The folkloric use of Clerodendrum volubile P Beauv (Verbenaceae) for treatment of inflammatory conditions in the Southern part of Nigeria has been reported. The anti-inflammatory action of the ethanolic leaf extract on carrageenan-induced rat paw oedema, lipoxygenase and xanthine oxidase inhibitory effects, and membrane stabilizing potential were evaluated. The extract reduced carrageenan-induced rat paw oedema in a dose dependent manner compared to control group. C. volubile inhibited xanthine oxidase activity in a dose - dependent manner; at 0.5 mg/ml it exhibited maximum inhibitory activity of 95.48% while the standard drug, allopurinol exhibited 70 % inhibition. The extract significantly inhibited lipoxygenase activity, with highest activity at 0.4 mg/ml while Quercetin showed maximum inhibition of the enzyme at 0.1 mg/ml. The extract and Acetaminophen exhibited maximum membrane stabilizing activity of 91.85 ± 0.50% and 94.32 ± 0.32% at 2.5 mg/ml respectively. These findings provide justification for the traditional use of C. volubile in inflammatory conditions.

Context. Pleurotus ostreatus (P.o) is a culinary mushroom which is commonly called as “oyster mushroom” belonging to the Basidiomycetous fungi of the order Agaricales and family Pleurotaceae. Objectives. The present study investigates the anti-inflammatory potential of P.o and the underlying mechanisms of activity. Materials and Methods. Anti-inflammatory activity was evaluated using suspensions of freeze-dried and powdered (SFDP) P.o and acetone extract (AE) of P.o in normal and alloxan-induced diabetic rats using the carrageenan-induced rat paw oedema model. The mechanisms by which P.o is mediating the anti-inflammatory activity were studied using in vivo and in vitro assays. Results. At doses of 500–1000 mg/kg, the SFDP of P.o showed long-lasting activity at both early and late phases of carrageenan-induced rat paw oedema. The dose of 750 mg/kg showed the most potent inhibitory activity (92% inhibition) in healthy rats. The AE of P.o showed maximum inhibition of oedema of 87%. P.o exerted protective effects on the inflammatory pathologies in rats with diabetes. The possible mechanisms by which P.o mediates the anti-inflammatory activity were antihistamine activity (52.1%), inhibition of cell migration to the site of inflammation (45.4%), in vitro membrane stabilizing activity (52.6%), and inhibition of nitric oxide (NO) production (91.2%) (P<0.05). Dose-dependent inhibition of NO production was seen with in vitro treatment of rat peritoneal cells with AE of P.o (r = 0.95; P<0.05). Discussion and Conclusion. The promising activity of culinary mushroom P.o against inflammation suggests its potential application as a functional food during inflammatory conditions.

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.

Morinda lucida Benth (Rubiaceae) is a versatile plant used in traditional medicine for the treatment of a variety of ailments and the claims of its efficacy are particularly remarkable in the treatment of infections and immuno-inflammatory disorders. This study evaluates the anti-inflammatory properties of methanolic stem bark extract and fractions of M. lucida and also identifies the phytochemicals responsible for its anti-inflammatory activity. The crude extract was subjected to liquid- liquid partitioning successively with n- hexane, ethylacetate, butanol and water. High performance liquid chromatography (HPLC) of the four fractions and Vacuum Liquid Chromatography fraction (VLC) of the promising fraction was evaluated. The effect of the fractions on egg albumen induced rat paw oedema were also evaluated. Anti-inflammatory activity of the fractions was further screened using xylene induce ear oedema models and human red blood cell membrane stabilization test. Ulcerogenic test on the normal stomach mucosa was also evaluated. The result of the egg albumen induced rat paw oedema showed that the butanol fractions maximally inhibited egg albumen induced effect at 400 mg/kg (70%) and 200mg/kg (67.5%) after 180 minutes compared to the positive control, ibuprofen (20mg/kg) with 100% inhibition after 180 minutes. The result of the xylene induced ear oedema showed that the inhibition produced by 100 µg/ear of the Butanol fraction (BF) was 56.67 % and was greater than inhibition produced by 200 µg/ear of ibuprofen (38.89 %). HPLC analysis of the fractions revealed the following phytocompounds; Cytreo- a-pyrone, Cytosporin- J and Waol A. Ulcerogenic test was negative at the doses of 200 mg/kg and 400 mg/kg of the fractions when compare with the indomethacin (positive control) at dose of 50 mg/kg. Human red blood cell membrane stabilization assay showed that BF-VLC 2 (Dichloromethane: methanol (8:2) VLC of Butanol fraction) exhibited concentration dependent inhibition of heat-induced haemolysis while other extract showed a non- concentration dependent inhibition of haemolysis when compared to the standard, ibuprofen. These findings suggest that the stem bark of M. lucida possess promising anti-inflammatory phytocompounds which justify its use in ethno-medicine.

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.

The aim of the study was to assess the polyphenolic profile, anti-inflammatory and antinociceptive activity of Arctium lappa, a medicinal plant traditionally used in the treatment of gout, hepatitis and other inflammatory disorders. Polyphenolic profile of a hydro-glycero-ethanolic extract from Arctium lappa roots (ALE) was evaluated by HPLC-MS method. Anti-inflammatory effect of the Arctium lappa extract (ALE) was determined by carrageenan-induced rat paw oedema test, while antinociceptive effect was determined by acetic acid induced writhing test in mice and Randall Selitto test in rats. HPLC-MS analysis of the extract showed the presence of chlorogenic acid (158.9 μg/mL) and quercitrin (14.4 μg/mL). The administration of ALE reduced the oedema formation in the carrageenan-induced rat paw oedema test, especially at dose of 500 mg/kg, the results being statistically significant and dose-dependent. Also, ALE showed statistically significant and dose-dependent antinociceptive effects in the acetic acid induced writhing test in mice and Randall Selitto test in rats. The results of the pharmacological experiments suggest that the anti-inflammatory and antinociceptive effects of the Arctium lappa extract (ALE) may be related to the ability of polyphenols such as chlorogenic acid to inhibit the synthesis and release of some pro-inflammatory mediators. Our experimental data justify the traditional use of this plant in the management of some inflammatory disease.

Rat Paw Oedema

Since ancient times in India several medicinal plants are in use for clinical practices. Inflammation is a process through which the body's white blood cells and the things they make protect body from infection from outside invaders, such as bacteria and viruses. Currently many of the plant’s species have been reported effective as an Anti-inflammatory, but only a few of them have been investigated. Currently many drugs are available to control the inflammation but has several adverse effects. The plant Sida Cordata was reported to have several activities such as Antioxidant, Analgesic, Antidepressant, Antihyperglycemic, Hepatoprotective Antibacterial, Antitumor, Antifungal, Antiulcer, Antitussive, Anti-inflammatory, Anti-malarial, in ayurvedic system of medicine. This study was undertaken to investigate the anti-inflammatory activity of Methanolic extract of Sida Cordata. The methanolic extract of Sida Cordata used for treatment of Carrageenan-induced Rat paw Oedema model with the predefined dose as reported. The experimental groups with higher dose of methanolic extract (200 mg/kg) exhibited a significant anti-inflammatory effect after 2 hr. (p<0.01); based on the observation, the activity was favorable, which is nearly equal to that of the standard drug Indomethacin (10 mg/kg). The methanol extract (200 mg/kg) shows the maximum percentage of inhibition of inflammation 27.06 %. The standard drug indomethacin shows 33 % inhibition.

Background: Lichens which are betide to mangroves are termed as Manglicolous Lichens (ML). As these ML are habituated under stress conditions, they are screened for unique metabolites and biological activities. Objective: The study aimed to establish the chemical and biological profile of ML, Graphis ajarekarii. Methods: The Ethyl Acetate Extract of G. ajarekarii (EAE) was subjected to chromatographic techniques and the obtained isolates were characterized by spectroscopic analysis. The hydroalcoholic extract of G. ajarekarii (AE), EAE, isolates and Hydroalcoholic Extract of host (HE) were evaluated for fibrinolytic (fibrin clot method), in vitro (protein denaturation method) and in vivo (formalin-induced rat paw oedema assay), anti-inflammatory and cytotoxicity (MTT assay) activities. Results: Chemical investigation of the EAE led to the isolation of two known compounds namely atranorin (1) and ribenone (2), which were confirmed by spectral data. The AE and EAE gradually lysed the fibrin clot with 94.54 and 65.07%, respectively, at 24 h. The AE inhibited protein denaturation of about 88.06%, while the standard (Indomethacin) with 93.62%. Similarly, the in vivo antiinflammatory analysis of AE (200 mg/mL) showed potent reduction of rat paw oedema than the standard, whereas EAE and 1 depicted moderate depletion. In addition, the AE revealed prominence inhibition on MCF-7, DU145 and K-562 with IC50 values of 69.5, 42.5 and 38 µg/mL, respectively, whereas the HE exhibited mild inhibitory profile against fibrin clot, inflammation and cancer. Conclusion: From the results, it can be concluded that the G. ajarekarii has an aptitude to act against coagulation, inflammation and cancer cells.

Alchornea cordifolia (Schum and Thonn) Muell. Arg. (Euphorbiaceae) is a traditional medicinal plant widely distributed in West Africa including Nigeria.The plant has been used for ethnomedicinal purposes against wounds, ulcers, and sores. The decoction of the leaves has been reported to provide remedies for bronchial problems, rheumatic pain and cough. From the dichloromethane and ethyl acetate soluble parts of the Methanol leaf extract, two compounds namely Lup-20(29)-en-3c-ol (lupenol) and Methyl 3, 4,5-trihydroxy benzoate (Methyl gallate) were isolated and their structures elucidated. Anti-inflammatory and analgesic properties of the compounds on carrageenan-induced paw oedema and formalin-induced pain in rats showed that compound 2 significantly (P<0.05) inhibit rat paw oedema compared to the standard drugs (Piroxicam and Morphine) used, while on formalin-induced pain in rats, the same trend was observed and were both comparable to Piroxicam and morphine, the standard anti-inflammatory and analgesic agents used, respectively. Compound 1 did not show any significant anti-inflammatory activity compared to control, likewise compound 2. Thus, compound 2, Methyl trihydroxy benzoate, might be responsible for the anti-inflammatory and analgesic properties of this plant.Keywords: Alchornea cordifolia, Anti-inflammatory, Analgesic, Methyl Trihydroxy Benzoate

The current study was planned to evaluate comparative anti-inflammatory, analgesic and anti-pyretic activities of two newly synthesized organo-antimony (v) ferrocenyl benzoate derivatives with piroxicam. Anti-microbial activity of these compounds was also screened against two microorganisms. Analgesic effect of test compounds was evaluated by formalin-induced paw licking test in mice. The test compounds at 50 and 100 mg/kg b.w. doses exhibited significant (p<0.001) reduction of paw licking in treated mice comparable with standard drug piroxicam. Anti-inflammatory activity was assessed against carrageenan-induced paw oedema. The compound A produced anti-inflammatory effects comparable with standard piroxicam in dose dependent manner whereas compound B showed better effects than piroxicam at dose of 100 mg/kg body weight. To investigate anti-pyretic activity, fever was induced by administration of Brewer’s yeast in mice. Compound A showed highly significant inhibition of pyrexia (p<0.001) comparable to piroxicam after 3 hours while compound B (50 and 100 mg/kg) produced relatively lower anti-pyretic effect than standard drug. Antibacterial activity determined by disc diffusion method showed that compound B was relatively more effective than compound A against Staphylococcus aureus and Klebsiella pneumoniae. It is conceivable that both the tested compounds possessed anti-inflammatory, analgesic, anti-pyretic and anti-microbial effects even after the structural modification of parent compound.Bangladesh Pharmaceutical Journal 19(1): 15-24, 2016
