Chuju, the flower of <em>Chrysanthemum morifolim</em> cv. Chuju, is a traditional medicine-food material used in China. Bioassay-guided chemical investigation on Chuju led the isolation of 16 flavonoids (<strong>1-16</strong>) characterized as quercetin (<strong>1</strong>), isorhamnetin 3-<em>O</em>-β-D-glucoside (<strong>2</strong>), eriodictyol (<strong>3</strong>), pyracanthoside (<strong>4</strong>), apigenin (<strong>5</strong>), apigetrin (<strong>6</strong>), acacetin (<strong>7</strong>), acacipetalin (<strong>8</strong>), luteolin (<strong>9</strong>), diosmetin (<strong>10</strong>), spinacetin (<strong>11</strong>), axillarin (<strong>12</strong>), bonanzin (<strong>13</strong>), cirsiliol (<strong>14</strong>), chrysosplenol D (<strong>15</strong>) and artemetin (<strong>16</strong>). Among them, compounds (11-16) were first reported from the <em>Chrysanthemum</em> species. Chuju flavonoids displayed strong antioxidant in DPPH (1, 1-diphenyl-2- picrylhydrazyl) radical scavenging assay, and high anti-inflammatory activity by inhibiting NO production in LPS-induced RAW 264.7 cells. These findings suggests that Chuju is an ideal source of natural flavonoids with significant antioxidant and anti-inflammatory effects, and is worthy of further development as health-promoting food or supplement.

Background: The purpose of this study was to investigate whether Sibseonsan (SSS) is an effective anti-inflammatory, anti-wrinkling, and whitening agent.Methods: To determine whether SSS had an anti-inflammatory effect, a murine macrophage cell line was used (RAW 264.7) and production of DPPH, NO, TNF-α, and PGE2 were measured. To ascertain potential anti-wrinkle effects of SSS in these cells, collagenase and elastase production were measured. To verify whether SSS had a whitening effect, tyrosinase activity and DOPA staining were performed using a melanoma cell line (B16/F10).Results: There was no significant reduction in survival of SSS-treated RAW 264.7 cells, up to 400 μg/mL. Free radical scavenging (23.96 ± 1.85%) was observed in RAW 264.7 cells treated with SSS at a concentration of 400 μg/mL. The SSS treatment group (400 μg/mL) significantly inhibited NO production compared with the LPS stimulated treatment group. The SSS treatment of macrophage cells appeared to reduce production of TNF-α in a concentration dependent manner. There was a significant reduction in the concentration of PGE<sub>2</sub> by about 25% in the SSS treatment (400 μg/mL) group (<i>p</i> = 0.05). Compared with the control, the production of collagenase and elastase in B16/F10 cells treated with SSS (400 μg/mL) was greater by 26.37% and 45.71%, respectively. The SSS treatment (400 μg/mL) group showed a significant reduction by about 17% in tyrosinase production in B16/F10 cells. The SSS treatment group showed little change in DOPA staining.<br>Conclusion: SSS extract may be useful for the treatment and prevention of inflammatory diseases and may have anti-wrinkle and whitening effects. These results may support the use of SSS in clinical practice.

Aucklandia lappa Decne., known as “Mok-hyang” in Korea, has been used for the alleviation of abdominal pain, vomiting, diarrhea, and stress gastric ulcers in traditional oriental medicine. We investigated the anti-inflammatory and antioxidative effects of the ethanol extract of Aucklandia lappa Decne. (ALDE) in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. ALDE significantly inhibited the LPS-induced nitric oxide (NO) production and reduced inducible nitric oxide synthase (iNOS) expression in RAW 264.7 cells. The production of other proinflammatory mediators, including COX-2, interleukin (IL)-6, IL-1β, and tumor necrosis factor (TNF)-α, was reduced by ALDE in LPS-stimulated RAW 264.7 cells. The mechanism underlying the anti-inflammatory effects of ALDE was elucidated to be the suppression of LPS-induced nuclear translocation of p65, followed by the degradation of IκB and the inhibition of the phosphorylation of mitogen-activated protein kinases (MAPK). In addition, ALDE showed enhanced radical scavenging activity. The antioxidant effect of ALDE was caused by the enhanced expression of heme oxygenase (HO-1) via stabilization of the expression of the nuclear transcription factor E2-related factor 2 (Nrf2) pathway. Collectively, these results indicated that ALDE not only exerts anti-inflammatory effects via the suppression of the NF-κB and MAPK pathways but also has an antioxidative effect through the activation of the Nrf2/HO-1 pathway.

Astragalus membranaceus (AM) has been used for anti-oxidative, anti-inflammatory, anti-cancer, and immunomodulatory activities. In this study, we confirmed that the anti-oxidative and anti-inflammatory effects of AM were enhanced after it was fermented by Lactiplantibacillus plantarum. The anti-oxidative effect was measured by 2,2-Diphenyl-1-picrylhydrazyl (DPPH) radical levels, total phenolic contents (TPC), reducing power, and H2O2 levels. AM-LP MG5145 and MG5276 showed higher free radical scavenging activity than AM-NF (51.22%). In addition, AM-LP MG5145 and MG5276 showed higher TPC (49.11 mg GAE/mL), reducing power (OD700 = 0.37), and H2O2 (1.71 µM) than AM-NF. The calycosin contents determined to AM-NF (17.24 ng/mL), AM-LP MG5145 (139.94 ng/mL), and MG5276 (351.01 ng/mL) using UPLC-ESI-MS/MS. Anti-inflammatory effects were analyzed by investigating the inhibitory effects of fermented AM on cytotoxicity, NO production, and mRNA expression of COX-2, iNOS, NF-κB, and TNF-α in LPS-induced RAW 264.7 cells. AM-LP MG5145 and MG5276 showed no cytotoxicity. AM-LP MG5145 (50.86%) and MG5276 (51.66%) inhibited NO production in LPS-induced RAW 264.7 cells. Moreover, AM-LP MG5145 and MG5276 downregulated macrophage iNOS, COX2, TNF-ɑ, and NF-κB expression. In conclusion, A. membranaceus fermented by L. plantarum MG5145 and MG5276 can be used in cosmetics and health foods as natural antioxidant compounds.

Reduced Toxicity

Biorenovation is a microbial enzyme-catalyzed structural modification of organic compounds with the potential benefits of reduced toxicity and improved biological properties relative to their precursor compounds. In this study, we synthesized a novel compound verified as formononetin 7-O-phosphate (FMP) from formononetin (FM) using microbial biotransformation. We further compared the anti-inflammatory properties of FMP to FM in lipopolysaccharide (LPS)-treated RAW264.7 macrophage cells. We observed that cell viabilities and inhibitory effects on LPS-induced nitric oxide (NO) production were greater in FMP-treated RAW 264.7 cells than in their FM-treated counterparts. In addition, FMP treatment suppressed the production of proinflammatory cytokines such as prostaglandin-E2 (PGE2), interleukin-6 (IL-6), and interleukin-1β (IL-1β) in a dose-dependent manner and concomitantly decreased the mRNA expression of inducible NO synthase (iNOS) and cyclooxygenase-2 (COX-2). We also found that FMP exerted its anti-inflammatory effects through the downregulation of the extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK), and nuclear factor kappa B (NF-κB) signaling pathways. In conclusion, we generated a novel anti-inflammatory compound using biorenovation and demonstrated its efficacy in cell-based in vitro assays.

This study aimed to produce and optimize a Cordyceps militaris-based oil-in-water (O/W) nanoemulsion (NE) encapsulated in sea buckthorn oil (SBT) using an ultrasonication process. Herein, a nonionic surfactant (Tween 80) and chitosan cosurfactant were used as emulsifying agents. The Cordyceps nanoemulsion (COR-NE) was characterized using Fourier-transform infrared spectroscopy (FT-IR), dynamic light scattering (DLS), and field-emission transmission electron microscope (FE-TEM). The DLS analyses revealed that the NE droplets were 87.0 ± 2.1 nm in diameter, with a PDI value of 0.089 ± 0.023, and zeta potential of −26.20 ± 2. The small size, low PDI, and stable zeta potential highlighted the excellent stability of the NE. The NE was tested for stability under different temperature (4 °C, 25 °C, and 60 °C) and storage conditions for 3 months where 4 °C did not affect the stability. Finally, in vitro cytotoxicity and anti-inflammatory activity were assessed. The results suggested that the NE was not toxic to RAW 264.7 or HaCaT (human keratinocyte) cell lines at up to 100 µL/mL. Anti-inflammatory activity in liposaccharides (LPS)-induced RAW 264.7 cells was evident at 50 µg/mL and showed inhibition of NO production and downregulation of pro-inflammatory gene expression. Further, the NE exhibited good antioxidant (2.96 ± 0.10 mg/mL) activity and inhibited E. coli and S. aureus bacterial growth. Overall, the COR-NE had greater efficacy than the free extract and added significant value for future biomedical and cosmetics applications.

Abstract Background Inflammation plays a crucial role in the pathogenesis of many diseases such as arthritis and atherosclerosis. In the present study, we evaluated anti-inflammatory activity of sterol-rich fraction prepared from Spirogyra sp., a freshwater green alga, in an effort to find bioactive extracts derived from natural sources. Methods The sterol content of ethanol extract of Spirogyra sp. (SPE) was enriched by fractionation with hexane (SPEH), resulting 6.7 times higher than SPE. Using this fraction, the in vitro and in vivo anti-inflammatory activities were evaluated in lipopolysaccharides (LPS)-stimulated RAW 264.7 cells and zebrafish. Results SPEH effectively and dose-dependently decreased the production of nitric oxide (NO) and prostaglandin E2 (PGE2). SPEH suppressed the production of pro-inflammatory cytokines including interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and IL-1β through downregulating nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression in LPS-stimulated RAW 264.7 cells without cytotoxicity. The in vivo test results indicated that SPEH significantly and dose-dependently reduced reactive oxygen species (ROS) generation, cell death, and NO production in LPS-stimulated zebrafish. Conclusions These results demonstrate that SPEH possesses strong in vitro and in vivo anti-inflammatory activities and has the potential to be used as healthcare or pharmaceutical material for the treatment of inflammatory diseases.

 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.

The beneficial health promoting effects of ginseng from vitalizing the body to enhancing long life have been well explored very rapidly in the past few years. Up till now many ginsenosides have been discovered for their marvelous therapeutic effects. However during past three years, a novel ginseng compound has been discovered, called gintonin, that differs from other ginsenosides on the basis of its signal transduction and chemical nature. Gintonin has been widely studied for its anti-Alzheimer’s disease activities and other neuropathies. However, its anti-inflammatory activity remained unexplored. In our study we have reported for the first time the anti-inflammatory activity of gintonin on RAW 264.7 cells. We found that gintonin potently suppresses the nitric oxide production without any cytotoxicity at given doses and also efficiently suppressed the levels of proinflammatory cytokines. Moreover, it mediaes its signal transduction via MAPK and NF-κB pathways and revives the levels of mir-34a and mir-93. These findings are valuable for the anti-inflammatory effects of this new compound with particular reference to microRNA involvement in the ginseng family.

This study focused on developing Panos nanoemulsion (P-NE) and enhancing the anti-inflammatory efficacy for the treatment of inflammation. The effects of P-NE were evaluated in terms of Nitric oxide (NO production) in Lipopolysaccharide (LPS), induced RAW 264.7 cells, Reactive oxygen species (ROS) generation using Human Keratinocyte cells (HaCaT), and quantitative polymerase chain reaction (qPCR) analysis. Sea buckthorn oil, Tween 80, and span 80 were used and optimize the process. Panos extract (P-Ext) was prepared using the fermentation process. Further high-energy ultra-sonication was used for the preparation of P-NE. The developed nanoemulsion (NE) was characterized using different analytical methods. Field emission transmission electron microscopy (FE-TEM) analyzed the spherical shape and morphology. In addition, stability was analyzed by Dynamic light scattering (DLS) analysis, where particle size was analyzed 83 nm, and Zeta potential −28.20 ± 2 (mV). Furthermore, 90 days of stability was tested using different temperatures conditions where excellent stability was observed. P-NE are non-toxic in (HaCaT), and RAW264.7 cells up to 100 µg/mL further showed effects on ROS and NO production of the cells at 50 µg/mL. The qPCR analysis demonstrated the suppression of pro-inflammatory mediators for (Cox 2, IL-6, IL-1β, and TNF-α, NF-κB, Ikkα, and iNOS) gene expression. The prepared NE exhibited anti-inflammatory effects, demonstrating its potential as a safe and non-toxic nanomedicine.

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.
