Rosmarinic acid is commonly found in species of the Boraginaceae and the subfamily Nepetoideae (Lamiaceae). It has a number of interesting biological activities, for example, antiviral, antibacterial, anti-inflammatory, and antioxidant. The aim of the present study was to investigate the effect of the i.p. administration of caffeic and rosmarinic acid (5 and 10 mg/kg) on anti-inflammatory and nociceptive response using carrageenan-induced pleurisy model and tail-flick assay in rats. The analysis of cells in the pleural exudates revealed a reduction of 66% of the number of leukocytes that migrated to the pleural cavity in the animals treated with 5 mg/kg caffeic acid, and of 92.9% for the animals treated with 10 mg/kg in comparison with the control group. These exudates showed a balanced distribution of polymorphonuclear (PMN) and mononuclear (MN) cells, differently from the control group, in which PMN cells were predominant. The analysis to tail-flick latency was increased in the group treated with 10 mg/kg caffeic acid characterizing a nociceptive response. While there was no difference between control group and animals treated with rosmarinic.

Abstract Objectives Several cultivars of Allium cepa L. have been studied for anti-inflammatory and analgesic activities but there is inadequate information on such biological activities of the concentrated extracts of the Nigerian grown red cultivar A. cepa bulb. Methods The anti-inflammatory models used in this study were Carrageenan-induced paw oedema and formalin-induced paw lick in rats, while acetic acid-induced abdominal writhing, hot plate reaction, hot water tail flick tests in mice were the analgesic models. Results At 30 min post-induction (pi), the inhibition of paw oedema (62.50%) by 200 mg/kg of methanol extract of red cultivar A. cepa bulb (MERCACB) was significantly (p<0.001) higher than that of indomethacin (15.63%) at 10 mg/kg. The paw oedema inhibition at 60 min pi by MERCACB (76.92%) was significantly higher than that of indomethacin (41.03%). At the early phase of formalin paw-lick test, the pain reaction time (PRT) of rat treated with MERCACB (400 mg/kg) was significantly lower than that of indomethacin and the control groups. The hotplate test revealed that PRT of mice treated with 800 mg/kg of MERCACB were significantly (p<0.01) longer in comparism to indomethacin and control groups. The PRT of mice subjected to thermal pain due to hot water and treated with 800 mg/kg of MERCACB was significantly (p<0.05) longer than that of the control group. Conclusions These findings indicate that MERCACB possesses potent anti-inflammatory and analgesic properties which confirm the traditional use of the plant for the treatment of inflammatory diseases and may be useful as a future therapeutic agent.

Medicinal plants hold a significant place as alternative treatments available for inflammatory diseases, with many phytoconstituents being frequently tested in vitro for their biological activities. In the current study, we investigated the in vivo anti-inflammatory properties of a novel active gel formulation, combining Achillea millefolium and Taxodium distichum essential oils with extracts of Aesculus hippocastanum seeds and Plantago lanceolata leaves. The toxicity of the obtained extracts and volatile oils was determined using the invertebrate model based on Daphnia magna. Anti-inflammatory potential was evaluated by the plethysmometric method on Wistar rats, expressed as the inhibition of the inflammatory oedema (%IIO), while the antinociceptive response was determined on NMRI mice, according to the tail-flick latency method. The tested gel’s efficacy was similar to the 5% diclofenac standard (maximal %IIO of 42.01% vs. 48.70%, respectively), with the anti-inflammatory effect being observed sooner than for diclofenac. Our active gel also produced a significant prolongation of tail-flick latencies at both 60 and 120 min, comparable to diclofenac. Consequently, we can imply that the active constituents present in vivo anti-inflammatory properties, and the prepared gel may be suited for use as an alternative treatment of topical inflammatory conditions.

Hepatic Lipid Peroxidation

Alcohol is a severe hepatotoxicant that causes a variety of liver disorders. Rosmarinic acid (RA), a natural phenol, shows some biological activities, including antioxidant and anti-inflammatory effects. We investigated the effects of RA (10 mg/kg) against ethanol-induced oxidative damage and hepatotoxicity in rats. Animals received ethanol (4 g/kg, i.g.) and (or) RA (10 mg/kg, i.g.) daily for 4 weeks. At the end of the treatment period, rats were weighed and use for biochemical, molecular, and histopathological examinations. Ethanol increased hepatic lipid peroxidation (P < 0.001) and decreased hepatic levels of reduced glutathione (P < 0.01), catalase (P < 0.05), and superoxide dismutase (P < 0.001) compared with control group. RA prevented the prooxidant and antioxidant imbalance induced by ethanol in liver. Furthermore, RA ameliorated the increased liver mass, serum levels of ALT, AST, LDH, TNF-α, and IL-6 in ethanol group. Necrosis and infiltration of inflammatory cells in liver parenchyma were attenuated by RA treatment. Our findings showed that RA prevents ethanol-induced oxidant/antioxidant imbalance and liver injury in an experimental model of ethanol-induced hepatotoxicity. Therefore, RA may be a good candidate to protect against ethanol-induced hepatotoxicity; this deserves consideration and further examination.

Background: The use of natural compounds in relieving pain has been commonplace since ancient times and their use is currently increasing. Objectives: Given that analgesic and anti-inflammatory effects of Kombucha have not been studied, this study was designed to examine these effects in vitro. Methods: In this experimental study, rats were divided into four groups. The control group received normal saline i.p in the same amount of the drug. The other groups received Kombucha tea i.p at 250, 500, and 1000 mg/kg. Tail-flick and acetic acid tests were used to evaluate the analgesic effects of Kombucha tea and the xylene-induced ear inflammation test to evaluate the anti-inflammatory effects of Kombucha tea. Results: Kombucha tea at three doses 250, 500, and 1000 mg/kg significantly reduced the number of writhings in the acetic acid test. Kombucha tea at 1000 mg/kg significantly increased pain tolerance in the tail-flick test. Kombucha tea at 250 and 500 mg/kg could significantly reduce inflammation in the rat’s ear. Conclusions: The results of this study indicate that Kombucha has analgesic effects in rats and can be considered in future treatments.

The present study was conducted to evaluate the analgesic potential of the new triamilide macrolide antibiotic, tulathromycin, at 20 and 40 mg/kg of body weight (BW), subcutaneously against acute pain in mice. Acute pain was induced either chemically (using acetic acid-induced writhing and formalin-induced pain tests) or thermally (using hot-plate, and tail-flick tests). In the acetic acid-induced writhing test, tulathromycin induced a dose-dependent and significant decrease in the number of writhes compared with the control group. In the late phase of the formalin test, a significant decline in hind paw licking time compared with the control group was observed. In the hot-plate and tail-flick tests, tulathromycin caused a dose-dependent and significant prolongation of latency of nociceptive response to heat stimuli, compared with the control group. These findings may indicate that tulathromycin possesses significant peripheral and central analgesic potentials that may be valuable in symptomatic relief of pain, in addition to its well-established antibacterial effect.

Caffeic acid (CA) and its phenethyl ester (CAPE) are naturally occurring hydroxycinnamic acids with an interesting array of biological activities; e.g., antioxidant, anti-inflammatory, antimicrobial and cytostatic. More recently, several synthetic analogs have also shown similar properties, and some with the advantage of added stability. The actions of these compounds on the cardiovascular system have not been thoroughly explored despite presenting an interesting potential. Indeed the mechanisms underlying the vascular effects of these compounds particularly need clarifying. The aim of this paper is to provide a comprehensive and up-to-date review on current knowledge about CA and its derivatives in the cardiovascular system. Caffeic acid, CAPE and the synthetic caffeic acid phenethyl amide (CAPA) exhibit vasorelaxant activity by acting on the endothelial and vascular smooth muscle cells. Vasorelaxant mechanisms include the increased endothelial NO secretion, modulation of calcium and potassium channels, and modulation of adrenergic receptors. Together with a negative chronotropic effect, vasorelaxant activity contributes to lower blood pressure, as several preclinical studies show. Their antioxidant, anti-inflammatory and anti-angiogenic properties contribute to an important anti-atherosclerotic effect, and protect tissues against ischemia/reperfusion injuries and the cellular dysfunction caused by different physico-chemical agents. There is an obvious shortage of in vivo studies to further explore these compounds’ potential in vascular physiology. Nevertheless, their favorable pharmacokinetic profile and overall lack of toxicity make these compounds suitable for clinical studies.

Pani heloch (Antidesma montanum) is traditionally used to treat innumerable diseases and is a source of wild vegetables for the management of different pathological conditions. The present study explored the qualitative phytochemicals; quantitative phenol and flavonoid contents; in vitro antioxidant, anti-inflammatory, and thrombolytic effects; and in vivo antipyretic and analgesic properties of the methanol extract of A. montanum leaves in different experimental models. The extract exhibited secondary metabolites including alkaloids, flavonoids, flavanols, phytosterols, cholesterols, phenols, terpenoids, glycosides, fixed oils, emodines, coumarins, resins, and tannins. Besides, Pani heloch showed strong antioxidant activity (IC50 = 99.00 µg/mL), while a moderate percentage of clot lysis (31.56%) in human blood and significant anti-inflammatory activity (p < 0.001) was achieved with the standard. Moreover, the analgesic and antipyretic properties appeared to trigger a significant response (p < 0.001) relative to in the control group. Besides, an in silico study of carpusin revealed favorable protein-binding affinities. Furthermore, the absorption, distribution, metabolism, excretion, and toxicity analysis and toxicological properties of all isolated compounds adopted Lipinski’s rule of five for drug-like potential and level of toxicity. Our research unveiled that the methanol extract of A. montanum leaves exhibited secondary metabolites that are a good source for managing inflammation, pyrexia, pain, and cellular toxicity. Computational approaches and further studies are required to identify the possible mechanism which responsible for the biological effects.

The synthesis of new NSAIDs with improved efficacy and selectivity towards COX2, which encouraged by the various biological activities of 1,2,4-triazoles and 1,3,4-thiadiazoles. In this experiment, the production of 1,2,4-triazolothiadiazoles derivatives from Ibuprofen, Naproxen and Indomethacin. We have enhanced anti-inflammatory and analgesic activities by conventional method and microwave-assisted technique, and then compare the time consuming by reaction and yield percent of the product in both way, besides evaluation of anti-inflammatory action of the target compounds by pharmacological test with predictable selectivity towards COX-2 enzyme. Synthesis of the target compounds (P1a-3b, N1a-3b and I1a-3b) has been successfully accomplished by checking purity, characterization, also identification of the synthetic compounds which detected by estimation of physical properties, FT-IR and ¹H-NMR spectroscopy. In vivo potent anti-inflammatory activity of the ending compounds is evaluating in rats utilizing egg-white prompted edema model of inflammation. The experienced compounds (P1a-3b, N1a-3b and I1a-3b) and the reference drugs (Ibuprofen, Naproxen and Indomethacin) produced significant reduction in paw edema in compare to the effect of control group. Wholly tested compounds produced considerable decrease of paw edema in contrast to control group. However, compounds (P3b, N3b and I1b) have considerable more paw edema declining than Ibuprofen, Naproxen and Indomethacin. Intermediate and target compounds are synthesis by microwave method have better result by time and yield in compare with conventional way. The synthesized compounds (Pa1-3b and N1a-3b) may exhibit expected selectivity towards COX-2 enzyme properly due to their large size than its parent Ibuprofen, Naproxen.

Abstract Affordable and practical synthesis methods in drug development have always been very attractive. Herein, microwave assisted synthesis was utilized to prepare piperazine substituted 5-chloro-2(3H)-benzoxazolone derivatives in 5 minutes. Structural characterization of these 5-chloro-2(3H)-benzoxazolone derivatives was achieved by IR, NMR, ESI-MS and elemental analysis. Since these types of compounds have been shown to have anti-inflammatory and analgesic activities there biological activities were also examined. Indomethacin (INDO) and acetylsalicylic acid (ASA) were used as reference. Carrageenan-induced hind paw edema in mice test was used to study anti-inflammatory activity. Compound 1 (100 mg / kg dose) showed the longest anti-inflammatory activity among the title compounds synthesized. For the analgesic activities, both hot-plate and tail-flick tests were employed. Compound 3 was found to have the highest activity in the hot-plate test whereas in the tail-flick test, compounds 1 and 2 showed higher anti-nociceptive activity.

Purpose: This study was designed to investigate the anti-nociceptive, anti-inflammatory and hepatoprotective activities of the methanol extract of Mazus pumilus (Mazaceae) herb. Methods: Anti-nociceptive activity was determined using hot plate, tail flick and acetic acid-induced writing methods. Carrageenan-induced rat paw edema (0.1 mL of 1 %) model was used for the assessment of anti-inflammatory activity. The methanol extract was administered orally at three different doses (150, 300 and 600 mg/kg) to three separate groups in all the experiments. Diclofenac sodium (50 mg/kg) was used as standard drug while control group received DMSO (1 %, 10 mL/kg). The hepatocurative effect of methanol extract of M. pumilus (400 mg/kg) was determined in isoniazid (50 mg/kg) and rifampicin (100 mg/kg) induced liver injury. Silymarin (100 mg/kg) was used as standard drug for comparison. The control group received distilled water (10 mL/kg). Preliminary phytochemical screening was also carried out. Results: The methanol extract of M. pumilus significantly (p < 0.05) augmented latency time and reduced the number of writhes in the pain models at all doses used for the assessment of antinociceptive actions. The anti-inflammatory activity of different doses of extract was evaluated by measuring the reduction in the size of the paw. A significant (p < 0.05) hepatocurative effect was observed when administered after anti-tuberculosis drugs. Histopathological analysis of the liver tissues also revealed restored hepatocellular architecture. Conclusion: The results demonstrate the anti-nociceptive, anti-inflammatory and hepatoprotective effects of the methanol extract of M. pumilus, thus substantiating the ethnomedical claims associated with the herb.
