Este trabajo se fundamenta en la evaluación de la actividad antiinflamatoria de extractos de sofrito de tomate, así como de compuestos estándares de la dieta mediterránea, usando un modelo experimental optimizado basado en larvas de pez cebra. La migración de neutrófilos en larvas de pez cebra de 96 horas post fertilización se indujo mediante una lesión y se potenció añadiéndole lipopolisacárido, dicha migración se visualizó y cuantificó mediante análisis de imagen. El efecto antiinflamatorio del extracto de tomate y de los compuestos utilizados fue correlacionado porcentualmente por la disminución de la migración de los neutrófilos. Los resultados muestran que el extracto de tomate presentó una reducción en la migración de neutrófilos de 40 % respecto al grupo control. Por otra parte, el ácido clorogénico y la cianidina presentes en el sofrito de tomate utilizados como estándares presentaron una disminución de la migración de neutrófilos de un 66,7 % y 62,5 % respectivamente. Estos porcentajes son comparables a los resultados observados en ensayos con drogas antiinflamatorias como la indometacina y piroxicam. Los resultados muestran que el extracto de sofrito de tomate presenta posible actividad antinflamatoria demostrada por la reducción de la migración de neutrófilos, además el modelo se mostró sensible y válido para ser aplicado en matrices alimentarias complejas. The main of this study was to evaluate the anti-inflammatory activity of tomato sofrito extracts, as well as standard compounds present in the Mediterranean diet, using an optimized experimental model based on zebrafish larvae. Neutrophil migration in zebrafish larvae 96 hours post fertilization was induced by a cut in the caudal fin and enhanced by adding lipopolysaccharide and was visualized and quantified by image analysis. The anti-inflammatory effect of tomato extract and the compounds used was correlated by the percentage decrease in the migration of neutrophils. The results showed that, tomato extract showed a reduction in neutrophil migration of 40% compared to the control group. Moreover, chlorogenic acid and cyanidin present in tomato sofrito sauce showed a decrease in neutrophil migration of 66.7% and 62.5% respectively. These percentages are comparable to the results observed in trials with anti-inflammatory drugs such as indomethacin and piroxicam. The results show that tomato sofrito extract has possible anti-inflammatory activity demonstrated by the reduction of neutrophil migration, furthermore the model was sensitive and valid to be applied in complex food matrices.

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.

In the last decade, high cariesprophylactic efficacy of ammonium hexafluorosilicates, including salts with substituted biologically active ammonium cations, has been demonstrated. Among the promising anti-caries agents are recently synthesized 2-, 3-, 4-carboxymethylpyridinium hexafluorosilicates, for whose cations anti-inflammatory activity is expected. The aim of the work is to assess the presence of anti-inflammatory activity in the series of 2-, 3-, 4-carboxymethylpyridinium hexafluorosilicates in the experiment. 2-, 3-, 4-Carboxymethylpyridinium hexafluorosilicates (I–III, respectively) were synthesized according to the previously proposed technique, carrageenan is a commercial preparation, reference drug is a indomethacin. Experiments on the anti-inflammatory activity of hexafluorosilicates were performed on 77 white Wistar male rats weighing 174–190 g using the carrageenan model of inflammation. The inflammatory reaction was reproduced by subplantary administration of 0.1 ml of a 0.2% solution of carrageenan, the studied compounds were administered orally in doses 1/10, 1/20, 1/50 from LD50 for the compound III. It was established that after administration of carrageenan, animals of the control group showed marked paw edema, which gradually increased and was maximal after 24 hours of observation. According to the data obtained, the indices for compounds I-III practically do not differ from those of the control group. This indicates that, despite the results of the PASS forecast and the presence of acetic acid residue, an anti-inflammatory pharmacofor, in compounds I-III, the compounds under study do not have an anti-inflammatory effect in the carrageenan model. 2-, 3-, 4-Carboxymethylpyridinium hexafluorosilicates do not show the expected anti-inflammatory activity in the carrageenan model of inflammation.

The article presents the results of determining anti-inflammatory activity of the spray based on ibuprofen and liquid wormwood extract. Anti-inflammatory activity was studied on the model of local acute carrageenan inflammation. As a result of the studies it was found that the increase in paw weight averaged 49,66% in the control group of rats, in the group of rats receiving the comparison drug «Ibuleve» - 11,26%. For the group of rats receiving combined composition and the same composition without ibuprofen, the average increase in paw weight was 7,11% and 15,07%, respectively. The index of inflammatory inhibition when using combined composition was 85,68%, the composition with liquid extract of wormwood without ibuprofen was 69,65%, the liquid extract of wormwood 1:1 was 53,00%. The index of edema suppression proves that combined composition of the spray containing ibuprofen and liquid extract of wormwood has the most pronounced anti-inflammatory effect, for which the percentage of edema suppression exceeds the value for the comparison drug on the average by 8,36%.

Berchemia floribunda (Wall.) Brongn. (BF), which belongs to Rhamnaceae, is a special plant of Anmyeon Island in Korea. BF has been reported to have antioxidant and whitening effects. However, the anti-inflammatory activity of BR has not been elucidated. In this study, we evaluated the anti-inflammatory effect of leaves (BR-L), branches (BR-B) and fruit (BR-F) extracted with 70% ethanol of BR and elucidated the potential signaling pathway in LPS-induced RAW264.7 cells. BR-L showed a strong anti-inflammatory activity through the inhibition of NO production. BR-L significantly suppressed the production of the pro-inflammatory mediators such as iNOS, COX-2, IL-1β, IL-6 and TNF-α in LPS-stimulated RAW264.7 cells. BR-L suppressed the degradation and phosphorylation of IκB-α, which contributed to the inhibition of p65 nuclear accumulation and NF-κB activation. BR-L obstructed the phosphorylation of MAPKs (ERK1/2, p38 and JNK) in LPS-stimulated RAW264.7 cells. Consequently, these results suggest that BR-L may have great potential for the development of anti-inflammatory drugs to treat acute and chronic inflammatory disorders.

Inflammatory Effect

Inflammation is a normal protective response to tissue injury caused by physical trauma, damaging chemicals, or microbiological substances. Steroids and nonsteroidal anti-inflammatory drugs have many side effects, so there are many anti-inflammatory developments originating from natural ingredients, especially in plants. Plants that are scientifically proven to have anti-inflammatory properties, namely turmeric (Curcuma domestica Val.) The method used in this literature study is a review of various journals published online, with the keyword turmeric as an anti-inflammatory, reviewed one by one and then the journals obtained are collected and information created by summarizing the content and then comparing the journals to be used as references. The results showed that turmeric tested had anti-inflammatory activity. The strength of the anti-inflammatory effect is shown by the carrageenan induction method which inhibits endema in rat feet and inflammation in the liver using the method of induction by diethylnitrosamine in this plant varies, depending on the dose. Compounds that are considered to provide anti-inflammatory activity are curcumin class compounds because they can inhibit the formation of prostagladin, thromboxan, and prostagycycline by inhibiting the activity of the cyclooxygenase enzyme. Curcumin also inhibits the formation of leuketrien compounds by inhibiting the activity of the lipoxygenase enzyme.Keywords: Anti-inflamatoryTurmericCucurminABSTRAK Inflamasi merupakan perlindungan normal ketika timbul luka jaringan karena zat mikrobiologi, zat kimia atau trauma fisik.

The level of expression of anti-inflammatory cytokines NF-kB, IL-6, IFN-y, Caspasa-3, FC in chickens in the lungs and intestines during the modeling of infectious bronchitis in chickens was studied. To simulate coronavirus pneumonia, the vaccine was administered individually, 10 doses per head orally. The chickens of the 1st experimental group were fed with the Lyumantse preparation at the rate of 3 kg / t of feed, the 2nd experimental group received the Glitsevir drug at the rate of 200 μg / 0.3 ml per head. The chickens of the control group did not receive the preparations. It was revealed that antiviral drugs in the experimental groups suppressed the destruction of epithelial cells in the intestine. This may not always be an indication of a positive character, as in the case of apoptosis, not only the intestinal cells affected by the virus particles but also healthy cells are destroyed. There was a decrease in the number of active macrophages in the intestines of the experimental groups relative to the control. The amount of interferon produced was also below the control, which indicates a decreased activity of the immune system. A higher pro-inflammatory activity in the respiratory system of chickens was detected when Glicevir was used. It consists of increased expression of IL-6, interferon-gamma, macrophage receptor to Fc antibody fragments and inflammatory regulatory factor NF-kB genes compared to Lumantse with anti-inflammatory activity, but also compared to untreated control group chickens. It is concluded that it is possible to predict the risk of an exacerbation of an infectious process in the lungs against the background of a local decrease in the viral load in the intestine. An integrated approach is needed in the treatment of coronavirus infections, including either systemic antiviral drugs or anti-inflammatory drugs.

In the experiment in a model of acute formalin-induced inflammation of rat paw, the changes of size of the affected limbs (paw edema) and parameters of leukogram were registered. The anti-inflammatory effect of antihypoxants (amtizol, hesperidin, hypoxen, metaprot) was investigated. It has been shown that hypoxen 50 mg/kg have weak anti-inflammatory activity, but potentiate the effect of nonsteroid anti-inflammatory drugs. At simultaneous enteral administration of hypoxen with acetylsalicylic acid or diclofenac, evident anti-inflammatory effect was marked, that was manifested by significant reduction in registered inflammation symptoms.

Privileged Structures

Rheumatoid arthritis, arthrosis and gout, among other chronic inflammatory diseases are public health problems and represent major therapeutic challenges. Non-steroidal anti-inflammatory drugs (NSAIDs) are the most prescribed clinical treatments, despite their severe side effects and their exclusive action in improving symptoms, without effectively promoting the cure. However, recent advances in the fields of pharmacology, medicinal chemistry, and chemoinformatics have provided valuable information and opportunities for development of new anti-inflammatory drug candidates. For drug design and discovery, thiophene derivatives are privileged structures. Thiophene-based compounds, like the commercial drugs Tinoridine and Tiaprofenic acid, are known for their anti-inflammatory properties. The present review provides an update on the role of thiophene-based derivatives in inflammation. Studies on mechanisms of action, interactions with receptors (especially against cyclooxygenase (COX) and lipoxygenase (LOX)), and structure-activity relationships are also presented and discussed. The results demonstrate the importance of thiophene-based compounds as privileged structures for the design and discovery of novel anti-inflammatory agents. The studies reveal important structural characteristics. The presence of carboxylic acids, esters, amines, and amides, as well as methyl and methoxy groups, has been frequently described, and highlights the importance of these groups for anti-inflammatory activity and biological target recognition, especially for inhibition of COX and LOX enzymes.

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.

Neuroinflammation is an integral part of epilepsy pathogenesis and other convulsive conditions, and non-steroidal anti-inflammatory drugs (NSAIDs) present a potent tool for the contemporary search and design of novel anticonvulsants. In the present paper, evaluation of the anticonvulsant activity of the potential NSAID dual COX-2/5-LOX inhibitor darbufelone methanesulfonate using an scPTZ model in mice in dose 100 mg/kg is reported. Darbufelone possesses anticonvulsant properties in the scPTZ model and presents interest for in-depth studies as a possible anticonvulsant multi-target agent with anti-inflammatory activity. The series of 4-thiazolidinone derivatives have been synthesized following the analogue-based drug design and hybrid-pharmacophore approach using a darbufelone matrix. The synthesized derivatives showed a significant protection level for animals in the scPTZ model and are promising compounds for the design of potential anticonvulsants with satisfactory drug-like parameters.
