  • Asiaticoside has been tested for the ability as an anti-inflammatory drug using lipopolysaccharide (LPS)-stimulated macrophage cell line (RAW 264.7 cell). LPS treatment induced dramatically inducible nitric oxide synthase (iNOS) in RAW cells. However, asiaticoside inhibited LPS-stimulated iNOS induction in a concentration-dependent manner. Especially, higher concentrations (>50 $\mu\textrm{M}$) of asiaticoside completely blocked iNOS induction. In addition, LPS-stimulated expression of inducible cyclooxygenase (COX-2) and interleukin-1 $\alpha$ (IL-1 $\alpha$) was inhibited by asiaticoside treatment. Asiaticoside up to 50 $\mu\textrm{M}$ still required to inhibit COX-2 and IL-1 $\alpha$ induced by LPS. Consistent with these findings, treatment with asiaticoside suppressed do novo synthesis and cellular accumulation of prostaglandin $E_2$ to a lesser extent, suggesting that asiaticoside blocked the induction as well as the activity of COX-2 These results suggest the possibility that asiaticoside may be effective therapeutic agents for septic shock and other inflammatory diseases.

  • Flavonoids, a group of low molecular weight phenylbenzopyrones, have various pharmacological properties including antioxidant activity, anticancer, and immunomodulatory effects. In the present study, lipopolysaccharide (LPS) and phorbol 12-myristate 13-acetate/phytohemagglutinin (PMA/PHA) were used as stimulants for RAW 264.7 macrophages and human peripheral blood mononuclear cell (hPBMC), and tumor necrosis factor (TNF)-${\alpha}$ and interleukin (IL)-2 productions were measured. In addition, flavonoids were examined for their effects on LPS-induced NO production in RAW 264.7 macrophages. The results showed that all compounds were not strongly cytotoxic at the tested concentrations on hPBMC and RAW 264.7 macrophages. On immunomodulatory properties, catechin, epigallocatechin (EGC), naringenin, and fisetin repressed NO production and TNF-${\alpha}$ secretion. Furthermore, catechin, epigallocatechin gallate (EGCG), epicatechin (EC), luteolin, chrysin, quercetin, and galangin increased IL-2 secretion while EGC, apigenin, and fisetin inhibited the secretion. These results indicated that flavonoids have the capacity to modulate the immune response and have a potential anti-inflammatory activity. There was no obvious structure-activity relationship regard to the chemical composition of the flavonoids and their cell biological effects.

  • The present study was performed to examine the possible anti-inflammatory effects of a herbal drug ASCH in RAW264.7 cell line. Inflammation was induced by LPS toxin treatment to RAW264.7 macrophage cell line. Increases in cytokine production such as IL-1β, IL-6. and IL-18, COX-2, NOS-Ⅱ (iNOS), and TNF-alpha were observed at mRNA level in the LPS-treated RAW264.7 cells. Measurement of IL-6, nitric oxide and the reactive oxygen species (ROS) showed increased production of these inflammation mediators. Treatment of ASCH effectively decreased IL-1β protein in a dose-dependent manner, and IL-6 and IL-18 were reduced at 100㎍/㎖ of ASCH concentration. NO production was also decreased by ASCH treatment. A slight inhibition for TNF-alpha in terms of protein, but not mRNA level was obtained by 100㎍/㎖ of ASCH treatment. ASCH treatment to normal RAW264.7 cells did not produce any cytotoxicity, indicting that the action of ASCH was selective to inflammatory cells. Thus, the present data suggest that ASCH may act as an important regulator to alleviate the inflammatory symptoms.

  • Objectives : Sam-Myo-Whan(SMW) has been known traditional prescription with anti- anthritis activities. We investigated inhibitory effects of SMW on lipopolysaccharide (LPS)-induced nitric oxide(NO), $TNF-{\alpha}$ and inducible nitric oxide synthase(iNOS) production from RAW264.7 cells and BV-2 Microglia cells. Methods : SMW, which had been extracted with 70% MeOH, concentrated and freeze-dried was used for this experiment. After BV2 mouse brain macrophages and RAW264.7 mouse peritoneal macrophages were pretreated with increasing concentrations of SMW extract for 30min, and then activated with LPS. To investigate cytotoxicity of SMW extract, cell viability was measured by MTT assay. NO production was measured in each culture supernatant by Griess reaction. mRNA expression of iNOS in two type cells was investigated by RT-PCR. $TNF-{\alpha}$ production was measured in each culture supernatant by ELISA. Results : SMW extract significantly inhibited LPS-induced NO and $TNF-{\alpha}$ production in BV2 cells and RAW264.7 cells dose-dependently. SMW extract also greatly suppressed mRNA expression of iNOS in both type cells activated with LPS. Conclusion : These data suggests that SMW extract may have an anti-inflammatory effect through the inhibition of iNOS expression.

  • This study investigated the anti-inflammatory effects of processed (Beopje) curly dock (Rumex crispus L.) in LPS (lipopolysaccharide)-stimulated murine RAW 264.7 cells. The experimental group was classified into five groups : LPS no treatment, CD (curly dock), CD-B (CD processed through Beopje), LPS, LPS+CD-B (LPS+CD processed through Beopje) and LPS+CD (LPS+CD). Treatment of the Raw 264.7 cell lines using LPS led to a significant increase in NO production, pro-inflammatory cytokines ($TNF-{\alpha}$, IL-6 and $IL-1{\beta}$), and inflammation related genes (COX-2 and iNOS). Investigation of the inhibitory effects of CD and processed CD on NO production and expression of iNOS and COX-2 was done in LPS-induced RAW 264.7 cells. There was significant inhibition of NO production by LPS+CD and LPS+CD-B in a dose-dependent manner (p<0.05). Particularly, LPS+CD-B exhibited reduced mRNA expression of iNOS and COX-2 and NO production as compared to LPS+CD in Raw 264.7 cell lines (p<0.05). These results may explain some known biological activities of curly dock including the anti-inflammatory effects. CD-B in particular exhibited the highest anti-inflammatory effects of inhibiting production of NO, through the regulation of inflammatory related genes and pro-inflammatory cytokines. These results of Beopje processing might help decrease the anti-biological effects and increase several active substances of curly dock.
