Isoacteoside, a dihydroxypheynylethyl glycoside, is a major bioactive component of Abeliophyllum distichum (White Forsythia) which is a deciduous shrub native to the south and central areas of Korea. The present study is designed to evaluate the anti-inflammatory activities and underlying mechanisms of isoacteoside in human mast cell line, HMC-1 cells. We isolated isoacteoside from A. distichum. The anti-inflammatory effect of isoacteoside was investigated in HMC-1 cells by studying the following markers: phorbol 12-myristate 13-acetate and calcium ionophore A23187 (PMACI)-induced interleukin (IL)-1β, IL-6, IL-8, and tumor necrosis factor alpha (TNF-α) secretion and mRNA expression by ELISA and RT-PCR, respectively. In addition, mechanism related to anti-inflammatory was investigated by Western blotting. Isoacteoside significantly suppressed the production and mRNA expression of proinflammatory cytokines including IL-1β, IL-6, IL-8 and TNF-α in PMACI-stimulated HMC-1 cells without cytotoxicity. It was found that anti-inflammatory effects of isoacteoside are mediated by action on caspase-1, mitogen-activated protein kinases (c-Jun N-terminal kinase, p38, extracellular signal-regulated protein kinase) and nuclear factor-kappa B pathways. Taken together, the present findings provide new insights that isoacteoside may be a promising anti-inflammatory agent for inflammatory disorders.

BACKGROUND AND PURPOSE:
Isoacteoside (is a phenylethanoid isolated from Monochasma savatieri Franch. ex Maxim., which is an anti-inflammatory herb widely used in traditional Chinese medicine. However, the exact mechanism of the anti-inflammatory activity of isoacteoside is not completely understood. In this study, its anti-inflammatory mechanism was elucidated in mouse macrophages.
The expression of the NF-κB pathway, MAPK pathway, iNOS, TNF-α, IL-6 and IL-1β was evaluated using Western blotting, quantitative real-time PCR or ELISA. TLR4 dimerization was determined by transfecting HEK293T cells with TLR4 plasmids. The in vivo anti-inflammatory effect of isoacteoside was determined using mouse models of xylene-induced ear oedema, LPS-induced endotoxic shock and LPS-induced endotoxaemia-associated acute kidney injury (AKI).
Isoacteoside suppressed COX-2, iNOS, TNF-α, IL-6 and IL-1β expression. Furthermore, isoacteoside attenuated the LPS-induced transcriptional activity of NF-κB by decreasing the levels of phosphorylated IκB-α and IKK and NF-κB/p65 nuclear translocation. In addition, isoacteoside inhibited LPS-induced transcriptional activity of AP-1 by reducing the levels of phosphorylated JNK1/2 and p38MAPK. Isoacteoside blocked LPS-induced TLR4 dimerization, resulting in a reduction in the recruitment of MyD88 and TIR-domain-containing adapter-inducing interferon-β (TRIF) and the phosphorylation of TGF-β-activated kinase-1 (TAK1). Pretreatment of mice with isoacteoside effectively inhibited xylene-induced ear oedema and LPS-induced endotoxic death and protected against LPS-induced AKI.
CONCLUSIONS AND IMPLICATIONS:
Isoacteoside blocked TLR4 dimerization, which activates the MyD88-TAK1-NF-κB/MAPK signalling cascades and TRIF pathway. Our data indicate that isoacteoside is a potential lead compound for the treatment of inflammatory diseases.

Acteoside and isoacteoside, two phenylethanoid glycosides, coexist in some plants. This study investigates the memory-improving and cytoprotective effects of acteoside and isoacteoside in amyloid β peptide 1-42 (Aβ 1-42)-infused rats and Aβ 1-42-treated SH-SY5Y cells. It further elucidates the role of amyloid cascade and central neuronal function in these effects. Acteoside and isoacteoside ameliorated cognitive deficits, decreased amyloid deposition, and reversed central cholinergic dysfunction that were caused by Aβ 1-42 in rats. Acteoside and isoacteoside further decreased extracellular Aβ 1-40 production and restored the cell viability that was decreased by Aβ 1-42 in SH-SY5Y cells. Acteoside and isoacteoside also promoted Aβ 1-40 degradation and inhibited Aβ 1-42 oligomerization in vitro. However, the memory-improving and cytoprotective effects of isoacteoside exceeded those of acteoside. Isoacteoside promoted exploratory behavior and restored cortical and hippocampal dopamine levels, but acteoside did not. We suggest that acteoside and isoacteoside ameliorated the cognitive dysfunction that was caused by Aβ 1-42 by blocking amyloid deposition via preventing amyloid oligomerization, and reversing central neuronal function via counteracting amyloid cytotoxicity.
