In this study, we investigated the microbial community and its correlation with anti-inflammatory effects during the fermentation procedure of shindari. Since shindari is traditionally manufactured through a fermentation process of 3–4 days in summer or 5–6 days in winter, the shindari materials applied in this study were fermented for 1, 3, and 5 days, respectively. Microbial community structure in the shindari manufacturing process was analyzed by Illumina MiSeq sequencing. Results revealed different fermentation time had different influences on the community structure and microbial diversity in the shindari process. Ultimately, we found that pathogenic bacteria such as Enterococcus durans (9.3%) and Enterobacter asburiae (4.5%) dominate the shindari fermented for 1 day, while samples with a fermentation period of more than 3 days occupied lactic acid bacteria such as Pediococcus sp. (97.1%). In addition, to study the relationship between fermentation period and anti-inflammatory effect in the shindari manufacturing process, we applied RAW264.7 cells, a classic cell model for inflammation studies. First, we prepared an ethyl acetate extract of shindari fermented for 1 (S1), 3 (S3), or 5 days (S5), and then it was confirmed that all of these extracts inhibited the nitric oxide (NO) production in a concentration-dependent manner. In addition, these inhibitory effects were correlated with the suppressive effect of shindari extracts against overexpression of inducible nitric oxide synthase (iNOS). Furthermore, S3 and S5 also inhibited the production of pro-inflammatory cytokines such as tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and IL-6. Overall, the anti-inflammatory effect of S3 was suggested to be mediated through the negative regulation of mitogen-activated protein kinase signaling (MAPKs) and nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) signaling pathways.

Inflammatory Effect

Artemisia anomalaS. Moore has been widely used in China to treat inflammatory diseases for hundreds of years. However, mechanisms associated with its anti-inflammatory effect are not clear. In this study, we prepared ethyl acetate, petroleum ether,n-BuOH, and aqueous extracts from ethanol extract ofArtemisia anomalaS. Moore. Comparing anti-inflammatory effects of these extracts, we found that ethyl acetate extract of this herb (EAFA) exhibited the strongest inhibitory effect on nitric oxide (NO) production in LPS/IFNγ-stimulated RAW264.7 cells. EAFA suppressed the production of NO in a time- and dose-dependent manner without eliciting cytotoxicity to RAW264.7 cells. To understand the molecular mechanism underlying EAFA’s anti-inflammatory effect, we showed that EAFA increased total cellular anti-oxidant capacity while reducing the amount of inducible nitric oxide synthase (iNOS) in stimulated RAW264.7 cells. EAFA also suppressed the expression of IL-1βand IL-6, whereas it elevates the level of heme oxygenase-1. These EAFA-induced events were apparently associated with NF-κB and MAPK signaling pathways because the DNA binding activity of p50/p65 was impaired and the activities of both ERK and JNK were decreased in EFEA-treated cells comparing to untreated cells. Our findings suggest that EAFA exerts its anti-inflammatory effect by inhibiting the expression of iNOS.

Introduction: Annona senegalensis Pers (Annonaceae) and Piliostigma thonningii (Schum.) (Leguminoseae)  are two medicinal plants used, often in combination, in traditional Togolese medicine for the treatment of diseases with an inflammatory component. Objective: The aim of this study is to evaluate the anti-inflammatory effect of the hydro-ethanolic extract (EHEM) of the combination of A. senegalensis and P. thonningii (1: 1, m: m). Methods: The ovalbumin-induced allergic airway asthma model was used. Animals made asthmatic were treated with EHEM at doses of 250 and 500 mg / kg. Inflammation markers including histamine, nitric oxide (NO), vascular leakage, leukocyte infiltration in the airways, and malondialdehyde (MDA), were measured. Results: Compared to the SNT group, EHEM inhibits the infiltration of the airways by leukocytes (850,00 × 103 ± 50 cells / mL vs 1830 × 103 ± 53,85 cells / mL for ST500 mg / kg, P <0,05). It inhibited vascular permeability to Evans Blue (10,40 ± 0,270 μg / mL vs ST500, p<0,05). It inhibited histamine release (13,95 ± 0,937 μg / mL vs 32,78 ± 1,044 μg / mL, p<0,05) and NO production (0,211 ± 0,008 Μm vs 0,315 ± 0,022 μM, p<0,05). It finally inhibited MDA production (14,66 ± 0,533 nM / mL vs 9,014 ± 0,366 nM / mL and 7,149 ± 0,300 nM / mL, p<0,05) in lung tissue. Conclusion: Our results suggest that EHEM inhibits OVA-induced inflammation. These results justify the use of this combination of plants in traditional Togolese medicine. Keywords: Inflammation, malondialdehyde, Annona senegalensis, Piliostigma thonningii.

Lilium bulbs have long been used as Chinese traditional medicines to alleviate the symptoms of various human inflammatory diseases. However, mechanisms of Lilium bulb-mediated anti-inflammatory activity and the bioactive components in Lilium bulbs remain unknown. In the present study, the anti-inflammatory activity of Lilium bulbs and the underlying mechanism of action were investigated in macrophages using Lilium bulb ethanol extracts (Lb-EE). In a dose-dependent manner, Lb-EE inhibited nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW264.7 cells and bone marrow-derived macrophages (BMDMs) without causing significant cytotoxicity. Lb-EE also down-regulated mRNA expression of inflammatory genes in LPS-stimulated RAW264.7 cells, which included inducuble nitric oxide synthase (iNOS), cyclooxygenase-2 (COX2), and tumor necrosis factor-[Formula: see text] (TNF-[Formula: see text]). Furthermore, Lb-EE markedly restored LPS-induced morphological changes in RAW264.7 cells to a normal morphology. HPLC analysis identified quercetin, luteolin, and kaempferol as bioactive components contained in Lb-EE. Mechanistic studies in LPS-stimulated RAW264.7 cells revealed that Lb-EE suppressed MyD88- and TRIF-induced NF-[Formula: see text]B transcriptional activation and the nuclear translocation of NF-[Formula: see text]B transcription factors. Moreover, Lb-EE inhibited IKK[Formula: see text]/[Formula: see text]-induced activation of the NF-[Formula: see text]B signaling pathway and IKK inhibition significantly reduced NO production in LPS-stimulated RAW264.7 cells. Taken together, these results suggest that Lb-EE plays an anti-inflammatory role by targeting IKK[Formula: see text]/[Formula: see text]-mediated activation of the NF-[Formula: see text]B signaling pathway during macrophage-mediated inflammatory responses.

 Objective: The aim of this study was to investigate in vitro anti-inflammatory activity of tinocrisposide using lipopolysaccharides (LPS)-stimulated RAW 264.7 macrophage cells. Tinocrisposide is a furano diterpene glycoside that was isolated in our previous study from Tinospora crispa.Methods: Anti-inflammatory effect was quantified spectrometrically using Griess method by measuring nitric oxide (NO) production after the addition of Griess reagent.Results: The sample concentrations of 1, 5, 25, 50, and 100 μM and 100 μM of dexamethasone (positive control) have been tested against the LPS-stimulated RAW 264.7 cells, and the results showed NO level production of 39.23, 34.00, 28.9, 20.25, 16.3, and 13.68 μM, respectively, and the inhibition level of 22.67, 33.00, 43.03, 60.10, 68.00, and 73%, respectively.Conclusions: From the study, it could be concluded that tinocrisposide was able to inhibit the formation of NO in the LPS-stimulated RAW 264.7 cells in concentration activity-dependent manner, with half-maximal inhibition concentration 46.92 μM. It can be developed as anti-inflammatory candidate drug because NO is a reactive nitrogen species which is produced by NO synthase. The production of NO has been established as a mediator in inflammatory diseases.

Objective: The objective of the present study is to determine the anti-inflammatory effect of a partially purified lectin from phloem exudates againstpaw edema mice model.Methods: Partially purified lectin was prepared by phloem exudates in phosphate buffer saline followed by ammonium sulfate precipitation anddialysis. Anti-inflammatory activity was determined against carrageenan-induced mice model and inhibition of nitric oxide (NO) production wasdetermined.Results: Partially purified lectin exhibited promising anti-inflammatory activity at 50 mg/kg b.w. by reducing the edema volume significantly up to64% (**p<0.01) against control mice. Decrease in myeloperoxidase activity and NO production in paw exudates was observed up to 55.90 (*p<0.05)and 47.22% (*p<0.05), respectively, and this supports the anti-inflammatory property of the partially purified lectin.Conclusion: This finding indicated that further studies needed to purify and characterize a novel lectin from Praecitrullus fistulosus for elucidating themolecular mechanism of anti-inflammatory activity.

Juglans mandshurica Maxim., a traditional folk medicinal plant, is widely distributed in Korea and China. In our previous study, we isolated a new phenylpropanoid compound, 4-((1R,2R)-3-hydroxy-1-(4-hydroxyphenyl)-1-methoxypropan-2-yl)-2-methoxyphenol (HHMP), from J. mandshurica. In the present study, we evaluated the anti-inflammatory activity of HHMP on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells and zebrafish larvae. HHMP significantly inhibited LPS-induced nitric oxide (NO) and prostaglandin E2 production in a dose-dependent manner. Moreover, HHMP treatment considerably suppressed LPS-induced expression of inducible nitric oxide synthase and cyclooxygenase-2. We also demonstrated the mechanisms of HHMP inhibition of inflammatory responses in LPS-stimulated RAW 264.7 cells via Western blot analysis and immunofluorescence staining. Furthermore, HHMP significantly inhibited NO production in LPS-stimulated zebrafish larvae. Consequently, we established that HHMP significantly inhibited the LPS-induced activation of NF-κB and MAPK and the nuclear translocation of p65 in RAW 264.7 cells. Taken together, our findings demonstrate the effect of HHMP on LPS-induced inflammatory responses in vitro and in vivo, suggesting its potential to be used as a natural anti-inflammatory agent.

Houttuynia cordata Thunb. (HC), Glycyrrhiza uralensis Fischer (GU), Forsythia suspense (Thunb.) Vahl (FS), and Lonicera japonica Thunb. (LJ) are Chinese herbs known to possess anti-inflammatory properties. The effects of aqueous extracts of these herbs on the production of the pro-inflammatory mediators, nitric oxide (NO) and tumor necrosis factor-alpha (TNF-α) were examined in an activated macrophage-like cell line, RAW 264.7 cells. Aqueous extracts from FS at 0.0625–2.0 mg/ml inhibited in vitro production of NO and secretion of TNF-α in a dose-dependent manner. FS at 1.0–2.0 mg/ml and 0.125–2.0 mg/ml significantly inhibited NO production and TNF-α, respectively. An extract of LJ demonstrated potent inhibition of both NO production and TNF-α secretion in a dose-dependent manner. An aqueous extract from HC inhibited NO production in a dose-dependent manner, but minimally (approximately 30%) inhibited TNF-α secretion at 0.0625 and 0.125 mg/ml. In contrast, an aqueous extract of GU had a minimal effect on both the production of NO and the secretion of TNF-α. Viability of cells at all concentrations studied was unaffected as determined by MTT cytotoxicity assay and trypan blue dye exclusion. These results suggest that aqueous extracts from FS, LJ and HC have anti-inflammatory actions as measured by inhibition of NO production and/or TNF-α secretion.

Abstract Objective In this study, we evaluated the anti-inflammatory effect of Shiranuhi flower in RAW 264.7 cells. Methods The effects of the extracts and solvent fractions on cell viability and LPS-induced inflammatory responses were investigated in RAW 264.7 cells. Results The results showed that the ethyl acetate fraction (HEF) significantly decreased NO production in RAW 264.7 cells; however, cell viability was not affected. In addition, ELISA assay revealed that HEF significantly inhibited the productions of PGE2, TNF-α, and IL-6. As well, using Western blot analysis, it was observed that HEF significantly reduced the expression levels of iNOS and COX-2 in a dose dependent manner. Furthermore, we detected a reduced phosphorylation of mitogen-activated protein kinases such as p38, JNK, and ERK1/2. This indicates that HEF regulates LPS-induced inflammatory responses, at least in part, via suppressing the MAPK signaling pathway. Correlation analysis also showed that anti-inflammatory activities were highly correlated to antioxidant activities in this study. Characterization of the Shiranuhi flowers for flavonoid contents using HPLC showed varied quantity of narirutin and hesperidin. Conclusion Overall, the results demonstrate that HEF may be a potential anti-inflammatory agent. In addition, our findings contribute to understanding the molecular mechanism underlying the anti-inflammatory effect of Shiranuhi flower.

The extract of Angelicae Dahuricae Radix has traditionally been used as an anti-noceptive remedy in China. In this study, the methanol extract of Angelicae Dahuricae Radix (MEAD) was evaluated to determine if it has anti-noceptive and anti-inflammatory action. The anti-nociceptive activities of MEAD were evaluated by determining the writhing response and sleeping time, as well as by a formalin test. In addition, the anti-inflammatory activities of MEAD were evaluated by a vascular permeability test as well as by measuring the carrageenan-induced paw edema and conducting a myeloperoxidase (MPO) assay. MEAD (600 and 1200 mg/kg) exhibited anti-inflammatory effects on acetic acid-induced vascular permeability, carrageenan-induced paw edema, and MPO activity. Moreover, the results of the formalin test, the acetic acid-induced writhing response and the pentobarbital-induced sleeping time indicated that MEAD had anti-nociceptive effects that occurred in a concentration-dependent manner. To determine the mechanism by which MEAD exerted its effects on the expression of inducible nitric oxide synthase (iNOS) and the production of nitric oxide (NO) by treated murine macrophage RAW 264.7 cells was evaluated. Similar to the in vivo activities, both the iNOS expression and NO production were significantly suppressed by MEAD in a dose-dependent manner. Furthermore, MEAD inhibited the activating phosphorylation of ERK1/2. These results provide a scientific basis that explains the mechanism by which Angelicae Dahuricae Radix relieves inflammatory pain.

In this study, we evaluated the anti-inflammatory effects of moringa (Moringa oleifera Lam.), a natural biologically active substance, by determining its inhibitory effects on pro-inflammatory mediators in lipopolysaccharide (LPS)-stimulated macrophage RAW264.7 cells. Extracts from different parts of moringa (root, leaf, and fruit) reduced LPS-induced nitric oxide (NO) release in a dose-dependent manner. The moringa fruit extract most effectively inhibited LPS-induced NO production and levels of inducible nitric oxide synthase (iNOS). The moringa fruit extract also was shown to suppress the production of inflammatory cytokines including IL-1β, TNF-α, and IL-6. Furthermore, moringa fruit extract inhibited the cytoplasmic degradation of I κ B -α and the nuclear translocation of p65 proteins, resulting in lower levels of NF -κ B transactivation. Collectively, the results of this study demonstrate that moringa fruit extract reduces the levels of pro-inflammatory mediators including NO , IL-1β, TNF-α, and IL-6 via the inhibition of NF -κ B activation in RAW264.7 cells. These findings reveal, in part, the molecular basis underlying the anti-inflammatory properties of moringa fruit extract.
