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.

Objective: Because of adverse side effects, caused by NSAIDs, tolerance, and dependence induced by opiates, the use of these analgesic agents has not been successful in all cases. Therefore, alternative analgesic drugs from plant sources are the new target now days. The objective of this study was to evaluate the analgesic activity of ethanolic extracts of stem barks and leaves of Ficus religiosa. Methods: The analgesic activity of ethanolic extract of stem barks and leaves was evaluated in the Swiss albino mice model using acetic acid-induced writing response and Eddy’s hot plate method. Analgesic activity was demonstrated with the percentage inhibition of acetic acid induced writings and the percentage increased in latency time of paw licking. The potency of test extracts was compared with standard drug, Diclofenac. Results: Ethanolic extract of leaves and bark of F. religiosa showed potential analgesic activity from both methods. From Eddy’s hot plate model, it was observed that the percentage of increased latency time at 90 min by ethanolic extract of leaves and stem bark was found to be 70.81 % (8.54 min) and 70.78 % (8.53 min) respectively at a dose of 400 mg/kg. Both of these results are statistically significant (p<0.05) as compared to the test group. Furthermore, both of these extracts showed the dose-dependent and time-dependent increased in latency time and these results are compared to that of standard drug Diclofenac. Similarly, ethanolic extract of leaves and stem at 400 mg/kg significantly inhibited the number of writhings induced by acetic acid. The percentage inhibition of writhings by ethanolic extract of leaves at a dose of 400 mg/kg was 68.47 % which was similar to that of standard drug Diclofenac (68.47 %). However, ethanolic extract of bark showed relatively lower percentage inhibition (60.79 %) as compared to leaf extract and standard, but the result was significant as compared to that of the test group (p<0.05). Conclusion: Ethanolic extracts of F. religiosa stem bark and leaf possess both central and peripheral analgesic properties and these effects may be beneficial for the management of pain.

The present study was aimed to evaluate the analgesic and anti-inflammatory properties ofCastanospermum australeand to profile phytochemicals by GC-MS. The ethanolic extracts were prepared by successive solvent extraction using Soxhlet apparatus. The analgesic activity was analyzed by hot plate method and acetic acid-induced writhing test whereas anti-inflammatory study was done by carrageenan induced paw oedema model. The acute toxicity study revealed that ethanol extracts of leaf and bark ofC. australewere safe even at a higher dose of 2000 mg/kg whereas ethanol extract of seed was toxic at the same dose. In both hot plate method (5.85 s) and acetic acid-induced writhing test (57%), the leaf ethanol extract exhibited significant analgesic activity (P<0.001) at a dose of 400 mg/kg. The anti-inflammatory activity of leaf extract was exhibited by the reduction in paw linear diameter by 64.76% at 400 mg/kg in carrageenan induced paw oedema. The GC-MS analysis of the ethanol extract of leaf revealed sixteen major compounds of which 1,7-dimethyl-4,10-dioxa-1,7-diazacyclododecane, (+)-N-methylephedrine, and permethylspermine were found to be pharmaceutically and the most important. These findings justify thatC. australecan be a valuable natural analgesic and anti-inflammatory source which seemed to provide potential phytotherapeutics against various ailments.

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.

Abstract Background The study was conducted to evaluate the analgesic, anti-inflammatory, antipyretic properties of ethanolic extract of Tacca integrifolia rhizome (EETI) in mice and cytotoxic effects in brine shrimp nauplii followed by a PASS prediction study for some isolated compounds of T. integrifolia. Additionally, this experiment included the in silico molecular docking and ADME/T property analyses of some phytochemicals. Methods Formalin- induced paw licking test and acetic acid-induced writhing test for analgesic activity, carrageenan-induced paw edema test for anti-inflammatory potential and Brewer’s yeast-induced pyrexia test for antipyretic activity were applied. Antinociceptive and antineoplastic activity for breast cancer were revealed with PASS program. Schrodinger suite 2015 was used to evaluate the binding interaction and ADME/T properties of selected phytoconstituents with estrogen receptor alpha. Results In formalin-induced paw licking test, EETI at the doses of 200 and 400 mg/kg BW showed highly significant inhibition of writhing in both neurogenic and inflammatory phases. While EETI also exhibited highly significant, compared to control, writhing inhibition for both the doses in acetic acid-induced writhing test. Moderate anti-inflammatory effect at a dose of 400 mg/kg BW was noticed in paw-edema test. It also showed 77.51% of maximum antipyretic effect which was significantly effective compared to standard drug paracetamol (150 mg/kg) in Brewer’s yeast-induced pyrexia test. The EETI showed potential cytotoxic activity with LC50 value of 114.46 μg/mL. The PASS prediction revealed the potential antinociceptive and antineoplastic activity of target compounds. The compounds betulinic acid, quercetin-3-α-arabinoside, catsanogenin were found to be effective in molecular docking study. Conclusion It is evident that the EETI possesses highly significant analgesic activity with remarkable anti-inflammatory and antipyretic activity. The phytoconstituents have potential antinociceptive and antineoplastic (breast cancer) activity. Graphical abstract

Abstract Background This study was conducted to evaluate the analgesic activity of different extracts of Lippia alba (L. alba) along with in silico evaluation of analgesic activity of the isolated compounds from L. alba against cyclooxygenase-2 enzyme and ADME/T analysis of isolated compounds. Method In vivo analgesic activity of different extracts of L. alba was evaluated by acetic acid-induced writhing, tail immersion and hot plate on Swiss albino mice of either sex. In silico activity of the isolated compounds and ADME/T analysis were performed by Schrödinger-Maestro (Version 10.1) and OSIRIS Data warrior (version 4.6.1) softwares. Results Three different extracts (Methanolic extract: ME; Petroleum ether extract: PEE; Dichloromethane extract: DCME) of 250 mg/kg and 500 mg/kg doses were used in the experiments to evaluate analgesic activity. In acetic acid-induced writhing test, significant results were seen for PEE (500 mg/kg) and DCME (500 mg/kg), which were 53.09 ± 2.87 & 50.09 ± 4.24%, respectively. In tail immersion test, the best latency time was found at + 60 min for PEE (500 mg/kg) which is (5.65 ± 0.25) sec. For hot plate test, DCME at a dose 500 mg/kg showed the highest increase in latency time, which was 13.48 ± 0.33 s. In the case of in silico evaluation of analgesic activity, the compounds such as geranial, neral, (E)-caryophyllene, caryophyllene oxide, mussaenide, and 8-epi-loganin meet the condition of Lipinski’s rule of five. Among these safe compounds, 8-epi-loganin showed the best docking score of − 8.17 kcal/mol against cyclooxygenase-2 enzyme (PDB ID: 6COX), which was almost similar to that of the standard drug, Celecoxib (− 11.11 kcal/mol). Conclusion In conclusion, L. alba can be a potent source of analgesic medicine and further modification and simulation studies are required to establish the effectiveness of 8-epi-loganin.

AbstractIn the present synthesis a series of 1-(1-methyl-2-oxo-1,2-dihydroquinolin-4-yl)-2-substituted phenylpyrazolidine-3,5-diones were prepared. By the reaction of N-methylbenzenamine with diethyl malonoate 4-hydroxy-1-methylquinolin-2(1H)-one were prepared, which on treatment with posphoryl chloride converted into 4-chloro-1-methylquinolin-2(1H)-one. Subsequently with substituted phenyl hydrazines 1-methyl-4-(2- substitutedphenylhydrazinyl)quinolin-2(1H)-one were obtained, which on reaction with diethyl malonate gave 1- (1-methyl-2-oxo-1,2-dihydroquinolin-4-yl)-2-substituted phenylpyrazolidine-3,5-diones. All structures were characterized by IR, 1HNMR & mass spectrometry. Further all the synthesized compounds were evaluated for their anti-nociceptive activity in mice by Eddy’s hot plate and acetic acid induced writhing response. All compounds have shown the activity. In hot plate model compounds QAA-04c and QAA-04d have given more activity than standard, whereas in case of acetic acid induced writhing model compounds QAA-04a and QAA- 04d have given significant analgesic activity which is comparable with the standard drug. Compound QAA-04b has shown least analgesic activity. Compound QAA-04a was almost equal in activity to the standard drug diclofenac sodium and was considered as the lead molecule.

This study was to investigate the anti-inflammatory and analgesic activities of the total saponins extracted from fermented Polygala japonica Houtt (FPH) compared with that of unfermented Polygala japonica Houtt (UFPH). The total saponins extracted from FPH and UFPH were evaluated for anti-inflammatory activity in xylene-induced ear swelling and acetic acid-induced vascular permeability models in mice, analgesic activity in acetic acid-induced writhing and hot plate models in mice. The total saponins extracted from FPH had the significant anti-inflammatory (p<0.001) and analgesic (p<0.01) activities with the doses of 6 g/kg b.w. in mice. The results of this experimental study thus strongly support the potential significant use of the total saponins extracted from FPH for pain and inflammatory.
