Abstract
Polyphenols are inhibitors for lipase, but the binding selectivity and mechanism of polyphenol isomers and how they interact with lipase are not clear. Here, chlorogenic acid (CGA) isomers, neochlorogenic acid (NCGA) and cryptochlorogenic acid (CCGA) were used to explore the binding selectivity and mechanism of lipase. An inhibition assay indicated that both CGA isomers had dose-dependent inhibitory effects on lipase; however, the inhibitory effect of NCGA was better (IC50: 0.647 mg/mL) than that of CCGA (IC50: 0.677 mg/mL). NCGA and CCGA formed complexes with lipase at a molar ratio of 1:1, and the electrostatic interaction force plays a major role in the lipase-CCGA system. Molecular dynamics studies demonstrated that NCGA had a greater impact on the structure of lipase. The multi-spectroscopic and modeling results explained the effects of micro-structural changes on the binding site, the interaction force and the inhibition rate of the isomers when they combined with lipase.

Abstract
Hydrocotyle umbellata L. (Family Araliaceae) populary known as Acaricoba, is indicated in folk medicine for treatment of several inflammatory disorders. The goal of the present study is to evaluate the anti-inflammatory activity of the defatted ethanolic extract (DEE) of the aerial parts using carrageenan-induced rat paw oedema method. The levels of the pro-inflammatory cytokine interleukin-6 (IL-6) and the inflammatory mediator prostaglandin E2 (PGE2) were assessed using ELISA. The DEE at dose level 100 mg/kg showed significant decrease in oedema volume after 2 and 3 h, equivalent to 70.75% and 95.92% of the activity of the standard anti-inflammatory indomethacin, respectively. DEE significantly decreased the concentrations of the excessively produced IL-6 and PGE2 (24 ± 2.1 and 2374 ± 87 pg/mL compared to 16 ± 2 and 2419 ± 95 pg/mL induced by indomethacin). Chemical investigation was carried out to isolate and identify the bioactive compounds that might be responsible for this activity. The total phenolic (79.28 ± 0.1 mg) and total flavonoid (57.99 ± 0.1 mg) contents of the DEE were quantified spectrophotometricaly and expressed as gallic acid and rutin equivalents/g dry weight, respectively. The DEE was subjected to further fractionation using solvents of increasing polarities. Purification of the ethyl acetate fraction using different chromatographic techniques led to the isolation of five compounds, which were identified through 1D and 2D and UV/Vis spectral data. The five compounds were: quercetin, avicularin, quercitrin, hyperoside, and neochlorogenic acid. Several biological studies confirmed the important role of caffeoyl quinic acid and quercetin derivatives as anti-inflammatory bioactive compounds.

Abstract
Acute and chronic inflammatory diseases are associated with excessive inflammation due to the accumulation of pro-inflammatory mediators and cytokines produced by macrophages. In the present study, we investigated the anti-inflammatory properties of neochlorogenic acid (nCGA) from Lonicera japonica on lipopolysaccharide (LPS)-activated inflammation in macrophages and participation of the AMPK/Nrf2 pathway. nCGA pretreatment significantly reduced the production of nitric oxide, prostaglandin E2, TNF-α, reactive oxygen species, IL-1β, and IL-6 by LPS-activated macrophages. Moreover, both transcript and protein levels of inducible nitric oxide synthase and cyclooxygenase-2 were reduced by nCGA in LPS-activated macrophages. nCGA inhibited NF-κB activation by attenuating IKKα/β and IκBα phosphorylation in LPS-stimulated macrophages. Moreover, nCGA attenuated LPS-elevated JAK-1, STAT-1, and MAPK phosphorylation. We further evaluated the possible role of nCGA in the induction of AMPK/Nrf2 signal pathways required for the protein expression of HO-1 and NQO-1. nCGA induced AMPK activation via phosphorylation of LKB1 and CaMKII and by the inhibitory phosphorylation of GSK3β. It stimulated the overexpression of Nrf2/ARE-regulated downstream proteins, such as NQO-1 and HO-1. Furthermore, the anti-inflammatory effects of nCGA were attenuated in macrophages subjected to siRNAs specific for HO-1, NQO-1, Nrf2, and AMPK. Accordingly, these results indicate that nCGA, as an AMPK/Nrf2 signal activator, prevents excessive macrophage-mediated responses associated with acute and chronic inflammatory disorders.

Abstract
Dried plum (DP), a rich source of polyphenols has been shown to have bone-preserving properties in both animal models of osteoporosis and postmenopausal women. We evaluated if DP alleviated the destruction of joints in transgenic mice (TG) that overexpress human tumor necrosis factor (TNF), a genetic model of rheumatoid arthritis (RA). A four-week treatment of 20% DP diet in TG slowed the onset of arthritis and reduced bone erosions in the joints compared to TG on a regular diet. This was associated with fewer tartrate-resistant acid phosphatase (TRAP) positive cells, suggesting decreased osteoclastogenesis. A DP diet also produced significant protection of articular cartilage and reduction of synovitis. Cultures of human synovial fibroblast in the presence of TNF showed a significant increase in inflammatory interleukin (IL)-1β, chemokines (monocyte chemoattractant protein-1: MCP1 & macrophage inflammatory protein-1 alpha: MIP1α), cartilage matrix metalloproteinases (MMP1&3), and an osteoclastogenic cytokine (receptor activator of nuclear factor-κB ligand: RANKL) compared to controls. Addition of neochlorogenic acid (NC), a major polyphenol in DP to these cultures resulted in down-regulation of these genes. In the cultures of mouse bone marrow macrophage, NC also repressed TNF-induced formation of osteoclasts and mRNA levels of cathepsin K and MMP9 through inhibition of nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1) expression and nuclear factor kappa B (NF-κB) activation. Our data suggested that dietary supplementation with DP inhibited TNF singling; leading to decreased erosions of bone and articular cartilage as well as synovitis.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Chlorogenic acid (CA) is one of the major ingredients in Honeysuckle which exhibits anticancer, antibacterial, antiviral, hypoglycemic and anti-HIV activities. However, with the frequent emergence of anaphylactoid reactions of traditional Chinese medicine (TCM) injections which contains Honeysuckle in recent years, many researchers found that CA exhibited allergenicity. AIM OF THE STUDY To explore the changes of content of CA, neochlorogenic acid (NCA) and cryptochlorogenic acid (CCA) during the preparation of Honeysuckle and evaluate the anaphylactoid of these three ingredients. MATERIALS AND METHODS Two extracts of Honeysuckle were prepared by different methods and the content of CA, NCA and CCA were determined by high performance liquid chromatography (HPLC) analysis. Guinea pig and mast cells RBL-2H3 were utilized as the animal and cell model to investigate the anaphylactoid of these three ingredients. RESULTS The content of CA decreased while CCA and NCA increased during the preparation of Honeysuckle. In vitro and in vivo studies showed that CA and CCA could significantly increase the plasma serotonin and β-hexosaminidase levels in guinea pigs and induce the degranulation of RBL-2H3 cell, while NCA did not show such properties. In addition, CAA had a stronger effect than CA. CONCLUSION We believed that both CA and CCA could cause anaphylactoid reaction while NCA could not. Moreover, the anaphylactoid of CCA is higher than CA. Our result demonstrated that CA is not the only cause of anaphylactoid reactions of TCM injections which contains Honeysuckle.
