Antiinflammatory, Analgesic and Antipyretic Activities of Mimusops elengi Linn

In the present study, 70% ethanol extract of Mimusops elengi Linn. bark was assessed for antiinflammatory, analgesic and antipyretic activities in animals. The antiinflammatory activity of ethanol extract of Mimusops elengi (200 mg/kg, p.o) was evaluated using carrageenan-induced paw edema and cotton pellet-induced granuloma models. Analgesic effect was evaluated using acetic acid-induced writhing and Eddy's hot plate models and antipyretic activity was assessed by Brewer's yeast-induced pyrexia in rats. The ethanol extract of Mimusops elengi (200 mg/kg, p.o) significantly inhibited the carrageenan-induced paw oedema at 3rd and 4th h and in cotton pellet model it reduced the transudative weight and little extent of granuloma weight. In analgesic models the ethanol extract of Mimusops elengi decreases the acetic acid-induced writhing and it also reduces the rectal temperature in Brewer's yeast induced pyrexia. However, Mimusops elengi did not increase the latency time in the hot plate test. These results show that ethanol extract of Mimusops elengi has an antiinflammatory, analgesic and antipyretic activity.

Evaluation of the anti-inflammatory and analgesic properties of the extract of Russelia equisetiformis (Schlecht &; Cham) Scrophulariacae

A methanolic extract of Russelia equisetiformis whole plant was studied for anti-inflammatory and analgesic activities in rats and mice using carrageenan-induced rat paw oedema, aceticacid-induced writhing and tail-flick test. The extract, at 10, 20 and 40 mg/kg, significantly (P <0.05) inhibited carrageenan-induced oedema in rats. Abdominal constriction induced by acetic acid was also inhibited by the extract, within the same dose range. The extract at the same dose also prolonged the latency period in the tail-flick response test, which was reverted by naloxone. The results suggested that the extract possesses potential anti-inflammatory and analgesic properties.     

Analgesic and anti-inflammatory activity of Argyreia speciosa root

Objective:

To study analgesic and anti-inflammatory activities of a methanolic extract (ME) of Argyreia speciosa (AS) root powder.

Materials and Methods:

The study was carried out using male albino mice (20-25 gm) and male wistar rats (100-150gm). The ME was prepared using soxhlet extraction process. The effect of ME of A. speciosa was investigated for analgesic activity using acetic acid-induced abdominal constriction, tail immersion method and hot plate method. The anti-inflammatory activity of ME of AS roots was studied using carrageenan-induced rat paw edema.

Result:

The ME of A. speciosa root was used in pain and inflammation models. The analgesic activity of AS at the dose of (30,100, and 300 mg/kg p.o) showed significant (P<0.01) decrease in acetic acid-induced writhing, whereas ME of A. speciosa at the dose of (100, 300 mg/kg p.o) showed significant (P<0.01) increase in latency to tail flick in tail immersion method and elevated mean basal reaction time in hot plate method. The ME of the A. speciosa at doses (30, 100, and 300mg/kg) showed significant (P < 0.01) inhibition of carrageenan induced hind paw edema in rats.

Conclusion:

The ME of A. speciosa showed significant analgesic and anti-inflammatory activity in mice and rat.     

Synthesis, analgesic and anti inflammatory activities of some new fenamate analogues

A series of fenamate quinazolinyl analogues, viz acids 6a-d, esters 6e-h, carbohydrazides 7a-d, arylidenes 8a-d, oxadiazol-2-ones 13a-d and oxadiazol-2-thiones 14a-d, have been prepared and screened for their analgesic (acetic acid-induced writhing), anti-inflammatory (carrageenan-induced rat paw edema) activities as well as their ulcerogenic effects. All the final compounds except 7a-d and 8a-d showed good dual activities. Compounds 6a, 6b, 6e, 6f, 13a and 14a showed activities comparable to that of mefenamic acid (CAS 61-68-7) in the acetic acid-induced writhing model as well as in the carrageenan-induced rat paw edema test at a dose level of 100 mg/ kg.Compounds 6a and 6b were highly ulcerogenic, while compounds 6e, 6f, 13a and 14a exhibited the lowest ulcerogenic effects.     

Analgesic and anti-inflammatory activity of amifostine, DRDE-07, and their analogs, in mice

Objectives:

To find out the analgesic and anti-inflammatory activity, if any, of Amifostine [S-2(3 amino propyl amino) ethyl phosphorothioate], DRDE-07 [S-2(3 amino ethyl amino) ethyl phenyl sulphide] and their analogs DRDE-30 and DRDE-35, the probable prophylactic agent for sulphur mustard (SM).

Materials and Methods:

In order to find out the analgesic activities of the compounds two methods were employed, namely, acetic acid-induced writhing test and formalin-induced paw licking. The persistent pain model of formalin-induced hind paw licking was carried out to test the effect of the compounds on neurogenic pain or early phase (0 to 5 minutes) and on the peripheral pain or the late phase (15 to 30 minutes). To test the effect of the compound in acute inflammation, carrageenan-induced hind paw edema was carried out. This model of inflammation involves a variety of mediators of inflammation.

Results:

DRDE-07 (81.7%) and DRDE-30 (79.4%) showed significant reduction in the acetic acid-induced writhing test. DRDE-07 (93.1%), DRDE-30 (82%), and DRDE-35 (61.3%) showed significant reduction in the second or late phase of formalin-induced paw licking. All the analogs (more than 60%) including amifostine (43.9%) showed significant reduction of paw edema in the carrageenan-induced paw edema in mice.

Conclusion:

The analgesic and anti-inflammatory activity of the antidotes were comparable with aspirin.     

Antinociceptive and anti-inflammatory effects of the ethanol extract of Alpinia conchigera rhizomes in various animal models

Alpinia conchigera Griff. (Zingiberaceae), locally known to the Malays as “lengkuas ranting”, is native to Peninsular Malaysia. The Malays traditionally used it to treat infection and rashes, and as a health drink. This study evaluated the analgesic and anti-inflammatory activities of the ethanol extract of A. conchigera rhizomes in mice and rats, respectively. The analgesic activity was elucidated using the acetic acid-induced writhing test, hot plate test, and formalin test, while the anti-inflammatory activity was determined using carrageenan-induced paw edema. The extract (30, 100, and 300?mg/kg) given intraperitoneally (i.p.) exhibited antinociceptive and anti-inflammatory activities in all tests used. The range of percentage of analgesia obtained for all doses of extract in the writhing test was 50–92%, and in the early and late phases of the formalin test was 25–62% and 63–98%, respectively. In addition, naloxone (5?mg/kg) given subcutaneously (s.c.) was found to reverse the extract (300?mg/kg)-induced antinociceptive activity in the writhing, hot plate, and formalin tests. Based on the results obtained, it can be concluded that the ethanol extract of A. conchigera rhizomes possessed a peripheral and central antinociceptive activity that was mediated, in part, via the opioid receptor, as well as anti-inflammatory activity.     

Antiinflammatory and analgesic activities of Thesium chinense Turcz extracts and its major flavonoids, kaempferol and kaempferol-3-O-glucoside

The ethyl acetate, chloroform extracts, and the two flavonoids kaempferol 1 and kaempferol-3-O-glucoside 2 isolated from whole plants of Thesium chinense Turcz were investigated for their antiinflammatory and analgesic activities. For the antiinflammatory activity, carrageenan-induced hind paw edema and xylene-induced mouse ear edema models, and for the analgesic activity, the acetic acid-induced abdominal constriction test was used. The ethyl acetate extract and two flavonoids showed significant (p<0.05 and p<0.01) and dose-dependent antiinflammatory and analgesic activity. The chloroform extract was inactive in the assay.
