Chamaecyparis obtusa Siebold & Zucc. f. formosana Hayata (Cupressaceae) is one of the treasured conifers in Taiwan. In this study, the wood essential oil of the species was extracted and its anti-inflammatory bioactivities analyzed. The composition analysis of the essential oil yielded a total of 57 compounds with α-terpineol (19.4%), τ-muurolol (16.9%), borneol (16%), and α-cadinol (10.9%) predominating. The anti-inflammatory assays of the essential oil suggest that C. obtusa f. formosana wood oil has no cytotoxicity, and was capable of inhibiting the expressions of tumor necrosis factor (TNF-α), IL-6, IL-1, pro IL-1β, NO, iNOS, and NLRP3 in murine macrophage cells. It was unable, however, to inhibit the expression of COX-2. Further investigation of the effect of the essential oil on the cellular signal transduction indicated that it was capable of inhibiting ERK1/2, JNK1/2 and p38; it also showed excellent inhibition against ROS. Thus, the overall results indicated that C. obtusa f. formosana wood oil had very good anti-inflammatory efficacies.

Saponarin{5-hydroxy-2-(4-hydroxyphenyl)-6-[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]-7-[3,4,5-trihydroxy-6-(hydroxymethyl)oxan-2-yl]oxychromen-4-one}, a flavone found in young green barley leaves, is known to possess antioxidant, antidiabetic, and hepatoprotective effects. In the present study, the anti-inflammatory, anti-allergic, and skin-protective effects of saponarin were investigated to evaluate its usefulness as a functional ingredient in cosmetics. In lipopolysaccharide-induced RAW264.7 (murine macrophage) cells, saponarin (80 μM) significantly inhibited cytokine expression, including tumor necrosis factor (TNF)-α, interleukin (IL)-1β, inducible nitric oxide synthase, and cyclooxygenase (COX)-2. Saponarin (80 μM) also inhibited the phosphorylation of extracellular signal-regulated kinase (ERK) and p38 involved in the mitogen-activated protein kinase signaling pathway in RAW264.7 cells. Saponarin (40 μM) significantly inhibited β-hexosaminidase degranulation as well as the phosphorylation of signaling effectors (Syk, phospholipase Cγ1, ERK, JNK, and p38) and the expression of inflammatory mediators (tumor necrosis factor [TNF]-α, IL-4, IL-5, IL-6, IL-13, COX-2, and FcεRIα/γ) in DNP-IgE- and DNP-BSA-stimulated RBL-2H3 (rat basophilic leukemia) cells. In addition, saponarin (100 μM) significantly inhibited the expression of macrophage-derived chemokine, thymus and activation-regulated chemokine, IL-33, thymic stromal lymphopoietin, and the phosphorylation of signaling molecules (ERK, p38 and signal transducer and activator of transcription 1 [STAT1]) in TNF-α- and interferon (IFN)-γ-stimulated HaCaT (human immortalized keratinocyte) cells. Saponarin (100 μM) also significantly induced the expression of hyaluronan synthase-3, aquaporin 3, and cathelicidin antimicrobial peptide (LL-37) in HaCaT cells, which play an important role as skin barriers. Saponarin remarkably inhibited the essential factors involved in the inflammatory and allergic responses of RAW264.7, RBL-2H3, and HaCaT cells, and induced the expression of factors that function as physical and chemical skin barriers in HaCaT cells. Therefore, saponarin could potentially be used to prevent and relieve immune-related skin diseases, including atopic dermatitis.

<p class="Abstract">In this study, the anti-inflammatory potential of <em>Anredera </em>cordifolia and <em>Piper </em>crocatum extracts on lipopolysaccharide-induced murine macrophage cell line (RAW 264.7) was observed. Cell viability assay was performed with MTS assay. Parameters measured to determine the anti-inflammatory activity were interleukin-1β (IL-1β), tumor necrosis factor (TNF)-α, nitric oxide (NO) and IL-6. Both <em>A. </em>cordifolia and<em> P. </em>crocatum at concentration of 50 µg/mL in cell line resulted significant decrease in TNF-α level (250.3 and 242.5 pg/mL respectively). <em>A. </em>cordifolia showed significant decrease in IL-1β level at 50 µg/mL and IL-6 level at 10 µg/mL, whilst <em>P. </em>crocatum  showed significant decrease IL-1β level in three concentrations with lowest level at 50 µg/mL.<em> A. </em>cordifolia showed lowest decrease in NO level at 50 µg/mL but not comparable with normal cells, whilst <em>P. </em>crocatum showed significant decrease in NO level at 50 µg/mL. This research revealed that <em>A. </em>cordifolia and<em> P. </em>crocatum possess the anti-inflammatory potential indicated by the inhibitory activity of the inflammatory mediators including, TNF-α, IL-1β, IL-6, and NO.</p>

Background:In aromatherapy, essential oils are used as anti-inflammatory remedies, but experimental studies on their action mechanisms are very limited.Aims:To assess their anti-inflammatory activities, effects of essential oils on neutrophil activation were examinedin vitro.Methods:Neutrophil activation was measured by tumor necrosis factor-alpha (TNF-α)-induced adherence reaction of human peripheral neutrophils.Results:All essential oils tested at 0.1% concentration suppressed TNF-α-induced neutrophil adherence, and, in particular, lemongrass, geranium and spearmint oils clearly lowered the reaction even at 0.0125%. Similar inhibitory activities for the neutrophil adherence were obtained by their major constituent terpenoids: citral, geraniol, citronellol and carvone. In contrast, very popular essential oils, tea tree oil and lavender oil, did not display the inhibitory activity at the concentration.Conclusion:Thus, some essential oils used as anti-inflammatory remedies suppress neutrophil activation by TNF-α at a low concentration (0.0125-0.025%)in vitro.

The topical anti-inflammatory activity of the essential oil of Myrtus communis L. was studied using croton oil induced ear edema and myeloperoxidase (MPO) activity in mice, and cotton pellet induced granuloma, and serum tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) in rats. On topical application, the oil exhibited a significant decrease in the ear edema as well as MPO activity. The oil also inhibited cotton pellet-induced granuloma and serum TNF-α and IL-6. It can be concluded that the essential oil of Myrtus communis reduces leukocyte migration to the damaged tissue and exhibits anti-inflammatory activity.

 Objective: The main objective of this study was to assess tumor necrosis factor-α (TNF)-α and cyclooxygenase enzymes (COX) inhibition potency of Tamarindus indica Linn. in comparison to standard drug (indomethacin).Methods: Three plants are selected for the studies, namely: Aloe vera (L.), Terminalia chebula Reitz., and T. indica Linn. Estimation of TNF-α in serum (at 1:10 dilution in PBS) was performed using the immunoenzymatic (ELISA) technique. COX inhibitor screening assay kits were used for estimation of COX.Result: All three plant extracts showed a potent significant inhibition of the COX enzyme as compared to the positive control and standard drug when the animal was administered with 400 mg/kg. These studies indicate that the T. indica plant extract showed significant COX inhibition even at low dose. All the extracts were effective anti-inflammatory in nature, however, T. indica extracts at a dose of 400 mg/kg were found to be most potent. It was found to be comparable with that of Indomethacin 10 mg/kg body weight.Conclusion: The anti-inflammatory activity expressed by all the three plants A. vera (L.), T. chebula Reitz., and T. indica L. Among all three plants T. indica (L) was found to be more active against both TNF-α and COX, and it was comparable to standard drug Indomethacin. Need further studies to elucidate the exact secondary metabolite by which these plants express this activity.

Background: This study involves the investigation of spontaneous and induced secretion of the pro-inflammatory cytokine tumor necrosis factor-α (TNF-α) and the anti-inflammatory chemokine C-C motif chemokine ligand 18 (CCL18) by monocytes isolated from blood of patients with long-term type 2 diabetes mellitus (T2DM), both with or without foot ulcers. Methods: A total of 121 patients with T2DM (79 without diabetic foot syndrome (DFS) and 42 patients with DFS) were included. Cluster of Differentiation 14 (CD14+) monocytes were isolated from patients’ blood and stimulated by interferon-γ (IFN-γ) and interleukin-4 (IL-4) for induction of pro- and anti-inflammatory monocyte activation, respectively. The concentrations of TNF-α and CCL18 in the culture medium were measured using ELISA on day 1 and day 6 after cell stimulation. Results: We found a correlation between glycated hemoglobin (HbA1c) and stimulated secretion levels of TNF-α (r = 0.726, p = 0.027) and CCL18 (r = –0.949, p = 0.051) in patients with DFS. There was an increase of pro- and anti-inflammatory activation of monocytes in all patients with different durations of DFS (p < 0.05). However, no stimulation of anti-inflammatory activation was detected in patients with DFS lasting more than 6 months (p = 0.033). Conclusions: Our study showed an increase in pro-inflammatory secretion and a decrease in anti-inflammatory secretion by monocytes isolated from blood of patients with T2DM depending on HbA1c levels and duration of the inflammatory process. These findings allow us to assume that monocytes isolated from T2DM patients are characterized by a biased ability to respond towards pro-inflammatory stimulation, contributing to the chronic wound process.

Teucrium polium leaf is one of the folkloric medicinal plants used traditionally to treat many diseases in the Palestinian community. It has antibacterial antioxidant and anti-inflammatory consequences. Present study aims the evaluating the in vitro inhibitory effect of Teucrium polium leaf extracts on tumor necrosis factor-α (TNF-α) using polymorphonuclear cells (PMNCs), in addition to determine its antioxidant and total phenolic and flavonoids contents. Polymorphonuclear cells were withdrawn from whole blood according to Histopaque (Ficol-1077) method. Blood cells were cultured in an enriched Roswell Park Memorial Institute (RBMI) medium. The levels of tumor necrosis factor (TNF-α) were determined after 24 h using LPS stimulation. Total phenolic contents, flavonoids contents and antioxidant activity were measured using spectrophotometric method. The TNF-α concentrations were compared using paired-samples t test. The leaf extracts of Teucrium polium revealed significant reduction in terms of TNF-α levels. The extract contained high phenolic and flavonoids contents and its antioxidant activities were remarkable. The reduced values in the TNF-α levels as affected by Teucrium polium leaf extracts indicate its effect in anti-inflammation. The plant is rich with polyphenolic compounds and flavonoids and has strong antioxidant activity. The observed anti-inflammatory effect of the extracts under study may be discussed as the influence of the significant presence of the phenolic compounds and flavonoids.

Urera aurantiaca is an Argentinean medicinal and edible species traditionally used to treat symptoms of inflammation. The aim of this study was to evaluate the anti-inflammatory activity of a methanol extract and its major compound. U. aurantiaca aerial parts were extracted with methanol by maceration. A phytochemical analysis was performed, and the extract’s major component, apigenin-7-glucuronide (A7G), was identified by spectroscopic and HPLC methods. The analysis of the inflammatory mediators nitric oxide (NO) and tumor necrosis factor alpha (TNF-α) in lipopolysaccharide- (LPS-) stimulated macrophages were used in the evaluation of the extract and the major compound anti-inflammatory effects. The extract reduced LPS-augmented NO release from 100 μg/mL (27%), reaching the highest inhibition at 1000 μg/mL (96.3%), while A7G reduced it 30.7% at 1 μg/mL, and its maximum effect was 97.1% at 10 μg/mL. In the TNF-α model, the extract at 500 and 1000 μg/mL reduced LPS-augmented TNF-α by 13.5% and 93.9%, respectively; meanwhile, A7G reduced it by 26.2% and 83.8% at 5 and 10 μg/mL, respectively. U. aurantiaca popular use was validated. In the present study, for the first time, A7G was isolated from U. aurantiaca; furthermore, A7G showed anti-inflammatory effect in the macrophage cell line RAW264.7 (ATCC) and seems to be responsible for the extract anti-inflammatory effect.

ABSTRACT Azithromycin (AZM) ameliorates lung function in cystic fibrosis (CF) patients. This macrolide has been suggested to have anti-inflammatory properties as well as other effects potentially relevant for therapy of CF. In this study, we utilized three CF (IB3-1, 16HBE14o- AS3, and 2CFSMEo-) and two isogenic non-CF (C38 and 16HBE14o- S1) airway epithelial cell lines to investigate whether AZM could reduce tumor necrosis factor alpha (TNF-α) mRNA and protein levels by real-time quantitative PCR analysis and an enzyme-linked immunosorbent assay (ELISA), respectively. We studied the effects on the DNA binding of NF-κB and specificity protein 1 (Sp1) by an ELISA. Non-CF cells express significantly lower TNF-α mRNA and protein levels than an isogenic CF cell line. In CF cells, AZM treatment causes a 30% reduction of TNF-α mRNA levels (P < 0.05) and a 45% decrease in TNF-α secretion (P < 0.05), reaching approximately the levels of the untreated isogenic non-CF cells. In CF cells, NF-κB and Sp1 DNA binding activities were also significantly decreased (about 45 and 60%, respectively; P < 0.05) after AZM treatment. Josamycin, a macrolide lacking clinically described anti-inflammatory effects, was ineffective. Finally, AZM did not alter the mRNA expression levels of interleukin-6, a proinflammatory molecule not differentially expressed in CF and isogenic non-CF cells. The results of our study support the anti-inflammatory activities of this macrolide, since we show that AZM reduced the levels of TNF-α and propose inhibitions of NF-κB and Sp1 DNA binding as possible mechanisms of this effect.
