Abstract
AIMS:
Our previous study showed that the extract of Inula japonica Thunb. (I. japonica) has anti-inflammatory and anti-asthmatic activities. In an attempt to find anti-inflammatory compounds from I. japonica, we recently isolated 1,6α-dihydroxy-4αH-1,10-secoeudesma-5(10),11(13)-dien-12,8β-olide (SE), 6α-isobutyryloxy-1-hydroxy-4αH-1,10-secoeudesma-5(10),11(13)-dien-12,8β-olide (IBSE), and 6α-isovaleryloxy-1-hydroxy-4αH-1,10-secoeudesma-5(10),11(13)-dien-12,8β-olide (IVSE) from the extract of I. japonica, and investigated their inhibitory effects on nitric oxide (NO) production in lipopolysaccharide (LPS)-stimulated RAW264.7 cells.
MAIN METHODS:
The inhibitory effect of IVSE, SE and IBSE on NO production in LPS-induced RAW264.7 cells was examined using Griess reagent, and the effects of IVSE on the expressions of inducible nitric oxide synthase (iNOS) and its upstream signal proteins including IκB kinase (IKK)/inhibitor kappa B (IκB)-α/nuclear factor κB (NF-κB) and mitogen-activated protein kinases (MAPKs) were investigated by Western blot.
KEY FINDINGS:
Among the 3 compounds isolated, SE, IBSE, and IVSE inhibited NO production at 2.5 μM with 5.1%, 40.4%, and 52.8%, respectively. IVSE displayed the most potent inhibition of NO production. Mechanism analysis indicated that IVSE dramatically decreased the expression of iNOS, reduced the translocation of the NF-κB subunit p65 into the nucleus by interrupting the phosphorylation and degradation of IκB-α, and inhibited the activation of the upstream mediator IKK α/β. Furthermore, our results showed that IVSE inhibited the phosphorylation of MAPKs including extracellular regulated kinases (ERK1/2), c-Jun N-terminal kinases (JNK) and p38.
SIGNIFICANCE:
IVSE exhibited anti-inflammatory activity by inhibiting NO production, in which inactivation of NF-κB and MAPKs might be involved. Our results suggest that IVSE might become an anti-inflammatory drug candidate.

Flowers of Inula japonica Attenuate Inflammatory Responses.
Choi JH, Park YN, Li Y, Jin MH, Lee J, Lee Y, Son JK, Chang HW, Lee E.
Abstract
BACKGROUND:
The flowers of Inula japonica (Inulae Flos) have long been used in traditional medicine for the treatment of inflammatory diseases. In the present study, we investigated the anti-inflammatory properties of Inulae Flos Extract (IFE).
METHODS:
The anti-inflammatory effects of IFE against nitric oxide (NO), PGE(2), TNF-α, and IL-6 release, as well as NF-κB and MAP kinase activation were evaluated in RAW 264.7 cells.
RESULTS:
IFE inhibited the production of NO and the expression of inducible nitric oxide synthase (iNOS) in LPS-stimulated RAW264.7 cells. In addition, IFE reduced the release of pro-inflammatory cytokines, such as TNF-α and IL-6. Furthermore, IFE inhibited the NF-κB activation induced by LPS, which was associated with the abrogation of IκB-α degradation and subsequent decreases in nuclear p65 and p50 levels. Moreover, the phosphorylation of ERK, JNK, and p38 MAP kinases in LPS-stimulated RAW 264.7 cells was suppressed by IFE in a dose-dependent manner.
CONCLUSION:
These results suggest that the anti-inflammation activities of IFE might be attributed to the inhibition of NO, iNOS and cytokine expression through the down-regulation of NF-κB activation via suppression of IκBα and MAP kinase phosphorylation in macrophages.

Inula Japonica Thunb. Flower Ethanol Extract Improves Obesity and Exercise Endurance in Mice Fed A High-Fat Diet
So-Hyun Park, Da-Hye Lee, Min Jung Kim, Jiyun Ahn, Young-Jin Jang, Tae-Youl Ha, Chang Hwa Jung
Abstract
Inula japonica Thunb. (Asteraceae) is a flowering plant that grows mainly in Korea, Japan, and China and its flower extract has diverse biological effects such as anti-inflammatory and antioxidative activities. However, the effects on obesity and enhancement of endurance capacity have not been explored yet. This study aims to reveal the effects of I. japonica flower ethanol extract (IJE) on obesity and endurance capacity in high-fat diet (HFD) fed C57BL/6J mice and the mechanism. IJE inhibited lipid accumulation in 3T3-L1 adipocytes in vitro. Also, IJE-fed mice showed reduced body weight gain, hepatic lipid, and body fat mass, and increased muscle weight. IJE reduced lipid accumulation in the liver and adipose tissue by decreasing lipogenic and adipogenic gene expression. Additionally, consumption of low-dose IJE significantly enhanced endurance capacity via increasing AMP-activated protein kinase activity and mRNA levels of Myh7 and Myh2. Luteolin and 1β-hydroxyalantolactone (1β-HA), compounds of IJE, are involved in anti-adipogenesis in the 3T3-L cells and only luteolin increased the protein levels of MHC during C2C12 myoblast differentiation. Collectively, our results suggest that consumption of IJE not only helps to prevent obesity but also enhances endurance capacity reduced by HFD.

Hong Zhu, Sheng-An Tang, Nan Qin, Hong-Quan Duan, Mei-Hua Jin
Abstract
Chemical constituents of Inula japonica were isolated and purified by repeated column chromatographies, over silica gel, and Toyopearl HW-40, and preparative HPLC. On the basis of spectral data analysis, including NMR and MS data, the structures of the isolates were elucidated and their anti-inflammatory activities were assayed. Fifteen compounds were isolated from the ethyl acetate extract of I. japonica, and their structures were elucidated as dihydrosyringenin (1), (3S, 5R, 6S, 7E)-5,6-epoxy-3-hydroxy-7-megastigmen-9-one (2), (6R, 7E) -9-hydroxy-4,7-megastigmadien-3-one (3), arnidiol (4), taraxasterol acetate (5), 8,9,10-trihydroxythymol (6), taxifolin (7), luteolin (8), napetin (9), eupatin (10), spinacetin (11), quercetin (12), p-hydroxycinnamic acid (13), caffeic acid (14), and caffeoyl acetate (15). Compounds 1, 2, 7, 13 and 15 were isolated from the genus Inula for the first time, and compounds 3, 4, 9-11 and 14 were isolated from this plant for the first time. The anti-inflammatory activity result showed that compounds 3, 6-12 and 14 exhibited inhibition effect against leukotriene C4 (LTC4) synthesis and degranulation definitely in c-Kit Ligand (KL) induced mast cells, and compound 8 and 12 also had the suppression effect against lipopolysacharide(LPS) induced nitric oxide (NO) activity in RAW264.7 macrophages. It is firstly reported that compounds 7 and 9-11 possessed potent inhibition activities against LTC4 generation and degranulation in mast cells.

Isolation and identification of acaricidal compounds in Inula japonica (Asteraceae)
D D Duan, C Y Bu, J Cheng, Y N Wang, G L Shi
Abstract
We identified acaricidal compounds in Inula japonica Thunberg (Asteraceae) that were effective against carmine spider mite, Tetranychus cinnabarinus (Boisduval). Petroleum-ether extracts from I. japonica were toxic to T. cinnabarinus, with a 50% lethal concentration (LC50) value of 1.18 mg/ml. Silica gel column chromatography was used to separate the acaricidal components. Seventeen of 38 fraction groups had mite mortality rates >50%, nine fraction groups had rates >60%, and three fraction groups had rates >80% at 2 mg/ml. The major volatile compounds in the bioactive fraction groups were identified by gas chromatography-mass spectroscopy, and beta-sitosterol (1), stigmasterol (2), lupeol (3), and alpha-amyrin (4) were identified and determined to have acaricidal activity against T. cinnabarinus in vitro.

Abstract
Eight sesquiterpene lactones were isolated from the roots of Inula helenium and flowers of I. japonica. Among them, isoalantolactone (3) and santamarine (6) exhibited significant growth inhibitory activities against gynecologic cancer cell lines, while others weakly inhibited the growth of the cell lines (IC50 < or = 100 microM). In addition, 3 significantly inhibited the tumour growth of S180 tumour-bearing mice. Compounds 3 and 6 were not toxic to human embryonic lung fibroblast cells in vitro. These results demonstrated that the antitumour activities are closely related to the structures of the compounds, that is, an alpha-exomethylene-gamma-lactone ring is necessary for these activities.
