Objective: The objective of this search was to synthesize a new naproxen analogues having a 1,2,4-triazole-3-thiol heterocyclic ring, and preliminary pharmacological assessment of the anti-inflammatory activity of the synthesized compounds. Methods: The synthesis of naproxen analogues that having 1,2,4-triazole-3-thiol heterocyclic ring occur through esterification of naproxen, and then its reaction with hydrazine hydrate, and carbon disulfide, finally different aromatic aldehydes reacted with triazole derivatives of naproxen containing amino group to produce schiff bases.Results: In vivo acute anti-inflammatory activity of the synthesize compounds (Va-Vd) was evaluated in rats using egg-white induced edema model of inflammation in a dose equivalent to (50 mg/kg) of naproxen. All tested compounds were produced a significant reduction in paw edema with respect to the effect of propylene glycol 50% v/v (control group). Compound Vd produced superior anti-inflammatory activity compared to naproxen.Conclusion: The results obtained in this work give evidence about the valid synthesis of 1,2,4 triazole-3-thiol derivatives of naproxen, which reacted with different aldehydes to yield several schiff bases. The incorporation of benzaldehyde possess para-electron donating group (para-hydroxyl benzaldehyde) will increase the anti-inflammatory activity of naproxen.

Objective: The present study was conducted to evaluate anti-inflammatory activity of Ariflex liniment (conceptualized and developed by Ari Healthcare Pvt. Ltd) in comparison with Diclofenac gel in carrageenan induced rat paw edema model. Methods: Wistar rats of either sex weighing 150-180 g were taken and divided into 3 groups with 6 animals in each group i.e. Group 1 (Controlled Group), Group 2 (Diclofenac gel) and Group 3 (Ariflex liniment). The study drugs were topically applied 30 min prior to carrageenan injection. After 30 min 1% w/v of 0.05 ml carrageenan was injected subcutaneously in the paw. The paw was marked with ink at the level of lateral malleolus and immersed in mercury up to the lateral malleolus mark. The paw volume was measured plethysmographically, immediately after injection i.e. on 0 min, and then on 30 min,1h, 2h,3h, 4h and 5hr after injection. Results: Diclofenac gel sodium treated group showed significant inhibition (p<0.01) of paw edema at 30 min, 1, 2, 3, 4 and 5th hrs as compared to control group. Ariflex Liniment showed significant inhibition (p<0.05) of paw edema at 30 min, 1, 2, 3, and 4th hrs as compared to the control group. Group treated with Ariflex Liniment did not show any significant decrease in paw edema volume at 5th hrs when compared to the control group. Conclusion: Ariflex Liniment possesses anti-inflammatory activity.

The purpose of study is to formulate and evaluate ufasomal gel of dexamethasone. Ufasomal suspension was made by sonication method using different concentrations of Span 80, Span 20 and cholesterol along with 25 mg of drug. Ufasomal gel was formulated by hydration method using carbopol 940. Ufasomal vesicles appeared as spherical and multilamellar under Transmission Electron Microscope. Ufasomal formulation prepared with drug to oleic acid molar ratio 8:2 (UF-2) produced greater number of vesicles and greater entrapment efficiency. UF-2 was optimized for further evaluation. The transdermal permeation and skin partitioning of from optimized formulation was significantly higher () as compared to plain drug and plain gel formulation which is due to presence of surfactant acting as permeation enhancer. Permeation of optimized formulation was found to be about 4.7 times higher than plain drug gel. Anti-inflammatory activity evaluated by inhibition Carrageenan induced rat paw edema model. Significant reduction of edema () was observed in comparison to the commercial product. Hence oleic acid based vesicles can be used as alternate carrier for topical delivery.

AbstractNovel treatment strategies are urgently required for osteoarthritis (OA). Palmitoylethanolamide (PEA) is a naturally occurring fatty acid amide with analgesic and anti-inflammatory effects. We aimed to examine its effect on OA and elucidate the molecular mechanism of actions in monosodium iodoacetate (MIA)-induced OA Sprague–Dawley rats. The experimental animals were divided into normal control group (injected with saline + treated with phosphate-buffered saline (PBS), NOR), control group (injected with MIA + treated with PBS, CON), 50 or 100 mg/kg body weight (BW)/day PEA-treated group (injected with MIA + treated with 50 or 100 mg of PEA/kg BW/day, PEA50 or PEA100), and positive control group (injected with MIA + treated with 6 mg of diclofenac/kg BW/day, DiC). The changes in blood parameters, body parameters, gene expression of inflammatory mediators and cytokines, knee thickness, and joint tissue were observed. Oral administration of PEA had no adverse effects on the BW, liver, or kidneys. PEA reduced knee joint swelling and cartilage degradation in MIA-induced OA rats. The serum levels of leukotriene B4, nitric oxide, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and prostaglandin E2 considerably reduced in the PEA100 group compared with those in the CON group. In the synovia of knee joints, the mRNA expression of iNOS, 5-Lox, Cox-2, Il-1β, Tnf-α, and Mmp-2, -3, -9, and -13 apparently increased with MIA administration. Meanwhile, Timp-1 mRNA expression apparently decreased in the CON group but increased to the normal level with PEA treatment. Thus, PEA can be an effective therapeutic agent for OA.

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.

BACKGROUND: Cancer growth is influenced by many factors and in general it is an interaction between gene factors and environmental factors, especially the microenvironment that exists around cancer. The inflammatory response plays a decisive role in various stages of cancer growth. AIM: The aim of this study was to determine the anti-inflammatory activity of ethanol extract of Rhaphidophora pinnata leaves. METHODS: R. pinnata leaf extract was obtained by percolation method using 96% ethanol as the solvent at room temperature. Anti-inflammatory activity was determined based on the paw edema method. Thirty male albino mice were treated orally with sodium carboxyl cellulose suspension (as negative control group), R. pinnata leaf extract (35, 70, 140, and 280 mg/kgBW), and diclofenac (as positive control group), 60 min before 0.2 mL 1% carrageenan injection. The paw thickness was measured using plethysmometer before injecting the carrageenan and after 1, 2, 3, 4, 5, and 6 h. RESULTS: The subplantar injection of carrageenan caused a time-dependent paw edema in the mice. Oral administration of R. pinnata leaf extract inhibited paw swelling at 1, 2, 3 4, 5, and 6 h after carrageenan injection. R. pinnata leaf extracts doses of 35, 70, 140, and 280 mg/kgBW gave a percentage inhibition of 56.56%, 56.18%, 62.77%, and 49.30%, respectively. The effective dose of R. pinnata leaf extract as an anti-inflammatory was 140 mg/kgBW. CONCLUSION: Ethanol extract of R. pinnata leaf has anti-inflammatory activity in male albino mice.

Abstract Background: Persisting inflammatory stimuli cause chronic inflammation recognized as the major factor contributing to the development of a number of diseases. One group of drugs used in the treatment of chronic inflammation is the group of non-steroidal anti-inflammatory drugs and, more specifically, the selective COX-2 inhibitors (coxibs). However, most of the coxibs were withdrawn from the market in view of their safety profile. In the present study, 2-[3-Acetyl-5-(4-chlorophenyl)- 2-methyl-pyrrol-1-yl]-4-methylsulfanyl-butyric acid (compound 3e), an Npyrrolylcarboxylic acid derivative structurally related to celecoxib, is evaluated for anti-inflammatory activity after single and multiple (14 days) administration using an animal inflammation model. Aim: To evaluate the anti-inflammatory properties of 2-[3-Acetyl-5-(4-chlorophenyl)-2-methyl-pyrrol-1-yl]-4-methylsulfanyl-butyric acid (compound 3e) after single and multiple (14 days) administration using an animal inflammation model. Materials and methods: Forty Wistar rats were allocated into 5 groups (n=8) treated with saline (controls), diclofenac (25 mg/kg b.w.), compound 3e (10, 20 and 40 mg/kg b.w.) intraperitoneally. The volume of the right hind paw of the animals of all groups is measured prior to treatment and two, three and four hours after administration of carrageenan using a plethysmometer (Ugo Basile, Italy). The percentage of paw edema is calculated using the Trinus formula. Results: In a single administration, compound 3e in doses of 10 and 20 mg/kg b.w. did not inhibit paw edema, while a dose of 40 mg/kg b.w. significantly inhibited carrageenan-induced paw edema at 2 hours in comparison with the control group. After continuous administration, compound 3e in doses of 10, 20 and 40 mg/kg b.w. significantly reduced paw edema at 2, 3, and 4 hours compared to animals treated with saline. Conclusions: Compound 3e shows anti-inflammatory properties similar to those of diclofenac after continuous administration.

Introduction: Guazuma ulmifolia (Sterculiaceae) is commonly used in folk medicine as a single drug remedy to treat various ailments like; skin diseases, headache, wounds, ulcers, asthma, kidney disease and malaria. However, the use of the herb for treatment of pain and inflammation has not been scientifically investigated. Objective: This study of 80% methanolic crude extract of the leaves of Guazuma ulmifolia was evaluated for its analgesic and anti-inflammatory properties using established animal models. Material and methods: Wister albino rats were randomly divided into four groups of six rats per group. The control group was orally given 2 ml/kg (p.o.) of distilled water. The positive control received standard drug (Diclofenac 10 mg//kg, Indomethacin 20 mg/kg). The rest of the groups were treated with 80% methanolic extract of Guazuma ulmifolia at doses of 250 and 500 mg/kg. Animals were then subjected to tests using hot plate and tail-clip for analgesic activity, for anti-inflammatory activity carrageenan-induced paw edema test and histamine-induced paw edema test was used. Result and Discussion: Guazuma ulmifolia extract showed a dose-dependent significant reduction of pain in analgesia models (p<0.001) with 500 mg/kg dose producing the highest reduction. The extract significantly reduced carrageenan-induced inflammation in a dose-independent manner, in which the highest reduction of inflammation was observed at 500 mg/kg. Conclusion: The data collectively indicate that 80% methanolic extract of Guazuma ulmifolia leaves has potential analgesic and anti-inflammatory activities.
