Four new sesquiterpenoids (1–4) and six known sesquiterpenoids (5–10), were isolated from the EtOAc phase of the ethanolic extract of Ainsliaea yunnanensis. Their structures were established by spectroscopic methods, including 1-D, 2-D NMR and HPLC-MS. All compounds were tested for their anti-inflammatory effect by the inhibition of the activity of NLRP3 inflammasome by blocking the self-slicing of pro-caspase-1, which is induced by nigericin, then the secretion of mature IL-1β, mediated by caspase-1, was suppressed. Unfortunately none of the compounds showed an anti-inflammatory effect.

Inflammatory Effect

Persistent inflammation disrupts functional recovery after spinal cord injury (SCI). Peroxisome proliferator-activated receptor gamma (PPAR-γ) activation promotes functional recovery in SCI rats by inhibiting inflammatory cascades and increasing neuronal survival. We sought to clarify the relationship between PPAR-γ activation and NACHT, LRR and PYD domain-containing protein 3 (NLRP3) inflammasome suppression, and the role of NF-κB in activating the NLRP3 inflammasome in neurons. In SCI rats, we found that rosiglitazone (PPAR-γ agonist) inhibited the expression of caspase-1. In in vitro neurons, G3335 (PPAR-γ antagonist) reversed the rosiglitazone-induced inhibition of caspase-1, interleukin 1 (IL-1β), and interleukin 6 (IL-6). Rosiglitazone inhibited the expression of NLRP3, caspase-1, IL-1β, and IL-6. However, the activator of NLRP3 could counteract this inhibition induced by PPAR-γ activation. NF-κB did not participate in the process of rosiglitazone-induced inhibition of NLRP3. Consistent with our in vitro results, we verified that locomotor recovery of SCI rats in vivo was regulated via PPAR-γ, NLRP3, and NF-κB. These results suggest that PPAR-γ activation exerts an anti-inflammatory effect by suppressing the NLRP3 inflammasome—but not NF-κB—in neurons and that PPAR-γ activation is a promising therapeutic target for SCI.

Background: Curcuma longa or turmeric is a popular Ayurvedic herb, traditionally used for various inflammatory conditions including rheumatoid arthritis and spondylitis. Turmeric which containing phytochemical ingredient curcumin is used in India for centuries as a topical anti inflammatory agent. Many of the currently used anti inflammatory agents like NSAID’s and glucocorticoids have many undesirable adverse effects, especially when they are used for long period. In the present study, Curcuma longa, a plant belonging to the Zingiberaceae family was chosen for investigating its anti-inflammatory effects.Methods: The rhizomes of Curcuma longa were collected locally. The extract was prepared by soxlet extraction with 50% ethanol. Albino rats of Wistar strain (170-250grams) obtained from the animal house of medical college Thiruvananthapuram were used. Aspirin was purchased from sigma Labs, Mumbai. Anti-inflammatory effect of the extract was done in rats by the method of Carrageenin induced paw oedema.Results: The ethanolic extract of Curcuma longa inhibited the development of oedema at the end of 3 hours. The anti-inflammatory activity exhibited by the extract was dose dependent and statistically significant at dose levels of 1000-mg/kg and comparable to that of standard drug used Aspirin.Conclusions: The present study with extract of Curcuma longa revealed that it has significant anti-inflammatory activity.

Abstract Background Some research has indicated that selenium (Se) plays a significant role during mastitis. However the intracellular anti-inflammatory effect of Se is not fully clear. Due to the ability of Staphylococcus aureus ( S. aureus ) to internalize into host cell, in this study we explored whether Se could regulate inflammation induced by S. aureus through reactive oxygen species (ROS)-mediated NLRP3 inflammasome in bMECs. Result bMECs were treated with 8 μmol/L Na 2 SeO 3 for 12 h before infected with S. aureus for 2 h. Through flow cytometry, Western blot and qPCR analysis, ROS and NLRP3 imflammasome were detected. Result shown that the production of ROS was increased by S. aureus , Se exerted strong inhibitory effects on the production of ROS; The protein expression of NLRP3 inflammasome including NLRP3, ASC and Caspase-1 increased significantly after S. aureus infection, Se played an important role in regulating the expression of NLRP3, ASC and Caspase-1; To further investigate the anti-inflammatory effect of Se, the expression level of IL-1β associated molecule pro-IL-1β and IL-1β were detected. Result shown that the mRNA expression of IL-1β was up-regulated by S. aureus and after Se treatment the expression level of IL-1β mRNA was markedly down-regulated, meanwhile Se play a regulation effect on the protein expression of Pro-IL-1β and IL-1β. Conclusions Here we show that ROS is involved in bMECs inflammation induced by S. aureus and Se ameliorates S. aureus -induced inflammation through ROS-mediated NLRP3 pathway in bMECs.

The aim of this study was to determine the characteristics of the gel formula based on it�s organoleptic properties, pH, viscosity, dispersion and homogenity by stability test carried out using the cycling test method and to determine the anti-inflammatory activity of the Xestospongia Sp. in male white mice (Mus musculus) by creating an artificial edema on the mice left foot induced by 1% ?-carrageenan. The gel formula from the ethanol extract of Xestospongia Sp. sponge was physically stable in terms of its organoleptic observation, homogenity, pH and viscosity test. However, the results that were obtained after dispersion test did not fulfill the requirements. In this study, the gel formula of the ethanol extract of Xestospongia Sp. sponge was administered on the mice left foot by using the variations in extract concentration of 0.02%, 0.03%, and 0.04%, and the gel without extract as a negative control and Galtaren�gel (1% Diclofenac Sodium) as a positive control. The evaluated data were in the form of mice leg edema volume measured based on its percent of inflammation and percent of inflammatory inhibition and observed for 360 minutes. The data were analyzed by using the Kruskal-Wallis test followed by the Mann-Whitney test with a confidence level of 95%. The results of this study showed that the gel formula of ethanol extract of Xestospongia Sp. sponge has an anti-inflammatory effect on each concentration and the formula that has a large anti-inflammatory effect was obtained at extract concentration of 0.04%.

Physalis peruviana calyces are used extensively in folk medicine. The crude ethanolic extract and some fractions of calyces were evaluated in order to explore antioxidant and anti-inflammatory activities. The anti-inflammatory activity was evaluated by the TPA-induced ear edema model. The antioxidant in vitro activity was measured by means of the superoxide and nitric oxide scavenging activity of the extracts and fractions. The butanolic fraction was found to be promising due to its anti-inflammatory and antioxidant activities. Therefore, a bio-assay guided approach was employed to isolate and identify rutin (1) and nicotoflorin (2) from their NMR spectroscopic and MS data. The identification of rutin in calyces of P. peruviana supports the possible use of this waste material for phytotherapeutic, nutraceutical and cosmetic preparations.
