Sparassis crispa is a kind of edible fungus widely grows in the north temperate zone, which shows various medicinal properties. Due to the complexity of chemical constitutes of this species, few investigations have acquired a comprehensive configuration for the chemical profile of it. In this study, a strategy based on ultra-high performance liquid chromatography (UPLC) combined with Orbitrap mass spectrometer (MS) was established for rapidly characterizing various chemical components in S. crispa. Through the summarized MS/MS fragmentation patterns of reference compounds and systematic identification strategy, a total of 110 components attributed to six categories were identified for the first time. Moreover, allergic rhinitis (AR) is a worldwide inflammatory disease seriously affecting human health, and the development of drugs to treat AR has been a topic of interest. It has been reported that the extracts of S. crispa showed obvious inhibitory effects on degranulation of mast cell- and allergen-induced IgE and proinflammatory mediators, but the active components and specific mechanism were still not clear. Src family kinases (SFKs) participate in the initial stage of allergy occurrence, which are considered the targets of AR treatment. Herein, on the basis of that self-built chemical database, virtual screening was applied to predict the potential SFKs inhibitors in S. crispa, using known crystal structures of Hck, Lyn, Fyn, and Syk as receptors, followed by the anti-inflammatory activity evaluation for screened hits by intracellular calcium mobilization assay. As results, sparoside A was directly confirmed to have strong anti-inflammatory activity with an IC50 value of 5.06 ± 0.60 μM. This study provides a useful elucidation for the chemical composition of S. crispa, and demonstrated its potential inhibitory effects on AR, which could promote the research and development of effective agents from natural resources.

AbstractFisetin is a naturally occurring flavonoid that possesses several pharmacological benefits including anti-inflammatory activity. However, its precise anti-inflammatory mechanism is not clear. In the present study, we found that fisetin significantly inhibited the expression of proinflammatory mediators, such as nitric oxide (NO) and prostaglandin E2 (PGE2), and cytokines, such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. Additionally, fisetin attenuated LPS-induced mortality and abnormalities in zebrafish larvae and normalized the heart rate. Fisetin decreased the recruitment of macrophages and neutrophils to the LPS-microinjected inflammatory site in zebrafish larvae, concomitant with a significant downregulation of proinflammatory genes, such as inducible NO synthase (iNOS), cyclooxygenase-2a (COX-2a), IL-6, and TNF-α. Fisetin inhibited the nuclear localization of nuclear factor-kappa B (NF-κB), which reduced the expression of pro-inflammatory genes. Further, fisetin inactivated glycogen synthase kinase 3β (GSK-3β) via phosphorylation at Ser9, and inhibited the degradation of β-catenin, which consequently promoted the localization of β-catenin into the nucleus. The pharmacological inhibition of β-catenin with FH535 reversed the fisetin-induced anti-inflammatory activity and restored NF-κB activity, which indicated that fisetin-mediated activation of β-catenin results in the inhibition of LPS-induced NF-κB activity. In LPS-microinjected zebrafish larvae, FH535 promoted the migration of macrophages to the yolk sac and decreased resident neutrophil counts in the posterior blood island and induced high expression of iNOS and COX-2a, which was accompanied by the inhibition of fisetin-induced anti-inflammatory activity. Altogether, the current study confirmed that the dietary flavonoid, fisetin, inhibited LPS-induced inflammation and endotoxic shock through crosstalk between GSK-3β/β-catenin and the NF-κB signaling pathways.

Sanguisorbae Radix (SR) is the root of the Sanguisorba officinalis L., a plant native to Asian countries and used in traditional medicine. We isolated the active components of SR and investigated their anti-inflammatory potential. Quercetin (QC), (+)-catechin (CC), and gallic acid (GA) were isolated from acetone extracts of SR. To elucidate the molecular mechanism by which these compounds suppress inflammation, we analyzed the transcriptional up-regulation of inflammatory mediators, such as nuclear factor-kappa B (NF-κB) and its target genes, inducible NOS (iNOS), and cyclooxygenase (COX)-2, in lipopolysaccharide (LPS)-stimulated macrophage RAW264.7 cells. Notably, QC, CC, and GA were found to inhibit the production of nitric oxide, tumor necrosis factor-alpha, and prostaglandin in a dose-dependent manner. Western blot results indicate that the compounds decreased the expression of iNOS and COX-2 proteins. Furthermore, the compounds decreased phosphorylation of IKK, IκB, ERK, p-38, and JNK proteins in LPS-induced cells. The results support the notion that QC, CC, and GA can potently inhibit the inflammatory response, with QC showing the highest anti-inflammatory activity. In in vivo toxicity studies in zebrafish (Danio rerio), QC showed no toxicity up to 25 μg/mL. Therefore, QC has non-toxic potential as a skin anti-inflammatory biomaterial.

This study aimed at investigating the anti-inflammatory potential of essential oil from rhizome and leaf of Alpinia calcarata Rosc. (ACEO) with the focus of its topical anti-inflammatory activity along with its dominant compounds 1,8-cineole and α-terpineol using mouse ear edema model. ACEOs were analyzed by GC-MS. The anti-inflammatory activity was determined by studying the inhibition of overproduction of proinflammatory mediators—nitric oxide, reactive oxygen species, prostaglandins, cyclooxygenases, and cytokines induced by lipopolysaccharides in murine macrophages. Topical anti-inflammatory and antinociceptive activity was studied by 12-O-tetradecanoylphorbol-13-acetate (TPA) induced skin inflammation and formalin-induced pain model in mice, respectively. Rhizome oil has 1,8-cineole (31.08%), α-terpineol (10.31%), and fenchyl acetate (10.73%) as major compounds whereas the ACEO from leaves has 1,8-cineole (38.45%), a-terpineol (11.62%), and camphor (10%). ACEOs reduced the production of inflammatory mediators in vitro in a concentration-dependent manner. Further, ACEO and its major compounds reduced ear thickness, weight, myeloperoxidase, and cytokines significantly (p<0.01) in mouse ear. Dose-dependent reduction in flinching and licking in both the phases of pain sensation concludes the topical analgesic effect. Our findings suggest the potency of topical use of ACEOs for inflammatory disease conditions.

Background: "Opuntia ficus-indica" (prickly pear) is the cactus member of the Cactaceae family as an important nutrient and food source. Objective: The purpose of this study was to characterize the phytochemical composition of hydroalcoholic extract of prickly pear seeds that cause therapeutic effects. Method: Phytochemical screening based on simple tests and determination of secondary metabolites were performed by High-Performance Liquid with Diode-Array Detection (HPLC-DAD) analysis. For the pharmacological studies, the anti-inflammatory activity in rats was evaluated by carrageenaninduced inflammation, the description of the sedative activity was carried to the following behavioural tests, and the analgesic effect of the extract was assessed by the resistance induced by acetic acid, and the tail immersion test in mice. Results: The test drug at 500 mg/kg dose showed a significant increase in mean latency in the TAIL FLICK test, and a decrease in the average number of twisting movements in the KOSTER test, thus, a significant anti-inflammatory activity in the pattern of paw edema induced by carrageenan, and an important sedative effect on the central nervous system. Conclusion: These data suggest that the seeds of the cactus "Opuntia ficus-indica" could be a potential source of natural compound and reveal that the hydroethanolic extract of this species is a promising source, as well as a therapeutic agent for the research of new natural active ingredients.

In this study, triterpenoid compounds from Poriae Cutis were separated by high-speed countercurrent chromatography (HSCCC) and identified using ultra-high performance liquid chromatography quadrupole time-of-flight tandem mass spectrometry (UHPLC-QTOF-MS/MS) and nuclear magnetic resonance (NMR). The in vitro anti-inflammatory activities of the purified triterpenoids on RAW 264.7 cells were also investigated. Triterpenoids, poricoic acid B, poricoic acid A, dehydrotrametenolic acid, and dehydroeburicoic acid were obtained; their levels of purity were 90%, 92%, 93%, and 96%, respectively. The results indicated that poricoic acid B had higher anti-inflammatory activity than those of poricoic acid A by inhibiting the generation of NO in lipopolysaccharide (LPS)-induced RAW 264.7 cells. However, dehydrotrametenolic acid and dehydroeburicoic acid had no anti-inflammatory activity. In addition, the production of cytokines (TNF-α, IL-1β, and IL-6) in cells treated with poricoic acid B decreased in a dose-dependent manner in the concentration range from 10 to 40 μg/mL. The results provide evidence for the use of Poriae Cutis as a natural anti-inflammatory agent in medicines and functional foods.

Elevated levels of circulating inflammatory markers predict an unfavorable cardiovascular outcome in acute coronary syndrome patients. CSL112 is human apolipoprotein A-I (apoA-I), reconstituted with phosphatidylcholine to form HDL particles suitable for infusion. Addition of CSL112 to stimulated human whole blood ex vivo strongly reduces pro-inflammatory cytokine production. Infusion of CSL112 into human subjects or addition to human plasma ex vivo causes remodeling of endogenous HDL. Similar remodeling occurs upon incubation of CSL112 with purified HDL3 and results in accumulation of three HDL species: enlarged HDL (HDL2), a smaller, dense species (HDL3c), and lipid-poor apoA-I (pre-β1 HDL). Study aim was to determine the anti-inflammatory activity of remodeled HDL species. CSL112 was incubated with HDL3 and the products of particle remodeling were purified by ultracentrifugation. The inhibitory effects on pro-inflammatory cytokine production were examined using human peripheral blood mononuclear cells (PBMC) stimulated with phytohemagglutinin-M (PHA-M) in vitro. Lipid-poor apoA-I, HDL3c as well as parent CSL112 exerted powerful inhibitory effects on secretion of pro-inflammatory mediators (> 89.2% + 4.0% inhibition of TNF-α, IL-1β, IL-6 and Mip-1β); HDL3 and HDL2 were much less effective (< 54.1% + 3.9% inhibition). The extent of inhibition correlated positively with induction of the transcription repressor ATF3, a negative regulator of pro-inflammatory cytokine production, with lipid-poor apoA-I and HDL3c inducing higher protein levels of ATF3 in PHA-stimulated PBMC compared to control medium, HDL3 or HDL2. Anti-inflammatory activity of the remodeled species also correlated with their ability to support cellular cholesterol efflux via the ABCA1 transporter: lipid-poor apoA-I and HDL3c were potent acceptors of cholesterol; HDL2 was inactive. The ability to generate HDL species with high cholesterol efflux and anti-inflammatory activity makes CSL112 a promising candidate for removing cholesterol and reducing inflammation in atherosclerotic plaque, thus reducing the high risk of early recurrent atherothrombotic events following acute MI (AMI). A Phase IIb trial (AEGIS-I; NCT02108262) of CSL112 in AMI patients is ongoing.

Five extracts (n-hexane, chloroform, ethyl acetate, n-butanol and water) of Scutellaria rivularis Benth. were evaluated for their anti-inflammatory activity against carrageenan-induced paw edema in rats and compared with indomethacin. The result indicated that chloroform extract proved to be the most effective in all of the extracts. Consequently, three major components (baicalin, baicalein and wogonin) of the chloroform extract were further tested for their anti-inflammatory activity using the same model. It was found that baicalin exhibits the greatest inhibition activity against carrageenan-induced rat paw edema.
