Lutein is a naturally occurring carotenoid with antioxidative, antitumorigenic, antiangiogenic, photoprotective, hepatoprotective, and neuroprotective properties. Although the anti-inflammatory effects of lutein have previously been described, the mechanism of its anti-inflammatory action has not been fully elucidated. Therefore, in the present study, we aimed to investigate the regulatory activity of lutein in the inflammatory responses of skin-derived keratinocytes or macrophages and to elucidate the mechanism of its inhibitory action. Lutein significantly reduced several skin inflammatory responses, including increased expression of interleukin-(IL-) 6 from LPS-treated macrophages, upregulation of cyclooxygenase-(COX-) 2 from interferon-γ/tumor necrosis-factor-(TNF-)α-treated HaCaT cells, and the enhancement of matrix-metallopeptidase-(MMP-) 9 level in UV-irradiated keratinocytes. By evaluating the intracellular signaling pathway and the nuclear transcription factor levels, we determined that lutein inhibited the activation of redox-sensitive AP-1 pathway by suppressing the activation of p38 and c-Jun-N-terminal kinase (JNK). Evaluation of the radical and ROS scavenging activities further revealed that lutein was able to act as a strong anti-oxidant. Taken together, our findings strongly suggest that lutein-mediated AP-1 suppression and anti-inflammatory activity are the result of its strong antioxidative and p38/JNK inhibitory activities. These findings can be applied for the preparation of anti-inflammatory and cosmetic remedies for inflammatory diseases of the skin.

The present study was undertaken to formulate and evaluate the anti-inflammatory, anti-oxidant and anti-angiogenic activities of nanoemulsion of Memecylaene.  Memecylaene was isolated from the leaves of Memecylon malabaricum by using various chromatographic methods. An oil-in-water (O/W) nanoemulsion of Memecylaene was formulated by sonication method using sunflower oil (oil phase), Tween 80 (Surfactant) and Ethanol (co-surfactant). The prepared nanoemulsion was characterized for its droplet size, poly dispersity index and zeta potential. Stability studies were performed and the nanoemulsions were subjected to different biological activities. The formulated nanoemulsion had a particle size range of 52.02 nm to 59.47 nm and zeta potential of -1.27 mV. The enhanced activity of Memecylaene, encapsulated in O/W emulsions is evidenced by the inhibition of phospholipase (PLA2) enzyme and H+, K+ -ATPase and thus showing anti-inflammatory and anti-secretagogues effects. The in vitro anti-oxidant activity was evaluated by DPPH radical and Nitric oxide radical scavenging activity. Further, the inhibition of the growth of neo vessels formation in the in-vivo model system of chick chorioallantoic membrane (CAM) assay, which is angiogenesis dependent, was also observed. The above findings would help in understanding the putative potential of Memecylaene-loaded nanoemulsion as a therapeutic agent.

Clerodendrum phlomid is was a common shrub of arid plains, low hills, and tropical deserts. It belongs to the family Verbenaceae. Many species of this genus have been documented in traditional system of medicine in India. The roots of the plant have been extensively studied in Ayurveda but in folk and traditional medicine, it is the leaf that finds more application in alleviating many diseases. Oxidation byproducts of metabolism was responsible for many pathophysiological conditions. Anti-oxidants are molecules that quench the free radicals. The present study aims at evaluating the in-vitro anti-oxidant and anti-inflammatory activity of the aqueous and ethanol leaf extract of Clerodendrum phlomidis. The anti-oxidant activity was evaluated by three in vitro models, namely the DPPH radical scavenging activity, hydroxyl radical scavenging activity and NO radical scavenging activity. The anti-inflammatory activity was evaluated by the RBC membrane Inhibition method. The aqueous extract was found to have better anti- oxidant activity than the ethanol extract in DPPH and NO radical scavenging activity. The RBC membrane inhibition method clearly states that the aqueous leaf extract of Clerodendrum phlomidis was found to have a comparatively an effective anti-inflammatory activity than ethanol extract.

AbstractOur present study was carried out to explore the potential role of the methanol extract from the leaves ofMethanol extracts of PT leaves were prepared using 500 g powder in 1.8 L methanol by percolation method, followed by evaporation in a rotary evaporator under controlled temperature and pressure. The crude methanol extract was dried by freeze drier and preserved at 4 °C.Oral administration of PT significantly (p<0.05) increased the reaction time at 55.73% (250 mg/kg) and 72.81% (500 mg/kg) inhibition (p<0.05) in the hot plate test at 3 h. PT significantly (p<0.05) inhibited 42.17% (250 mg/kg) and 56.63% (500 mg/kg) acetic acid-induced writhing. PT leaves (250 and 500 mg/kg) also significantly (p<0.05) inhibited paw edema 6 h after carrageenan injection. Furthermore, this plant showed significant (p<0.05) free radical-scavenging activity at a dose range of 25–800 μg/mL.Based on the findings, we can conclude that PT leaf possesses analgesic, anti-inflammatory, and anti-oxidant activities. Preliminary phytochemical study of PT leaves revealed the presence of flavonoids, tannins and triterpens in methanol extract which could be correlated with its observed biological activities.

Background: Spices and herbs are known to have anti-oxidant and anti-inflammatory properties. We studied their properties of Namya Kanom Jeen (NKJ), a spicy soup (Southern Thailand recipe) with water and ethanol (50% and 95%) extracts.Methods: This study aimed to assess functional properties of NKJ powder extract using in vitro model. These functional properties were anti-oxidant, α-amylase inhibition, and anti-inflammatory properties. Anti-oxidant activities were determined using free radical scavenging activity (DPPH) and Ferric Reducing Anti-oxidant Power (FRAP). Anti-inflammation effect was studied by measuring nitric oxide (NO) production inhibition on RAW264.7 macrophage cells after being exposed to lipopolysaccharide (LPS). Results: Water extract of NKJ powder demonstrated the highest activity in anti-inflammatory and anti-oxidant property by DPPH radical scavenging activity when compared with ethanol extract. Conclusion: NKJ powder extracts may ameliorate the oxidation and inflammation conditions which would be the combined effect of several bioactive compounds from many of the ingredients within these extracts.Keywords: Anti-oxidant; Anti-inflammation; Phenolic compound; Namya Kanom Jeen powder

The current treatment options for inflammatory bowel disease (IBD) are unsatisfactory. Therefore, novel and safer therapies are needed. We previously reported that koreanaside A (KA) showed high radical scavenging activity and suppressed vascular cell adhesion molecule 1 (VCAM-1) expression in vascular smooth muscle cells. However, the molecular mechanisms involved in its anti-inflammatory effect have not been reported. KA inhibited pro-inflammatory mediators such as inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), nitric oxide (NO), and prostaglandin E2 (PGE2). KA inhibited the production and mRNA expression of interleukin (IL)-6 and tumor necrosis factor-α (TNF-α) induced by LPS. KA downregulated the myeloid differentiation primary response 88 (MyD88)-dependent inflammatory gene expressions in the MyD88-overexpressed cells. KA suppressed the LPS-induced transcriptional and DNA-binding activities of activator protein-1 (AP-1) and nuclear factor-kappa B (NF-κB). KA was found to inhibit the phosphorylation of Janus kinase 1/2 (JAK1/2) and signal transducers and activators of transcription 1/3 (STAT1/3). In DSS-induced colitis mice, KA relieved the symptoms of colitis by suppressing inflammatory cell infiltration, restoring tight junction (TJ)- and epithelial–mesenchymal transition (EMT)-related protein expression, and inactivating AP-1, NF-κB, and STAT1/3. Therefore, KA reduced inflammatory responses by downregulating AP-1, NF-κB, and JAK/STAT signaling in LPS-induced macrophages and DSS-induced colitis mice.

Porphyra tenera (laver) has long been a popular and traditional seaweed food in Korea, Japan, and China. Historically, it was known as a marine medicinal herb to treat hemorrhoids and cholera morbus in Donguibogam. We investigated the effects of P. tenera extract (PTE) for its antioxidant and anti-inflammatory activities. These activities were measured using assays for 2,2-diphenyl-1-picrylhydrazyl (DPPH) and nitric oxide (NO) radical scavenging and its superoxide dismutase- (SOD-) like activity, and through the inhibitory production of inflammatory mediators (prostaglandin E2 (PGE2), NO, tumor necrosis factor alpha (TNF-α), and interleukin-6 (IL-6)) in lipopolysaccharide- (LPS-) stimulated Raw 264.7 cells. The antioxidant assay results showed that PTE displayed DPPH radical scavenging activity (46.44%), NO radical scavenging activity (67.14%), and SOD-like activity (80.29%) at a concentration of 5 mg/mL. In the anti-inflammatory assays, treatment with PTE (1 mg/mL) significantly inhibited expression levels of LPS-induced COX-2 and iNOS, as well as the production of PGE2, NO, TNF-α, and IL-6. These results show that PTE has antioxidant and anti-inflammatory properties and provide scientific evidence to explain the antioxidative and anti-inflammatory properties of PTE.

Beneficial antioxidant phytochemicals are found in many medicinal plants.Pseuderanthemum palatiferum(PP), a well-known Vietnamese traditional medicinal plant in Thailand, has long been used in folk medicine for curing inflammatory diseases, often with limited support of scientific research. Therefore, this study aimed to determine antioxidant and modulation of inflammatory mediators of ethanol and water extracts of PP (EEP and WEP, resp.). WEP had significantly higher phenolic and flavonoid levels and DPPH radical scavenging activity than EEP. However, EEP exhibited greater reducing power than WEP. A greater decrease oftert-butyl hydroperoxide-induced oxidative stress in RAW264.7 macrophage cells was also observed with EEP. Modulation of inflammatory mediators of EEP and WEP was evaluated on LPS plus IFN-γ-stimulated RAW264.7 cells. EEP more potently suppressed LPS plus IFN-γ-induced nitric oxide (NO) production than WEP. Both EEP and WEP also suppressed the expression of iNOS and COX-2 protein levels. Collectively, these results suggest that PP possesses strong antioxidant and anti-inflammatory properties.

The genus Curcuma is part of the Zingiberaceae family, and many Curcuma species have been used as traditional medicine and cosmetics in Thailand. To find new cosmeceutical ingredients, the in vitro anti-inflammatory, anti-oxidant, and cytotoxic activities of four Curcuma species as well as the isolation of compounds from the most active crude extract (C. aromatica) were investigated. The crude extract of C. aromatica showed 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity with an IC50 value of 102.3 μg/mL. The cytotoxicity effect of C. aeruginosa, C. comosa, C. aromatica, and C. longa extracts assessed with the 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide (MTT) assay at 200 μg/mL were 12.1 ± 2.9, 14.4 ± 4.1, 28.6 ± 4.1, and 46.9 ± 8.6, respectively. C. aeruginosa and C. comosa presented apoptosis cells (57.7 ± 3.1% and 32.6 ± 2.2%, respectively) using the CytoTox-ONE™ assay. Different crude extracts or phytochemicals purified from C. aromatica were evaluated for their anti-inflammatory properties. The crude extract of C. aromatica showed the highest potential to inhibit NF-κB activity, followed by C. aeruginosa, C. comosa, and C. longa, respectively. Among the various purified phytochemicals curcumin, germacrone, curdione, zederone, and curcumenol significantly inhibited NF-κB activation in tumor necrosis factor (TNF) stimulated HaCaT keratinocytes. Of all compounds, curcumin was the most potent anti-inflammatory.
