Lonicera japonica is widely distributed in Southeast Asia and has been traditionally used as an anti - inflammatory, diuretic, abscessic, antipyretic, and antidotic agent. Lonicera japonica was investigated for its anti-inflammatory and analgesic effects using several in vivo models. SKLJI was purified for i.v. injection from Lonicera japonica as a potent anti-inflammatory and analgesic fraction, after activity-guided fractionation study. (omitted)

This study was conducted to examine the bleaching of an anti-inflammatory agent containing Undaria pinnatifida extract (AIAU). Brown-colored AIAU was irradiated with $^{60}CO$ gamma rays at doses ranging from 10-200 kGy. Discoloring of the anti-inflammatory agent was achieved by gamma irradiation, with significantly removal by 50 kGy irradiation. The main active compound of the agent consisted of 4% U. pinnatifida extract, which inhibited inflammatory symptoms in mouse ear edema by 93%. There was no change in effects against edema, erythema, blood flow and radical scavenging activity by irradiation.

Many diselenide compounds are used as antioxidants, enzyme inhibitors and cytokine induc-ers. Three new diselenide compounds, bis-(2-hydroxyphenyl) diselenide, bis-(3-hydroxyphe-nyl) diselenide and bis-(4-hydroxyphenyl) diselenide were designed and synthesized as anti-inflammatory agent. All of them were found to have strong in vitro activity in anti-inflammatory assays.

Tertomotide는 항암제로 개발된 펩타이드 백신이다. 그러나 동물실험과 임상시험에서 염증성 증상이 완화되는 현상이 발견된바 있다. 이에 tertomotide가 항염물질로 작용하는지 확인하기 위하여 직접적인 항염활성과 그 작용기전을 조사하였다. 이를 위해 LPS 또는 PMA에 의해 활성화된 monocyte에 tertomotide를 처리한 후 염증성 cytokine 생산과 관련된 신호전달과정을 관찰하였다. Monocyte에서 tertomotide는 TNF-α, IL-1β, IL-8 등 염증성 싸이토카인의 생산을 감소시켰고 NF-κB 신호를 감쇄시켰으며 또한 TNF-α에 의한 ERK1/2와 P38 MAPK의 활성화를 저해하였다. 이 결과는 tertomotide 처치에 따른 염증성 질환 완화가 NF-κB/STAT3의 신호의 감쇄와 항염활성에 의한 것이라고 설명할 수 있고 이를 활용하여 신규 항염 약물의 도출이 가능할 것으로 판단된다. 이는 면역학적 활성을 목표로 계산화학적으로 설계된 물질의 생물학적 성질을 활용하여 새로운 약물을 도출하는 융합연구의 예시가 될 것이다.

Objectives : The aim of this study is to investigate anti-inflammatory activity using various extracts of rice straw (DaoCao) extract (RS).Methods : To investigate the anti-inflammatory effect of RS, we examined the effect of RS on cytokines production on THP-1 cell. Cells were cultured in incubator (37℃, CO₂5%, 0.5% FBS-RPMI, 1X10⁶cells/ml). One hour after,Dermatophagoides pteronissinus(Dp., 10 ug/ml) was treated into cell and at 6 hour after, each different concentrations(0.1, 1 and 10 ug/ml) of RS were treated. The cells were incubated for 16 hours and harvest the supernatant. The levels of IL-4, IL-5, IL-6, IL-8, MCP-1 and TNF-αwere determined using a commercially available ELISA kit.Results : We investigated whether RS has the inhibition of inflammatory response in Jurkat cells and THP-1 cells. RS suppressed secretion of IL-4, IL-5, and TNF-αinduced by house dust mites in Jurkat cells. It showed significant effects for all concentrations. RS suppressed the increased expression of IL-6, IL-8 and MCP-1 after treatment with mite in THP-1 cells. These results suggest that RS may be used as a valuable agent for treating allergic diseases such as atopy due to its anti-inflammatory property.Conclusions : RS showed significant biological activities with anti-inflammatory in the human T cells. These results suggest that RS may be used as a valuable agent for treating allergic diseases such as atopy due to its anti-inflammatory property. In terms of Korean traditional medicine, we expect the results to contribute to building of EBM (Evidence-Based Medicine).

Raphanus sativus L. has been reported to have anti-inflammatory and anti-tumor activity. However, the anti-inflammatory effect and mechanism of action of the Raphanus sativus L. seeds (RSS) with or without oil are still unknown. This study was undertaken to investigate the in-vitro anti-inflammatory effect with or without oil in the RSS on RAW 264.7 cells stimulated by lipopolysaccharide (LPS). Results showed the suppressed LPS-induced secretion of pro-inflammatory mediators such as nitric oxide (NO), inflammatory cytokine (IL-6, TNF-α). Additionally, a decrease in protein expression of iNOS was observed, but nuclear translocation of NF-κB p65 was not inhibited. To elucidate the underlying mechanism of the anti-inflammatory effect of RSS, the involvement of mitogen-activated protein kinase (MAPK) signaling pathways was examined. We also found that RSS blocked LPS-induced phosphorylation of c-Jun N-terminal kinase/stress-activated protein kinase (JNK) signaling but did not affect the phosphorylation of p38 MAPK and extracellular signal-regulated kinase (ERK) 1/2. These results suggest that RSS may have potential as an anti-inflammatory agent through the inhibition of LPS-induced inflammatory cytokine production via regulation of the JNK pathway.

The anti-inflammatory activity of acetylsalicylic acid maltol ester (aspalatone), a potential anti-thombotic agent, was studied using the several experimental animal models of inflammation. By oral administration, aspalatone was found to possess the weak anti-inflammatory activity in models of an acute inflammation, in which aspalatone showed approximately one-third to one-fourth of the anti-inflammatory activity of aspirin. Aspalatone (200 mg/kg/day) and aspirin (50 mg/kg/day), however, did not show the inhibitory activity against granuloma fomation and adjuvant-induced arthritis.

4,4'-diaminodiphenyl sulfone (dapsone) is a sulfone drug that has antibacterial effects on a variety of bacteria, especially Mycobacterium leprae; thus, it has been used to treat leprosy. Previous studies demonstrated that dapsone inhibits integrin-mediated adherence of neutrophils and production of prostaglandin $E_2$ by polymorphonuclear leukocytes. Hence, dapsone may act in immune cells and regulate cell-mediated inflammation processes. However, its anti-inflammatory effects remain unclear. The present study demonstrated that dapsone modulates the production of inflammation-related cytokines in immune cells. We employed the spleen cells of mice, which are major immune cells, and lipopolysaccharide (LPS) as a causative agent of inflammation for experiments. Dapsone induced a proportional change in splenocyte subsets and the apoptosis of spleen cells. Interestingly, dapsone decreased the production of tumor necrosis factor-alpha and interleukin (IL)-10, but not IL-6, in LPS-treated spleen cells. In other assays, we measured the dapsone-induced production of nitric oxide (NO) and the expression of activation markers of spleen cells. Dapsone decreased NO production in LPS-treated spleen cells. Taken together, our results demonstrate that dapsone has anti-inflammatory effects in immune cells and provide new insight into the potential uses of this agent.

Inflammation plays an important role in immune system's response to tissue injury and biological stimuli. However, excessive inflammation can cause tissue damage. Therefore, the development of naturally derived anti-inflammatory agents have received broad attention. In this study, we investigated the anti-inflammatory mechanism of Rubi Fructus (RF) extract on the mast cell-mediated inflammatory response. To determine the regulatory mechanism of RF in inflammatory reaction, we evaluated the effects of RF on secretion of interleukin (IL)-8, IL-6 and tumor necrosis factor (TNF)-α and activation of nuclear factor-κB (NF-κB) and caspase-1 in activated human mast cells-1 (HMC-1). The results showed that RF attenuated IL-8, IL-6 and TNF-α secretion in a concentration-dependent manner. Moreover, RF significantly attenuated caspase-1and NF-κB activation in activated HMC-1. Conclusively, the present results provide evidence that RF may be a promising agent for anti-inflammatory therapy.
