  • In the present study, we investigated the effect of the water extract of Perilla frutescens var. acuta (Labiatae; WEPF) on the mast cell-mediated allergic reactions. WEPF was anally administered to mice for high and fast absorption. WEPF inhibited compound 48/80-induced systemic allergic reaction. WEPF attenuated immunoglobulin E (IgE)-mediated local allergic reaction. In addition, WEPF decreased the gene expression of pro-inflammatory cytokines in phorbol 12-myristate 13-acetate plus calcium ionophore A23187 (PMACI)-stimulated HMC-1 cells. These results indicate that WEPF inhibits mast cell-mediated allergic reactions in vivo and in vitro.

  • A new method for felbinac, which is a potent anti-inflammatory agent, is described. Friedel-Crafts reaction of biphenyl with ethyl ${\alpha}-chloro-{\alpha}-(methylthio)acetate(1)$ afforded ethyl 2-methylthio-2-(4-biphenylyl)acetate(4). Felbinac (7) was synthesized by desulfurization of compound (4) with zinc dust in acetic acid, followed by hydrolysis of the resultant ethyl 2-(4-biphenylyl)acetate (6).

  • A new synthetic method for tiaprofenic acid, which is a potent anti-inflammatory agent, was described. Friedel-Crafts reaction of thiophene with ethyl ${\alpha}-chloro-{\alpha}-(methylthio)$ acetate (1) gave ethyl ${\alpha}-methylthio-2-thiopheneacetate$ (3). Ethyl ${\alpha}-methyl-2-thiopheneacetate$ (5) was prepared by treatment of (3) with NaH and MeI, followed by desulfurization with zinc dust-acetic acid of the resultant ethyl ${\alpha}-methyl-{\alpha}-methylthio-2-thiopheneacetate$ (4). Tiaprofenic acid (7) could be easily synthesized by benzoylation of (5) and hydrolysis of the resultant ethyl $5-benzoyl-{\alpha}-methyl-2-thiopheneacetate$ (6).

  • The purpose of this research was to investigate effects of Bangpoongtongsungsan water extract(BTSE) on the immune reaction, anti-allergy action and anti-inflammatory action in BALB/c mice. The administration of BTSE (500mg/kg) enhanced the cell viability of thymocytes and the population of helper T cells in splenic T-lymphocytes. BTSE suppressed the production of nitric oxide, but enhanced the phagocytic activity in peritoneal macrophages. BTSE enhanced hemagglutination titer in mice. BTSE inhibited passive cutaneous anaphylaxis induced by egg albumin in rat, the lethal anaphylaxis induced by platelet activating factor and compound 48/80 in mice, and then inhibited the degranulation of peritoneal mast cells induced by compound 48/80. BTSE did not inhibit Arthus reaction, but inhibited the delayed type hypersensitivity induced by SRBC and contact dermatitis induced by DNFB. BTSE inhibited the acute hind paw edema induced by histamine after 30 minutes, the permeability of evans blue into peritoneal cavity induced by acetic acid and the writhing syndrome induced by acetic acid. These results suggest that BTSE has an immunopotentiative action, anti-allergy action and anti-inflammatory action via the inhibition of histamine release.

  • The mast cell-mediated immediate-type allergic reaction is involved in many allergic diseases such as asthma, allergic rhinitis, and sinusitis. The discovery of drugs for the treatment of mast cell-mediated immediate-type allergic diseases is a very important subject in human health. In this study, we investigated the effect of small black soybean (Glycine max Merr.) (Leguminosae) on mast cell-mediated allergic reaction and pro-inflammatory cytokine secretion. Small black soybean (SBS) inhibited compound 48/80-induced systemic reaction. SBS attenuated immunoglobulin (Ig) E-mediated local allergic reaction. In addition, SBS decreased the phorbol 12-myristate 13-acetate plus calcium ionophore A23187-stimulated tumor necrosis factor $(TNF)-{\alpha}$ and interleukin (IL)-8 secretion in human mast cells. These results indicate that SBS may be beneficial in the treatment of mast cell-mediated immediate-type allergic reactions.

  • A concise synthesis of flurbiprofen, a member of the non-steroidal anti-inflammatory 2-arylpropionic acids, has been accomplished. The key feature of this synthesis involves successive palladium-catalyzed cross coupling reactions. In particular, a 2-arylacylate intermediate, which easily converted to the key 2-arylpropionic acid scaffold, was afforded by a versatile palladium-catalyzed cross coupling reaction between diazopropanate and bisphenylboronic acid. This synthetic procedure would facilitate synthesis of the flurbiprofen and anti-inflammatory 2-arylpropionic acid derivatives.

  • Objective : Nypa fruticans Wurmb. Fruit (NF) has been used as a conventional medicine to treat inflammatory peridontal diseases in Myanmar and Eastern Asia. However, the anti-inflammatory effect of NF aqueous extract on lipopolysaccharide (LPS)-induced inflammatory responses was not well-investigated. Therefore, this study was aimed to investigate the anti-inflammatory effect of NF on LPS-induced inflammatory responses on RAW 264.7 cells.Methods : To induce inflammation on the macrophage cell line, RAW 264.7 cells were treated with 500 ng/mL of LPS. Water extracts of NF was treated 1 h prior to treatment of LPS. Cell viability was measured by MTT assay. Production of nitrite was measured with Griess assay and pro-inflammatory cytokines such as interleukine (IL)-1β and IL-6, and tumor necrosis factor (TNF)-α was measured by enzyme-linked immunosorbent assay (ELISA) and real-time polymerase chain reaction (PCR). In addition, we examined the inhibitory mechanisms of NF by western blot and immunocytochemistry.Result : Water Extract from NF itself did not have any cytotoxic effect at the concentration of 200 ㎍/ml in RAW 264.7 cells. Treatment of NF inhibited the production of nitrite, and pro-inflammatory cytokines inlcuding IL-1β, IL-6 and TNF-α in a dose dependant. In addition, NF treatment inhibited the LPS-induced activation and translocation of nuclear factor (NF)-κB.Conclusion : In summary, our result suggest that treatment of NF could reduce the LPS-induced inflammatory responses via deactivation of NF-κB. This study could suggest that NF could be a beneficial drug or agent to prevent inflammation.

  • Background: Korean ginseng (Panax ginseng) plays an anti-inflammatory role in a variety of inflammatory diseases such as gastritis, hepatitis, and colitis. However, inflammation-regulatory activity of the calyx of the P. ginseng berry has not been thoroughly evaluated. To understand whether the calyx portion of the P. ginseng berry is able to ameliorate inflammatory processes, an ethanolic extract of P. ginseng berry calyx (Pg-C-EE) was prepared, and lipopolysaccharide-activated macrophages and HEK293 cells transfected with inflammation-regulatory proteins were used to test the anti-inflammatory action of Pg-C-EE. Methods: The ginsenoside contents of Pg-C-EE were analyzed by HPLC. Suppressive activity of Pg-C-EE on NO production, inflammatory gene expression, transcriptional activation, and inflammation signaling events were examined using the Griess assay, reverse transcription-polymerization chain reaction, luciferase activity reporter gene assay, and immunoblotting analysis. Results: Pg-C-EE reduced NO production and diminished mRNA expression of inflammatory genes such as cyclooxygenase-2, inducible NO synthase, and tumor necrosis factor-${\alpha}$ in a dose-dependent manner. This extract suppressed luciferase activity induced only by nuclear factor-${\kappa}B$. Interestingly, immunoblotting analysis results demonstrated that Pg-C-EE reduced the activities of protein kinase B (AKT)1 and AKT2. Conclusion: These results suggest that Pg-C-EE may have nuclear-factor-${\kappa}B$-targeted anti-inflammatory properties through suppression of AKT. The calyx of the P. ginseng berry is an underused part of the ginseng plant, and development of calyx-derived extracts may be useful for treatment of inflammatory diseases.

  • Effect of brine mineral water(BMW) on contact hypersensitivity reaction(CHR) was estimated using trimellitic anhydride (TMA) induced CHR in the mouse. BMW exhibited potent inhibitory activity on TMA induced CHR. BMW treatment suppressed the ear swelling, and attenuated hyper-activated lymph nodes stimulated by TMA challenge, thereby reduced their weight. The immunological index was analyzed after BMW administration in CHR. The level of serum IgE was significantly down regulated after BMW treatment. Furthermore, BMW showed inhibitory property of cytokine production. BMW treatment suppressed not only Th2 type cytokine, IL-4 but also pro-inflammatory cytokines such as TNF-${\alpha}$ and IL-6. From the histological analysis, the inflammatory context appeared by atopic dermatitis lesion after challenging with TMA are diminished by BMW treatment. Our results suggest that BMW may attenuate the development of CHR, and can be available for functional ingredient.
