  • A series of structurally diverse amide derivatives of [6-(3,5-dimethyl-4- chloro-pyrazole-1-yl)-3(2H)-pyridazinone-2-yl]acetic acid were prepared and tested for their in vivo analgesic and anti-inflammatory activity by using p-benzoquinone-induced writhing test and carrageenan induced hind paw edema model, respectively. The analgesic and anti-inflammatory activity of the compounds, 7c, 7d and 7k were found to be equipotent to aspirin (as an analygesic) and indometacin (as an anti-inflammatory drug), respectively. The other amide derivatives generally resulted in lower activity on comparision with reference compounds.

  • The fruit of the black raspberry (Rubus coreanus Miquel) has been employed in traditional medicine, and recent studies have demonstrated its measureable biological activities. However, the root of the black raspberry has not been studied. Therefore, in this study, we evaluated the anti-inflammatory and antibacterial properties of the root and unripe fruit polyphenols of the black raspberry. Both polyphenols proved to have anti-inflammatory activity as evidenced by the decreased nitric oxide (NO), cytokines (IL-$1{\beta}$, IL-6, and IL-10) and prostaglandin E2 ($PGE_2$) levels in lipopolysaccharide (LPS)-stimulated RAW 264.7 murine macrophages. However, root polyphenols showed stronger anti-inflammatory activity than fruit polyphenols. LPS-induced mRNA and protein expressions of inducible NO synthase (iNOS) and cyclooxygenase (COX)-2 levels were also decreased, confirming the anti-inflammatory activity. Root polyphenols showed lethal activity against methicillin-resistant Staphy-lococcus aureus (MRSA), carbapenem-resistant Acinetobacter baumannii (CRAB), and Bacillus anthracis. In contrast, the black raspberry fruit did not demonstrate these properties. These data provide the first demonstration that black raspberry root has potential anti-inflammatory and anti-superbacterial properties that can be exploited as alternatives for use in the food and cosmetic industries and/or as pharmaceuticals.

  • Objectives : Allergic diseases have a various symptoms of hyperresponsiveness and recently hyperresponsive reaction in the chronic phase is reported as the important mechanisms. Cheonggisan(CGS) is used in oriental clinics for curing various skin diseases due to effect of controlling of pruritus. There have been studies on the anti-allergic effect and anti-inflammatory effect of CGS, but there had no study of anti-allergic effects in allergic late inflammation of CGS, so we aimed to find out the effects of CGS in allergic late inflammation in our study.Methods : To investigate the anti-allergy effect and anti-inflammatory effect of CGS, RAW 264.7 macrophage cells and CSG water-extracts were used. Cytotoxic effect of CSG was examined by MTT assay, an oxidative product of NO was measured in the culture medium by the Griess reagent assay. The level of prostaglandin E2(PGE2) was measured by competitive enzyme-linked immunoassay. Cytokine(PGE2, IL-1β, IL-6, TNF-α) was measured by Bio-Plex suspension assay system and quantitative multiplexed cytokine/chemokine assay.Results : We investigated that there was no cytotoxic effect of CGS water-extract at any levels of concentration on RAW 264.7 macrophage cells by MTT assay. CGS water-extracts significantly suppressed the levels of the inflammatory mediators such as NO and PGE2, cytokine of IL-1β, TNF-α at the level of 400 ㎍/㎖ CGS concentration. But there was no significant effect on IL-6 production suppression.Conclusions : These results suggest that CSG water-extract has and anti-inflammatory effects in allergic reaction. These properties may contribute to the allergic diseases and inflammatory related disease care.

  • Soy sauce is one of the representatives of traditional fermented foods in Korea. However, studies on soy sauce are relatively insufficient in Korea compared to Japan. In this study, antioxidant and anti-inflammatory activities of polysaccharides were measured by polysaccharides isolated from two different soy sauces, Korean and Japanese (KSS-0 and JSS-0). KSS-0 was purified into two fractions using gel chromatography and named them as KSS-I and KSS-II. To investigate the antioxidant activity of the polysaccharides, we measured the polyphenol content and radical scavenging activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS). To investigate the anti-inflammatory activity of polysaccharides, we used RAW 264.7 macrophage cells and induced inflammation using lipopolysaccharide (LPS). Then, we measured levels of inflammatory mediators such as nitric oxide (NO) and tumor necrosis factor (TNF)-α. Among the four polysaccharides, KSS-II showed the highest antioxidant activity and had good anti-inflammatory activity; KSS-II decreased inflammatory mediators in a dose-dependent manner. In conclusion, the polysaccharide isolated from Korean soy sauce (KSS-II) showed better anti-oxidant and anti-inflammatory activities than polysaccharides isolated from Japanese soy sauce, and may be useful as substances for functional foods.

  • Purpose: This study was performed to evaluate anti-thrombotic and anti-inflammatory effects of NeungaSoJeokTang water extract (NSJT). Methods: In the study of anti-inflammatory effects, NSJT was investigated using cultured cells and murine models. As for the parameters of inflammation, levels of several inflammatory cytokines and chemical mediators which are known to be related to inflammation were determined in mouse lung fibroblast cells(mLFC) and RAW 264.7 cells. Results: Prior to the experiment, we evaluated sGOT, sGPT, BUN and creatine after the treatment. As a result, NSJT was innoxious on liver and kidney. In experiment of anti-thrombotic effect, NSJT inhibited the platelet aggregation induced by ADP and epinephrine, and inhibited pulmonary embolism induced by collagen and epinephrine. NSJT did not affect significantly the blood flow rate both in vitro and in vivo. NSJT increased platelet number and fibrinogen amount, and NSJT shortened PT and APTT in thrombus model induced by dextran. In experiment of anti-inflammatory effect, NSJT inhibited $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, COX-2 and NOS-II mRNA expression in a concentration-dependent manner in RAW 264.7 cell line, and inhibited significantly NO production at 50, 100 ${\mu}g/ml$, and also inhibited ROS production in a concentration-dependent manner. NSJT inhibited $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production significantly in serum of acute inflammation-induced Balb/c mice, and decreased $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production in spleen tissue, but increased $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ production in liver tissue. NSJT increased survival rate at the 3th day in ICR mice with lethal endotoxemia induced by LPS. Conclusion: These results suggest that NSJT can be used for treating diverse female diseases caused by thrombosis and inflammation such as pelvic pain, pelvic inflammatory disease as well as vulvar pain due to vulvitis, vulvar vestibulitis and so on.

  • Objectives : The aerial parts of Rumex japonicus Houtt. (RF) is used by traditional clinics to treat parasite infection in East asia. This study aims a verification of anti-oxidative and anti-inflammatory effects of RF methanol extract. Methods : Anti-oxidative effects of RF were measured by scavenging activities of DPPH, superoxide, nitric oxide (NO) and peroxynitrite radicals. And also scavenging activities of anti-oxidation in lipopolysaccharide (LPS)-treated RAW 264.7 cells were measured. The inhibitory effects against the production of inflammatory mediators including NO, prostaglandin $E_2$ ($PGE_2$), tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-$1{\beta}$ (IL-$1{\beta}$), IL-6, inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), and the translocation of nuclear factor (NF)-${\kappa}B$ in LPS-stimulated RAW 264.7 cells by RF were tested. Results : RF scavenged DPPH, superoxide, NO and peroxynitrite radicals, and RF (at $200{\mu}g/m{\ell}$) reduced the inflammatory mediators definitely. Conclusions : These results indicate that RF may be a potential drug source for oxidative stress related inflammatory diseases.

  • In this study, we determined the anti-inflammatory activity and mechanism of action of a hexane fraction (hWRF) obtained from white Rosa hybrida flowers by employing various assays such as quantitative real-time PCR, Western blotting, and Electrophoretic-Mobility Shift Assay (EMSA). The results revealed that the hWRF had excellent anti-inflammatory potency by reducing inflammatory repertoires, such as inducible nitric oxide synthase (iNOS), interleukin-$1{\beta}$, and cyclooxygenase-2 (COX-2) in RAW264.7 cells when stimulated with lipopolysaccharide (LPS), a pro-inflammatory mediator. The reduction of nitric oxide (NO) release from RAW 264.7 cells supported the anti-inflammatory effect of hWRF. Interestingly, hWRF effectively inhibited LPS-mediated nuclear factor-${\kappa}B$ (NF-${\kappa}B$) p65 subunit translocation into the nucleus and extracellular signal-regulated kinase (ERK)1/2 phosphorylation, suggesting that hWRF anti-inflammatory activity may be based on inhibition of the NF-${\kappa}B$ and MAPK pathways. Based on the findings described in this study, hWRF holds promise for use as a potential anti-inflammatory agent for either therapeutic or functional adjuvant purposes.

  • Sanyeoleumja (SY) is the traditional Korean medicinal prescription for the treatment of inflammatory diseases of eyes. In this study, the anti-inflammatory effects of SY water extract were investigated. To measure the anti-inflammatory effects of SY, we examined the productions of inflammatory factor including nitric oxide (NO), prostaglandin E2 (PGE2), inducible nitric oxide synthase (iNOS), cyclooxygenase-2 (COX-2), interleukin-6 (IL-6), interleukin-1β (IL-1β) in lipopolysaccharide (LPS)-induced RAW 264.7 cells. SY inhibited NO and PGE2 production in a dose dependent manner and decreased the protein and mRNA expression of iNOS and COX-2. Also, SY decreased the mRNA expression of interleukin-6 (IL-6) and interleukin-1β (IL-1β). In conclusion, SY downregulated LPS-induced inflammatory factor productions, which could be a clinical basis for inflammatory diseases.

  • Talipariti hamabo is a plant growing around salt marshes in the Lava Coast region of Jeju Island, Korea. In this study, the extract of T. hamabo leaves was investigated for the anti-inflammatory, anti-oxidative and anti-bacterial activities and their active constituents were identified. In the anti-inflammatory tests using lipopolysaccharide-stimulated RAW264.7 cells, the ethyl acetate (EtOAc) fraction inhibited the nitric oxide production without causing cell toxicity. Moreover, the EtOAc fraction reduced pro-inflammatory cytokines (tumor necrosis factor-α, interleukin-6) as well as prostaglandin E2. In the anti-oxidative studies with DPPH and ABTS+ radicals, potent scavenging activities were observed in the EtOAc and n-butanol fractions. Upon the anti-bacterial tests using Staphylococcus epidermidis, EtOAc and n-butanol fractions exhibited good activities. Through the phytochemical studies on EtOAc fraction, three components were isolated by repeated column chromatography; oleic acid (1), p-hydroxyphenethyl-trans-ferulate (2), nicotiflorine (3). Based on these results, the extract of T. hamabo leaves can be developed as natural resources for cosmetic applications.
