Mast cells are unique immune cells involved in allergic reactions, but also in immunity and inflammation. Interleukin 37 (IL-37) has emerged as an important regulatory cytokine with ability to inhibit immune and inflammatory processes. IL-37 is made primarily by macrophages upon activation of toll-like receptors (TLR) leading to generation of mature IL-37 via the action of caspase 1. In this review, we advance the premise that mast cells could regulate the anti-inflammatory activity of the IL-37 via their secretion of heparin and tryptase. Extracellular IL-37 could either dimerize in the presence of heparin and lose biological activity, or be acted upon by proteases that can generate even more biologically active IL-37 forms. Molecules that could selectively inhibit the secretion of mast cell mediators may, therefore, be used together with IL-37 as novel therapeutic agents.

Inflammation is a physiological process involved in the defenses of the body and the repair of tissues. It is acutely activated by infections, trauma, toxins, or allergic reactions. However, if it becomes chronic, inflammation can end up stimulating the development of diseases such as cardiovascular disease, autoimmune disease, neurological disease, or cancer. Additionally, during aging, inflammation becomes increasingly more chronic. Furthermore, we found that certain foods, such as saturated fats, have pro-inflammatory activity. Taking this into account, in this review we have discussed different diets with possible anti-inflammatory activity, the commonly ingested components of each diet and their active compounds. In addition, we have proposed some dietary guidelines, as well as a list of compounds present in foods with anti-inflammatory activity, outlining how to combine them to achieve optimal anti-inflammatory effects. Therefore, we can conclude that the compounds in our diet with anti-inflammatory activity could help alleviate the inflammatory processes derived from diseases and unhealthy diets, and thereby promote healthy aging.

Background: Recently, there has been a lot of scientific interest in exploring the syntheses of oxygen and nitrogen-containing heterocyclic compounds due to their pharmacological activities. In addition, benzisoxazoles play a very important role in organic synthesis as key intermediates. Objective: In this paper, we focused on developing a novel synthetic route for biologically active arylisoxazoles under normal conditions, and simplified it to get high purities and yields, and also reported their anti-inflammatory activities. Method: An efficient and simple method has been explored for the synthesis of novel 3-methyl arylisoxazoles from o-nitroaryl halides via o-ethoxyvinylnitroaryls, using dihydrated stannous chloride (SnCl2.2H2O) in MeOH / EtOAc (1:1) via Domino rearrangement in one pot synthesis. Result: We synthesized novel 3-methylarylisoxazoles from o-nitroarylhalides via o-ethoxyvinylnitroaryls, using dihydrated stannous chloride (SnCl2.2H2O) in MeOH / EtOAc (1:1) via domino rearrangement. In this reduction, nitro group and ethoxy vinyl group change to the functional acyl ketones, followed by hetero cyclization. Here, the reaction proceeds without the isolation of intermediates like 2-acylnitroarenes and 2- acylanilines. All the synthesized compounds were completely characterized by the NMR and mass spectra. The compounds were also explored for their anti-inflammatory activity by carrageenan-induced inflammation in the albino rats (150-200 g) of either sex used in this entire study with the use of Diclofenac sodium as the standard drug. The initial evaluations identified leading targets with good to moderate anti-inflammatory activity. Conclusion: A simple, one-pot and convenient method has been explored for the synthesis of novel 3- methylarylisoxazoles with high purity and reaction yields. All the compounds 3a, 3c, 3d, 3f, 3g and 3h exhibited 51-64% anti-inflammatory activities.

Everyone knows that forest air is very good for health, and one of the most important reasons for this is the presence of phytoncides in it, which kill or suppress pathogens and have a healing effect. Also, phytoncides are one of the factors of the natural immunity of plants (plants sterilize themselves with the products of their vital activity). Their large number is allocated by plants. One of them is the common bird cherry. Cherry-a representative of the genus of plums of the Rosaceae family. The view includes low trees and shrubs. Cheremukha-forest orderly. Its flowers and leaves are rich in phytoncides, thanks to which they exude an alluring aroma. However, when they break down, they release prussic acid, which is dangerous for all living things. This gave them the opportunity to attract and destroy pests. Phytoncides are volatile biologically active substances formed by plants that kill or inhibit the growth and development of bacteria, microscopic fungi, and protozoa. In addition to all of the above, bird cherry has exceptional properties. The strong, somewhat intoxicating scent of flowers and leaves cleanses the air of germs. Antimicrobial properties of phytoncides have led to a large number of studies on their use in medicine, veterinary medicine, plant protection, storage of fruit and vegetable products, in the food industry and other areas of practice. Almost all parts of the plant have bactericidal, fungicidal and insecticidal properties. In folk medicine, bird cherry has long been used as an astringent, fixing, anti-inflammatory and anti-scurvy agent. Bird cherry produces the most powerful phytoncides containing prussic acid. Protozoa die under the influence of bird cherry phytoncides in 5 minutes. On the basis of numerous studies, the time of death of protozoa after noncontact exposure to phytoncidal plants has been established. Especially a lot of phytoncides are released by young leaves in spring and summer, in autumn phytoncides are released much less. The presence of tannins and essential oil in the fruit has an anti-inflammatory effect, which is used to treat inflammatory processes in the gastrointestinal tract and dysentery. The infusion of cherry fruits has a destructive effect on microorganisms. Preparations of the fruits of the common cherry have an antiseptic effect. They are used in dental practice in the treatment of inflammatory processes of the oral mucosa, paradontosis, toothache and hypovitaminosis.

Annotation. Polymorphism among biologically active substances is an extremely important factor that modifies the therapeutic properties of pharmaceutical substances and dosage forms, significantly affects the parameters of their biological activity and pharmacokinetics. Chemical synthesis among the derivatives of 4-R-2,2-dioxo-1H-2λ6,1-benzothiazine-3-carboxylic acids gave the leader compound N-(4-trifluoromethylphenyl)-4-hydroxy-2,2-dioxo-1H-2λ6,1-benzothiazine-3-carboxamide, the crystalline polymorph of which in the form of plates has a pronounced analgesic activity. The aim of the study was to investigate the anti-inflammatory activity of compound B by its effect on various components of the inflammatory reaction, as well as the antipyretic effect of this compound in rats. The anti-alterative activity was determined on the model of planar skin wounds, the antiproliferative effect - on the model of cotton granuloma, the anti-exudative effect - on the model of toxic pulmonary edema in rats. The antipyretic effect was studied in a model of milk fever in rats. The study was performed on 91 white male Wistar rats. Statistical processing of the obtained results was performed using the program "STATISTICA 6.1" by methods of variation statistics using parametric and nonparametric methods. The results showed that the polymorphic compound B has anti-inflammatory activity on all components of the inflammatory reaction - alteration, exudation and proliferation. In terms of efficacy in the model of experimental inflammation, this substance is superior to meloxicam, as its ED50 when administered orally is 5.2 mg/kg, while the reference drug - 9.1 mg/kg. Compound B exhibits a pronounced antipyretic effect in a rat fever model. Therefore, the polymorphic modification of the carboxamide derivative in the form of plates is promising for further research in order to create on its basis a drug with analgesic, anti-inflammatory and antipyretic properties.

Rhizome of bangle (Zingiber cassumunar Roxb.) is one of the materials that are traditionally used in the traditional preparation to maintain skin from redness. The content of chemical compound in bangle rhizomes has many benefits, including inhibition of the inflammatory processes. This study aims to determine the topical anti-inflammatory activity of ethanolic extract of bangle rhizomes in mice induced by carrageenan. Thirty five female Swiss mice were used in this study. Animals were divided into 7 group of five: normal group, carrageenan 2% group, carrageenan 2% group plus control of basis (Biocream®), carrageenan 2% group plus 2.5% hydrocortisone cream, and carrageenan 2% group plus cream of ethanolic extract of bangle rhizomes with the concentration of 1%, 2.5% and 5% w/w. Carrageenan 2% was injected subcutaneously in all treatment group except normal group. The skinfold thickness of mice was measured every 1 hour for 6 hours after carrageenan injection. Results of this study shows that there is a significant differences between treatment groups (p <0.05) compared to carrageenan 2% treated group. To conclude, ethanolic extract of bangle rhizomes has topical anti-inflammatory in mice induced by carrageenan.

Inflammatory Effect

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.
