Abstract
The spice turmeric, which has the Latin name Curcuma longa (C. longa), has various physiological effects. This study evaluated the effects of a hot water mixture with supercritical carbon dioxide C. longa extracts, CLE, and the potential active components of C. longa, turmeronols A and B and bisacurone on inflammation and glucose metabolism. First, we investigated the effect of CLE and the potential active components of C. longa on lipopolysaccharide-induced inflammation in RAW264.7 macrophages. We found a significant decrease in the production of interleukin (IL)-1β, IL-6, tumor necrosis factor (TNF)-α, and nitric oxide with CLE, turmeronol A, and bisacurone, Significant inhibition of each of these substances was also observed, except for TNF-α with turmeronol B. The second part of our work was a 12-week randomized, double-blind, placebo-controlled study in healthy but borderline adults aged 40 to 69 years with overweight and normal/prediabetes glycemia. We compared blood inflammatory and glycometabolic markers in the CLE (n = 55) and placebo groups (n = 55). We found significantly lower serum high-sensitivity C-reactive protein and hemoglobin A1c levels in the CLE group. This group also showed significant improvements in postprandial hyperglycemia and insulin sensitivity indices. Our findings indicate that CLE may reduce low-grade inflammation and thus improve insulin sensitivity and postprandial hyperglycemia.

Turmeronols (A and B) from Curcuma longa have anti-inflammatory effects in lipopolysaccharide-stimulated BV-2 microglial cells by reducing NF-κB signaling. BIOSCIENCE OF MICROBIOTA, FOOD AND HEALTH 2023; 42:172-179.

Abstract
Turmeronols (A and B), bisabolane-type sesquiterpenoids found in turmeric, reduce inflammation outside the brain in animals; however, their effects on neuroinflammation, a common pathology of various neurodegenerative diseases, are not understood. Inflammatory mediators produced by microglial cells play a key role in neuroinflammation, so this study evaluated the anti-inflammatory effects of turmeronols in BV-2 microglial cells stimulated with lipopolysaccharide (LPS). Pretreatment with turmeronol A or B significantly inhibited LPS-induced nitric oxide (NO) production; mRNA expression of inducible NO synthase; production of interleukin (IL)-1β, IL-6, and tumor necrosis factor α and upregulation of their mRNA expression; phosphorylation of nuclear factor-κB (NF-κB) p65 proteins and inhibitor of NF-κB kinase (IKK); and nuclear translocation of NF-κB. These results suggest that these turmeronols may prevent the production of inflammatory mediators by inhibiting the IKK/NF-κB signaling pathway in activated microglial cells and can potentially treat neuroinflammation associated with microglial activation.

Abstract
This study aimed to elucidate the mechanism of action of Runyan Mixture in treating pharyngitis using a network pharmacological approach. The active components of the Runyan Mixture were obtained from the traditional chinese medicine systems pharmacology database and evaluated using Lipinski's rules. The SwissTargetPrediction database was used to predict the action targets of the Runyan Mixture, and a protein-protein interaction network was constructed using the STRING database. Moreover, the anti-inflammatory effect of Runyan Mixture was validated in vitro using the lipopolysaccharide induced inflammation in macrophages. The Runyan Mixture was the liquid preparation from 8 traditional Chinese medicine. A total of 89 types of active components, 53 core targets, and 98 signaling pathways (P < .001) were identified for the Runyan Mixture. The main action targets were EGFR, MAPK1, AKT1, PIK3CA, NFKB1, SRC, TNF, MAPK8, MET, and PTGS2. Among the identified signaling pathways, 20 were associated with microbial infection and 24 were related to the immune-inflammatory response. Experimental results in vitro showed that Runyan Mixture could significantly inhibit the expression of interleukin-1, interleukin-6, and tumor necrosis factor-α (P < .05) in macrophages by lipopolysaccharide stimulation. Based on the results of the protein-protein interaction network analysis and the anti-inflammatory effect in vitro, the efficiency of the Runyan Mixture in pharyngitis treatment could be attributed to the inhibition of the inflammatory response.

Don Extract via Blockage of the NF-κB/JNK Signaling Pathways in LPS-Activated Microglial Cells. PLANTS (BASEL, SWITZERLAND) 2022; 11:3095. [PMID: 36432823 PMCID: PMC9693526 DOI: 10.3390/plants11223095] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Revised: 11/11/2022] [Accepted: 11/11/2022] [Indexed: 06/16/2023]
Abstract
Symplocos sumuntia Buch.-Ham. ex D. Don (S. sumuntia) is a traditional medicinal herb used in Asia to treat various pathologies, including cough, stomachache, tonsillitis, hypertension, and hyperlipidemia. Although the anti-inflammatory activity of S. sumuntia has been reported, little is known about its anti-inflammatory activity and molecular mechanisms in microglial cells. Therefore, we investigated the inhibitory effects of S. sumuntia methanol extract (SSME) on the inflammatory responses in lipopolysaccharide (LPS)-treated BV2 cells. The SSME significantly inhibited the LPS-stimulated inducible nitric oxide synthase and cyclooxygenase-2 expression, as well as the production of nitric oxide (NO), a proinflammatory mediator. The production of proinflammatory cytokines, including interleukin (IL)-6, tumor necrosis factor-α, and IL-1β, was suppressed by the SSME in the LPS-induced BV2 cells. The mechanism underlying the anti-inflammatory effects of SSME involves the suppression of the LPS-stimulated phosphorylation of mitogen-activated protein kinases (MAPKs) such as JNK. Moreover, we showed that the LPS-stimulated nuclear translocation of the nuclear factor-κB (NF-κB)/p65 protein, followed by IκB degradation, was decreased by the SSME treatment. Collectively, these results showed that the SSME induced anti-inflammatory effects via the suppression of the MAPK signaling pathways, accompanied by changes in the NF-κB translocation into the nucleus. Therefore, SSME may be employed as a potential therapeutic candidate for various inflammatory diseases.

RECENT ADVANCES IN INFLAMMATION & ALLERGY DRUG DISCOVERY 2022; 15:RAIAD-EPUB-120287. [PMID: 35043776 DOI: 10.2174/2772270816666220119122259] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/02/2021] [Revised: 11/09/2021] [Accepted: 12/17/2021] [Indexed: 06/14/2023]
Abstract
BACKGROUND Inflammation is the response to the reaction of any type of bodily injury by elevating cellular metabolism and releasing soluble mediators. It is also a contributing factor of pain. Predimenol, which has previously been known as DLBS1442, is a bioactive extract from Phaleria macrocarpa (Scheff.) Boerl (Thymelaceae). It can be an alternative treatment for pain relief, especially for long-term use. OBJECTIVE The objective of this study is to evaluate the anti-inflammatory activities of predimenol through the evaluation of several parameters involved in the inflammatory pathway. METHODS Cyclooxygenase 2 (COX-2), inducible nitric oxide synthase (iNOS), tumor necrosis factor- (TNF-), interleukin-1β (IL-1β), interleukin-2 (IL-2), interleukin-6 (IL-6), and nuclear factor B (NF-B) were observed after 24 h exposure of predimenol (0-180 µg/mL) to lipopolysaccharides (LPS)-activated RAW 264.7 cell. The inflammatory markers were measured using nitric oxide (NO) assay and enzyme-linked immunosorbent assay (ELISA) for COX-2 inhibitor assay. The gene expressions of TNF-α, IL-1β, IL-2 and IL-6 were quantified using the polymerase chain reaction (PCR) method. Western blotting was applied to detect phosphorylated IB kinase (IKK) protein to confirm the activation of NF-κB. RESULTS Our study showed a similar mechanism with most non-steroidal anti-inflammatory drugs (NSAIDs). Predimenol consistently downregulated the expression of iNOS and inhibited COX-2 activity. Moreover, predimenol significantly inhibited the LPS-induced production of NO, TNF-α, IL-1β, IL-2 and IL-6. Down-regulation of these markers was suggested due to the reduction of NF-κB transcription level and activation by predimenol. CONCLUSION Predimenol exhibits anti-inflammatory activities through NF-kB inactivation-mediated COX-2 suppression, which may suggest that predimenol is a potential analgesic and anti-inflammatory agent.

Abstract
The normal inflammatory reaction protects the body from harmful external factors, whereas abnormal chronic inflammation can cause various diseases, including cancer. The purpose of the present study was to investigate the anti‑inflammatory activity of a mixture of Chrysanthemum zawadskii, peppermint and Glycyrrhiza glabra (CPG) by analyzing the expression levels of inflammatory mediators, cytokines and transcription factors in lipopolysaccharide (LPS)‑stimulated Raw264.7 cells. A nitric oxide assay, ELISA, western blotting and immunofluorescence staining were performed to investigate the anti‑inflammatory activity of the CPG mixture. Pretreatment of Raw264.7 cells with CPG inhibited the increase of inflammatory mediators (inducible nitric oxide synthase, cyclooxygenase‑2 and IFN‑β) induced by LPS. Additionally, it inhibited the production of pro‑inflammatory cytokines (TNF‑α, IL‑6 and IL‑1β). CPG suppressed LPS‑induced phosphorylation of STAT1, AKT, Iκb and NF‑κB. Furthermore, CPG inhibited the translocation of NF‑κB into the nucleus. In summary, CPG could inhibit LPS‑induced inflammation, which occurs primarily through the AKT/Iκb/NF‑κB signaling pathway in RAW264.7 cells.

Abstract
AIM To test the effectiveness of marketed polyherbal formulations on lipopolysaccharide induced inflammatory conditions in macrophages. BACKGROUND Usage of herbal compounds among patients suffered by arthritis and cancer is increasing every year. Many anti-inflammatory herbal products available in the market should be screened thoroughly for their possible mechanism of action. OBJECTIVE Joint Pain Spl (JPS) is a polyherbal dietary food supplement composed of 13 herbal plants and Rumalaya Forte (RF) is a polyherbal formulation comprising of 6 herbal plants were tested for its cytotoxicity, as well as antioxidant and anti-inflammatory activity in LPS treated IC-21 peritoneal macrophages. METHODS Commercially available JPS and RF powder was used to prepare the extract. The aqueous and methanol extracts were quantified for the presence of phenolic and flavonoid compound and confirmed with HPLC. In vitro DPPH free scavenging activity was performed. Cytotoxicity was tested by MTT assay. Anti-inflammatory activity was tested using lipopolysaccharide stimulated IC-21 peritoneal macrophage cells. RESULTS The phytochemical screening showed the presence of phenolic and flavonoid compounds in JPS and RF. The aqueous and methanol extracts of JPS and RF possesses significant DPPH free radical scavenging activity. MTT assay revealed that 90.64% (aqueous extract) and 92.21% (methanol extract) of exposed macrophages are viable even after 24h exposure of maximal tested concentrations of herbal formulations. Pre-treatment of JPS and RF on LPS induced IC-21 macrophages showed an reduction in nitric oxide production (maximal 79.95%) and high level of superoxide anion scavenging activity (maximal 82.5%) over control. CONCLUSION The two tested poly herbal formulations such as JPS and RF possesses anti-inflammatory activity by modulating free radical generation in IC-21 macrophages. Thus the presence of the phenolic and flavonoid compounds may contribute to the antioxidant activity.

Abstract
Psoriasis is a chronic inflammatory skin disorder in humans, and the inflammatory reaction plays an important role in development and onset of psoriasis. 4'-O-β-D-glucosyl-5-O-methylvisamminol (4GMV) is one of the major active chromones isolated from Saposhnikoviae divaricata (Turcz.) Schischk, which has been reported to exhibit excellent anti-inflammatory activities. However, the possible therapeutic effect on psoriasis and underlying mechanism has not been reported. Thus, the aim of this study was to investigate the protective effect of 4GMV on the imiquimod (IMQ)-induced psoriasis-like lesions in BALB/c mice and the anti-inflammatory effect on the lipopolysaccharide (LPS)-induced inflammation in RAW264.7 macrophages. The results demonstrated that 4GMV decreased IMQ-induced keratinocyte proliferation and inflammatory cell infiltration. Moreover, 4GMV treatment significantly inhibited the production of NO, PEG 2, and cytokines such as interleukin (IL)-1β, IL-6, interferon (IFN)-γ, and IL-22 in LPS-stimulated RAW264.7 macrophages. 4GMV also suppressed the LPS-upregulated protein expressions of iNOS and COX-2 in a dose-dependent manner. Furthermore, qRT-PCR analysis showed that 4GMV down-regulated the mRNA level of IL-1β and IL-6 expression. Further studies by western blot indicated that 4GMV inhibited the activation of upstream mediator NF-κB by suppressing the expression of TLR4 and the phosphorylation of IκBα and p65. The phosphorylation of JNK, p38, and ERK were also markedly reversed by 4GMV in LPS-treated RAW264.7 macrophages. Taken together, these results demonstrated that 4GMV showed a protective effect in IMQ-induced psoriasis-like mice and inhibited inflammation through the NF-κB and MAPK signaling pathways, indicating that 4GMV might be a potential therapeutic drug for psoriasis.

Molecules 2020; 25:molecules25061336. [PMID: 32183436 PMCID: PMC7144571 DOI: 10.3390/molecules25061336] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/22/2020] [Revised: 03/13/2020] [Accepted: 03/13/2020] [Indexed: 01/03/2023] Open
Abstract
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.

Chemical composition of tetraploid Gynostemma pentaphyllum gypenosides and their suppression on inflammatory response by NF-κB/MAPKs/AP-1 signaling pathways. Food Sci Nutr 2020; 8:1197-1207.

Abstract
The chemical composition and anti-inflammatory activity of gypenosides isolated from tetraploid Gynostemma pentaphyllum (GP) leaves were investigated. The gypenosides accounted for 7.43 mg/g of the tested GP sample, which were composed of four major saponins including isomers of gypenoside 1 and 2 (C47H76O18), 3 (C47H76O17), and 4 (C46H74O17). Pretreatment of gypenosides reduced mRNA expressions of the proinflammatory mediators in LPS-stimulated RAW264.7 macrophage cells, such as IL-6, IL-1β, COX-2, and TNF-α in a dose-dependent manner. The secreted protein levels of IL-6 and TNF-α, and NO production were also decreased by gypenosides within the concentration range of 50-200 μg/ml. Moreover, the mechanism studies demonstrated that gypenosides (200 μg/ml) treatment significantly inhibited the nuclear translocation of nuclear factor-κB and activator protein 1 (c-Fos and c-Jun) through down-regulating the phosphorylation of their upstream IκB kinase and mitogen-activated protein kinases (MAPKs), especially that of c-Jun N-terminal kinase and extracellular regulated protein kinase(JNK and ERK), but not that of the p38 MAPK. These results suggested that the gypenosides might have potential anti-inflammatory effect and use for improving human health.

Abstract
Chronic inflammation depends on inflammatory mediators produced by activated macrophages and is the common pathological basis for various diseases. Turmeronol is a sesquiterpenoid found in the spice turmeric (Curcuma longa), which is known to have anti-inflammatory activity. To elucidate the anti-inflammatory mechanism of turmeronol, we investigated the influence of turmeronol A and turmeronol B in mouse macrophages (RAW264.7 cells) stimulated with lipopolysaccharide (LPS). Pretreatment of RAW264.7 cells with either turmeronol A or B significantly inhibited LPS-induced production of prostaglandin E2 and nitric oxide, as well as expression of mRNAs for the corresponding synthetic enzymes. In addition, the turmeronols significantly inhibited LPS-induced upregulation of interleukin-1β, interleukin-6, and tumor necrosis factor-α at the mRNA and protein levels. Both turmeronols also inhibited nuclear translocation of nuclear factor κB (NF-κB), with a similar time course to the NF-κB inhibitor pyrrolidine dithiocarbamate, but not curcumin (another NF-κB inhibitor). Thus, both turmeronols prevented activation of macrophages and inflammatory mediator production, possibly by suppressing activation of NF-κB, and therefore have potential for use in preventing chronic inflammatory diseases.

The protective effects of PCPA against monocrotaline-induced pulmonary arterial hypertension are mediated through the downregulation of NFAT-1 and NF-κB. Int J Mol Med 2017; 40:155-163. [PMID: 28560440 PMCID: PMC5466386 DOI: 10.3892/ijmm.2017.3001] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2016] [Accepted: 05/17/2017] [Indexed: 12/31/2022] Open
Abstract
Inflammation and remodeling play a role in the pathogenesis of pulmonary arterial hypertension (PAH). Nuclear factor-κB (NF-κB) and nuclear factor of activated T cells-1 (NFAT-1) participate in inflammation and remodeling in a number of diseases. As a tryptophan hydroxylase inhibitor, 4-chloro-DL-phenylalanine (PCPA) had been reported to exert anti-inflammatory and remodeling effects. Therefore, we hypothesized that PCPA may attenuate monocrotaline (MCT)-induced PAH through the NFAT-1 and NF-κB signaling pathways. In order to confirm our hypothesis, we divided 68 Sprague-Dawley male rats into 4 groups as follows: the control, MCT, MCT + P1 and MCT + P2 groups. MCT was administered at a dose of 60 mg/kg once via intraperitoneal injection. PCPA was administered via intraperitoneal injection at a dose of 50 or 100 mg/kg once daily for 21 consecutive days. We then measured the hemodynamic index and morphological analysis was carried out on the lung tissues. Western blot analysis and immunohistochemistry were used to examine the levels of NFAT-1 and NF-κB p-65. The expression levels of phosphorylated inhibitor of NF-κB kinase (p-IKK), IKK, phosphorylated extracellular signal-regulated kinase (p-ERK), ERK, intercellular adhesion molecule-1 (ICAM-1) and interleukin-6 (IL-6) were examined by western blot analysis. MCT was found to significantly induce PAH, with inflammation and remodeling of the lung tissues. This was associatd with an increased expression of NFAT-1, p-IKK, p-ERK and nuclear p65. PCPA significantly attenuated MCT-induced inflammation and arterial remodeling, and decreased the expression of NFAT-1, as well as that of relevant proteins of the NF-κB signaling pathway. The above-mentioned findings suggest that the inhibitory effects of PCPA on MCT-induced inflammation and arterial remodeling are related to the downregulation of the NFAT-1 and NF-κB signaling pathways in rats with PAH.

Abstract
Objective: Breast cancer is a heterogeneous disease and very common malignancy in women worldwide. The efficacy
of chemotherapy as an important part of breast cancer treatment is limited due to its side effects. While pharmaceutical
companies are looking for better chemicals, research on traditional medicines that generally have fewer side effects is
quite interesting. In this study, apoptosis and necrosis effect of Arctium lappa and doxorubicin was compared in MCF7,
and MDA-MB-231 cell lines. Materials and Methods: MCF7 and MDA-MB-231 cells were cultured in RPMI 1640
containing 10% FBS and 100 U/ml penicillin/streptomycin. MTT assay and an annexin V/propidium iodide (AV/PI) kit
were used respectively to compare the survival rate and apoptotic effects of different concentrations of doxorubicin and
Arctium lappa root extract on MDA-MB-231 and MCF7 cells. Results: Arctium lappa root extract was able to reduce
cell viability of the two cell lines in a dose and time dependent manner similar to doxorubicin. Flow cytometry results
showed that similar to doxorubicin, Arctium Lappa root extract had a dose and time dependent apoptosis effect on
both cell lines. 10μg/mL of Arctium lappa root extract and 5 μM of doxorubicin showed the highest anti-proliferative
and apoptosis effect in MCF7 and MDA231 cells. Conclusion: The MCF7 (ER/PR-) and MDA-MB-231 (ER/PR+)
cell lines represent two major breast cancer subtypes. The similar anti-proliferative and apoptotic effects of Arctium
lappa root extract and doxorubicin (which is a conventional chemotherapy drug) on two different breast cancer cell
lines strongly suggests its anticancer effects and further studies.

Abstract
BACKGROUND Activation of macrophage is involved in many inflammation diseases. Lipopolysaccharide (LPS) is a powerful inflammatory signal contributing to monocytes/macrophages activation associated with increased proinflammatory cytokines expressions. We recently identified that vaccarin was expected to protect endothelial cells from injury. Hypaphorine was abundantly found in vaccaria semen. However, the potential roles and underlying mechanisms of vaccaria hypaphorine on macrophage inflammation have been poorly defined. METHODS This study was designed to determine the effects of vaccaria hypaphorine on LPS-mediated inflammation in RAW 264.7 cells. RESULTS In this study, we demonstrated that vaccaria hypaphorine dramatically ameliorated LPS-induced nitric oxide (NO) release and productions of proinflammatory cytokines including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), IL-6, IL-10, monocyte chemoattractant protein 1 (MCP-1) and prostaglandin E2 (PGE2) in RAW 264.7 cells. LPS-stimulated expressions of cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) were down-regulated by vaccaria hypaphorine. Furthermore, vaccaria hypaphorine retarded LPS-induced phosphorylation of ERK, nuclear factor kappa beta (NFκB), NFκB inhibitor IκBα, and IKKβ. Immunofluorescence staining revealed that vaccaria hypaphorine eliminated the nuclear translocation of NFκB in LPS-treated RAW 264.7 cells. CONCLUSION It was seen that vaccaria hypaphorine counteracted inflammation via inhibition of ERK or/and NFκB signaling pathways. Collectively, we concluded that vaccaria hypaphorine can be served as an anti-inflammatory candidate.

Abstract
BACKGROUND/OBJECTIVES Although the antioxidative effects of lycopene are generally known, the molecular mechanisms underlying the anti-inflammatory properties of lycopene are not fully elucidated. This study aimed to examine the role and mechanism of lycopene as an inhibitor of inflammation. METHODS/MATERIALS Lipopolysaccharide (LPS)-stimulated SW 480 human colorectal cancer cells were treated with 0, 10, 20, and 30 µM lycopene. The MTT assay was performed to determine the effects of lycopene on cell proliferation. Western blotting was performed to observe the expression of inflammation-related proteins, including nuclear factor-kappa B (NF-κB), inhibitor kappa B (IκB), mitogen-activated protein kinase (MAPK), extracellular signal-related kinase (ERK), c-jun NH2-terminal kinase (JNK), and p38 (p38 MAP kinase). Real-time polymerase chain reaction was performed to investigate the mRNA expression of tumor necrosis factor α (TNF-α), interleukin-1 beta (IL-1β), interleukin-6 (IL-6), inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2). Concentrations of nitric oxide (NO) and prostaglandin E2 (PGE2) were determined via enzyme-linked immunosorbent assays. RESULTS In cells treated with lycopene and LPS, the mRNA expression of TNF-α, IL-1β, IL-6, iNOS, and COX-2 were decreased significantly in a dose-dependent manner (P < 0.05). The concentrations of PGE2 and NO decreased according to the lycopene concentration (P < 0.05). The protein expressions of NF-κB and JNK were decreased significantly according to lycopene concertation (P < 0.05). CONCLUSIONS Lycopene restrains NF-κB and JNK activation, which causes inflammation, and suppresses the expression of TNF-α, IL-1β, IL-6, COX-2, and iNOS in SW480 human colorectal cancer cells.

Shikimic acid inhibits LPS-induced cellular pro-inflammatory cytokines and attenuates mechanical hyperalgesia in mice. Int Immunopharmacol 2016; 39:97-105.

Abstract
BACKGROUND AND AIMS Shikimic acid (SA) is present in a wide variety of plants and microorganisms used in traditional and folk medicine and also is an essential starting material for the synthesis of the antiviral drug Oseltamivir (Tamiflu®). Some pharmacological actions observed in SA-enriched products include antioxidant and anti-inflammatory activities. Here, we investigated the anti-inflammatory and antinociceptive actions of isolated SA. METHODS RAW 264.7 macrophage cells were treated with bacterial LPS (1μg/mL) and the effect of SA on the modulation of cell viability, nitric oxide (NO) production, TNF-α, and IL-1β content and MAPK (ERK1/2 and p38) activation was evaluated. Besides, the anti-hyperalgesic actions of SA on in vivo model of mechanical hyperalgesia induced by carrageenan (CG), dopamine (DA), TNF-α and prostaglandin (PGE2) were assessed. RESULTS In RAW 264.7 cells, SA suppressed LPS-induced decrease in cell viability and nitrite accumulation to control values and inhibited up-regulation of TNF-α (65%) and IL-1β (39%). These effects may be mediated at least in part by inhibition of LPS-induced ERK 1/2 (22%) and p38 (17%) phosphorylation. In mice, SA at 50, 100, and 200mg/kg decreased formalin-induced nociceptive behavior (around 50%) and inhibited the inflammatory nociception induced by TNF-α and PGE2 (50 to 75% each). Moreover, SA (100 and 200mg/kg) significantly attenuated the mechanical hyperalgesia induced by CG and DA (25 to 40% each). CONCLUSIONS These results indicate that SA presents anti-inflammatory actions with potential for development of drugs to treat pro-inflammatory and painful conditions.

Abstract
Fucofuroeckol-A (FF) isolated from an edible perennial brown seaweedEisenia bicycliswas shown to be potent anti-inflammatory agents. FF suppressed the production of nitric oxide (NO) and prostaglandin E2(PGE2) and the expression of inducible nitric oxide synthase and cyclooxygenase-2 dose dependently in lipopolysaccharide- (LPS-) induced RAW 264.7 mouse macrophages. An enzyme-linked immunosorbent assay and cytometric bead array assay demonstrated that FF significantly reduced the production of proinflammatory cytokines, such as interleukin-6 and tumor necrosis factor-α, and that of the monocyte chemoattractant protein-1. Moreover, FF reduced the activation of nuclear factorκB (NF-κB) and mitogen-activated protein kinases (MAPKs). These results strongly suggest that the inhibitory effects of fucofuroeckol-A fromE. bicyclison LPS-induced NO and PGE2production might be due to the suppression of the NF-κB and MAPK signaling pathway.
