All over the world, non-steroidal anti-inflammatory drugs (NSAIDs) are taken annually by about three hundred million people and this figure is constantly increasing. At the same time, NSAIDs are also one of the most common causes of side effects of drug therapy. The development and implementation of new anti-inflammatory drugs, including those of plant origin, with minimal side effects is an urgent task of modern pharmaceutical science. Vaccinium corymbosum L. (family Ericaceae), which is gaining more and more popularity among berry crops and is successfully cultivated in Ukraine, is promising in this direction for research. The aim: phytochemical analysis of dry extracts from blueberry leaves to establish the possibility of creating new drugs with anti-inflammatory activity. Materials and methods. The objects of the study were dry extracts of northern highbush blueberry leaves. The content of amino acids and phenolic compounds was determined by HPLC and spectrophotometry. The prototypal activity was studied in vivo and in vitro. Research results. 4 dry extracts were obtained from northern highbush blueberry leaves. In the extracts obtained by HPLC, 7 amino acids were identified, including 3 essential ones: arginine, histidine, and phenylalanine. As a result of the HPLC study, 7 phenolic compounds were identified in extracts from the leaves of northern highbush blueberry: 5 flavonoids - rutin, quercetin-3-O-glucoside, kaempferol-3-O-glucoside, quercetin and kaempferol and 2 hydroxycinnamic acids, chlorogenic and caffeic acid. For the first time, the anti-inflammatory effect of extracts from blueberry leaves was investigated. It was revealed that extract 1 at a dose of 50 mg/kg and extract 4 modified with arginine at a dose of 25 mg/kg have the highest anti-inflammatory activity. Conclusions. The results of the conducted studies indicate that extracts from the leaves of northern highbush blueberry in terms of the content of biologically active substances are promising sources for the creation of new drugs and dietary supplements with anti-inflammatory activity

Nonsteroidal anti-inflammatory drugs (NSAIDs) have been widely used for the treatment of inflammation. However, despite their effectiveness, most NSAIDs cause various side effects that negatively affect the management of inflammation and, in part, pain. Thus, there is a need to search for new anti-inflammatory agents with few, or no, side effects. Natural products of plant, animal, or microorganism origin have been good sources of new bioactive compounds. The present study was carried out to evaluate the acute and chronic anti-inflammatory activities of the essential oil of the rhizomes of Zingiber zerumbet (Zingiberaceae) using the carrageenan-induced paw edema and cotton pellet-induced granuloma tests, respectively. The effect of the essential oil on inflammatory- and noninflammatory-mediated pain was also assessed using the formalin test. Essential oil of Z. zerumbet, at doses of 30, 100, and 300 mg/kg, was administered intraperitoneally to rats. The substance exhibited significant anti-inflammatory activity both in acute and chronic animal models. The essential oil also inhibited inflammatory- and noninflammatory-mediated pain when assessed using the formalin test. In conclusion, the essential oil of Z. zerumbet possessed anti-inflammatory activity, in addition to its antinociceptive activity, which may explain its traditional uses to treat inflammatory-related ailments.

Background: Nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most commonly used drugs in the world. The widespread use of NSAIDs is associated with a number of serious side effects and complications observed for both selective and non-selective COX inhibitors. Therefore, the search for new COX inhibitors, which along with their effectiveness will have minimal side effects, is a very important and urgent task. Methods: This work studied the synthesis of new 1,4,5,6-tetrahydropyrimidine-2-carboxamides based on the reaction of 2-morpholin-4-yl-N-(het)aryl-2-thioxoacetamides with 1,3-diaminopropane. All obtained compounds were tested for anti-inflammatory activity in vitro and in silico conditions. All synthesized 1,4,5,6-tetrahydropyrimidine-2-carboxamides were tested for influence on the course of the exudative phase of the inflammatory process based on the carrageenan model of paw edema of laboratory nonlinear heterosexual white rats weighing 220-250 g, using Diclofenac as a reference. Optimization of the geometry of the studied structures and molecular docking was carried out using the ArgusLab 4.0.1 software package. Results: The target products were obtained with yields of 71-98% and easily isolated from the reaction mixture. The best anti-inflammatory activity was found in N-(4-chlorophenyl)-1,4,5,6-tetrahydropyrimidine-2-carboxamide and in N-[4-chloro-3-(trifluoromethyl)phenyl]-1,4,5,6-tetrahydropyrimidine-2-carboxamide, suppression of the inflammatory response was 46.7 and 46.4%, respectively. The results of molecular docking with COX-1 and COX-2 enzymes were in good agreement with the experimental data, R2 ˃ 0.92 and R2 ˃ 0.83, respectively. Conclusion: The compounds under study were shown to be promising as potential anti-inflammatory agents.

Naproxen (Naprosyn - Syntex) and ketoprofen (Orudis - M & B) are new drugs for treating various forms of arthropathy. For both drugs the manufacturers claim good anti-inflammatory activity with a low incidence of unwanted effects, particularly gastric irritation, in comparison with other non-steroidal anti-inflammatory drugs. If these claims can be substantiated these preparations would be valuable. Like aspirin and other non-steroidal anti-inflammatory drugs they both inhibit prostaglandin synthesis. Both are chemically related to other such drugs, for example ibuprofen (Brufen - Boots).

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.

Acetaminophen is a popular antipyretic analgesic medicine that has weaker anti-inflammatory properties and lower incidence of side effects than nonsteroidal anti-inflammatory drugs (NSAIDs). However, acetaminophen causes hepatotoxicity due to the reactive metabolite N-acetyl-p-benzoquinone imine (NAPQI). We have obtained acetaminophen analogues in 57–99% yields by using aniline derivatives with protected α-amino acids and fatty acids via the corresponding mixed carbonic carboxylic anhydrides in aqueous MeCN. We have also succeeded in synthesizing AM404 analogues in 76–97% yields, which are expected to be promising candidates for reducing hepatotoxicity.

To this date nonsteroidal anti-inflammatory drugs play a huge role in the treatment of inflammatory eye diseases. Ophthalmologists face the question of choosing between glucocorticoid drugs (GCS) and nonsteroidal anti-inflammatory drugs (NSAIDs) for the treatment of any inflammatory process. At the same time, these groups can be used both in combinations and in monotherapy mode. Glucocorticoids are widely and effectively used in ophthalmology, but it should be remembered about a number of serious side effects of this group of drugs. When using these drugs, it is possible to increase ophthalmotonus, decrease the immune response and reparative processes, also GCS have cataractogenic and ulcerogenic effects, and therefore it careful use is necessary. NSAIDs are inferior to glucocorticoids in anti-inflammatory activity. Its mechanism of action is associated with blocking cyclooxygenase, inhibition of prostaglandin synthesis from arachidonic acid. In this regard, NSAIDs are the preferred group in the treatment of inflammatory eye diseases. The use of NSAIDs gives a good analgesic effect, this class of drugs is effective for the prevention of macular edema of various etiologies and reducing the risk of inflammation in the postoperative period. One of the most effective and most modern NSAIDs for topical use is a derivative of phenylacetic acid — Bromophenac, which in its formula has a bromine atom, which increases its lipophilicity, penetrating ability into the tissues of the eye, as well as analgesic and anti-inflammatory activity. Bromfenac is effective for relieving pain and all signs of inflammation caused by disease or surgery, suppressing the development of macular edema of various etiologies, has an antimiotic effect. Also, this group can be used after refractive surgery to reduce pain and photophobia, to relieve itching in allergic conjunctivitis. Double use of this drug during the day, the absence of discomfort and minimal side effects contribute to improving the patient’s compliance.
