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: This study aims to perform phytochemical screening and investigate anti-inflammatory activity of extract from aerial part of the plant Plantago major L.Methods: Preliminary phytochemical screening of plant extract was carried out using standard qualitative procedures and anti-inflammatory activity was evaluated using carrageenan-induced paw edema model in male Wistar albino rats using plethysmometer. Diclofenac sodium (10 mg/kg, b.w.) was used as standard drug.Results: Preliminary phytochemical screening of the different extracts revealed that they were rich in secondary metabolite compounds such as carbohydrates, tannins, steroids, flavonoids, terpenoids, glycosides, fats and oils, alkaloids, phenolic compounds, and iridoid glycosides. The anti-inflammatory activity was evaluated using carrageenan-induced paw edema models in Wistar albino rats. The anti-inflammatory activity of methanolic extract (ME) was found to be dose dependent in carrageenan-induced paw edema model. The ME has shown significant (p<0.05) inhibition of paw edema, 61.11% and 55.55% on 4th hr at the doses of 900 and 600 mg/kg, respectively.Conclusion: The results of the present study demonstrate that ME of the aerial parts of the plant possess significant (p<0.05) anti-inflammatory potential.

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.

Abstract Viscum album L. has been used in the indigenous systems of medicine for treatment of headache and some inflammatory diseases. In order to evaluate this information, antinociceptive and anti-inflammatory activities of the five flavonoids (5,7-dimethoxy naringenin or 4′,6′- dimethoxy chalcononaringenin) derivatives, isolated from the ethyl acetate fraction of the extract from V. album ssp. album, were investigated, namely 5,7-dimethoxy-flavanone-4′-O- β-ᴅ-glucopyranoside (1), 2′-hydroxy-4′,6′-dimethoxy-chalcone-4-O-β-ᴅ-glucopyranoside (2), 5,7-dimethoxy-flavanone-4′-O-[2″-O-(5‴-O-trans-cinnamoyl)-β-ᴅ-apiofuranosyl]-β-ᴅ-glucopyranoside (3), 2′-hydroxy-4′,6′-dimethoxy-chalcone-4-O-[2″-O-(5‴-O-trans-cinnamoyl)-β-ᴅ-apiofuranosyl]- β-ᴅ-glucopyranoside (4), 5,7-dimethoxy-flavanone-4′-O-[β-d-apiofuranosyl- (152)]-β-ᴅ-glucopyranoside (5). For the antinociceptive activity assessment the p-benzoquinone- induced writhing test and for the anti-inflammatory activity the carrageenan-induced hind paw edema model in mice were used. The ethyl acetate fraction in a dose of 250 mg/kg as well as compounds 2 and 5 in a 30 mg/kg dose were shown to possess remarkable antinociceptive and anti-inflammatory activities per os without inducing any apparent acute toxicity as well as gastric damage

The anti-inflamrnatory properties of Loasa specic¡sa and Loasa triphylla (Loasaceae), Urtica leptuphylla and Urera baccifera (Urticaceae), and Chaptalia nutans (Astemceae) were studied using the carregeenan induced mt paw edema model. Aqueous extmcts of each plant were made according to the ethnoboranical use. The hippocratic assay was made with female mts; the dose used was 500 mglkg i.p. andthe control group received 0.5 mi of n.s.s .. A11 the lmimals treated showed hipothermia, and those treated with the extmcts of Chaptalia nutans, Urera baccifera and Urtica lept/lPhylla showed an increased colinergic activity. Acute toxicities of !he aqueous extmcts were studied in mice an tbe mean lethal doses ranged between 1.0226 and 1.2022 glkg. The extracts of Urera baccifera, Chaptalia nutans, Loasa speciosa and Loasa triphylla (500 mglkg i.p.) showed an antiinflarnmatory activity compamble with that of indomethacin. The extracts of U. baccifera and C. nutans, which showed the gI"tatest anti-inflamrtJatory activity, did not show it when used orally (500 mg/k:g p.o.).
