Abstract
Tribulus terrestris (T. terrestris) has been used as a traditional medicine for the treatment of a variety of diseases, including inflammation, edema and hypertension. The aqueous and ethanol extracts of T. terrestris contain alkaloids, flavonoids, tannins, quinines and phenolic compounds. Tribulusamide D is a compound that has been isolated from the ethanol extract of T. terrestris. The present study investigated the anti‑inflammatory effect of tribulusamide D on lipopolysaccharide (LPS)‑stimulated RAW 264.7 macrophages. Tribulusamide D inhibited the production of LPS‑induced nitric oxide and prostaglandin E2, by reducing the expression of inducible nitric oxide synthase and cyclooxygenase‑2 expression, respectively. The expression of these genes associated with inflammation was determined using reverse transcription‑polymerase chain reaction and western blot analysis. Furthermore, tribulusamide D reduced the expression of LPS‑induced inflammatory cytokines, including interleukin (IL)‑6, IL‑10 and tumor necrosis factor‑α. They were quantified using an enzyme‑linked immunosorbent assay. In addition, the present study confirmed that the inhibitory effects of tribulusamide D on the inflammatory response were mediated through inactivation of mitogen‑activated protein kinase p38 and inhibition of nuclear localization of nuclear factor‑B, which were also determined by western blot analysis. To the best of our knowledge, the current study is the first to demonstrate that tribulusamide D exerts anti‑inflammatory activity by altering the expression of inflammatory mediators and cytokines, indicating that tribulusamide D could be developed as a potential therapeutic agent for the treatment of inflammatory disorders.

Abstract
Moringa oleifera Lam. is a tropical plant, used for centuries as food and traditional medicine. The aim of this study was to develop, validate and biochemically characterize an isothiocyanate-enriched moringa seed extract (MSE), and to compare the anti-inflammatory effects of MSE-containing moringa isothiocyanate-1 (MIC-1) with a curcuminoid-enriched turmeric extract (CTE), and a material further enriched in its primary phytochemical, curcumin (curcumin-enriched material; CEM). MSE was prepared by incubating ground moringa seeds with water to allow myrosinase-catalyzed enzymatic formation of bioactive MIC-1, the predominant isothiocyanate in moringa seeds. Optimization of the extraction process yielded an extract of 38.9% MIC-1. Phytochemical analysis of MSE revealed the presence of acetylated isothiocyanates, phenolic glycosides unique to moringa, flavonoids, fats and fatty acids, proteins and carbohydrates. MSE showed a reduction in the carrageenan-induced rat paw edema (33% at 500 mg/kg MIC-1) comparable to aspirin (27% at 300 mg/kg), whereas CTE did not have any significant effect. In vitro, MIC-1 at 1 μM significantly reduced the production of nitric oxide (NO) and at 5 μM, the gene expression of LPS-inducible nitric oxide synthase (iNOS) and interleukins 1β and 6 (IL-1β and IL-6), whereas CEM did not show any significant activity at all concentrations tested. MIC-1 (10μM) was also more effective at upregulating the nuclear factor (erythroid-derived 2)-like 2 (Nrf2) target genes NAD(P)H:quinone oxidoreductase 1 (NQO1), glutathione S-transferase pi 1 (GSTP1), and heme oxygenase 1 (HO1) than the CEM. Thus, in contrast to CTE and CEM, MSE and its major isothiocyanate MIC-1 displayed strong anti-inflammatory and antioxidant properties in vivo and in vitro, making them promising botanical leads for the mitigation of inflammatory-mediated chronic disorders.

Abstract
BACKGROUND In our continuing search for anti-inflammatory agents from Thai herbs, Etlingera pavieana (Pierre ex Gagnep.) R.M.Sm. showed potent inhibition on nitric oxide (NO) production in lipopolysaccharide (LPS)-induced macrophages. However, the mechanism behind its inhibitory effect has not been yet explored, and little is known regarding its bioactive compounds responsible for the anti-inflammatory effect. OBJECTIVE In the present study, anti-inflammatory effect of hexane, ethyl acetate, and water fractions of rhizomal ethanol extracts of E. pavieana was evaluated for their inhibition on NO production and mechanism in LPS-stimulated macrophages. Active compounds responsible for such anti-inflammatory activity were identified. MATERIALS AND METHODS Inhibitory activities on NO production were performed in LPS-stimulated RAW264.7 macrophage. Cytotoxicity of plant extracts was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, mRNA and protein expressions by reverse transcription-polymerase chain reaction and Western blotting analysis, respectively. Anti-inflammatory compounds were isolated by activity-guided isolation technique using column chromatography. RESULTS Ethyl acetate fraction of E. pavieana (EPE) showed the most potent inhibitory effect on NO production in macrophages. EPE significantly decreased NO production and inhibited inducible nitric oxide synthase (iNOS) protein and mRNA expression in a dose-dependent manner. Furthermore, the level of nuclear factor-kappa B p65 subunit was markedly reduced in activated cells treated with EPE. Four phenolic compounds, 4-methoxycinnamyl alcohol (1), trans-4-methoxycinnamaldehyde (2), 4-methoxycinnamyl p-coumarate (3), and p-coumaric acid (4), were obtained from bioactivity-guided isolation technique. CONCLUSIONS The anti-inflammatory property contained in E. pavieana rhizome extract and conferred through inhibition of iNOS expression, and NO formation provides scientific evidence and support for the development of new anti-inflammatory agents based on extracts from this plant. SUMMARY Ethyl acetate fraction (EPE) of Etlingera pavieana showed the most potent inhibitory effect on NO production in LPS-induced macrophagesFour phenolic compounds, 4-methoxycinnamyl alcohol (1), trans-4-methoxycinnamaldehyde (2), 4-methoxycinnamyl p-coumarate (3) and p-coumaric acid (4), responsible for the anti-inflammatory effect of EPE were isolated.

Abstract
Macrophages play a critical role in a variety of inflammatory diseases. Activation of Keap1/Nrf2/HO-1 signaling results in inactivation of macrophages and amelioration of inflammatory and autoimmune conditions. Hence, discovery for the activators of Keap1/Nrf2/HO-1 signaling has become a promising strategy for treatment inflammatory diseases. In the current study, the anti-inflammatory potential of 7-deacetylgedunin (7-DGD), a limonin chemical isolated from the fruits of Toona sinensis (A. Juss.) Roem, was intensively examined in vivo and in vitro for the first time. Results showed that 7-DGD alleviated mice mortality induced by LPS. Mechanistic study showed that 7-DGD suppressed macrophage proliferation via induction of cell arrest at the G0/G1 phase. Furthermore, 7-DGD inhibited iNOS expression, which is correlated with the increases of NQO1, HO-1 and UGT1A1 mRNA expression as well as HO-1 protein expression level in the cells. More importantly, 7-DGD markedly decreased Keap1 expression, promoted p62 expression, and facilitated Nrf2 translocation and localization in the nucleus of macrophages, and in turn up-regulates these anti-oxidant enzymes expression, eventually mediated anti-inflammatory effect. Collectively, 7-DGD suppresses inflammation in vivo and in vitro, indicating that the compound is valuable for further investigation as an anti-inflammatory agent in future.

Abstract
3, 4-Dihydroxybenzalacetone (DBL) is a constituent of Phellinus linteus. This study demonstrated the protective effect of DBL on lipopolysaccharide (LPS)-induced acute lung injuries in mice. Pretreatment with DBL significantly improved LPS-induced histological alterations in lung tissues. In addition, DBL markedly reduced the total cell number, the leukocytes, the protein concentrations, and decreased the release of nitrite, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-6 and the activities of matrix metalloproteinase (MMP)-2 and -9 in the bronchoalveolar lavage fluid. DBL also inhibited the W/D ratio and myeloperoxidase activity in the lung tissues. Western blot analysis indicated DBL efficiently blocked the protein expressions of inducible nitric oxide synthase, cyclooxygenase-2, MMP-2, MMP-9, and the phosphorylation of mitogen-activated protein kinase (MAPK), phosphoinositide-3-kinase (PI3K), AKT, Toll-like receptor 4 (TLR4) and nuclear factor (NF)-κB. Moreover, DBL enhanced the expression of anti-oxidant proteins, such as superoxide dismutase (SOD), catalase and glutathione peroxidase (GPx). Based on our results, DBL might be a potential target for attenuating tissue oxidative injuries and nonspecific pulmonary inflammation.

Abstract
The diet polyphenols are a secondary metabolites of plants able to act on inflammation process. Their anti-inflammatory activity is articulated through several mechanisms that are related to their antioxidative and radical scavengers properties. Our work is focused on a novel approach to inflammatory disease management, based on anti-glycative and matrix metalloproteinases (MMPs) inhibition effects, as a connected phenomena. To better understand these correlation, polyphenols Structure-Activity Relationship (SAR) studies were also reported. The antioxidant polyphenols inhibit the AGEs at different levels of the glycation process in the following ways: (1) prevention of Amadori adduct oxidation; (2) trapping reactive dycarbonyl compounds; (3) attenuation of receptor for AGEs (RAGE) expression. Moreover, several flavonoids with radical scavenging property showed also MMPs inhibition interact directly with MMPs or indirectly via radical scavengers and AGEs reduction. The essential polyphenols features involved in these mechanisms are C2-C3 double bond and number and position of hydroxyl, glycosyl and O-methyl groups. These factors induce a change in molecular planarity interfering with the hydrogen bond formation, electron delocalization and metal ion chelation. In particular, C2-C3 double bond improve the antioxidant and MMPs inhibition, while the hydroxylation, glycosylation and methylation induce a positive and negative correlation, respectively.

Abstract
Here we investigated the effect of green lipped mussel oil complex (GLMOC) on inflammation and underlying mechanism in lipopolysaccharide stimulated RAW264.7 murine macrophage cells. GLMOC containing green lipped mussel oil (GLMO), olive oil, and vitamin E (10:20:1) can induce significant suppression of iNOS, leading to reduced nitric oxide synthesis, and cyclooxygenase-2, leading to reduced prostaglandin E2 synthesis. In addition, it down-regulated the release of pro-inflammatory cytokines, including tumor necrosis factor-α, interleukin (IL)-6, and IL-1β. Similar to upstream signaling mediators, GLMCO inhibited the degradation of inhibitory κB, nuclear translocation of NF-κB, and phosphorylation of mitogen activated protein kinases (MAPKs) in a dose-dependent manner. Among the components of GLMOC, GLMO was responsible for anti-inflammatory efficacy. Taken together, GLMOC induces anti-inflammatory activity via regulating NF-κB and MAPK signaling in lipopolysaccharide-induced RAW264.7 cells, providing underlying mechanisms that elucidate the anti-inflammatory efficacy of GLMOC.

Abstract
Vitex spp. have been reported as constituents of herbal preparations, namely Vitex peduncularis, commonly used in Asian countries. Unlike other species extensively investigated, reports on the biological activities and chemical profile of V. peduncularis are still scarce. In this work, the polyphenolic profile of V. peduncularis stem bark was unveiled, revealing a high content of apigenin and luteolin derivatives. More than 20 polyphenols were identified and quantitated for the first time, including C-rhamnosyl flavones infrequently reported. Regarding potential anti-inflammatory properties, the methanolic extract of the stem bark significantly reduced the levels of NO in macrophages, which may be a consequence of scavenging effect upon •NO. Significant inhibition of phospholipase A2 activity was also noted. Consequently, the therapeutic applicability of this edible plant is also broadened due to the anti-inflammatory properties found.

Abstract
Cornea is an avascular transparent tissue. Ocular trauma caused by a corneal alkali burn induces corneal neovascularization (CNV), inflammation, and fibrosis, leading to vision loss. The purpose of this study was to examine the effects of Zerumbone (ZER) on corneal wound healing caused by alkali burns in mice. CNV was induced by alkali-burn injury in BALB/C female mice. Topical ZER (three times per day, 3μl each time, at concentrations of 5, 15, and 30μM) was applied to treat alkali-burned mouse corneas for 14 consecutive days. Histopathologically, ZER treatment suppressed alkali burn-induced CNV and decreased corneal epithelial defects induced by alkali burns. Corneal tissue treated with ZER showed reduced mRNA levels of pro-angiogenic genes, including vascular endothelial growth factor, matrix metalloproteinase-2 and 9, and pro-fibrotic factors such as alpha smooth muscle actin and transforming growth factor-1 and 2. Immunohistochemical analysis demonstrated that the infiltration of F4/80 and/or CCR2 positive cells was significantly decreased in ZER-treated corneas. ZER markedly inhibited the mRNA and protein levels of monocyte chemoattractant protein-1 (MCP-1) in human corneal fibroblasts and murine peritoneal macrophages. Immunoblot analysis revealed that ZER decreased the activation of signal transducer and activator of transcription 3 (STAT3), with consequent reduction of MCP-1 production by these cells. In conclusion, topical administration of ZER accelerated corneal wound healing by inhibition of STAT3 and MCP-1 production.

Anti-Inflammatory Activity and Structure-Activity Relationships of Brominated Indoles from a Marine Mollusc. Mar Drugs 2017; 15:md15050133. [PMID: 28481239 PMCID: PMC5450539 DOI: 10.3390/md15050133] [Citation(s) in RCA: 25] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2017] [Revised: 04/18/2017] [Accepted: 05/02/2017] [Indexed: 12/31/2022] Open
Abstract
Marine molluscs are rich in biologically active natural products that provide new potential sources of anti-inflammatory agents. Here we used bioassay guided fractionation of extracts from the muricid Dicathais orbita to identify brominated indoles with anti-inflammatory activity, based on the inhibition of nitric oxide (NO) and tumour necrosis factor α (TNFα) in lipopolysaccharide (LPS) stimulated RAW264.7 macrophages and prostaglandin E2 (PGE2) in calcium ionophore-stimulated 3T3 ccl-92 fibroblasts. Muricid brominated indoles were then compared to a range of synthetic indoles to determine structure-activity relationships. Both hypobranchial gland and egg extracts inhibited the production of NO significantly with IC50 of 30.8 and 40 μg/mL, respectively. The hypobranchial gland extract also inhibited the production of TNFα and PGE2 with IC50 of 43.03 µg/mL and 34.24 µg/mL, respectively. The purified mono-brominated indole and isatin compounds showed significant inhibitory activity against NO, TNFα, and PGE2, and were more active than dimer indoles and non-brominated isatin. The position of the bromine atom on the isatin benzene ring significantly affected the activity, with 5Br > 6Br > 7Br. The mode of action for the active hypobranchial gland extract, 6-bromoindole, and 6-bromoisatin was further tested by the assessment of the translocation of nuclear factor kappa B (NFκB) in LPS-stimulated RAW264.7 mouse macrophage. The extract (40 µg/mL) significantly inhibited the translocation of NFκB in the LPS-stimulated RAW264.7 macrophages by 48.2%, whereas 40 µg/mL of 6-bromoindole and 6-bromoistain caused a 60.7% and 63.7% reduction in NFκB, respectively. These results identify simple brominated indoles as useful anti-inflammatory drug leads and support the development of extracts from the Australian muricid D. orbita, as a new potential natural remedy for the treatment of inflammation.

A multifunctional alanine-rich anti-inflammatory peptide BCP61 showed potent inhibitory effects by inhibiting both NF-κB and MAPK expression. Inflammation 2017; 40:688-696.

Abstract
The purified BCP61 was reported to be a unique low-molecular-weight (MW) anti-microbial peptide because of its non-identical alanine-rich N-terminal sequence. In this study, we investigated the anti-inflammatory effects of BCP61 on induction of inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), pro-inflammatory cytokines, nuclear factor-kappa B (NF-κB), and mitogen-activated protein kinases (MAPKs) in lipopolysaccharide (LPS)-stimulated Raw 264.7 cells. The treatment with BCP61, with varying concentrations of 10, 50, and 100 μg/mL, inhibited levels of expression of LPS-induced NF-κB and MAPKs (extracellular signal-related kinases (ERKs), c-Jun NH2-terminal kinase (JNK), and mitogen-activated protein (p38)) as well as production of pro-inflammatory mediators, such as nitric oxide (NO), prostaglandin E2 (PGE2), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6). The results suggested that BCP61 prevents inhibitor of kappa B (IκBα) phosphorylation and degradation, thereby inhibiting the nuclear translocation of the p65 protein. We do report that the use of BCP61 in the treatment of inflammation as well as microbial infection could be a potent therapeutic candidate.

Abstract
Althaea rosea (Linn.) is a medicinal plant from China and Korea that has been traditionally used to control inflammation, to stop bedwetting and as a mouthwash in cases of bleeding gums. Its flowers are employed medicinally for their emollient, demulcent and diuretic properties, which make them useful in chest complaints. Furthermore, a flower extract decoction is used to improve blood circulation, for the treatment of constipation, dysmenorrhoea, haemorrhages, etc. However, the possible mechanisms of the immune-stimulatory effect remains to be elucidated. Therefore, we investigated the role of Althaea rosea flower (ARF) extracts in the immune-stimulatory effect of macrophages and the underlying mechanisms of action. ARF water extract (ARFW) could dose-dependently increase NO production and cytokines (IL-6 and TNF-α). We also found that ARFW significantly increased the expression of iNOS and COX-2 proteins in RAW264.7 cells. Consistent with these results, MAPK protein (JNK, ERK, p38) expression levels were induced after treatment with ARFW. Additionally, ARFW showed a marked increase in the phosphorylation level of IκBα and subsequent IκBα degradation allowing NF-κB nuclear translocation. These results suggest that the immune-stimulatory effect of A. rosea flower extracts is mediated through the translocation of NF-κB p65 subunit into the nucleus from the cytoplasm and subsequent activation of pro-inflammatory cytokines (IL-6 and TNF-α) and other mediators (iNOS and COX-2), which occurs mainly through MAPK signalling pathway. Thus, we suggest that ARFW could be considered as a potential therapeutic agent useful in the development of immune-stimulatory compounds.

Abstract
CQMUH-011, a novel adamantane sulfonamide compound, was shown to suppress macrophage activation and proliferation in our previous study. However, it is unknown whether CQMUH-011 has anti-inflammatory and hepatoprotective properties. In this study, we investigated the potential effects and mechanisms of CQMUH-011 on lipopolysaccharide (LPS)-induced RAW264.7 cell activation in vitro and LPS- and D-galactosamine (D-GalN)-induced fulminant hepatic failure (FHF) in vivo. The results showed that in RAW264.7 cells challenged by LPS, CQMUH-011 inhibited cell proliferation and induced cell cycle arrest and apoptosis. Furthermore, CQMUH-011 reduced tumor necrosis factor (TNF)-α and interleukin (IL)-1β production and down-regulated the overexpression of toll-like receptor 4 (TLR4) and nuclear factor (NF)-κB induced by LPS in RAW264.7 cells. In vivo, CQMUH-011 reduced serum levels of aspartic aminotransferase and alanine transaminase and improved the mortality and hepatic pathological damage induced by LPS/D-GalN in mice. Moreover, CQMUH-011 significantly inhibited the serum levels of proinflammatory mediators, including TNF-α, IL-6, IL-1β, nitric oxide (NO), and prostaglandin E2 (PGE2), and down-regulated the protein expression of TLR4, p38 mitogen-activated protein kinases, NF-κB, NF-κB inhibitor α (IκBα), IκB kinase β (IKKβ), cyclooxygenase-2 (COX-2) and inducible NO synthases (iNOS) induced by LPS/D-GalN in mice. In conclusion, these results demonstrated that CQMUH-011 has a notable anti-inflammatory effect and protects mice from LPS/D-GalN-induced FHF and that the molecular mechanisms might be related to the inhibition of the TLR4/NF-κB signaling pathway activation, the subsequent decrease in proinflammatory mediator production, and the inhibition of macrophage activation.

Abstract
Oxidative stress results from an imbalance of the reactive oxygen species/reactive nitrogen species (ROS/RNS) production and the oxidants defense system. Extensive research during the last decades has revealed that oxidative stress can mediate cancer initiation and development by leading not only to molecular damage but also to a disruption of reduction-oxidation (redox) signaling. In order to provide a global overview of the redox signaling pathways, which play a role in cancer formation, we conducted a systematic literature search in PubMed and ISI Web of Science and identified 185 relevant reviews published in the last 10 years. The 20 most frequently described pathways were selected to be presented in this systematic review and could be categorized into 3 groups: Intracellular ROS/RNS generating organelles and enzymes, signal transduction cascades kinases/phosphatases and transcription factors. Intracellular ROS/RNS generation organelles are mitochondria, endoplasmic reticulum and peroxisomes. Enzymes, including NOX, COX, LOX and NOS, are the most prominent enzymes generating ROS/RNS. ROS/RNS act as redox messengers of transmembrane receptors and trigger the activation or inhibition of signal transduction kinases/phosphatases, such as the family members of protein tyrosine kinases and protein tyrosine phosphatases. Furthermore, these reactions activate downstream signaling pathways including protein kinase of the MAPK cascade, PI3K and PKC. The kinases and phosphatases regulate the phosphorylation status of transcription factors including APE1/Ref-1, HIF-1α, AP-1, Nrf2, NF-κB, p53, FOXO, STAT, and β-catenin. Finally, we briefly discuss cancer prevention and treatment opportunities, which address redox pathways and further research needs.

Abstract
Neuroinflammation plays a central role in the etiology and progression of Alzheimer's disease (AD), a neurodegenerative disorder, characterized by a gradual loss of memory functions. Thus, it has been proposed that agents that could reduce inflammatory processes in AD brains might be useful for the treatment of the disease. Methyl jasmonate (MJ) is a bioactive compound, which has been reported to exhibit anti-amnesic and in vitro anti-inflammatory activities. In this study, we further examine its effects on the brain levels of biomarkers of neuroinflammation in lipopolysaccharide (LPS)-induced memory deficits in mice. Mice (n=6) were pretreated intraperitoneally with MJ (10-40mg/kg), donepezil (DP) (1mg/kg) or vehicle (10mL/kg) for 30min prior to injection of LPS (250μg/kg, i.p) daily for 7days. Thirty minutes after LPS administration on day 7, memory function was assessed using Y-maze test. After Y-maze test, the levels of biomarkers of neuroinflammation: prostaglandin E2 (PGE2), tumor necrosis factor α (TNFα) and interleukin 1β (IL1β) were estimated in brain tissue homogenates using ELISA. Expressions of positive cells of cyclooxygenase-2 (COX2), inducible nitric oxide synthase (iNOS), nuclear factor kappa B (NF-κB) and amyloid-beta (Aβ) in the prefrontal cortex were also assessed using immunohistochemistry technique. Our data showed that MJ (10, 20 and 40mg/kg) significantly (p<0.05) reversed LPS-induced memory deficits in mice. The increased brain levels of PGE2, TNFα and IL1β in LPS-treated mice were significantly (p<0.05) reduced by MJ indicating anti-neuroinflammatory activity. MJ also suppressed the expression of COX2, iNOS and NFκB, which further suggest anti-neuroinflammation. The increased brain level of Aβ in LPS-treated mice was significantly (p<0.05) suppressed by MJ suggesting anti-amyloidogenesis-like effect. Our present data showed that MJ attenuated LPS-induced memory dysfunction via mechanisms involving inhibition of pro-inflammatory mediators and beta-amyloid generation in mice.

Abstract
Corylin is a main compound isolated from Psoralea corylifolia L. (Fabaceae). A variety of pharmacological effects such as antioxidant, anti-proliferation, and anti-inflammatory properties of corylin have been reported. Nevertheless, the effect of corylin in microbial infection and sepsis remains unclear. In the present study, we investigated the anti-inflammatory effects of corylin. Our experimental results demonstrated that corylin inhibited the production of TNF-α, IL-6 and NO by both LPS-activated RAW 264.7 cells and LPS-activated murine peritoneal macrophages. Moreover, corylin suppressed the expression levels of iNOS and COX-2, reduced the production of PGE2 and HMGB1, blocked the translocation of HMGB1 from the nucleus to cytosol, and decreased the phosphorylation of MAPKs in LPS-activated RAW 264.7 cells as well as suppressed the activity of NF-κB in LPS-activated J-Blue cells. In addition, the administration of corylin reduced the production of NO and TNF-α, decreased LPS-induced liver damage markers (AST and ALT) and kidney damage markers (BUN and CRE), attenuated infiltration of inflammatory cells and tissue damage of lung, liver and kidney, and enhanced the survival rate of LPS-challenged mice. Taken together, these results show the anti-inflammatory properties of corylin on LPS-induced inflammation and sepsis. Corylin could potentially be a novel anti-inflammatory and immunosuppressive drug candidate in the treatment of sepsis and septic shock.

Abstract
The bulbs of Lilium brownii var. viridulum (LB) are commonly used as both traditional Chinese medicines and popular functional food for many centuries in China. Previous studies reported that the extract of lily bulbs exhibited anti-inflammatory activity both in vivo and in vitro, but its active components and associated molecular mechanisms remain elusive. In the present study, using bioassay-guided isolation method, two phenylpropenoid acylglycerols, 1-O-feruloyl-2-O-p-coumaroylglycerol (1) and 1,3-O-diferuloylglycerol (2), were obtained and identified from the chloroform fraction of LB. Both compounds 1 and 2 significantly decreased the production of nitrite oxide (NO) in lipopolysaccharide (LPS)-stimulated mouse macrophage RAW264.7 cells in a dose-dependent manner with half maximal inhibitory concentration (IC50) values of 9.12 ± 0.72 μM and 12.01 ± 1.07 μM, respectively. They also inhibited the production of prostaglandin E2 (PGE2) and several other pro-inflammatory cytokines, such as interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α). Furthermore, compounds 1 and 2 downregulated the protein levels of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). They also inhibited the nuclear translocation of nuclear factor-κB (NF-κB) p65 subunit and suppressed mitogen-activated protein kinases (MAPKs) pathway. Taken these data together, compounds 1 and 2 exhibited anti-inflammatory activities through acting on the NF-κB and MAPKs pathway. This research provides the first evidence on the major bioactive constituents and related molecular mechanisms of LB as an anti-inflammatory agent. Our findings also advanced the understanding of LB as a traditional herbal medicine for the prevention and treatment of inflammation.

Abstract
Hesperetin (Hesp), a common flavanone glycoside, was extracted from the fruit peel of Citrus aurantium L. (Rutaceae). Hesp has been shown to possess various biological properties, including antioxidant, neuroprotective, and anti-inflammatory properties. In this study, we investigated the protective effect of Hesp on inflammatory responses in lipopolysaccharide (LPS)-induced RAW 264.7 cells. Our results indicated that Hesp treatment dramatically suppressed secretion of tumor necrosis factor (TNF)-α, interleukin (IL)-6, and IL-1β; reduced inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) gene expression; inhibited NF-κB (p65) phosphorylation; and blocked IκBα phosphorylation and degradation. Further studies revealed Hesp markedly enhanced the heme oxygenase (HO)-1 and nuclear factor erythroid 2-related factor 2 (Nrf2) expression, which were involved with inducing Nrf2 nuclear translocation and decreasing Keap1 protein expression. Together, these results indicated that the anti-inflammatory effect of Hesp may be associated with NF-κB inhibition and Nrf2/HO-1 activation.

Abstract
Abundant natural flavonoids can induce nuclear factor-erythroid 2 related factor 2 (Nrf2) and/or AMP-activated protein kinase (AMPK) activation, which play crucial roles in the amelioration of various inflammation- and oxidative stress-induced diseases, including acute lung injury (ALI). Xanthohumol (Xn), a principal prenylflavonoid, possesses anti-inflammation and anti-oxidant activities. However, whether Xn could protect from LPS-induced ALI through inducing AMPK/Nrf2 activation and its downstream signals, are still poorly elucidated. Accordingly, we focused on exploring the protective effect of Xn in the context of ALI and the involvement of underlying molecular mechanisms. Our findings indicated that Xn effectively alleviated lung injury by reduction of lung W/D ratio and protein levels, neutrophil infiltration, MDA and MPO formation, and SOD and GSH depletion. Meanwhile, Xn significantly lessened histopathological changes, reactive oxygen species (ROS) generation, several cytokines secretion, and iNOS and HMGB1 expression, and inhibited Txnip/NLRP3 inflammasome and NF-κB signaling pathway activation. Additionally, Xn evidently decreased t-BHP-stimulated cell apoptosis, ROS generation and GSH depletion but increased various anti-oxidative enzymes expression regulated by Keap1-Nrf2/ARE activation, which may be associated with AMPK and GSK3β phosphorylation. However, Xn-mediated inflammatory cytokines and ROS production, histopathological changes, Txnip/NLRP3 inflammasome and NF-κB signaling pathway in WT mice were remarkably abrogated in Nrf2-/- mice. Our experimental results firstly provided a support that Xn effectively protected LPS-induced ALI against oxidative stress and inflammation damage which are largely dependent upon upregulation of the Nrf2 pathway via activation of AMPK/GSK3β, thereby suppressing LPS-activated Txnip/NLRP3 inflammasome and NF-κB signaling pathway. Xn protects LPS-induced acute lung injury via anti-inflammation and anti-oxidant. Xn induces expressions of GCLC, GCLM, HO-1, NQO-1 and Trx-1. Xn blocks NF-κB and Txnip/NLRP3 inflammasome activation. Xn upregulates AMPK/GSK3β-Nrf2 signal axis. Xn-attenuated acute lung injury is effectively abrogated in Nrf2-/- mice.

A novel indication of platonin, a therapeutic immunomodulating medicine, on neuroprotection against ischemic stroke in mice. Sci Rep 2017; 7:42277.

Abstract
Thrombosis and stroke are major causes of disability and death worldwide. However, the regular antithrombotic drugs may have unsatisfactory results and side effects. Platonin, a cyanine photosensitizing dye, has been used to treat trauma, ulcers and some acute inflammation. Here, we explored the neuroprotective effects of platonin against middle cerebral artery occlusion (MCAO)-induced ischemic stroke in mice. Platonin(200 μg/kg) substantially reduced cerebral infarct volume, brain edema, neuronal cell death and neurological deficit scores, and improved the MCAO-reduced locomotor activity and rotarod performance. Platonin(5–10 μM) potently inhibited platelet aggregation and c-Jun NH2-terminal kinase (JNK) phosphorylation in collagen-activated platelets. The antiaggregation effect did not affect bleeding time but increased occlusion time in platonin(100 and 200 μg/kg)-treated mice. Platonin(2–10 μM) was potent in diminishing collagen- and Fenton reaction-induced ∙OH formation. Platonin(5–10 μM) also suppressed the expression of nitric oxide, inducible nitric oxide synthase, cyclooxygenase-2, interleukin-1β, and JNK phosphorylation in lipopolysaccharide-stimulated macrophages. MCAO-induced expression of 3-nitrotyrosine and Iba1 was apparently attenuated in platonin(200 μg/kg)-treated mice. In conclusion, platonin exhibited remarkable neuroprotective properties against MCAO-induced ischemia in a mouse model through its antiaggregation, antiinflammatory and antiradical properties. The observed therapeutic efficacy of platonin may consider being a novel medcine against ischemic stroke.

Anti-inflammatory effect of the six compounds isolated from Nauclea officinalis Pierrc ex Pitard, and molecular mechanism of strictosamide via suppressing the NF-κB and MAPK signaling pathway in LPS-induced RAW 264.7 macrophages. JOURNAL OF ETHNOPHARMACOLOGY 2017; 196:66-74. [PMID: 27989509 DOI: 10.1016/j.jep.2016.12.007] [Citation(s) in RCA: 39] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/25/2016] [Revised: 12/05/2016] [Accepted: 12/07/2016] [Indexed: 06/06/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Nauclea officinalis Pierrc ex Pitard. is a Chinese medicinal herb that contains high level of alkaloids which is the most abundant and active constituent. Strictosamide isolated from Nauclea officinalis Pierrc ex Pitard. showed significant effects on inflammatory response, compared with pumiloside, 3-epi-pumiloside, vincosamide, 3α,5α-tetrahydrodeoxycordifoline lactam and naucleamide A-10-O-β-D-glucopyranoside of this plant. AIM OF STUDY we investigated the biological activities of the six compounds mentioned-above, and the underlying molecular mechanism exerted by the most potent one, strictosamide. MATERIALS AND METHODS The effects of strictosamide and other five compounds on the inhibitory activity of nitric oxide (NO) were screened by Griess test. The contents of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in media were detected by using Enzyme-linked immunosorbent (ELISA) kits. The effects on the mRNA expression of nitric oxide synthase (iNOS), TNF-α and IL-1β of strictosamide were further investigated by RT-qPCR. Western blot assay was conducted to illustrate the effects of strictosamide on iNOS and phosphorylation of p65, inhibitor of NF-κB (IκB)-α, IκB-kinase (IKK)-α as well as p-extracellular signal-regulated kinase (ERK), p-c-jun N-terminal kinase (JNK) and p-p38 in the protein levels. RESULTS Strictosamide potently suppressed the productions of NO, TNF-α and IL-1β in LPS-induced RAW 264.7 macrophages, and it dose-dependently alleviated the LPS-simulated protein level of iNOS as well as the mRNA expressions of iNOS, TNF-α and IL-1β. In addition, molecular data revealed that strictosamide markedly decreased the expressions of p-p65, p-IκBα and p-IKKα. Furthermore, strictosamide significantly attenuated LPS-induced the phosphorylation of p38, ERK and JNK. CONCLUSIONS At present study, the results indicated that the anti-inflammatory activity of strictosamide was associated with the restraint of NO, TNF-α and IL-1β via negative regulation of both NF-κB and mitogen-activated protein kinases (MAPKs) in LPS-induced RAW 264.7 cells.

Abstract
Lipopolysaccharides (LPS) strongly stimulate immune cells, and unabated activation of immune system by LPS may lead to an exacerbation of sickness and depression. In this study, stigmasta-3,5-dien-7-one (ST) was isolated from Phragmitis rhizoma as a negative regulator of LPS-induced inflammation in macrophages. ST effectively reduced nitric oxide (NO), prostaglandin E2, and pro-inflammatory cytokine levels, which were markedly raised by LPS treatment. In addition, ST blocked the nuclear factor-kappa B (NF-κB) signaling pathway via down-regulation of phospho-p38 mitogen-activated protein kinase and phosphorylation and degradation of the inhibitor of NF-κB α. To our knowledge, this is the first study showing anti-inflammatory activities of ST isolated from Phragmitis rhizoma.

Abstract
Turmeric or Curcuma is a natural product that has anti-inflammatory, antioxidant and anti-apoptotic pharmacological properties. It can be used in the control of the aging process that involves oxidative stress, inflammation, and apoptosis. Aging is a physiological process that affects higher cortical and cognitive functions with a reduction in learning and memory, limited judgment and deficits in emotional control and social behavior. Moreover, aging is a major risk factor for the appearance of several disorders such as cerebrovascular disease, diabetes mellitus, and hypertension. At the brain level, the aging process alters the synaptic intercommunication by a reduction in the dendritic arbor as well as the number of the dendritic spine in the pyramidal neurons of the prefrontal cortex, hippocampus and basolateral amygdala, consequently reducing the size of these regions. The present review discusses the synaptic changes caused by the aging process and the neuroprotective role the Curcuma has through its anti-inflammatory, antioxidant and anti-apoptotic actions

Abstract
Whey proteins provide structure and nutritional properties in food, while berry juices are thought to have biological activity that can impart anti-inflammatory health effects. In combination, the two could be an excellent source of necessary and supplemental nutrients as well as expand the functionality of whey proteins in food structures. The objectives of this investigation were to (1) develop an approach for particle formation between whey protein and cranberry, blackcurrant, or muscadine grape juices, (2) determine resulting particle composition and physical characteristics, and (3) evaluate properties related to food structure stability and maintenance of phytochemical bioactivity. Particles were formed by combining 20% w/w whey protein with juice containing 50, 250, or 500 μg g(-1) total phenolics, adjusting pH to 4.5, and centrifuging to collect aggregated particles. Particles had an approximate molar ratio of 9-50 proteins per polyphenol, and the ratio increased with increasing phenolic content of the juice used to create the particles. Particle size ranged from 1-100 μm at pH 4.5, compared to 10 μm particles that formed when whey protein isolate alone was precipitated at pH 4.5. Polyphenols and other juice components, such as acids and sugars appeared to be involved in particle formation. Particles improved foam stability, and the anti-inflammatory properties of entrapped polyphenols were maintained in the particles. Highly functional protein-polyphenol particles can be designed to stabilize food structures and simultaneously deliver polyphenols associated with health benefits.

Abstract
The chemical components and biological activity of Camellia mistletoe, Korthalsella japonica (Loranthaceae) are relatively unknown compared to other mistletoe species. Therefore, we investigated the phytochemical properties and biological activity of this parasitic plant to provide essential preliminary scientific evidence to support and encourage its further pharmaceutical research and development. The major plant components were chromatographically isolated using high-performance liquid chromatography and their structures were elucidated using tandem mass spectrometry and nuclear magnetic resonance anlysis. Furthermore, the anti-inflammatory activity of the 70% ethanol extract of K. japonica (KJ) and its isolated components was evaluated using a nitric oxide (NO) assay and western blot analysis for inducible NO synthase (iNOS) and cyclooxygenase (COX)-2. Three flavone di-C-glycosides, lucenin-2, vicenin-2, and stellarin-2 were identified as major components of KJ, for the first time. KJ significantly inhibited NO production and reduced iNOS and COX-2 expression in lipopolysaccharide-stimulated RAW 264.7 cells at 100 µg/ mL while similar activity were observed with isolated flavone C-glycosides. In conclusion, KJ has a simple secondary metabolite profiles including flavone di-C-glycosides as major components and has a strong potential for further research and development as a source of therapeutic anti-inflammatory agents.

Abstract
Tenuigenin (TNG), isolated from the root of the Chinese herb Polygala tenuifolia, possesses various biological and pharmacological activities, including anti-oxidation and anti-inflammation activities. In this study, we aimed to further investigate whether its anti-inflammatory activity is associated with the inhibition of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression in lipopolysaccharide (LPS)-induced RAW 264.7 cells. Our results showed that TNG treatment dramatically reduced prostaglandin E2 (PGE2) and NO production, decreased iNOS and COX-2 gene expression, inhibited JNK1/2, ERK1/2, p38 and NF-κB (p65) phosphorylation, and blocked IκBα phosphorylation and degradation. Further studies revealed that TNG dramatically up-regulated heme oxygenase (HO)-1 and nuclear factor erythroid 2-related factor 2 (Nrf2) expression, which was related to the induction of Nrf2 nuclear translocation and decreased Keap1 protein expression. Additionally, treatment with JNK1/2, ERK1/2 or p38 inhibitors had no effect on the TNG-induced HO-1 protein expression. Furthermore, the LPS-induced iNOS and COX-2 expression levels were inhibited by TNG, which was partially reversed by the HO-1-siRNA and HO-1 inhibitors. Together, these results showed that TNG's anti-inflammatory activity is related to the inhibition of iNOS and COX-2 expression via down-regulation of the MAPK and NF-κB, and up-regulation of the Nrf2/HO-1 signaling pathways.

Abstract
The present study investigated the protective effect of Pyropia yezoensis glycoprotein (PYGP) against chronic ethanol consumption‑mediated hepatotoxicity in rats. Male Sprague-Dawley rats (n=20; 6 weeks old) were randomly divided into four groups. The rats in each group were treated for 30 days with the following: i) CON group, distilled water only; ii) EtOH group, 20% ethanol 3.7 g/kg/BW; iii) EtOH+150 group, 20% ethanol 3.7 g/kg/BW+PYGP 150 mg/kg/BW; iv) EtOH+300 group, 20% ethanol 3.7 g/kg/BW+PYGP 300 mg/kg/BW. EtOH, PYGP and water were orally administered. The rats were sacrificed after 30 days, and blood and liver samples were collected for analysis. Treatment with ethanol caused significant elevation of serum levels of glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT). Furthermore, inhibition of the antioxidant defense system in the liver, including glutathione (GSH), glutathione peroxidase (GSH‑px) and catalase (CAT) was observed. However, co‑administration with PYGP recovered the antioxidant defense system, and the serum levels of GOT and GPT. PYGP was shown to attenuate ethanol toxicity via the inactivation of mitogen‑activated protein kinases (MAKPs). PYGP suppressed the overexpression of cytochrome P450 2E1 (CYP2E1), inducible nitric oxide synthase and cyclooxygenase‑2. These results suggested that the protective effect of PYGP was associated with antioxidant activities, MAPKs and the CYP2E1 signaling pathway.

Abstract
Crebanine, an aporphine alkaloid, displays various biological activities such as anticancer and antimicrobial activities. In this study, we further investigated the suppressive effect of crebanine on lipopolysaccharide (LPS)-induced expression of proinflammatory mediators and the molecular mechanisms underlying these activities in RAW264.7 macrophages. Crebanine inhibited the production of proinflammatory cytokines including interleukin-6 (IL-6) and tumor necrosis factor-alpha in LPS-induced RAW264.7 cells. Moreover, crebanine suppressed LPS-induced inducible nitric oxide (iNO) and prostaglandin E2 and reduced the expression of iNO synthase and cyclooxygenase-2 in RAW264.7 cells. Crebanine suppressed LPS-induced phosphorylation of Akt and mitogen-activated protein kinases (MAPKs), including extracellular signaling-regulated kinase 1/2, c-Jun NH2-terminal kinase, and p38 MAPK signaling. In addition, the specific inhibitor of MAPKs and Akt reduced the expression of IL-6 and NO production in LPS-induced macrophages. Furthermore, crebanine inhibited LPS-induced nuclear factor kappa B (NF-κB) activation by reducing the phosphorylation of p65 at Ser536 but not the p65 translocation to the nucleus and inhibitory factor kappa B alpha degradation. Crebanine also suppressed phosphorylation and nucleus translocation of activator protein-1 (AP-1). These observations suggest that the antiinflammatory properties of crebanine may stem from the inhibition of proinflammatory mediators via suppression of the NF-κB, AP-1, MAPKs, and Akt signaling pathways.

Abstract
Background Immunoregulatory elements have emerged as useful immunotherapeutic agents against cancer. In traditional medicine, Mori folium, the leaf of Morus alba L. (Moraceae), has been used for various medicinal purposes; however, the immunomodulatory effects have not been fully identified. We evaluated the immunoenhancing potential of water extract of Mori folium (WEMF) in murine RAW264.7 macrophages. Methods RAW264.7 cells were treated with WEMF for 24 hours and cell viability was detected by an MTT method. Nitric oxide (NO) levels in the culture supernatants were assayed using Griess reagent. The productions of prostaglandin E2 (PGE2) and immune-related cytokines was measured using ELISA detection kits. The mRNA and protein expression levels of Inducible NO synthase, COX-2, and cytokines were assayed by reverse transcription-PCR and Western blotting, respectively. The effect of WEMF on phagocytic activity was measured using a Phagocytosis Assay Kit. Results WEMF significantly stimulated the production of NO and PGE2 as immune response parameters at noncytotoxic concentrations, which was associated with the increased expression of inducible NO synthase and COX-2. The release and expression of cytokines, such as TNF-α, interleukin (IL)-1β, IL-6, and IL-10, were also significantly increased in response to treatment with WEMF. Moreover, WEMF promoted the macrophagic differentiation of RAW264.7 cells and the resulting phagocytosis activity. Conclusions WEMF has the potential to modulate the immune function by regulating immunological parameters. Further studies are needed to identify the active compounds and to support the use of WEMF as an immune stimulant.

Abstract
The implication of inflammatory tissue damage in pathophysiology of human cancer as well as some metabolic disorders has been under intense investigation. Numerous studies have identified a series of critical signaling molecules involved in cellular responses to inflammatory stimuli. These include nuclear factor κB, peroxisome proliferator-activated receptor γ, nuclear factor erythroid 2 p45-related factor 2 and sterol regulatory element-binding protein 1. The proper regulation of these transcription factors mediating pro- and anti-inflammatory signaling hence provides an important strategy for the chemoprevention of inflammation-associated cancer. There is compelling evidence supporting that dietary supplementation with fish oil-derived ω-3 polyunsaturated fatty acids including docosahexaenoic acid (DHA) ameliorates symptomatic inflammation associated with cancer as well as other divergent human disorders. Acute or physiologic inflammation is an essential body's first line of defence to microbial infection and tissue injuries, but it must be properly completed by a process termed 'resolution'. Failure of resolution mechanisms can result in persistence of inflammation, leading to chronic inflammatory conditions and related malignancies. The phagocytic engulfment of apoptotic neutrophils and clearance of their potentially histotoxic contents by macrophages, called efferocytosis is an essential component in resolving inflammation. Of note, DHA is a precursor of endogenous proresolving lipid mediators which regulate the leukocyte trafficking and recruitment and thereby facilitate efferocytosis. Therefore, DHA and its metabolites may have a preventive potential in the management of human cancer which arises as a consequence of impaired resolution of inflammation as well as chronic inflammation.

Abstract
Exposure to particulate matter (PM), a major form of air pollution, can induce oxidative stress and inflammation and may lead to many diseases in various organ systems including the skin. Eupafolin, a flavonoid compound derived from Phyla nodiflora, has been previously shown to exhibit various pharmacological activities, including antioxidant and anti-inflammatory effects. Unfortunately, eupafolin is characterized by poor water solubility and skin penetration, which limits its clinical applications. To address these issues, we successfully synthesized a eupafolin nanoparticle delivery system (ENDS). Our findings showed that ENDS could overcome the physicochemical drawbacks of raw eupafolin with respect to water solubility and skin penetration, through reduction of particle size and formation of an amorphous state with hydrogen bonding. Moreover, ENDS was superior to raw eupafolin in attenuating PM-induced oxidative stress and inflammation in HaCaT keratinocytes, by mediating the antioxidant pathway (decreased reactive oxygen species production and nicotinamide adenine dinucleotide phosphate oxidase activity) and anti-inflammation pathway (decreased cyclooxygenase-2 expression and prostaglandin E2 production through downregulation of mitogen-activated protein kinase and nuclear factor-κB signaling). In summary, ENDS shows better antioxidant and anti-inflammatory activities than raw eupafolin through improvement of water solubility and skin penetration. Therefore, ENDS may potentially be used as a medicinal drug and/or cosmeceutical product to prevent PM-induced skin inflammation.

Abstract
3D pharmacophore modeling has evolved as an established and state-of-the-art method for performing in-silico predictions of biological activity. Using one single model is limited to single binding modes, while the combination of several models bears a broader application scope. We demonstrate the generation of a complete and predictive 3D model set for cyclooxygenase 1 and 2 inhibitors, along with a selection and validation protocol optimized for parallel virtual screening. This model set was applied to explain the cyclooxygenase activity of an ethnopharmacologically known mixture of natural products, the Thai traditional medicine "Prasaplai". Results show that rationalizing natural product activity by modern in-silico approaches is promising and can be tremendously useful in the identification of the mechanisms of action for known biological effects of complex herbal remedies.

Abstract
AIMS Present emerging world is emphasizing the implication of vitamin D deficiency associated with development of inflammation and neurodegenerative disorder like Alzheimer's disease (AD). The chief neuropathological hallmark of AD is aggregation of amyloid-beta (Aβ) peptides surrounding microglial cells in human brain. Microglial activation plays a key role in inflammatory response and neuronal injury. Naturally abundant vitamin D2 (VD2) exhibiting anti-inflammatory activities are yet to explore more. This study has investigated the inhibitory effect of VD2 on inflammatory activities of BV2 microglial cells. MAIN METHODS Cellular compatibility of VD2 and Aβ25-35 protein in treated BV2 microglial cells were measured by CCK-8 assay. Induction of iNOS, COX-2 and NF-κB signaling cascade were measured by western blotting, whereas pro-inflammatory cytokines were measured by ELISA. In addition, generation of ROS was detected by fluorescence intensity. KEY FINDINGS Morphological observations showed that Aβ25-35 induced BV2 cells stimulation noticeably got reduced in VD2 pre-treated group at 24h time period. Anti-inflammatory activities of VD2 was observed demonstrating the inhibition of up-regulated iNOS and COX-2 protein expression further confirmed by attenuating the activated microglia released pro-inflammatory cytokines IL-1β, IL-6, TNF- α and ROS, while blocking the phosphorylation of NF-κB p65 in nucleus by preventing IκB-α degradation and phosphorylation in cytosol. SIGNIFICANCE The present study revealed that VD2 blocked the phosphorylation of NF-κB inflammatory signaling pathway in Aβ25-35 induced activated BV2 microglial cells by suppressing ROS generation and inflammatory cytokines. Our finding suggests that vitamin D2 has therapeutic potential against inflammation and Alzheimer's disease.

Abstract
ETHNOPHARMACOLOGY RELEVANCE Water dropwort [Oenanthe javanica (O. javanica)] is an aquatic perennial herb cultivated in East Asian countries. It has been popularly used in traditional Chinese medicine which is beneficial for the treatment of many diseases, including jaundice and various types of chronic and acute hepatitis. In the present study, we investigated the hepatoprotective effect of total phenolics from O. javanica (TPOJ) against D-galactosamine (D-GalN) induced liver injury in mice. MATERIAL AND METHODS The hepatoprotective activity of TPOJ (125, 250 and 500mg/kg) was investigated on D-GalN (800mg/kg)-induced liver damages in mice. Blood and liver were collected for biochemical and microscopic analysis. RT-PCR was used to determine the changes in hepatic nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression. Protein levels of iNOS, COX-2, superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) were determined by western blotting. RESULTS In the animal studies, TPOJ could improve the survival of acute liver failure model significantly and prevente the D-GalN-induced elevation of the serum enzymatic markers and nonenzymatic markers levels significantly. Meanwhile, TPOJ-treatment decreased the malondialdehyde (MDA) level and elevated the content of glutathione (GSH) in the liver as compared to those in the D-GalN group. Hepatic activities and protein expressions of antioxidative enzymes, including SOD, GPx, and CAT were enhanced dose dependently with TPOJ. At the same time, application of TPOJ effectively suppressed the D-GalN-induced proinflammatory mRNA and protein expression of iNOS and COX-2. Subsequently, the serum levels of proinflammatory mediators, nitric oxide (NO) and prostaglandin E2 (PGE2) were reduced. Additionally, histological analyses also showed that TPOJ reduced the extent of liver lesions induced by D-GalN. CONCLUSION Our investigation demonstrated the hepatoprotective activity of TPOJ and revealed that TPOJ attributed its significance in the traditional use for treating liver diseases.

Abstract
The nutritional prevention of aberrant crypt foci by polyphenols may be a crucial step to dietary cancer prevention. The objective of this study was to determine the underlying mechanisms that contribute to the anti-inflammatory and antitumorigenic properties of plum (Prunus salicina L.) polyphenols, including chlorogenic acid and neochlorogenic acid, in azoxymethane (AOM)-treated rats. The hypothesis was that plum polyphenolics suppress AOM-induced aberrant crypt foci formation through alterations in the protein kinase B (AKT)/mammalian target of rapamycin (mTOR) pathway and relative micro-RNA expressions. Sprague-Dawley rats (n=10/group) received plum beverage (1346mg gallic acid equivalents/L) or a control beverage ad libitum for 10 weeks with subcutaneous injections of AOM (15mg/kg) at weeks 2 and 3. Results show that the consumption of the plum beverage decreased the number of dysplastic aberrant crypt foci by 48% (P<.05) and lowered proliferation of mucosal cells by 24% (P<.05). The plum beverage decreased the activity of glutathione peroxidase, superoxide dismutase, and catalase in mucosal scrapings, as well as the superoxide dismutase activity in serum. The results were accompanied by a down-regulation of proinflammatory enzymes nuclear factor κB, nitric oxide synthase, cyclooxygenase-2, and vascular cell adhesion molecule 1 messenger RNA. Plum inhibited the expression of AKT and mTOR messenger RNA, phosphorylated AKT, mTOR, and hypoxia-inducible factor-1α protein levels, and the ratio of the phosphorylated/total protein expression of mTOR. Also, the plum beverage increased the expression of miR-143, which is involved in the regulation of AKT. These results suggest that plum polyphenols may exhibit a chemopreventive potential against colon carcinogenesis by impacting the AKT/mTOR pathway and miR-143.

Abstract
Bioactive components such as polyphenols, present in many plants, are purported to have anti-inflammatory and antiangiogenic properties. Date syrup, produced from date fruit of the date palm tree, has traditionally been used to treat a wide range of diseases with etiologies involving angiogenesis and inflammation. It was hypothesized that polyphenols in date syrup reduce angiogenic responses such as cell migration, tube formation, and matrix metalloproteinase activity in an inflammatory model by exhibiting anti-inflammatory activity mediated by vascular endothelial growth factor (VEGF) and the prostaglandin enzyme cyclooxygenase-2 (COX-2) in endothelial cells. Date syrup polyphenols at 60 and 600μg/mL reduced inflammation and suppressed several stages of angiogenesis, including endothelial cell migration, invasion, matrix metalloproteinase activity, and tube formation, without evidence of cytotoxicity. VEGF and COX-2 expression induced by tumor necrosis factor-alpha at both gene expression and protein level was significantly reduced by date syrup polyphenols in comparison to untreated cells. In conclusion, polyphenols in date syrup attenuated angiogenic responses and exhibited anti-inflammatory activity mediated by VEGF and COX-2 expression in endothelial cells.

Abstract
The purpose of this study was to evaluate the effects of polydatin (PD) on cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) expressions at protein and transcriptional levels, as well as the production of prostaglandin E2 (PGE2) and nitric oxide (NO) in lipopolysaccharide (LPS)-induced macrophage RAW 264.7 cells. To elucidate the underlying mechanism responsible for these symptoms, we investigated the phosphorylation of mitogen-activated protein kinase (MAPK) pathway and nuclear factor-κB (NF-κB) expression. NO was analyzed with the Griess method. PGE2 was measured by enzyme-linked immunosorbent assay (ELISA). iNOS and COX-2 messenger RNA (mRNA) were identified by qPCR assay. iNOS, COX-2, NF-κB, extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK) and p38 protein expressions were detected with Western blot. The results revealed that PD effectively inhibited NO and PGE2 production, and it is not surprising that PD reduced iNOS and COX-2 expression at protein and transcriptional levels. Additionally, PD significantly ameliorated the activation of NF-κB and the phosphorylation of MAPKs in LPS-induced RAW 264.7 macrophages. These findings suggested that PD exerted potent anti-inflammatory activity in macrophages.

Anti-inflammatory function of 4-tert-butylphenyl salicylate through down-regulation of the NF-kappa B pathway. Arch Pharm Res 2016; 39:429-36. [PMID: 26849878 DOI: 10.1007/s12272-015-0679-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2014] [Accepted: 11/04/2015] [Indexed: 10/22/2022]
Abstract
The salicylic acid derivative 4-tert-butylphenyl salicylate (4-TBPS) possesses anti-inflammatory activity. We demonstrated this and elucidated the mechanisms involved by using the lipopolysaccharide-stimulated Raw 264.7 mouse macrophage model. The 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, western blot, enzyme-linked immunosorbent assay, and reverse transcriptase-polymerase chain reaction were performed to explore 4-TBPS anti-inflammatory activity. We found that 4-TBPS decreased nitric oxide production without cytotoxic effects on macrophages and reduced expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 in a dose-dependent manner. Additionally, mRNA expressions of iNOS and COX-2 significantly reduced, with concentrations between 1 and 15 µg/ml. Furthermore, 4-TBPS significantly inhibited the production of pro-inflammatory cytokines including tumor necrosis factor-α (TNF-α), interleukin- (IL)-1β, and IL-6. Moreover, mRNA gene expression of TNF-α, IL-1β, and IL-6 was attenuated in a dose-dependent manner. 4-TBPS potently inhibited translocation of nuclear factor-κB (NF-κB) into the nucleus by degrading IκB kinase (IκBα) following its phosphorylation, thereby causing NF-κB to remain inactive. Collectively, our data indicate that 4-TBPS significantly (p < 0.01) targets the inflammatory response of macrophages via inhibition of iNOS, COX-2, TNF-α, IL-1β, and IL-6 through downregulation of the NF-κB pathway. This indicates that 4-TBPS may have therapeutic potential in inflammatory disorders.

Flavonoids of Polygonum hydropiper L. attenuates lipopolysaccharide-induced inflammatory injury via suppressing phosphorylation in MAPKs pathways. BMC COMPLEMENTARY AND ALTERNATIVE MEDICINE 2016; 16:25. [PMID: 26801102 PMCID: PMC4724128 DOI: 10.1186/s12906-016-1001-8] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/09/2015] [Accepted: 01/12/2016] [Indexed: 11/30/2022]
Abstract
Background Polygonum hydropiper L. is widely used as a traditional remedy for the treatment of dysentery, gastroenteritis. It has been used to relieve swelling and pain, dispel wind and remove dampness, eliminate abundant phlegm and inflammatory for a long time. Previous study showed that antioxidants especially flavonoids pretreatment alleviated sepsis-induced injury in vitro and in vivo. In the present study, the possible anti-inflammatory effect of flavonoids from normal butanol fraction of Polygonum hydropiper L. extract (FNP) against inflammation induced by lipopolysaccharide (LPS) was evaluated in vivo and in vitro. Methods The content of total flavonoid of FNP was determined by the aluminum colorimetric method. The content of rutin, quercetin and quercitrin was determined by HPLC method. Mice received FNP orally 3 days before an intra-peritoneal (i.p.) injection of lipopolysaccharide (LPS). Total superoxidase dismutase (T-SOD), total antioxidant capacity (T-AOC), glutathione peroxidase (GSH-PX), glutathione (GSH), myeloperoxidase (MPO) and malondialdehyde (MDA) levels were measured. Tumor necrosis factor-α levels in serum and tissue was measured. mRNA expressions of pro-inflammatory cytokines in lung were assessed by Real-Time PCR. Histopathological changes were evaluated in lung, ileum and colon. We also investigated FNP on reactive oxygen species (ROS), nitric oxide (NO) and pro-inflammatory cytokines (TNF-α, IL-1β, IL-6 and IL-8) production, inducible nitric oxide synthase (iNOS), Cyclooxygenase-2 (COX-2) protein expression, phosphorylation of MAPKs and AMPK in LPS-stimulated RAW264.7 cells. Results FNP increased the levels of T-SOD, T-AOC, GSH-PX and GSH, decreased the levels of TNF-α, MPO and MDA, attenuate the histopathological lesion in LPS-stimulated mice. FNP inhibited production of inflammatory cytokines, ROS and NO, protein expressions of iNOS and COX-2, phosphorylation of ERK, JNK and c-JUN in MAPKs, promoted phosphorylation of AMPKα suppressed by LPS. Conclusion These results suggested in vivo anti-inflammatory activities of FNP might contributed to its enhancement in antioxidant capacity, its inhibitory effects may be mediated by inhibiting the phosphorylation of JNK, ERK and c-JUN in MAPKs signaling pathways.
