Objective: The objective of the study was to evaluate the anti-inflammatory and antinociceptive effects of Artemisia afra.Methods: Animals were randomly divided into five groups of six animals each and administered with normal saline (2 ml/kg), indomethacin (10 mg/ kg), and A. afra at doses of 100, 200, and 400 mg/kg, respectively. For the anti-inflammatory activity, carrageenan-induced paw edema was used while the hot plate and acetic acid induced-writhing tests were used to assess the antinociceptive activity.Results: Pretreatment with A. afra at a dose of 100 mg/kg did not show any significant biological effects (p>0.05) for any of the three tests, when compared against saline-treated control group. At a dose of 200 mg/kg, A. afra demonstrated significant effects (p<0.01), during the 5th h reducing carrageenan-induced paw edema by 12%. The highest dose (400 mg/kg) of A. afra demonstrated more potent effects by decreasing the carrageenan-induced paw swelling (p<0.001–0.05) during the 3rd, 4th, and 5th h, by up to 38% when compared against saline-treated control group. Both the 200 and 400 mg/kg, A. afra doses achieved a significant increase (p<0.05) in reaction time in the hot plate test. In the acetic acid-induced writhing test, pretreatment with A. afra (400 mg/kg) significantly reduced pain by 39% (p<0.01) by comparison with the saline control.Conclusion: Experimental data demonstrated that aqueous extract of A. afra possesses anti-inflammatory and antinociceptive properties in experimental acute inflammation and pain. These findings support the usage of A. afra in managing inflammation and pain in traditional practice.

Perillyl alcohol (PA) is a natural compound found in essential oils. In this study, the antinociceptive activity of PA was evaluated using acetic acid and formalin tests. The involvement of the opioid system in its mechanism of action was investigated. Potential histological changes in the hippocampus and striatum were also assessed. In the acetic acid induced writhing tests, the mice pretreated with PA exhibited significant reductions in writhing. PA inhibited formalin injected paw licking response, and naloxone partially reversed the antinociceptive activity of perillyl alcohol during the writhing test. And as for the histopathological evaluation, PA did not cause significant tissue changes. This study suggests that PA possesses antinociceptive effects without significant hippocampus or striatum neurotoxicity, and that its activity involves opioid.

Propolis is an important bee product which has been applied to the treatment of several diseases. The aim of this study was to understand the material basis of Chinese propolis on pain relief; different Chinese propolis fractions (40W, 40E, 70E, and 95E raw propolis extracted followed by 40%, 70%, or 95% ethanol) were prepared, and their antinociceptive effects were evaluated. By analyzing using UPLC-Q-TOF-MS, we showed that 40W was rich in phenolic acids, like caffeic acid, while 40E, 70E, and 95E have relatively high levels in flavonoids, like galangin, pinocembrin, and chrysin. Notably, chrysin amounts in 70E and 95E are much higher than those in 40E fraction. Antinociceptive effects by these propolis fractions were evaluated in mice using acetic acid-induced writhing test, hot plate test, and tail immersion test, respectively. We noticed that only 40E fraction showed a significant reduction on acetic acid-induced writhing test. Importantly, in the hot plate test, all groups showed their effectiveness, except for the 70E group. We also noticed that 40W, 40E, and 95E administration caused an increase in the tail withdrawal latency of the mice. These data suggested that the different antinociceptive effects of different fractions from Chinese propolis extracts are directly link to their flavonoid composition.

Rat Paw Oedema

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.

Background: In a study recently published by our research group, the compounds isoxazoline-acylhydrazone derivatives R-99 and R-123 presented promising antinociceptive activity. However, the mechanism of action of this compound is still unknown. Objective: This study aimed to assess the mechanisms involved in the antinociceptive activity of these compounds in chemical models of pain. Methods: Animals were orally pretreated and evaluated in the acetic acid-, formalin-, capsaicin-, carrageenan- and Complete Freund's Adjuvant (CFA)-induced pain models in mice. The effects of the compounds after pretreatment with naloxone, prazosin, yohimbine, atropine, L-arginine, or glibenclamide were studied, using the acetic acid-induced writhing test to verify the possible involvement of opioid, α1-adrenergic, α2-adrenergic or cholinergic receptors, and nitric oxide or potassium channels pathways, respectively. Results: R-99 and R-123 compounds showed significant antinociceptive activity on pain models induced by acetic acid, formalin, and capsaicin. Both compounds decreased the mechanical hyperalgesia induced by carrageenan or CFA in mice. The antinociceptive effects of R-99 and R-123 on the acetic acid-induced writhing test were significantly attenuated by pretreatment with naloxone, yohimbine or atropine. R-99 also showed an attenuated response after pretreatment with atropine and glibenclamide. However, on the pretreatment with prazosin, there was no change in the animals' response to both compounds. Conclusion: R-99 and R-123 showed antinociceptive effects related to mechanisms that involve, at least in part, interaction with the opioid and adrenergic systems and TRPV1 pathways. The compound R-99 also interacts with the cholinergic pathways and potassium channels.

In the present study, we investigated the antinociceptive effects of the plant Vigna unguiculata spp dekindtiana using chemical and thermal tests in mice. The peripheral and the central analgesic activities of the methanol extract and its fractions were investigated in-vivo in albino mice using acetic acid induced-writhing test and hot plate models respectively. The result of the central analgesic effect showed that the methanol extract (VUME) at 400 mg/kg produced a significant (p<0.05) delay in reaction time in mice on hot plate compared to the control. Various fractions of the extract showed more potency compared to the crude extract. In acetic writhing model, the extract and the fractions demonstrated dose dependent reduction in writhing reaction induced by acetic acid in mice. The reduction was significant when compared to control which was suggestive of the analgesic effect of the plant. It was also seen that the extract and fractions showed an improved analgesic effect compared to diclofenac used as positive control in this model. Yohimbine (alpha adrenergic receptor antagonist) and cyproheptadine (serotonergic receptor antagonist) reversed the antinociceptic effect of the fractions in the hot plate model demonstrating the possibility of adrenergic and serotonergic involvement in eliciting the analgesic effect. Naloxone on the other hand, caused a reversal only in the butanol fraction meaning that this fraction may contain active principles that may mediate their analgesic effect through the opioid mechanism. In the writhing test, yohimbine abolished the analgesic effect of both hexane and butanol fractions. This may therefore, suggest that the analgesic effect of these fractions may be mediated through adrenergic pathway. In conclusion, the plant V. unguiculata subspecies dekindtiana possesses active principles with potential analgesic activity, establishing the folkloric use of the plant in managing pain.

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

The present study was carried out to investigate the possible analgesic, neuropharmacological and cytotoxic activities of the methanolic extract of Trigonella foenum-graecum Linn. leaves. The analgesic and neuropharmacological activities of Trigonella foenum-graecum Linn. were investigated at the doses of 100mg/kg, 200mg/kg and 400mg/kg of body weight in mice. Analgesic potential of the extract was evaluated for centrally acting analgesic property using tail immersion method and peripheral analgesic actions using acetic acid-induced writhing test. In acetic acid-induced writhing test, extract produced a significant (p < 0.001) inhibition of writhing response in a dose dependent manner but maximum inhibition (93.46%) of writhing was found at 400mg/kg dose. In tail immersion method, extract caused a significant (p < 0.001) increase in latency time and the results were comparable to the standard drug Diclofenac- Sodium. In addition, neuropharmacological property of crude extract was carried out by Hole cross and Open field test. The extract significantly (p < 0.05-0.001) displayed a dose dependent suppression of motor activity, exploratory behaviour. Furthermore, the extract was subjected to Brine Shrimp lethality bioassay for primary evaluation of cytotoxicity, where the extract was found to be highly toxic to Brine Shrimp nauplii, having LC50 values of 10μg/ml while the LC50 of the reference anticancer drug vincristine sulphate was 0.66μg/ml. The results of this present study suggest that the extract possesses analgesic, cytotoxic and CNS depressant activities.
