AbstractJobelynAcute inflammation was induced with intraplanter injection of carrageenan and increase in rat paw volume was measured using plethysmometer. The volume of fluid exudates, number of leukocytes, concentrations of malondialdehyde (MDA), and glutathione (GSH) in the fluid were measured on day 5 after induction of chronic inflammation with carrageenan in the granuloma air pouch model. RBC lysis induced by hypotonic medium as determined by release of hemoglobin was measured spectrophotometerically.JB (50–200 mg/kg) given orally produced a significant inhibition of acute inflammation induced by carrageenan in rats. It reduced the volume and number of leukocytes in inflammatory fluid in the granuloma air pouch model of chronic inflammation. It further decreased the levels of MDA in the fluid suggesting antioxidant property. JB elevated the concentrations of GSH in inflammatory exudates indicating free radical scavenging activity. It also significantly inhibited RBC lysis caused by hypotonic medium, suggesting membrane-stabilizing property.JB has in vivo anti-inflammatory activity, which may be related to its antioxidant and membrane-stabilizing properties, supporting its use for the treatment of arthritic disorder.

Objective: To investigate the qualitative composition of the acetonic extract from leaves of S. argel (AESA) and their anti-inflammatory and analgesic properties in vivo. Methods: AESA profile was established by UHPLC/DAD/ESI-MS2. AESA was subjected to the acute oral toxicity study according to the OECD-420 method. Antioxydant activity of AESA was performed by DPPH radical scavenging assay. Anti-inflammatory effects of AESA were determined in two animal models: carrageenan-induced paw edema in rats and cotton pellet-induced granuloma formation in rats. Further, anti-nociceptives activities of AESA were assessed by hot plate test, acetic acid-induced abdominal writhing test and formalin test. Results: The in vivo AESA toxicity was low. AESA expresses a maximum radical scavenging activity with a IC50 value of 36,05 μg/ml. The AESA at 250 and 400 mg/kg significantly reduced carrageen an induced paw edema by 70.09% and 85.53% 6h after carrageenan injection, respectively. AESA produced significant dose-dependent anti-inflammatory effect against cotton pellets-induced granuloma formation in rats. In addition, AESA at 250 and 400 mg/kg significantly reduced acetic acid-induced writhing by 56.83 and 80.41%, respectively. Oral administration of 250 and 400 mg/kg of AESA caused a significant dose dependent anti-nociceptive effect in both neurogenic and inflammatory phases of formalin-induced licking. AESA also impacted the pain latency in the hot plat test. Conclusion: These data suggest that AESA possesses antioxidant, anti-inflammatory and anti-nociceptive effects. These results support the traditional use of S. argel to cure pain and inflammatory diseases in the Algerian Sahara.

Aims: The aim of this work is to investigate the antioxidant and anti-inflammatory potency of novel gabapentin derivatives, which could be proven useful as neuroprotective agents. Background: Alzheimer’s Disease (AD) is one of the most common neurodegenerative disorders worldwide. Due to its multi-factorial character, no effective treatment has been obtained yet. In this direction, the multi-targeting compounds approach could be useful for the development of novel, more effective drugs against AD. Oxidative stress and inflammation are highly involved in the progression of neurodegeneration, while gabapentin has been investigated for the treatment of behavioral symptoms in AD. Objective: In this work, derivatives of cinnamic acid, trolox and 3,5-di-tertbutyl-4-hydroxybenzoic acid amidated with gabapentin methyl ester, were designed and studied. Compounds with these structural characteristics are expected to act in various biochemical pathways, affecting neurodegenerative processes. Methods: The designed compounds were synthesized with classical amidation methods, purified by flash column chromatography, and identified spectrometrically (1H-NMR and 13C-NMR). Their purity was determined by CHN elemental analysis. They were tested in vitro for their antioxidant and anti-inflammatory properties, and for their inhibitory effect on acetylcholinesterase. Their in vivo anti-inflammatory activity was also tested. Results: Those molecules incorporating an antioxidant moiety possessed inhibitory activity against rat microsomal membrane lipid peroxidation and oxidative protein glycation, as well as radical scavenging activity. Moreover, most of them presented moderate inhibition towards lipoxygenase (up to 51% at 100μΜ) and acetylcholinesterase (AchE) (IC50 up to 274μΜ) activities. Finally, all synthesized compounds presented in vivo anti-inflammatory activity, decreasing carrageenan-induced rat paw edema up to 53% and some of them could inhibit cyclooxygenase significantly. Conclusion: These results indicate that the designed compounds could be proven useful as multi-targeting molecules against AD, since they affect various biochemical pathways associated with neurodegeneration. Thus, more effective drugs can be obtained, and possible adverse effects of drug combination can be limited.

Introduction and Aim: Plants are considered to be novel source of active compounds having pharmacological properties and help in the development of therapeutic agents. Hence, this study was undertaken to evaluate the antioxidant, anti-inflammatory, analgesic and anti-proliferating activity of aqueous and methanolic leaf extracts of Grewia heterotricha Mast. Materials and Methods: The aqueous and methanolic leaf extracts of the plant were assessed for their in-vitro antioxidant activity by DPPH radical scavenging activity, in-vivo anti-inflammatory activity by carrageenan induced rat paw edema method, in-vivo analgesic activity by acetic acid-induced writhing test and in-vitro anti- proliferating activity by MTT assay. Results: The methanolic extract had shown very significant DPPH radical scavenging activity with IC50 value 98.95?g/ml than aqueous extract and showed a significant reduction in the paw volume of rats at the concentration of 100 mg/kg body weight indicating potent anti-inflammatory activity compared with the reference standard Diclofenac sodium. Both the extracts showed significant analgesic effect (p<0.001) in acetic acid-induced pain models in a dose dependent manner. The methanolic extract showed higher analgesic activity compared to aqueous extract by inhibiting the pain indicated by a decrease in the number of writhes. In addition, both the extracts showed a decrease in MCF-7 cell viability at the concentration of 550µg/ml. Compared to the aqueous extract, MEGH has shown more cytotoxic effect on the cancer cell lines. Conclusion: The results suggest that both aqueous and methanolic extracts of Grewia heterotricha Mast. leaves possess potent antioxidant, analgesic, anti-inflammatory and anti-proliferating properties, which supports the use of the plant in traditional medicine. Further investigation is required to illuminate on its active compounds.   Keywords: Analgesic; anti-inflammatory; DPPH; cytotoxic.

Aims: The present study evaluates the anti-inflammatory and antioxidant activity of the crude dichloromethane (CDCME), ethyl acetate (CEAE), and methanol (CMeE) extracts from the plant Oldenlandia corymbosa L. Background:Oldenlandia species have been popular among the people of the Indian subcontinent to treat several types of internal and external inflammation for a long time. Plant decoctions have been used to battle inflammation in cases of tonsilitis, pneumonia and cholecystitis, among others. Objective: The present work designed to demonstrate the properties of the previously mentioned plant extracts to prevent inflammation both in vivo and in vitro. This work is the first investigation of such extracts from this species and their relationship with anti-inflammatory activity. Method: The anti-inflammatory properties of the Oldenlandia corymbosa L. extracts were evaluated in vitro with the Red Blood Cell (RBC) membrane stabilization method and the protein denaturation method and in vivo with the carrageenan-induced paw oedema method. Furthermore, the free radical scavenging activity of the extracts was carried out with the 1,1-diphenyl-2- picrylhydrazyl (DPPH) radical oxidation, total antioxidant capacity and iron reduction assay. Result: Both in vivo and in vitro studies showed that CDCME had the most predominant effects with the value of 80.5% for RBC membrane stabilization, 60% for inhibition of protein denaturation at the concentration of 1000 µg/mL and 63.28% (after 3 h, * p < 0.05) for inhibition of paw oedema (300 mg/kg bwt) compared to carrageenan-induced mice. The free radical scavenging activity was studied by DPPH, total antioxidant and reducing activity assay. CDCME showed scavenging activity in all the methods and an IC50 value of 473.86 µg/mL for DPPH method. Conclusions: The findings of the study remarked that CDCME of the plant has strong anti-inflammatory and antioxidant effects that validate the traditional use of the plant to get remedy from pain.

The purpose of this study was to evaluate the in vivo biological potential of new azetidine-2-one derivatives of ferulic acid (6a–f). First, the in vivo acute toxicity of azetidine-2-one derivatives of ferulic acid on Swiss white mice was investigated and, based on the obtained results, it can be stated that the studied derivatives belong to compounds with moderate toxicity. The in vivo anti-inflammatory potential of these derivatives was determined in a model of acute inflammation induced by carrageenan in rats and in a chronic inflammation model induced in rats using the granuloma test. In the acute inflammation model, all the studied compounds had a maximum anti-inflammatory effect 24 h after administration, which suggests that these compounds may be classified, from a pharmacokinetic point of view, in the category of long-acting compounds. The most active compound in the series was found to be compound 6b. In the case of the chronic inflammation model, it was observed that the studied compounds (6a–f) reduced the formation of granulation tissue compared to the control group, having an intense effect of inhibiting the proliferative component. The most important inhibitory effect of inhibiting the proliferative component was recorded for compound 6b. Additionally, the investigation of liver function was performed by determining the serum levels of liver enzymes aspartate transaminase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LDH) and bilirubin (total and direct). The results showed that, in the series of azetidin-2-one derivatives, the liver enzymes concentration values were close to those recorded for the reference anti-inflammatories (diclofenac sodium and indomethacin) and slightly higher compared to the values for the healthy control group. At the end of the experiment, the animals were euthanized and fragments of liver, lung, and kidney tissue were taken from all groups in the study. These were processed for histopathological examination, and we noticed no major changes in the groups treated with the azetidine 2-one derivatives of ferulic acid compared to the healthy groups.

Inflammation and oxidative stress are involved in cardiovascular diseases. Nitrogen monoxide participates in the regulation of endothelial processes. Thus, derivatives of classic nonsteroidal anti-inflammatory drugs (NSAIDs), trolox or cinnamic acids esterified with 2-(nitrooxy)ethanol were designed and studied. It was found that the nitrogen monoxide (NO) releasing activity was comparable to that of S-nitroso-N-acetylpenicillamine. The nitrooxy derivatives decreased potently lipid indices in the plasma of hyperlipidaemic rats (30–85%). All compounds presented increased anti-inflammatory activity in vivo, inhibiting carrageenan-induced rat paw oedema as high as 76%, up to six times higher than that of the parent acids. Lipoxygenase inhibitory activity was significant for most of them, although the parent molecules exerted a minor effect (IC50 > 0.2 mM). Those compounds incorporating an antioxidant structure inhibited rat microsomal membrane lipid peroxidation strongly and possessed radical scavenging activity. These results indicated that the described compounds could act at different targets in multifactorial diseases, further limiting the possible adverse effects of drug combinations.

Arthrophytum scoparium is plant commonly used in folk medicine in Algeria to treat numerous human diseases especially infectious, Rheumatism, diabetes and cancer. However, its anti-inflammatory activity and the underlying mechanisms have not been studied systematically. The present study aims to assess both the in vitro and in vivo anti-inflammatory potential and antioxidant activity of the plant. Results showed that A. scoparium chloroform extract (ChE) contains the largest amount of phenolic and flavonoid compounds. In-vitro bioassay consisted of investigating the effect of the plant extracts against protein denaturation (BSA and egg albumin). In-vivo anti-inflammatory activity was evaluated by measuring the percentage inhibition of carrageenan-induced rat paw edema after oral administration of the extracts. Results showed that inhibition of protein denaturation was maximum in case of A. scoparium crude extract (CrE) with dose dependant manner. Similarly in the in-vivo study, carrageenan induced inflammation was significantly antagonized by CrE with inhibition of 87.02% at 400 mg/kg. CrE extracts showed the highest scavenger effect against hydroxyl and hydrogen peroxide. The CrE showed potent anti-inflammatory activity in both the conditions in vivo and in vitro. In conclusion different A. scoparium extracts scavenged reactive oxygen species efficiently; it may be due to the presence of its flavonoids and polyphenols. These results support the traditional use of this plant. Keywords: Arthrophytum scoparium, polyphenols, anti-inflammatory activity, radical scavenging activity.
