Fucosylated chondroitin sulfate CD was isolated from the sea cucumber Cucumaria djakonovi collected from the Avachinsky Gulf of the eastern coast of Kamchatka. Structural characterization of CD was performed using a series of non-destructive NMR spectroscopic procedures. The polysaccharide was shown to contain a chondroitin core [→3)-β-d-GalNAc-(1→4)-β-d-GlcA-(1→]n where about 60% of GlcA residues were 3-O-fucosylated, while another part of GlcA units did not contain any substituents. The presence of unsubstituted both at O-2 and O-3 glucuronic acid residues in a structure of holothurian chondroitin sulfate is unusual and has not been reported previously. Three different fucosyl branches Fucp2S4S, Fucp3S4S and Fucp4S were found in the ratio of 2:1:1. The GalNAc units were mono- or disulfated at positions 4 and 6. Anti-inflammatory activity of CD was assessed on a model of acute peritoneal inflammation in rats. About 45% inhibition was found for CD, while a structurally related linear chondroitin sulfate SS from cartilage of the fish Salmo salar demonstrated only 31% inhibition, indicating that the presence of sulfated fucosyl branches is essential for anti-inflammatory effect of chondroitin sulfates of marine origin.

A series of Etodolac hydrazone derivatives were synthesized and evaluated for their anti-inflammatory activity by using egg white induced paw edema method. All the synthesized target compounds were characterized by CHN- microanalysis, FT-IR spectroscopy and 1HNMR analysis. The synthesized target compounds (P1-P3) were found to be active in reducing paw edema thickness and their anti-inflammatory effect was comparable to that of the standard (Etodolac). Keywords: Etodolac hydrazone derivatives, anti-inflammatory, paw edemamethod.

Introduction: Evaluation of anti-inflammatory action of Codelac® Broncho with Thymus Serpyllum (elixir) in comparison with Fenspiride was carried out on the model of acute carrageenan inflammation of the paws in rats. Materials and methods: Edema was caused by subplantar injection of 0.1 ml of 1% λ- carrageenan gel into the hind paw. The severity of edema was assessed by using 37140 plethysmometer (UGO BASILE, Italy). The measurements were performed before edema induction and 1, 2, 4, 12, 24, 48, 72, 96 and 120 hours afterwards. Anti-inflammatory activity of the drugs was also evaluated based on the analysis of rats’ blood, C-reactive protein concentration and histological examination results. Results and discussion: A decrease in the paw volume increment was revealed in the group with the studied drug in comparison with the group with the carrageenan edema model (control) 4, 12, 24 hours after injection of carrageenan (p<0.05). As a result of plethysmometry, a more pronounced anti-inflammatory effect of the studied drug than that of Fenspiride was revealed. There was a significant decrease in the levels of leukocytes (p<0.05), lymphocytes (p<0.05), monocytes (p<0.05) and neutrophils (p<0.05) in the group with the studied drug compared to those the the control 48 hours after the initiation of edema, while in the group with Fenspiride, there was only a decrease in the levels of leukocytes (p<0.05) and lymphocytes (p<0.05). There were no differences in the concentration of C-reactive protein between the groups. Conclusion: The obtained data indicate a more pronounced anti-inflammatory activity of Codelac® Broncho with Thymus Serpyllum in comparison with Fenspiride, on the model of acute carrageenan inflammation of the paw in rats.

Abstract The genus Galphimia is widely distributed in Mexico, and is represented by 22 species, including medicinal species. The sedative and anti-inflammatory effects of galphimines produced by the species Galphimia glauca have been documented. Formerly, molecular studies using DNA barcodes demonstrated that nine populations botanically classified as Galphimia glauca belong to four different species of the genus Galphimia, and that only one exhibited the sedative properties; however, all the collected species showed anti-inflammatory activity. Other bioactive compounds like quercetin, galphins, galphimidins and glaucacetalins have been identified from methanolic extracts of plants botanically classified as Galphimia glauca. The aim of this work was to determine the anti-inflammatory activity of methanolic extracts of nine collected Galphimia spp. populations grown in Mexico. The possible modes of action were analyzed by evaluating the inhibition of LPS-induced inflammation processes both in vitro and in vivo. The nine populations were evaluated by an in vitro model using RAW 264.7 murine macrophage cells, and two populations (a galphimine-producing and a non-galphimine-producing population) were selected for the in vivo experiments of systemic inflammation and neuroinflammation in mice. Results suggest that an anti-inflammatory in vitro effect was present in all the studied populations, evidenced by the inhibition of nitrite production. An inhibitory systemic inflammation in mice was exerted by the two analyzed populations. In the neuroinflammation model, the anti-inflammatory effect was demonstrated in methanolic extract of the non-galphimine-producing population. For the populations of Galphimia spp. studied herein, the anti-inflammatory effect could not be correlated to the presence of galphimines.

Anti-inflammatory refers to group of medication that is utilized for curing pain and inflammation. Many synthetic products are used as anti-inflammatory agents but the effects caused by them is not satisfactory. Cordis obliqua is an anti-inflammatory herb that is enormously involved in pain reduction. The present paper aims to develop a topical gel formulation comprising herbs i.e. Cordis obliqua and curcumin with potent anti-inflammatory activity. The gel formulation was then subjected to characterization studies which involve pH, viscosity, excrudability, spreadability and in vitro analysis. pH of gel formulation was found to be 7.2±1.01 which is almost equivalent to the skin pH. In viscosity test, it was observed that viscosity of gel formulation was found to be effective. Moreover, spreadability co-efficient of the formulation satisfactory which indicates that sanitizer gel easily adhers on the skin and covers the bacteria residing on the skin, if any.

We investigated the anti-inflammatory activity ofSenecio salignus. This medicinal plant is often used in Mexico for the treatment of fever and rheumatism. Chloroform and methanol extracts of the plant were tested on 12-O-tetradecanoylphorbol-13-acetate- (TPA-) induced edema in mice ears. The methanol extract of the plant inhibited edema by36±4.4% compared with the control, while the chloroform extract exhibited an even greater level of inhibition (64.1%). The chloroform extract was then fractionated, and the composition of the active fraction was determined by GC-MS. The anti-inflammatory activity of this fraction was then tested on TPA-induced ear edema in mice, and we found that the active fraction could inhibit edema by 46.9%. The anti-inflammatory effect of the fraction was also tested on carrageenan-induced paw edema in rats at doses of 100 mg/kg; a58.9±2.8% reduction of the edema was observed 4 h after administration of carrageenan, and the effect was maintained for 5 h.

In this study, we aimed at evaluating in vitro and in vivo anti-inflammatory activity of various extracts of the rhizomes of Globba pendula Roxb. Three extracts ( n-hexane, ethyl acetate, and water) were screened for their inhibitory effect on NO production by lipopolysaccharide-stimulated RAW 264.7 macrophages. The ethyl acetate extract of G. pendula rhizomes (EGP) showed a potential effect with an IC50 value of 32.45 µg/mL. For in vivo study, the ethyl acetate extract was further investigated for its anti-inflammatory effect using collagen antibody-induced arthritic mice (CAIA). The level of arthritis in experimental mice significantly reduced ( P < .05) after treatment with EGP at a dose of 500 mg/kg body weight (b.w.). This study also revealed that EGP is orally non-toxic. Ethyl p-methoxy cinamate was identified as the main constituent of EGP, which may result in its anti-inflammatory effect.

Introduction: Pain is an immunological response to any infection or inflammation and long term use of pain management therapy includes use of Nonsteroidal anti-inflammatory drugs which is associated with occurrence of toxicity as well as gastrointestinal bleeding. Therefore, the investigation of new analgesic and anti-inflammatory agents remains a major challenge. Aims: The objective of this research study is to undergo the pharmacological evaluation of newly synthesized benzoxazole derivatives. These novel derivatives were evaluated for anti-nociceptive, anti-inflammatory and cytotoxic activity using various in-vivo and ex-vivo methods. Methods: The study was carried out using swiss mice (adult male) weighing between 20gm to 30gm and were divided into groups containing (n=6) six animals in each group for treatment. The anti-nociceptive activity was performed by using 0.1ml of 0.6% v/v acetic acid as nociception inducer and evaluated by the diminished number of abdominal writhes. The anti-inflammatory activity was done using 0.1 ml of 2% w/v Carrageenan induced paw edema method was observed which was evaluated by calculating the percent maximum possible effect. Histopathological evaluation and cytotoxic activity of the compounds was carried out. Results: The results of this research study revealed that synthesized derivatives (a, b, c, d and e) showed promising anti-nociceptive and anti-inflammatory effect along significantly higher cytotoxic activity in MCF-7 cell lines. Conclusion: It can be concluded that synthesized derivatives (a, b, c, d and e) have potential anti-nociceptive and anti-inflammatory effect along with cytotoxic activity and certain modification in structure may result in potent activity.

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.
