry
leaf extract (BLEx) on alcohol metabolism during chronic intake of ethanol. Sevenweek old Sprague-Dawley (SD) rats were divided into four groups: normal liquid diet
group (NLD), normal liquid diet + BLEx group (NLD + BLEx), alcohol liquid diet
group (ALD), and alcohol liquid diet + BLEx (ALD + BLEx). Then, rats were fed
experimental diet for 5 weeks and at the end of feeding period, body weight, food intake,
liver weight, indices of liver injury, expression and activity of alcohol metabolismrelated and anti-oxidative enzymes, and levels of carbonyl protein, triglyceride (TG),
and total cholesterol (T-Chol) were measured. Body weight and food intake decreased,
whereas liver aldehyde dehydrogenase (ALDH) activity, liver microsomal cytochrome
P450 2E1 (CYP2E1) protein and mRNA expression, and heme oxygenase 1 (HO-1)
mRNA expression were upregulated by ethanol intake. Dietary BLEx, however, did
not affect any of these ethanol-related changes. Indices of liver injury, expression and
activity of other alcohol metabolism-related enzymes, liver carbonyl protein, TG, and
T-Chol levels were not altered by ethanol and BLEx. Thus, chronic BLEx intake does
not ameliorate the harmful effects of ethanol.DOI: 10.7717/peerj.6989

© 2019 The Royal Society of Chemistry. Natural killer (NK) cells play an important role in the innate immune system by eliminating cancer cells and virally infected cells. Aging and stress attenuate the activity of NK cells, thereby increasing the risk of various diseases. In this study, we demonstrated that the consumption of a small number of kumquats in an in vivo model could suppress elevated plasma corticosterone levels and reverse the decline in splenocyte cytotoxicity caused by restraint stress. Our results identified β-cryptoxanthin (BCX) as an active kumquat component with a NK cell-activating effect, and R-limonene as an active component that mediates not only the anti-stress effect but also NK cell activation by oral administration. In addition, BCX, R-limonene, and R-limonene metabolites were found to enhance IFN-γ production in KHYG-1 cells, a human NK cell line. Collectively, our findings suggest that the ingestion of a few kumquats on a daily basis can help to combat stress and enhance NK cell activity.

© 2018 The Author(s). Background: Among the eight stereoisomers of phytanic acid (PA), the 3RS, 7R, 11R-isomer is naturally occurring and is present in foods and the human body. PA is considered to have possible health benefits in the immune system. However, it remains undetermined whether these effects are elicited by the 3RS, 7R, 11R-PA isomer, because previous studies used a commercially available PA whose isomer configuration is unknown. In this study, we synthesized a preparation of 3RS, 7R, 11R-PA, and investigated its in vitro immunomodulatory effects, especially the T-cell production of interferon (IFN)-γ, which is associated with various autoimmune diseases. This study also investigated the effects of 3RS, 7R, 11R-PA on NF-κB activity in order to address the mechanism of its immunomodulatory effects. Methods: Mouse splenocytes and purified T-cells were stimulated with T-cell mitogens and incubated with 3RS, 7R, 11R-PA, followed by evaluation of IFN-γ production. The effect of 3RS, 7R, 11R-PA on NF-κB activity was also investigated using an A549 cell line with stable expression of an NF-κB-dependent luciferase reporter gene. Results: 3RS, 7R, 11R-PA significantly reduced in vitro IFN-γ production at both the protein and mRNA levels, and was accompanied by decreased expression of T-bet, a key regulator of Th1 cell differentiation. The results indicated that NF-κB-mediated transcriptional activity was significantly decreased by 3RS, 7R, 11R-PA and that GW6471, an antagonist of peroxisome proliferator activated receptor α (PPARα), abrogated the inhibitory effect of 3RS, 7R, 11R-PA on NF-κB activity. Conclusions: The present study suggests that 3RS, 7R, 11R-PA is a functional and bioactive fatty acid, and has a potentially beneficial effect for amelioration of T-cell mediated autoimmune diseases. This study also indicates that interference in the NF-κB pathway via PPARα activation is a potential mechanism of the immunomodulatory effects of 3RS, 7R, 11R-PA.

The effects of the gaseous phase rate of kunugi
(Quercus acutissima) sawdust media mixed with sugi
(Cryptomeria japonica) determined by a three-phasestructure
analysis of the fruiting body yields of shiitake
were investigated. The fruiting body yield on kunugi media
was significantly lower than that on commercially available
hardwood-sawdust-mixture (HSM) media with 64 % water
content. Three-phase-structure analysis showed that the
gaseous phase rate in kunugi media was lower than that in
HSM media. When the gaseous phase rate in kunugi media
was increased to the level in HSM media by decreasing the
water content to 56 %, the fruiting body yield on kunugi
media also increased. These results suggested that kunugi
sawdust could be used for shiitake cultivation if the gaseous
phase rate in the media was optimized. Because sugi
has a lower specific gravity and higher porosity than
kunugi, mixing sugi sawdust up to 30 % with kunugi media
caused an increase in the gaseous phase rate, and the
fruiting body yield reached the same level as that in HSM
media. These results suggested that kunugi media could be
used for shiitake cultivation by mixing with sugi sawdust. -

© 2016 The Chemical Society of Japan. (+)-Pisiferic acid (1) was converted into (+)-12-O-methoxymethylpisiferol (5c) in 3 steps. The rearrangement of 5c with trifluoromethanesulfonic anhydride in pyridine provided (1)- 12-O-methoxymethylpisiferin (6c), which was converted into icetexane phenols 6a, 11, and 14. The ortho-selective oxygenation of 6a and 14 with stabilized 2-iodoxybenzoic acid (SIBX), followed by the reduction of intermediary quinones afforded (1)-barbatusol (2) and (+)-rosmaridiphenol (4) in 49% and 35%, respectively. The oxygenation of 11 using potassium 5-methyl- 2-iodobenzenesulfonate (pre-MIBS) with Oxone® followed by reduction gave (+)-demethylsalvicanol (3) in 59% yield.

© 2015 Japan Society for Bioscience, Biotechnology, and Agrochemistry. In this study, we focused on the anti-inflammatory effect of cordycepin, 3′-deoxyadenosine. Cordycepin potently suppressed nitric oxide production in lipo-polysaccharide-stimulated RAW 264.7 cells in an adenosine receptor-independent manner. In addition, inhibitors for adenosine kinase and nucleoside transporter abrogated the action of cordycepin. Thus, we considered that intracellular metabolism cordycepin is important for the anti-inflammatory effect of cordycepin.

Adult T-cell leukemia/lymphoma (ATLL) is an aggressive disease caused by human T-cell lymphotropic virus type 1 (HTLV-1). As ATLL develops over many years, daily diet may play an important role in its occurrence. In this study, we investigated the growth inhibitory effect of extracts of blueberry leaf fractions on HTLV-1-associated cell lines. The most effective fraction contained highly oligomeric proanthocyanidins (OPA) with a mean degree of polymerization of 3.1. Cell growth inhibition by the OPA fraction was higher in all HTLV-1-associated cell lines than in the MOLT-4 HTLV-1-negative T-cells. It inhibited growth of the HTLV-1-infected T-cell line MT2 and ATLL-derived cell line Su9T01 by inducing apoptosis and G2/M cell cycle arrest. OPA fraction-induced apoptosis of HTLV-1-associated cells required death receptor-mediated caspase-dependent pathways. Treatment-induced G2/M arrest resulted from down-regulation of cyclin B1 and cdc2. The blueberry leaf OPA fraction may be a source of novel compounds for reducing the risk of developing ATLL. © 2013 Elsevier Ltd.

Cryptoquinone, an abietane-type diterpene paraquinone from the bark of Cryptomeria japonica has antifungal and cytotoxic activities, but its biological actions are largely unknown. In this study, we found that para-hydroquinone derivatives inhibited adipocyte differentiation. The actions might have been mediated, at least in part, by activation of the antioxidant-response element induction of phase 2 enzymes and increases in total glutathione.

Green plant-origin electrophilic compounds are a newly recognized class of neuroprotective compounds that provide neuroprotection through activation of the Nrf2/ARE pathway. Electrophilic hydroquinones are of particular interest due to their ability to become electrophilic quinones upon auto-oxidation. Although green plants frequently produce a variety of electrophilic compounds, the detailed mechanisms of action of these compounds remain unknown. Here, we focused on the neuroprotective effects of 11,14-dihydroxy-8,11,13-abietariene (DA1), derived from a para-hydroquinone-type pro-electrophilic compound from the cryptoquinone. DA1 activated the Nrf2/ARE pathway, induced phase 2 enzymes, and increased glutathione, thus protecting neuronal cells from oxidative stress. DA1 had a very broad safety zone (199.41 fold) at least in our system. Thus, DA1 is a novel neuroprotective pro-electrophilic diterpene from green plant. © 2013 Elsevier Ireland Ltd.

In our effort to find new whitening agents, we evaluated the effects of representative chalcones [4-hydroxyderricin (1), xanthoangelol (2), xanthoangelol H (3), deoxyxanthoangelol H (4), and deoxydihydroxanthoangelol H (5)] contained in the stem of Angelica keiskei on tyrosinase and melanin formation in B16 melanoma cells. In addition, the antioxidant effects of these chalcones in ORAC and DPPH assays were also determined. Interestingly, all chalcones (1-5) inhibit melanin formation in B16 melanoma cells, with low cytotoxicity.

A biogas plant using livestock waste in which a methane fermentation process is applied is a useful facility for generating energy. The digestion liquid generated from the biogas plant as a residue has high potential for use as a crop fertilizer. However, high-density estrogens such as 17β-estradiol (E2) are included in livestock waste, and there is little information on the behavior of E2 in the digestion liquid. In this study, a survey of E2 concentration at each process in a biogas plant using livestock waste was carried out. In addition, the efficiencies of E2 removal from the digestion liquid by activated carbon adsorption and soil infiltration were examined. The total concentration of E2 in raw livestock waste was reduced to 2 μg/l after treatment, and the removal efficiency of E2 was about 80% for the plant. The methane fermentation process is important not only for the generation of methane but also for the removal of E2. The proportion of E2 conjugates comprising the total E2 concentration was 10% or less in all treated samples. In the plant, there is no likelihood of an increase in estrogen activity by the cleaving of E2 conjugates. By carrying out activated carbon adsorption to remove E2 from the digestion liquid, a large portion of E2 was removed from the digestion liquid, but an E2 concentration of 0.5 μg/l still remained in the treated digestion liquid. In contrast, it was possible to purify the digestion liquid to an E2 concentration of less than 0.002-0.011 μg/l by soil infiltration. It is thus possible to utilize the digestion liquid as a fertilizer without causing aquatic environmental pollution, but factors such as application rate, soil characteristics, and the E2 concentration of digestion liquid should be considered first. © 2008 Elsevier B.V.

Sawdusts of sugi (Cryptomeria japonica) wood prepared before and after steam drying at 120°C in a kiln were extracted with n-hexane and ethyl acetate to give n-hexane extracts and ethyl acetate extracts. From gas chromatography-mass spectrometry analysis of the ethyl acetate extracts from woods before and after steam drying, the components of 4-epi-cubebol, cubebol, and 2,7(14),10-bis-abolatrien-1-ol-4-one, which existed in the raw sugi wood, were proved to disappear in the steam-dried wood. These components were also absent in the ethyl acetate extract of the steam-condensed solution of waste steam from the kiln outlet. When these three components were treated with 0.2% (v/v) acetic acid solution at 120°C, δ-cadinene was produced as a major product from both 4-epi-cubebol and cubebol by dehydration and cleavage of the cyclopropane ring, and cryptomerone from 2,7(14),10-bisabolatrien-1-ol-4- one by hydration. The chemical changes of the three components presumably occur during steam drying of the sugi wood. © 2008 The Japan Wood Research Society.

This paper describes the degradation of unfilled high temperature vulcanized silicone rubber (HTV-SR) resulting from corona discharges. In this study, corona stress was produced by a needle-plane electrode system, and the chemical and morphological structures at the surface layer of SR before and after corona discharge treatment were analyzed by using the techniques of scanning electron microscope (SEM), Fourier transform infrared (FT-IR), thermogravimetric differential thermal analysis (TG-DTA) and gas chromatography/mass spectrometry (GC/MS). respectively. It can be found that hydrophilic OH groups that are byproducts of ageing can be formed instead of hydrophobic CH3 groups on the surface of aged SR and the corona discharge plays an important role on the temporary loss of hydrophobicity. GC/MS results show that low molecular weight (LMW) silicone fluid disappeared after corona ageing. Also, the endothermic dent appears in the DTA profile because of the occurrence of OH groups. © 2006 IEEE.

From the analysis of drain which was obtained by the steam-dried treatment of Beimatsu (Pseudotsuga menziesii) wood at 80℃ for 15 days, the amounts of phenols, f1avanols and sugars were found to be large. The extracts of organic solvent extractions (hexane and ethyl acetate) of the drain were very small. The adsorbate amount from the drain using HP-20 adsorbent were larger than that of solvent extract. The analysis of solvent extract and HP-20 adsorbate by capillary gas chromatography-mass spectrometer (GC-MS) revealed nine compounds in the drain from Beimatsu wood.

Methanol extract of sawdust of sugi (Cryptomeria japonica) heartwood was fractionated with toluene and n-hexane to give solvent-soluble and solvent-insoluble fractions. The n-hexane-soluble fraction showed the most inhibition activity among the fractions against phytopathogenic microorganisms, namely Fusarium oxysporum, Phytophthora capsici, Pythium splendens, and Ralstonia solanacearum. Sandaracopimarinol and ferruginol, isolated from the n-hexane-soluble fraction, showed moderate antifungal activity against the three fungi and strong antibacterial activity against R. solanacearum. The content of sandaracopimarinol (7.07 g/kg based on the dried sawdust) in the heartwood was about twice that of ferruginol. Sandaracopimarinol and ferruginol strongly inhibited the growth of Gram-positive bacteria but did not show inhibitory action against Gram-negative bacteria except for R. solanacearum. The antibacterial effect of sandaracopimarinol was first found in the present study and was stronger than that of ferruginol. © 2006 The Japan Wood Research Society.

Abstract ###The material balance of carbonization products of Sugi (Cryptomeria japonica D. Don) ###inner bark, Ieaf, and sapwood at 400 ℃ was determined. The yield of charcoal from inner ###bark was the highest. The yield of wood-vinegar from sapwood was the highest. ###The pH of charcoal-dispersed aqueous solution from leaf, inner bark, and sapwood was ###10.35, 9.25, and 5.68, respectively. The ash content of the charcoal from leaf, inner bark, and ###sapwood was l0.70, 7.36,and 0.79 wt.%, respectively. The charcoal from sapwood showed the ###high adsorption capacity for ammonia gas. These results suggest that each ash content of ###charcoals affects the pH and the adsorptive activity.

Hyperthermostable β-glucosidase from Pyrococcus furiosus was enclosed in gelatin gel by cross-linking with transglutaminase. Gelatin-immobilized β-glucosidase was considerably more thermostable than the native enzyme. Lyophilized immobilisate was stored at 90°C for 1 month without loss of activity. The immobilized β-glucosidase catalyzed transglucosylation of 5-phenylpentanol with 10.0 equivalent of cellobiose at pH 5.0 and 70°C for 12 h to afford 5-phenylpentyl β-D-glucopyranoside in 41% yield. The immobilized enzyme was more effective than the native one in transglucosylation. The gelatin-immobilized Pfu-β-glucosidase recovered from the first run of the reaction was reusable on successive runs.

Resin components of Sugi wood were isolated by silica gel column chromatography from the###toluene-hexane-soluble fraction of the methanol extract of the heartwood. On the other hand, after the heartwood has been directly extracted with hexane, the resin components were separated from the hexane extract. The isolated yields of β-sitosterol, sanndapacopimarlnal, sandaracopimarinol, and ferruginol from the hexane extract were nearly comparable to those from the toluene-hexane-soluble###fraction of the methanol extract. Ferruginol. isolated from Sugi wood was benzoylated followed by oxidation with Cr03 in acetic acid to give 12-0-benzoylsugiol, from which sugiol was obtained by methanolysis with anionic ion-exchange resin Amberlite IRA-400 in methanol. The oxidation of###ferruginol with 1.7 equiv. of 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ) in methanol afforded###sugiol directly. The reaction of sugiol with 3.3 equiv. of DDQ followed by acetylation gave 12-0-acetyl-5,6-dehyqrosugiol, from which 5,6-dehydrosugiol was synthesized. 6,7-Dehydroferruginol was synthesized from 12-0-benzoylsugiol in 60% yield at 3 steps.

Pork and beef containing NaCl were stored at 0 °C and changes in 4-hydroxynonenal (HNE) content were analyzed after 0, 3, 7 and 10 days. As an index of the lipid peroxidation level, malonaldehyde (MA) content was also analyzed. In pork, HNE content in samples with 2% NaCl increased (P<0.05) after 7 and 10 days of storage. In beef, HNE content in all samples increased during storage. The HNE content in samples with NaCl was higher than those of the control, after 7 and 10 days of storage, although the difference was not always significant. Judging from MA content, NaCl may act as a pro-oxidant in pork and beef. HNE may accumulate in pork and beef in which lipid peroxidation is progress. © 2003 Published by Elsevier Ltd.

Sugi woods treated with acetic acid aqueous solution were found to become lighter in weight. Treated and untreated sugi woods were carbonized at 400°C to afford wood-vinegar, wood-tar and charcoal. Yield of wood-vinegar from the pretreated wood was increased, but yields of wood-tar and charcoal were decreased. Yields of wood-vinegar and wood-tar were almost constant, though yield of charcoal was slightly decreased with the increase of acetic acid aqueous solution concentration. Components in wood-vinegar from the treated and untreated sugi woods were determined by capillary gas chromatography (capillary GC). Amounts of 2-furaldehyde and 5-hydroxymethyl-2-furaldehyde in wood-vinegar from the treated wood were increased, but amounts of carboxylic acids, phenols, pyrocatechol, guaiacols, and maltol were almost constant. Amount of 2-furaldehyde were increased with the increase of acetic acid aqueous solution concentration from 0 to 3%, and almost constant from 3% to 30%.

The contents of 4-Hydroxy-2-nonenal (HNE), cytotoxic aldehyde, in smoked meat products (ham, bacon and sausage) were analyzed. All the samples analyzed contained HNE, although large differences in the contents between the different samples were observed. In one lot of ham (H1) and wiener sausage (WS1) a high level in HNE was observed. The changes of HNE contents of pork meats containing 0, 0.1, 0.5 and 1% Sugi wood vinegar (SWV) stored at 0 °C were also analyzed for 7 days. As an index of lipid peroxidation level, malonaldehyde (MA) contents were also analyzed in these samples. After 7 days of storage, HNE was detected only in pork meats containing 1% SWV and the level was similar to those of HI and WS1. Judging from MA contents, SWV may act as a pro-oxidant in pork meats and HNE may accumulate in pork in which lipid peroxidation is in progress. © 2002 Elsevier Science Ltd. All rights reserved.

Contents of 4-hydroxy-2E-hexenal (HHE), hepatotoxic aldehydes, in smoked fish meat products (smoked salmon and fish meat sausage) were analyzed. Large differences in these contents between the different samples were observed. Very low levels of HHE were detected in fish meat sausage samples. However, a high level of HHE was observed in one batch of smoked salmon. Changes of HHE contents in yellowtail meat containing cherry and sugi wood vinegar stored at 0°C were also analyzed for 7 days. Malonaldehyde (MA) was also analyzed in these samples as an index of the lipid peroxidation level. After 3 or 7 days of storage, HHE contents in both wood vinegar-added samples were significantly higher, but MA contents were significantly lower than those of the control.

Effect of wood vinegar on lipid peroxidation of fish

記述言語:日本語 掲載種別:研究論文(学術雑誌) 出版者・発行元:Fisheries Science
The lipid peroxidation in smoked salmon and two wood vinegars {commercial wood vinegar (VVV) and cherry wood vinegar (CVVV)} treated fish meat was evaluated using malonaldehyde (MA), 4-hydroxy-2E-hexenal (HHE) and carbonyl protein (CP) as indices for a 7-day storage period at 4°C. Smoked salmon samples showed a high variation of MA, and extremely high levels of MA and HHE indicate uneven distribution of smoke constituents and high pro-oxidative activity respectively, making smoking unsuitable. Of the two wood vinegars, CVVV treated fish meat gave high levels of HHE, MA and CP compared with that of the control, demonstrating CVVV as a pro-oxidant. However, in VVV treated samples, the control showed a higher level of MA compared with that of treated samples, whereas the treated samples showed higher levels of HHE and CP compared with that of the control, making it difficult to decide whether VVV suppresses or stimulates the peroxidation. In both wood vinegar treated samples, the variation of indices during storage period does not show a clear pattern in relation to type of wood vinegar used or its concentration. This indicates a complexity of the peroxidative mechanism due to its high dependency on numerous factors. © 2002, The Japanese Society of Fisheries Science. All rights reserved.

Methanol extracts of sugi (Cryptomeria japonica D. Don) wood were separated into toluene-insoluble, hexane-toluene-insoluble, and hexane-toluene-soluble fractions. Ferruginol, sugiol, sandaracopimarinol, sandaracopimarinal, phyllocladanol, and β-sitosterol were obtained from the hexane-toluene-soluble fraction by column chromatography on silica gel. The inhibitory activity of each terpenoid on mycelial growth of shiitake (Lentinula edodes (Berk.) Pegler) was examined on a potato dextrose and agar medium at 25°C. Ferruginol, sugiol, and sandaracopimarinol were found to inhibit the mycelial growth of shiitake at a concentration of 5000 μg cm-3. The 50% inhibition concentration of ferruginol was determined at ca. 100 μg cm-3and that of sandaracopimarinol at ca. 1000 μg cm-3. The mycelial growth inhibition of shiitake is probably due to a synergistic effect of ferruginol and sandaracopimarinol, which are the major terpenoids in sugi wood.

The material balance of carbonization products (wood-gas, wood-vinegar, wood-tar and charcoal) prepared from the sapwood and the heartwood of Sugi (Cryptomerica japonica D. Don) at various temperatures was determined. The evolution of both carbon monoxide and carbon dioxide mainly occurred at the carbonization temperature below 600 °C and that of hydrogen and methane at 600-800 °C. Total yield of the wood-vinegar and the wood-tar was almost constant at 500-800 °C. On the other hand, the yield of the charcoal decreased because of the evolution of the wood gas with an increase in carbonization temperature. The wood-vinegars prepared at the temperature over 400 °C were found to consist of carboxylic acids such as acetic acid and propionic acid, methanol, acetone, furans, alkylphenols, guaiacols, cyclotene and maltol by capillary gas chromatography. Since the constituent varieties and contents of the wood-vinegars prepared at both 400 °C and 800 °C were very similar each other, the wood-vinegar of Sugi wood chiefly produced below 400 °C. FT-IR spectra of the charcoals showed the generation of carbonyl and olefin groups at 300-400 °C and then the formation of aromatic rings along with the disappearance of carbonyl groups over 600 °C. The production of radical species in the charcoals carbonized at 300-600 °C was observed by ESR, on the contrary, the charcoals carbonized over 700 °C were inactive. The specific surface area and the pore volume of the charcoal of Sugi sapwood increased with an increase in carbonization temperature. The pH of charcoal-dispersed aqueous solution increased with an increase in carbonization temperature. The high adsorptive activity of the charcoal carbonized at 400 °C for ammonia gas and that at 800 °C for hydrogen sulfide gas seemed to be dependent on acidic and basic properties of the charcoals, respective-ly.

A novel and direct synthesis of hydroperoxy compounds from various types of conjugated olefins was established via cobalt(II) porphyrin-catalyzed hydroperoxygenation. The reaction of α,β,γ,δ-unsaturated carbonyl compounds, acrylic esters, α-substituted acrylic esters and styrene derivatives with molecular oxygen and triethylsilane in the presence of a catalytic amount of cobalt(II) porphyrin proceeded rapidly to give the corresponding hydroperoxygenated compounds in high or moderate yields.

Derivatives of (11E)-10-oxo-11-octadecen-13-olide (1) and its seco-acid 2 were synthesized from linoleic acid for purpose of elucidation of their cytotoxic activity. Linoleic acid was converted to (13S, 9Z, 11E)-13-hydroxy-9,11-dienoic acid (4) by soybean lipoxygenase-catalyzed oxidation followed by treatment with NaBH_4. The hydroxy acid 4 was cyclized by the Yamaguchi method and by the Mitsunobu method, to give 14-membered lactones S-5 and R-5, respectively, which reacted with oxygen and triethylsilane in the presence of Co(tdcpp) as a catalyst followed by acetylation-decomposition of the intermediary hydroperoxide to produce S-1 and R-1. Lipase-catalyzed hydrolysis of R-1 gave hydroxyketo acid R-2. The reduction-oxygenation of dienoic ester 7, prepared from 4 by treating with diazomethane and then t-butyldimethylsilyl chloride, afforded oxo derivative 8, which was deprotected to give hydroxyketo acid S-2. The other derivatives related to 1 and 2 were also synthesized by the similar manner described above. On the other hand, (E)-4-hydroxy-2-nonenal (HNE) and (E)-4-hydroxy-2-hexenal (HHE), cytotoxic aldehydes produced during lipid peroxidation in biological system, were synthesized in one step from commercially available 2,4-alkadienals by the Co(tdcpp)-catalyzed reduction-oxygenation. The deuterium-labeled HNE and HHE were prepared by use of triethyldeuterosilane and 2-propan(old) instead of triethylsilane and 2-propanol on the reduction-oxygenation of 2,4-alkadienals. The IC_<50> values of the fatty acid derivatives were determined against P388 mouse leukemia cells. The macrolide 1 showed the strongest cytotoxicity among the derivatives, however, no difference in the cytotoxicity was found between the optically active and racemic forms of 1. The cytotoxicity of the macrolides was enhanced, respectively, in comparison with that of the corresponding seco-acids. The enone moiety of 1 and 2 is assumed to be important for enhancing the cytotoxic action.

Both the S and R enantiomers of (E)-13-hydroxy-10-oxo-11-octadecenoic acid (1) and (E)-10-oxo-11-octadecen-13-olide (2) had similar IC50values against P388 mouse leukemia cells; i.e. the stereochemistry of the asymmetric center of 1 and 2 had no influence on the cytotoxic activity. Bioassay results of various compounds related to 1 and 2 suggests that the 10-oxo and lactone moieties of 2 were important for enhancing the cytotoxicity. © 1998, Taylor & Francis Group, LLC.

Various samples of fish meat were examined for the formation of the hepatotoxic aldehyde, 4-hydroxy-trans-2-hexenal (HHE). HHE was detected in all samples analyzed at the concentration of 1.5–39.3 nmol/g. Yellowtail meat contained more HHE than 4-hydroxy-trans-2-nonenal (HNE). The HHE and malonaldehyde concentration increased during 13 days of storage at 0°C in the meat of yellowtail. On the other hand, no HNE was detected during storage. © 1997, Taylor & Francis Group, LLC. All rights reserved.

We recently isolated (11E)-13-hydroxy-10-oxooctadec-11-enoic acid (1) and its fourteen-membered lactone 2 as cytotoxic constitutents of the extract of corn, but we could not determined their absolute configuration of the asymmetric carbon at C-13. Therefore, for purposes of elucidation of the absolute configuration of natural 1 and 2 and comparison between their cytotoxic behavior, we attempted syntheses of both their R- and S-enantiomers from linoleic acid via lipoxygenase- and cobalt porphyrin-catalyzed oxygenation as key step-reactions. Linoleic acid (3) was converted into (13S, 9Z, 11E)-13-hydroperoxyoctadeca-9,11-dienoic acid (4) by soybean lipoxygenase-catalyzed oxygenation, which was treated with NaBH_4 and then diazomethane to give 13S-hydroxy ester 5. Dienoic esters 6a-c were obtained from 5 by protection of the hydroxy group and allowed to react with oxygen and triethylsilane in the presence of a catalytic amount of cobalt porphyrin followed by acetylation of intermediary hydroperoxides, to afford 10-oxo compounds 7a-c and 12-oxo ones 8a-c: The yield of 7 increased with bulkiness of the protection group of 6. Hydrolysis of 7c by use of lipase and then deprotection gave 13S-keto acid S-1. On the other hand, 13R-keto acid R-1 was synthesized by lipase-catalyzed hydrolysis of the corresponding lactone R-2. (13S, 9Z, 11E)-13-hydroxyoctadeca-9,11-dienoic acid (10), obtained from 3 by lipoxygenase-catalyzed oxygenation and reduction with NaBH_4, was cyclized by the Yamaguchi method and by the Mitsunobu method, to give 14-membered lactones S-11 and R-11, respectively. The cobalt porphyrin-catalyzed oxygenation of S-11 and R-11 produced the corresponding 10-oxo lactones S-2 and R-2. Thus, we synthesized successfully the both enantiomers of 1 and 2 from linoleic acid in short steps and now evaluate their cytotoxic activity in progress.
