The article emphasizes the anti-inflammatory effects of herbal extracts on different experimental models that are repeatedly used to test the in vivo anti-inflammatory activity of herbal components. Edema, granuloma and arthritis models are used to test the anti-inflammatory activity of plant extracts whereas formalin or acetic acid-induced writhing test and hot plate methods are the most repeatedly used to evaluate anti-nociceptive potentials of the herbal extracts. Although adjuvant-induced and collagen-induced arthritis models are also quite efficient, they have been used seldom to evaluate anti-inflammatory tendencies of the herbs. Here, we suggest a double positive reference model using both steroid and nonsteroidal anti-inflammatory drugs at the same time, instead of using only one of them either.

Chinese yam ( Dioscorea opposita), peeled or whole, is a popular food item that is considered to be healthy. Often, the yam is peeled before cooking. However, it is also consumed with peel. Therefore, in this study, the peel of this yam was extracted sequentially with n-hexane, ethyl acetate and methanol, and studied for its health-benefits, using in vitro bioassays. Bioactivity-guided purifications of extracts of the peel afforded phenanthrenes (1-4), as characterized by spectroscopic methods. Phenanthrene 1 is a novel analogue. The extracts and isolates were tested for anti-inflammatory activity using cyclooxygenase enzyme (COX-1 and -2) inhibitory assays. All phenanthrenes isolated from the yam peel showed higher inhibition of COX enzymes than the over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) aspirin, ibuprofen and naproxen.

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.

Introduction and Aim: The most emerging area of research in nanotechnology deals with the synthesis of nanoparticles which are of great importance due to its use in various biological fields. Myristica fragrans is commonly known as “nutmeg”. It is popular as a spice and also possesses various therapeutic properties. It has a characteristic pleasant fragrance and a slightly warm taste. It has various therapeutic uses and is widely used. The aim is to assess the anti-inflammatory activity of nutmeg oleoresin mediated silver nanoparticles. Materials and Methods: The nutmeg oleoresin mediated silver nanoparticles were synthesized and was confirmed by UV Vis spectroscopy. The anti-inflammatory property of the prepared nutmeg oleoresin mediated silver nanoparticles was assessed using albumin denaturation inhibitory assay technique. Results: The nutmeg oleoresin mediated silver nanoparticles showed good anti-inflammatory activity with increasing concentration of the nanoparticles. Conclusion: Although a variety of steroidal and non-steroidal anti-inflammatory drugs have been developed, researchers are focusing on natural substances to develop new anti-inflammatory agents. Nutmeg mediated silver nanoparticles showed a good range of inhibition and can be used against inflammation. The myristicin present in the nutmeg maybe responsible for its anti-inflammatory action. Increased albumin denaturation is reported in conditions like in rheumatoid arthritis, diabetes and cancer. Hence this may pay way to manage such conditions.

Chronic inflammation contributes to multiple ageing-related musculoskeletal and neurodegenerative diseases, cardiovascular diseases, asthma, rheumatoid arthritis, and inflammatory bowel disease. More recently, chronic neuroinflammation has been attributed to Parkinson’s and Alzheimer’s disease and autism-spectrum and obsessive-compulsive disorders. To date, pharmacotherapy of inflammatory conditions is based mainly on nonsteroidal anti-inflammatory drugs which in contrast to cytokine-suppressive anti-inflammatory drugs do not influence the production of cytokines such as tumour necrosis factor-α or nitric oxide. However, their prolonged use can cause gastrointestinal toxicity and promote adverse events such as high blood pressure, congestive heart failure, and thrombosis. Hence, there is a critical need to develop novel and safer nonsteroidal anti-inflammatory drugs possessing alternate mechanism of action. In this study, plants used by the Dharawal Aboriginal people in Australia for the treatment of inflammatory conditions, for example, asthma, arthritis, rheumatism, fever, oedema, eye inflammation, and inflammation of bladder and related inflammatory diseases, were evaluated for their anti-inflammatory activity in vitro. Ethanolic extracts from 17 Eucalyptus spp. (Myrtaceae) were assessed for their capacity to inhibit nitric oxide and tumor necrosis factor-α production in RAW 264.7 macrophages. Eucalyptus benthamii showed the most potent nitric oxide inhibitory effect (IC50  5.57±1.4 µg/mL), whilst E. bosistoana, E. botryoides, E. saligna, E. smithii, E. umbra, and E. viminalis exhibited nitric oxide inhibition values between 7.58 and 19.77 µg/mL.

Synthetic Non-steroidal anti-inflammatory drugs (NASAIDs) are the choice of drug for inflammation. NASAIDs caused severe side effects like hyperacidity, gastric ulcer and so on. To avoid the side effects of NASAIDs, there is an urgent need for searching new molecule from natural origin. Present study is therefore aimed to explore Grevillea robusta A. Cunn, ex R.Br. Family proteaceae leaves for anti-inflammatory activity. Microscopic measurement (fibre length and width), Ash values and extractive values of Grevillea robusta leaves were determined to set the pharmacognostic standards. Chemical constituents were evaluated through chemical tests. The Ethanol extract of Grevillea robusta leaves (GRLE)) were subjected to evaluate in-vitro anti-inflammatory activity through HRBC method and Heat induced haemolytic method. The leaves of Grevillea robusta showed significant anti-inflammatory activity. The Ethanol extract (GRLE) showed significant anti-inflammatory activities. GRLE was found to contain polyphenols as chemical constituents which was the basis of anti-inflammatory activity. On the basis of result we can conclude that Ethanol extract of leaves of Grevillea robusta has good anti-inflammatory activity. GRLE could be used for treatment of inflammation.

This in vitro study focuses on the green synthesis of selenium nanoparticles using Capparis decidua and its anti-inflammatory activity. Nanotechnology is the speciality associated with Material science and biology, rather than a particular field. It involves the formulation of particles at nanoscale known as Nanoparticles, where they have control over bulk macroscopic properties of the same material. Selenium, being a 'Drug nanocarrier', possesses strong antibacterial, antioxidant and anti-cancer as well as anti-inflammatory properties. As the medicinal plant Capparis decidua possesses a lot of phytochemicals, this study combined it to synthesise selenium nanoparticles, and anti-inflammatory properties were analysed. Synthesis of Selenium nanoparticles using Capparis decidua extract, collection of NPs using centrifugation, analysis of anti-inflammatory using UV spectroscopy and inhibition of Bovine serum albumin denaturation assay were performed. Biosynthesised selenium nanoparticles using Capparis decidua exhibit effective anti-inflammatory properties and act as an alternative candidate for steroidal and non-steroidal anti-inflammatory drugs. On account of performing the Green synthesis of selenium nanoparticles along with the combination of Capparis decidua, it is evident that Capparis decidua possesses effective anti-inflammatory with increasing concentrations up to 5muL. In future, we can encounter further efficacy by raising the concentrations by adding new formulations other than Capparis decidua
