Warionia saharae Benth & Coss (W.s) (Asteraceae) is a monospecific genus endemic to Algeria and Morocco. Its leaves are used in their traditional medicine, such as gastrointestinal and inflammatory diseases; for instance, rheumatoid arthritis treatment. In this work, our team investigated the anti-inflammatory and analgesic effects of essential oil extracted from the dried upper parts of Warionia saharae based on different standard experimental test models. The analgesic activity was assessed by central and peripheral models, such as “hot plate” and “writhing” tests on Swiss albino mice. The hot plate test used latency measurements to assess acute cutaneous pain sensitivity, as a result; the latency of the hind-paw pain response was by licking and either shaking or jumping, those occurrences were recorded. Writhing test as a chemical method used to induce pain of peripheral origin in mice by injecting acetic acid intraperitoneally (IP). This results in characteristic stretching behavior of the animals (cramps and contortions). The evaluation of the analgesic activity, shows that the essential oil of this plant induces a decrease in the number of abdominal cramps in the contortion test and a maximum inhibition of pain. As for the anti-inflammatory effect, it was studied by the “paw edema” test, a phlogogenic agent (formaldehyde) was used to stimulate inflammation in the paws of mice. Anti-inflammatory properties can be observed by inhibiting this edema compared to the standard drug Diclofenac. In conclusion, Warionia saharae essential oil (75 mg/kg) showed a strong anti-inflammatory and analgesic activities which supports the conventional use of this plant in traditional medicine.

This study was aimed to design novel diclofenac hydrazones having anti-inflammatory and analgesic activity with gastric sparing effect. A new series of 2-[2-(2,6-dichloroanilino)phenyl]-N’-[(substituted phenyl) methylidene] acetohydrazide derivatives (1−14) were synthesized and evaluated for their anti-inflammatory, analgesic, and ulcerogenic activity. The compounds were identified and confirmed by elemental analysis and spectral data. During anti-inflammatory activity by carrageenan-induced paw edema method, compounds (2, 3, 7, 8, 11, and 13) were found to be most promising. Compounds 3, 8, and 13 have been found to have significant analgesic activity compared to the reference drug diclofenac in analgesic activity by both the hot plate method and acetic acid-induced writhing method. The compounds which presented highly significant anti-inflammatory and analgesic activity were further tested for their ulcerogenic activity. Compounds 3 and 8 showed maximum ulcerogenic reduction activities. Compound 8 was found to have LD50 of 168 mg/kg. Compound 8 with 3,5-dimethoxy-4-hydroxyphenyl substitution was found to be the most promising anti-inflammatory and analgesic agent with gastric sparing activity. Molecular docking of compounds was performed for COX−1/COX−2 binding site. Lead compound 8 showed better binding affinities of −9.4 kJ/mol with both COX-1 and COX-2 as compared to the standard drug, diclofenac with binding affinities of −6.6 kJ/mol and −8.1 kJ/mol for COX−1 and COX−2, respectively.

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.

Analgesic, anti-inflammatory and anti-pyretic activities of n-hexane and aqueous ethanolic extracts of Malva neglecta in Swiss albino mice was evaluated. For each activity, the mice were divided into 4 groups: Group 1 served as control, Groups 2 and 3 were given n-hexane and aqueous ethanol extracts, respectively whereas Group 4 was treated with the standard drug. Analgesic activity was evaluated against acetic acid induced writhing, Eddy's hot plate method, and Formalin induced paw licking. Anti-inflammatory activity was evaluated by carrageenan-induced paw edema. The extracts were also examined for their anti-pyretic activities against yeast-induced pyrexia. Results showed that the n-hexane (p < 0.05) and aqueous ethanolic (p < 0.005) extracts of M. neglecta exhibited analgesic activity by reducing acetic acid-induced writhing, mean reaction time on hot plate model and formalin-induced paw licking in mice as compared to the control. The n-hexane extract (p < 0.05) as well as aqueous ethanolic (p < 0.005) extracts produced significant antiinflammatory activity as compared to the control. Both the n-hexane and aqueous ethanolic extracts revealed significant antipyretic activity (p < 0.005 and p < 0.05, respectively) in mice model. The results of the present study demonstrated that the n-hexane and aqueous ethanol extracts of M. neglecta possess analgesic, antiinflammatory and anti-pyretic activities. Bangladesh J.

Celery (Apium graveolensL.) belongs to the Apiaceae family. It is a genus of an annual or biannual herb.A. graveolensis used in Algeria as a medicinal plant for the treatment of many diseases. This study was carried out to assess and confirm the in vivo anti-inflammatory and analgesic effect of hydroalcoholic extract fromA. graveolensleaves. Wistar albino rats of both sexes, with different ages 2–3 months weighing between 160 and 250 g and Swiss albinosmice weighing 22–27 g were used for this study. The antiinflammatory activity was estimated by measuring the oedema induced by Carrageenan; the analgesic activity was performed by the acetic acid–induced writhing test and formalin-induced paw licking. The administration of hydroalcoholic extract at doses of 200, 300 and 500 mg/kg body weight significantly reduced the increase of the paw volume with an inhibition percentage of 80.17%, 86.50% and 89.66%, respectively; all doses showed a strong significant effect (p< 0.001). These results were similar to those obtained with piroxicam 78.93% and indometacine 76.13%. Although the same doses showed a high significant effect (p< 0.01) compared to the control group, the extract at a dose of 500 mg/kg registered higher levels of analgesic activity (17 ± 2.36) writhing (75.53% inhibition) than the standard drug paracetamol (30.5 ± 3.61) writhing; in the two tests, acetic acid induced writhing and formalin induced paw licking. The study of hydroalcoholic extract in vitro showed a high antioxidant capacity by inhibition of 2,2-diphenyl-1-picrylhydrazyl radical (IC50= 1.29 mg/ml). In conclusion,A. graveolensis an interesting plant and the hydroalcoholic leaves extracts could be used scientifically in the treatment of acute inflammation and the peripheral analgesic activity.

Background: Levocetirizine, the R-enantiomer of Cetirizine has pharmacokinetically and pharmacodynamically favourable characteristics, with rapid onset of action, high bioavailability, high affinity for and occupancy of the H1-receptor, limited distribution, minimal hepatic metabolism together with minimal side effects. Non-steroidal anti-inflammatory drugs (NSAIDs) have been used for many years for analgesic, anti-inflammatory, and more recently in the case of aspirin, antithrombotic purposes. Because of the significant side effect profiles of steroidal and NSAID medications, there is a greater interest in newer compounds such as antihistaminic drugs. This article will consider the potential or otherwise of the reported analgesic and anti-inflammatory effects of levocetirizine to enhance its effectiveness in the treatment of allergic disease with pain.Methods: Albino Wistar rats of either sex weighing 150-250 grams were used. For both Analgesic activity and Anti-inflammatory activity, 4 groups consisting of 6 animals per group were used. Group I: Control: 1% Gum acacia. 2ml/kg, Group II: Standard drug: Diclofenac sodium 4.5mg/kg; Group III: Test Drug 1: Levocetirizine 1mg/kg; Group IV: Test Drugs 2: Levocetirizine 1mg/kg+Diclofenac sodium 4.5mg/kg. Drugs were administered orally. For analgesic activity, Tail clip method and Hot plate method was used. For acute anti-inflammatory activity Carrageenan induced rat paw oedema method was used.Results: Levocetirizine, is found to have significant analgesic activity in rats (1 mg/kg dose) alone and in combination with Diclofenac Sodium in Haffner’s Tail Clip method and Eddy’s Hot Plate Method. Levocetirizine also has got prominent anti-inflammatory activity in acute models evidenced by percentage inhibition of acute rat paw oedema.Conclusions: Levocetirizine possess analgesic and acute anti-inflammatory activity alone and in combination with Diclofenac sodium.

Objective:To study the analgesic and acute anti-inflammatory effect of the ethanolic extract of the leaves of Paederia foetida (EEPF) on experimental animal models. Materials and Methods: Fresh leaves were collected, air-dried, powdered, and percolated in 95% ethanol. Acute toxicity test was done according to OECD guidelines. Healthy albino rats (150-200 gm) of either sex were taken and divided into five groups with six animals in each group for central analgesic activity by tail flick method. Peripheral analgesic activity by 1% glacial acetic acid induced writhing test by taking albino mice (20-30 gm) of either sex which were divided into three groups with six animals in each. EEPF was used in a dose of 500 mg/kg bodyweight subcutaneously for tail-flick method and orally for writhing test. In tail-flick method the basal reaction time was taken and a cut-off period of 10 sec was observed. Reaction time were recorded at predrug, 15, 30, 60, 90, 120, 150 and 180 minutes after administration of drug . The standard drug used for central analgesic activity was pethidine 5 mg/kg bw, naloxone 1mg/kg as antagonist and naloxone 1mg/kg bw with 500mg/kg bw of EEPF to study the central mechanism of action. The standard drug used for peripheral analgesic activity was aspirin 100mg/kg bw orally. A control group was maintained in all the models. For anti-inflammatory study, three groups of animals of either sex (n = 6), weighing 150-200g of the species Rattus norvegicus were taken for the study. Group A was taken as control (Normal salie, 10 mL/kg body weight), Group B as test group (EEPF 500 mg/kg body weight), and Group C as standard (Aspirin 100 mg/kg body weight). The animals were studied for acute inflammation by Carrageenan-induced rat paw edema. Statistical analysis  was done by one-way analysis of variance followed by multiple comparison tests.Results: EEPF significantly increased the reaction time in tail-flick method (p<0.05) whereas the combination of naloxone and EEPF decreased the reaction time indicating that naloxone inhibits the analgesic effect of EEPF. In 1% glacial acetic acid induced writhing EEPF reduced writhing significantly In acute inflammation, there was significant inhibition of paw edema in Groups B, C in comparison with Group A (P < 0.05). Conclusion:The ethanolic extract of Paederia foetida has significant analgesic and anti-inflammatory activity.

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.
