Plants provide an alternative source to manage different human disorders due to various metabolites. The aim of this study is to investigate the phytochemical constituents of the methanolic extracts ofEuphorbia retusaand to evaluate their antioxidant, anti-inflammatory, and analgesic activities. The phytochemical results obtained by HPLC and by chemical assay reactions have revealed the richness of the methanolic extract ofE. retusain active compounds, in particular polyphenols, flavonoids, and tannins. The methanolic extract shows significant antioxidant activitiesin vitro, in the DPPH and the FRAP assays. The antinociceptive activity was evaluated using acetic acid and hot-plate models of pain in mice. The anti-inflammatory activity was evaluated by carrageenan-induced paw edema. Oral pretreatment with the methanolic extract ofE. retusa(200 mg/kg) exhibited a significant inhibition of pain induced either by acetic acid or by the heating plate and in a manner comparable to the standard drug paracetamol.E. retusasignificantly reduced paw edema starting from the 3rd hour after carrageenan administration by increasing the activity of antioxidant enzymes (SOD, CAT, and GPx) in liver and paw tissues and decreasing the levels of MDA. These results may confirm the interesting potential of this plant as a treatment of various inflammatory and pain diseases.

 Objectives: A persistent and chronic inflammation may act as an underlying definition for many of the long-term illness such as diabetic foot ulcer, Alzheimer’s disease and rheumatoid arthritis. Folklore medicinal plants provide immense health benefits with new remedies. Active compounds from plants containing alkaloids and phenolic compounds (flavonoids and tannins) possess antioxidant and anti-inflammatory activity. The leaves of Adhatoda vasica are most known for its effectiveness in treating respiratory diseases such as asthma, chronic bronchitis, and other respiratory conditions. In this report, we investigated the possible action of A. vasica against inflammation.Methods: Solvents with varying polarity (Hexane, dichloromethane, ethyl acetate, and methanol) were used for the sequential extraction of leaves of A. vasica Linn (Family: Acanthaceae). The anti‐inflammatory activity was assessed using simple in vitro methods. Phenols, flavonoids, phytosterols, saponins, alkaloids, and tannins were analyzed qualitatively using standard protocols. Anti‐inflammatory activity was evaluated using albumin denaturation assay, membrane stabilization assay and proteinase inhibitory activity. Aspirin (diclofenac) was used as a standard drug for the study of anti-inflammatory activity.Results: Our results substantiated that methanolic extract of A. vasica gave a maximum yield of 12.5% and apparently all bioactive phytochemical constituents were at a higher concentration in the methanolic extract. Methanolic extract of A. vasica showed a significant inhibition of the heat-induced albumin denaturation, red blood cells membrane stabilization, and proteinase inhibitory effects with 86±1.46, 88±1.24, and 96±0.93% for 1000 μg/ml, respectively.Conclusion: The above results delineate that the bioactive components were extracted using high polar solvent are mostly flavonoids and related polyphenols. These compounds may be the active constituents to render the anti-inflammatory activity to A. vasica.

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.

Objective: Dietary curcumin and capsaicin are well known for their health beneficial potencies. The current study was done to assess the anti-inflammatory activity of curcumin, capsaicin and their combination by employing in vitro and in vivo models.Methods: We investigated the protective effect of curcumin, capsaicin and their combination using in vitro heat induced human red blood cell (HRBC) membrane stabilisation, in vivo 3% agar induced leukocyte mobilisation and acetic acid induced vascular permeability assay.Results: Curcumin, capsaicin and their combination exhibited concentration dependent protective effect against heat-induced HRBC membrane destabilisation, while combined curcumin and capsaicin restored 87.0±0.64 % membrane stability and it is found to be better than curcumin, capsaicin and diclofenac sodium (75.0±0.25. 72±0.9 and 80.0±0.31 %) protective effect. In agar suspension induced leukocyte mobilization assay, the combined curcumin and capsaicin had shown 39.5±1.58 % of inhibition compared to individual curcumin and capsaicin, which showed moderate inhibition of 16.0±3.14 and 21.6±2.17 % respectively. Besides, the combined curcumin and capsaicin had shown highly significant inhibition of acetic acid-induced vascular permeability in rats (62.0±3.14 %), whereas individual curcumin and capsaicin showed moderate inhibition of vascular permeability with 36.0±2.41 and 43.0±1.92 % respectively.Conclusion: This study demonstrates the significant anti-inflammatory property of combined curcumin and capsaicin at half of the individual concentration of curcumin and capsaicin.

Polyphenolic enriched extracts from two species of Cyperus, Cyperus glomeratus and Cyperus thunbergii, possess mammalian arginase inhibitory capacities, with the percentage inhibition ranging from 80% to 95% at 100 µg/mL and 40% to 64% at 10 µg/mL. Phytochemical investigation of these species led to the isolation and identification of two new natural stilbene oligomers named thunbergin A-B (1–2), together with three other stilbenes, trans-resveratrol (3), trans-scirpusin A (4), trans-cyperusphenol A (6), and two flavonoids, aureusidin (5) and luteolin (7), which were isolated for the first time from C.thunbergii and C. glomeratus. Structures were established on the basis of the spectroscopic data from MS and NMR experiments. The arginase inhibitory activity of compounds 1–7 was evaluated through an in vitro arginase inhibitory assay using purified liver bovine arginase. As a result, five compounds (1, 4–7) showed significant inhibition of arginase, with IC50 values between 17.6 and 60.6 µM, in the range of those of the natural arginase inhibitor piceatannol (12.6 µM). In addition, methanolic extract from Cyperus thunbergii exhibited an endothelium and NO-dependent vasorelaxant effect on thoracic aortic rings from rats and improved endothelial dysfunction in an adjuvant-induced arthritis rat model.

Cyrtocarpa procera is a plant used in traditional Mexican medicine to treat different gastrointestinal problems. Here, we investigated the effects of a C. procera methanolic extract in DSS-induced colitis mice. Ulcerative colitis (UC) was induced by administering 4% DSS in drinking water to female BALB/c mice. Compared to untreated mice with UC, the treatment group receiving the C. procera extract presented less severe UC symptoms of diarrhea, bleeding, and weight loss. Additionally, colon shortening was significantly reduced, and at the microscopic level, only minor damage was observed. Levels of proinflammatory cytokines such as TNF-α, IL-1β, and IFNγ in serum as well as the MPO activity in the colon were significantly reduced in the C. procera methanolic extract-treated group. Moreover, the extract of C. procera reduced oxidative stress during UC, preventing the deterioration of the activity of antioxidant enzymes such as SOD, CAT, and GPx. Additionally, the extract decreased lipid peroxidation damage and its final products, such as malondialdehyde (MDA). In agreement with this, in vitro assays with the C. procera extract displayed good antioxidant capacity, probably due to the presence of polyphenolic compounds, in particular the flavonoids that were identified, such as chrysin, naringenin, kaempferol, and catechin, which have been reported to have anti-inflammatory and antioxidant activities. Therefore, the improvement of UC by the C. procera methanolic extract may be related to the action mechanisms of these compounds.

The compound (E)-2-cyano-3-(1H-indol-3-yl)-N-phenylacrylamide (ICMD-01) was designed and developed based on the structures of clinically relevant drugs indomethacin and paracetamol through the molecular hybridization strategy. This derivative was obtained by an amidation reaction between substituted anilines and ethyl 2-cyanoacetate followed by a Knoevenagel-type condensation reaction with indole aldehyde that resulted in both a viable synthesis and satisfactory yield. In order to assess the immunomodulatory and anti-inflammatory activity, in vitro assays were performed in J774 macrophages, and significant inhibitions (p < 0.05) of the production of nitrite and the production of cytokines (IL-1β and TNFα) in noncytotoxic concentrations were observed. The anti-inflammatory effect was also studied via CFA-induced paw edema in vivo tests and zymosan-induced peritonitis. In the paw edema assay, ICMD01 (50 mg kg−1) showed satisfactory activity, as did the group treated with dexamethasone, reducing edema in 2–6 h. In addition, there was no significant inhibition of PGE2, IL-1β or TNFα in vivo. Moreover, in the peritonitis assay that assesses leukocyte migration, ICMD-01 exhibited promising results. Therefore, these preliminary studies demonstrate this compound to be a strong candidate for an anti-inflammatory drug together with an improved gastrointestinal safety profile when compared to the conventional anti-inflammatory drugs.

Objective: The aim of the present study was to evaluate anti-inflammatory activity of methanolic extract of Terminalia coriacea. Materials and Methods: A methanolic extract of T. coriacea leaves was studied in albino Wistar rats with carrageenan-induced paw edema, an acute model, and cotton pellet-induced granuloma, a chronic model, at 3 oral test doses (125, 250, and 500 mg/kg). Aspirin 100 mg/kg was used as a positive control. Paw volume and wet and dry weights of cotton pellets were determined. The data were analyzed by one-way ANOVA followed by Dunnett’s multiple comparison test. Results: The test extract at doses of 125 and 250 mg/kg decreased paw volume and wet and dry weights of cotton pellets. The highest test dose (500 mg/kg) displayed a response comparable to that of the standard drug (p < 0.01) on paw volume. The extract produced similar (p < 0.05) decrease in wet weight of the cotton pellet at 125 and 250 mg/kg, whereas the effect of 500 mg/kg of the extract was comparable to that of aspirin 100 mg/kg (p < 0.01). The extract of T. coriacea at 500 mg/kg induced the most significant (p < 0.01) effect on wet weight of granulomatous tissue. Conclusion: The methanolic extract of T. coriacea leaves successfully decreased paw edema as well as dry and wet weights of granulomatous tissue in both acute and chronic inflammatory models thus confirming the anti- edematogenic, antitransudative, and antiproliferative properties of T. coriacea.

Objective: Objective of the study was to synthesize and evaluate a series of novel compounds, ethyl 2-(2-cyano-3-(substituted phenyl)acrylamido)- 4,5-dimethylthiophene-3-carboxylates, for in vitro antioxidant and in vivo anti-inflammatory activities.Methods: Ethyl 2-(2-cyano-3-(substituted phenyl)acrylamido)-4,5-dimethylthiophene-3-carboxylates were synthesized by knoevenagel condensation of active methylene group of ethyl 2-(2-cyanoacetamido)-4,5-dimethylthiophene-3-carboxylate with substituted benzaldehydes. The synthesized compounds were evaluated for their in vitro antioxidant properties in three different models, viz., reduction of 1,1-diphenyl-2-pycrylhydrazyl free radical, scavenging of nitric oxide free radical, and ferric ion-induced lipid peroxidation using rat brain homogenate. Few selected compounds with good antioxidant properties were pharmacologically evaluated for anti-inflammatory activity by carrageenan-induced rat paw edema model.Results: Clean and efficient synthetic procedure was used for the preparation of series of compounds. The structures of synthesized compounds were confirmed by infrared, 1H nuclear magnetic resonance and mass spectra. The antioxidant activity data revealed that the compounds of ethyl 2-(2-cyano-3-(substituted phenyl)acrylamido)-4,5-dimethylthiophene-3-carboxylate containing phenolic substitution showed greater antioxidant activity. Hence, the active compounds were evaluated for anti-inflammatory activity and found to possess good activity. The percentage inhibition of rat paw edema obtained for the evaluated compounds was in the range of 70.2-83.1, comparable to the standard drug diclofenac (85.0%).Conclusion: The use of inexpensive, eco-friendly and readily available reagents, easy work-up and high purity of products makes the procedure a convenient and robust method for the synthesis of title compounds. The compounds of ethyl 2-(2-cyano-3-(substituted phenyl)acrylamido)-4,5- dimethylthiophene-3-carboxylate containing phenolic substitution showed greater antioxidant and anti-inflammatory activities.
