Renewed interest in natural products as potential source of drugs led us to investigate on both the anti-inflammatory and anti-nociceptive activity of Citrus bergamia Risso et Poiteau (bergamot) essential oil (BEO). Carrageenan-induced paw edema in rats was used as an experimental model of inflammation. Because of the toxicity of furocoumarins, we performed our study by using the BEO fraction deprived of these compounds (BEO-FF). Treatment with BEO-FF led to a significant inhibition of paw edema induced by a sub-plantar injection of carrageenan. Moreover, histological examination of BEO-FF-treated rat paw biopsies showed a reduction of pathological changes typical of edema. Pre-treatment with BEO-FF significantly reduced interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α levels in the paw homogenates, as well as nitrite/nitrate and prostaglandin E2 (PGE2) content in exudates. In addition, BEO-FF possesses antioxidant properties, as determined by cell-free assays. Furthermore, results of the writhing test showed that BEO-FF elicited a pronounced analgesic response, as demonstrated by a significant inhibition of constrictions in mice receiving acetic acid, with respect to control animals, whereas the results of the hot plate test suggested that the supra-spinal analgesia participates in the anti-nociceptive effect of BEO-FF. Our study indicates that BEO-FF exerts anti-inflammatory and anti-nociceptive effects, and suggests its potential role as an anti-edemigen and analgesic drug.

Objective: Objective of the study was to synthesize and evaluate a series of novel compounds, ethyl 2-(2-cyano-3-(substituted phenyl)acrylamido)- 4,5-dimethylthiophene-3-carboxylates, for in vitro antioxidant and in vivo anti-inflammatory activities.Methods: Ethyl 2-(2-cyano-3-(substituted phenyl)acrylamido)-4,5-dimethylthiophene-3-carboxylates were synthesized by knoevenagel condensation of active methylene group of ethyl 2-(2-cyanoacetamido)-4,5-dimethylthiophene-3-carboxylate with substituted benzaldehydes. The synthesized compounds were evaluated for their in vitro antioxidant properties in three different models, viz., reduction of 1,1-diphenyl-2-pycrylhydrazyl free radical, scavenging of nitric oxide free radical, and ferric ion-induced lipid peroxidation using rat brain homogenate. Few selected compounds with good antioxidant properties were pharmacologically evaluated for anti-inflammatory activity by carrageenan-induced rat paw edema model.Results: Clean and efficient synthetic procedure was used for the preparation of series of compounds. The structures of synthesized compounds were confirmed by infrared, 1H nuclear magnetic resonance and mass spectra. The antioxidant activity data revealed that the compounds of ethyl 2-(2-cyano-3-(substituted phenyl)acrylamido)-4,5-dimethylthiophene-3-carboxylate containing phenolic substitution showed greater antioxidant activity. Hence, the active compounds were evaluated for anti-inflammatory activity and found to possess good activity. The percentage inhibition of rat paw edema obtained for the evaluated compounds was in the range of 70.2-83.1, comparable to the standard drug diclofenac (85.0%).Conclusion: The use of inexpensive, eco-friendly and readily available reagents, easy work-up and high purity of products makes the procedure a convenient and robust method for the synthesis of title compounds. The compounds of ethyl 2-(2-cyano-3-(substituted phenyl)acrylamido)-4,5- dimethylthiophene-3-carboxylate containing phenolic substitution showed greater antioxidant and anti-inflammatory activities.

This study examined the chemical composition of Neolitsea aciculata essential oil (NAE) and its biological activities. NAE was obtained by hydrodistillation of N. aciculata leaves collected in Jeju Island and analyzed by gas chromatography equipped with a mass spectrometer detector. 1-Dodecen-3-yne (12.5%), calarene (11.5%) and elemol (9.5%) were identified as the major components of NAE. The antibacterial and anti-inflammatory activities of NAE against skin pathogens were examined to determine the protective properties against acne vulgaris. NAE exhibited moderate to strong antibacterial activity against drug-susceptible and -resistant Propionibacterium acnes and Staphylococcus epidermidis, which are known as acne-causing bacteria. In addition, NAE reduced the P. acnes-induced secretion of tumor necrosis factor-α (TNF-α) and interleukin-8 (IL-8) in THP-1 cells, highlighting its anti-inflammatory effects. The DPPH radical scavenging activities of NAE also revealed moderate antioxidant properties (IC50, 21.3 μL/mL). Overall, NAE is an attractive candidate as an ingredient in skin care products.

Abstract Myrciaria plinioides D. Legrand (Myrtaceae) is a native plant of Southern Brazil, which have potential in the food industry due to its edible fruits. Many plants belonging to this genus have been used for a variety of illnesses, including inflammatory disorders due to antioxidant properties. However, therapeutic uses of M. plinioides have been poorly studied. The aim of study was to assess the anti-inflammatory and anticoagulant activities of the ethanol leaf extract of M. plinioides. In M. plinioides extract-treated RAW 264.7 cells, assessments of cell viability, TNF-α release and p38 MAPK pathway-dependent protein expression were detected. In addition, rat paw edema models were used to analyze the anti-inflammatory effect of the extract. Macrophages cell line treated with M. plinioides extract showed a slight decrease in cell viability. In LPS-stimulated macrophages treated with different concentrations of the extract for 24 h, TNF-α release was inhibited, while modulation of p38 signaling pathway and inhibition of NF-κB p65 protein expression were dose-dependent. In rats, the extract inhibited the formation of paw edema, while an inhibitory effect on trypsin-like enzymes derived from mast cells was seen. Furthermore, the extract presented anticoagulant activity via extrinsic pathway, being able to block specifically factor Xa and thrombin. The study suggests that extract possess potent anti-inflammatory and anticoagulant effects. M. plinioides present great biological potential as a source for the development of anti-inflammatory and anticoagulant drugs. Additional studies can be proposed to better elucidate the mechanism by which M. plinioides exerts its effects.

Crotamine, a toxin found in the venom of the South American rattlesnake Crotalus durissus terrificus, has been reported to have antinociceptive effects. We purified recombinant crotamine expressed in Escherichia coli and investigated its antinociceptive and anti-inflammatory effects using the hot-plate test, acetic-acid-induced writhing method, and formalin test in mice. Recombinant crotamine was administered intraperitoneally (0.04–1.2 mg kg−1) or intraplantarly (0.9–7.5 μg 10 μL−1) before the tests. The paw volume was measured with a plethysmometer. To evaluate the antagonistic and anti-inflammatory effects of naloxone, subcutaneous naloxone (4 mg kg−1) or intraplantar naloxone (5 μg 10 μL−1) was administered before recombinant crotamine. For tumor necrosis factor (TNF)-α assays, blood was drawn 3 h after formalin injection and measured using enzyme-linked immunosorbent assay. Intraperitoneal and intraplantar recombinant crotamine had antinociceptive and anti-inflammatory effects, neither of which were affected by pre-treatment with naloxone. The mean serum TNF-α levels were significantly lower in the intraperitoneal recombinant crotamine (0.4 and 1.2 mg kg−1) or intraplantar (2.5 and 7.5 μg 10 μL−1) recombinant crotamine groups than in the saline group and were not affected by naloxone pre-treatment. In conclusion, recombinant crotamine possesses significant antinociceptive and anti-inflammatory effects that do not appear to be related to the opioid receptor. The antinociceptive and anti-inflammatory effects of intraperitoneal or intraplantar recombinant crotamine are related to TNF-α.

AbstractBackground and objectivesAloperine (ALO) is an alkaloid compound and presents in several medicinal plants. This study was undertaken to investigate the anti-nociceptive and anti-inflammatory activities of ALO on various chemical- and thermal-induced hypersensitivity models in mice.MethodsThe anti-nociceptive effect of ALO was evaluated using acetic acid-induced writhing test, hot plate test, tail flick test, formalin test, ear swelling test, locomotor activity test, rota-rod test and carrageenan-induced paw edema test in mice. Inflammatory cytokines including interleukin-10 (IL-10), tumor necrosis factor α (TNF-α), interleukin-1 beta (IL-1β) and prostaglandin E2 (PGE2) expression were examined in ALO- and vehicle-treated mice.ResultsThe results showed that ALO significantly attenuated acetic acid-induced writhing numbers in mice in a dose-dependent manner. ALO showed no effect on prolonging latency in the hot plate test and the tail-flick test. ALO showed analgesic activity in the inflammatory phase of formalin-induced pain. Its anti-inflammatory effect was also confirmed in the ear-swelling test. In the carrageenan-induced paw edema model, ALO significantly and dose-dependently reduced the carrageenan-induced paw edema, decreased the contents of TNF-α IL-1β and PGE2, but increased the IL-10 production. On the other hand, ALO showed no influence on the rota-rod performance time or on spontaneous locomotor activity.ConclusionIt is concluded that ALO has both anti-inflammatory and analgesic effects, especially in the field of inflammation pain.ImplicationsOur findings support the hypothesis that ALO ameliorates inflammatory pain induced by chemical and thermal stimuli and provides a scientific basis for the resource development and clinical use of aloperine.
