The anti-inflammatory activity of hydroxytriazenes as well as their vanadium complexes has been studied using carrageenan induced hind paw oedema method in albino rats (Wister strain). Hydroxytriazenesviz., 3-hydroxy-1,3-diphenyltriazene(HT-1), 3-hydroxy-3-phenyl-1-(4-sulfonamido)phenyl triazene(HT-2), 3-hydroxy-3-p-chlorophenyl-1-(4-sulfonamido) phenyltriazene(HT-3), 3-hydroxy-3-m-chlorophenyl-1-(4-sulfonamido)phenyltriazene(HT-4)(HT-4) and their respective vanadium complexes C-1, C-2, C-3 and C-4 have been synthesized using standard methods, purified, characterized and used for studying their anti-inflammatory activities. The hind paw oedema was produced by subplanter injection of carrageenan and the paw volume was measured plethysmographically after 0.5, 1, 2, 3 and 5 h. The animals were givenHT-1, HT-2, HT-3andHT-4and also vanadium complexes C-1, C-2, C-3 and C-4 dissolved inDMSO(at dose 5 mg/Kg body weight). Diclofenac sodium (5 mg/kg) was used as a standard drug. The standard drug shows maximum inibition up to 1h as 81.73% which goes on increasing up to 3h (88.94%) but further reduces to 74.93% at the end of 5 h. The test compounds i.e. both ligands as well as their metal complexes show maximum percent inhibition only up to 1h. after which the efficacy reduces. Thus it can be said that both ligands as well as their vanadium complexes show very significant anti-inflammatory activity up to 1h which is comparable to standard drug.

AbstractThe objective of this work was to study the analgesic and anti-inflammatory activity ofHealthy albino rats (150–200 g) and mice (25–50 g) were arranged and divided into five groups. Group 1 received distilled water and served as control, groups 2, 3, 4 were treated with TG stem extract (100, 200, 400 mg/kg) and group 5 received standard drug. For analgesic activity, the radiant heat method and writhing test were used, and for anti-inflammatory activity, the paw oedema model and granuloma pouch method were used. Statistical analysis was done by one-way analysis of variance followed by the t-test.In the radiant heat method, there was a dose-dependent increase in reaction time in TG stem extract (100, 200, 400 mg/kg) and standard drug (buprenorphine). In the writhing test, TG stem extract (200, 400 mg/kg) and aspirin decreased the number of writhes which was significant (p<0.01, p<0.001) as compared to controls. The percentage protection was 8.88%, 15.55%, 22.22% and 35.55% in groups 2, 3, 4 and 5, respectively. In the rat paw oedema test, TG stem extract (200, 400 mg/kg) and aspirin showed 20%, 40% and 54% inhibition of oedema which was statistically significant (p<0.05, p<0.01, p<0.001), respectively, as compared to control at the end of 4 h. In the granuloma pouch method, TG stem extract (100, 200, 400 mg/kg) and aspirin showed 13.33%, 22.22%, 33.33% and 66.66% inhibition of granuloma, respectively, which was significant (p<0.05, p<0.01, p<0.001).TG stem extract possesses significant anti-inflammatory and analgesic activity.

In the present study, the anti-inflammatory activity of aqueous extract of Portulaca oleracea (POE 200, 400 and 600mg/kg) was studied using carrageenan induced paw oedema in albino rats. The mean increase in paw volume was recorded. POE produced significant (p<,0.01) anti-inflammatory activity when compared to the control. The anti-inflammatory action of POEcan be attributed to its flavonoid contents which are known to act through inhibition of prostaglandin biosynthesis. However, the test drug at maximum dose (600mg/kg) was found to be less effective than the standard drug, aspirin (100mg/Kg).

Background: Inflammation is part of the complex biological response of vascular tissues to harmful stimuli. Though there are standard anti-inflammatory drugs like aspirin, diclofenac, etc., these are not free of side effects. This has led to an increase in demand for natural products with anti-inflammatory activity having less side effects. Hence the study was conducted to evaluate the anti-inflammatory activity of ethanolic extract of Ficus racemose (EEFR) in albino rats.Methods: Healthy albino rats of either sex were divided into 4 groups of 6 animals each. Group1-control, group 2-diclofenac sodium 2 mg/kg and group 3 and 4 EEFR (200 and 400 mg/kg respectively), anti-inflammatory activity was evaluated by Carrageenan induced paw oedema: formalin induced-peritonitis and cotton pellet induced granuloma model for in vivo activity and protein denaturation test for in vitro activity.Results: EEFR exhibited significant in vitro (p<0.001) anti-inflammatory effect at the dose of 200 and 400 mg/kg. EEFR produced 61.37% inhibition at the dose of 400 mg/kg and diclofenac (standard drug) produced 62.95% of inhibition after 3 hours of drug treatment in carrageenan induced paw oedema. The exudate volume was decreased in formalin induced peritonitis by EEFR and diclofenac significantly (p<0.001). In cotton pellet induced granuloma EEFR (400 mg/kg) and diclofenac showed decreased formation of granuloma by 28.36% and 28.00% (p<0.001) respectively.Conclusions: EEFR has significant anti-inflammatory activity in both acute and chronic model in a dose dependant manner in comparison with standard drug.

A novel series of 2-(substituted phenoxy)-N-(1,7,7-trimethylbicyclo[2.2.1]heptan-2-yl)acetamide and N-(2-bromocyclohexyl)-2-(substituted phenoxy)acetamide derivatives having cyclohexyl nucleus as common in both types were synthesized and assessed for their anti-inflammatory activity by a carrageenan induced rat paw oedema method, analgesic activity by Eddy?s hot plate method and antipyretic activity by brewer?s yeast induced pyrexia method. All the novel derivatives have been synthesized by the reaction of camphor and similar ketone having cyclohexane nucleus (e.g. 2-bromocyclohexanone) with ammonium carbonate and formic acid resulting in the formation of aromatic amines (1a-b). These amines on further chloroacetylation with chloroacetylchloride give compounds (2a-b). Compounds (2a-b) are converted to 2-(substituted phenoxy)-N-(1,7,7-trimethylbicyclo[2.2.1]heptan-2-yl) acetamide and N-(2-bromocyclohexyl)-2-(substituted phenoxy)acetamide derivatives on treatment with substituted phenol. Among the series 3a-f, 3i, 3k, 3l compounds showed significant anti-inflammatory activity as compared to the standard drug diclofenac sodium and also compound 3a-f, 3h, 3j, 3k exhibit significant analgesic activity as compared to the standard drug. Compounds 3a-f and 3k showed antipyretic activity nearly to the standard drug indomethacin. Compounds 3a-f and 3k possess anti-inflammatory, analgesic and antipyretic activities near to the standard.

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.

The various extracts ofMerremia tridentatewere investigated for its anti-inflammatory and anti-arthritic activities in male albino rats. The anti-inflammatory activity was carried out using carrageenan-induced rat paw oedema model and the anti-arthritic activity was carried out using complete Freund’s adjuvant induced arthritis model. Indomethacin (10 mg/kg bw) was used as a standard drug. The ethanol extract ofM. tridentateexhibited significant dose dependent activity in acute inflammation and the doses of 100 mg/kg bw and 200 mg/kg bw produced 38.3% and 42.8% inhibition respectively after 3 h as compared with that of the standard drug which showed 48.5% inhibition. In arthritis model, the doses of 100 mg/kg bw and 200 mg/kg bw of the ethanol extract produced 49.0% and 51.7% inhibition respectively after 19 days when compared with that of the standard drug (55.5%). Both doses of the ethanol extract ofM. tridentateexhibit significant anti-inflammatory and anti-arthritic activities.

Medicinal herbs have been effectively used for their anti-inflammatory activity, but their exact role has not yet been documented in scientific literature for the management of Osteoarthritis (OA). Since Sida cordifolia L., Piper longum L., Zingiber officinale Rosc., Ricinus communis L., Vitex negundo L. and Tribulus terrestris L. have been widely used in traditional medicine for their anti-inflammatory activity, to evaluate anti-osteoarthritic activity of these herbs, we used a collagenase type II-induced osteoarthritis (CIOA) rat model. Arthritis was induced in wistar rats by intra-articular injection of collagenase type II. Powders of herbs were given orally for 20 days as a suspension in water (270 mg/kg b. wt.). The effects of the treatment in the rats were monitored by physiological parameters like body weight, knee diameter, paw retraction, paw volume, glycosaminoglycan (GAG) release, radiography and histopathology of knee joint. Selected herbs have significantly prevented body weight loss and knee swelling compared to arthritic control (CIOA). All test groups, including indomethacin (standard drug, 3 mg/kg), significantly reduced paw volume compared to CIOA. GAG release in the serum was significantly lowered in herb treated groups compared to indomethacin. The anterior posterior radiographs of S. cordifolia and P. longum treated groups showed a protective effect against OA. Histopathology revealed protection in the structure of the articular cartilage and in chondrocyte pathology as well as reduced clefting. Treatment with herbs has shown chondroid matrix within normal limits. From the results, we observed that S. cordifolia and P. longum possess potent anti-osteoarthritic activity.
