    Opis:
    New hydrazone derivatives were synthesized from 4-chloro-2-(methylthio)pyrimidine-5-carbohydrazide. Synthesized compounds were characterized by IR, 1H-NMR, 13C-NMR, mass spectral data and elemental analysis. All compounds were investigated for analgesic and anti-inflammatory activity with hot plate test and biochemical assay, respectively. The results of anti-inflammatory activity showed that compound 2t had maximal Lipoxygenase (LOX) inhibition (66.30%) whereas inhibitions of 2a, 2c, 2i, 2k, 2l, 2m, 2p, 2s and 2u were observed between approximately 45-15 %. Our results also indicated that 15 compounds of 21 had analgesic effect in hot plate test. Analgesic effect of 2l, 2s, 2t began earlier than others while effect of 2i began at latest time. According to the activity results, compound 2t have significant analgesic and anti-inflammatory effects.

    Opis:
    In this study we investigate the antioxidant, anti-inflammatory, and antidiabetic activities of ethanolic leaves extracts of three selected varieties of Phoenyx dactylifera L. namely: “Ghars”, “Deglet Nour” and “Hamraya”. The assessment of the antioxidant potential of crude leaves extracts, using superoxide anions inhibition, DPPH and total antioxidant activity essays, was carried out. Furthermore, the anti-inflammatory properties of the extracts were determined by measuring the inhibition of nitric oxide (NO) production. Moreover, the antidiabetic effect was evaluated by inhibition of α-amylase enzymes. The total phenolic content measured by Folin-ciocalteu method was as well conducted. The raw leaves extracts of the selected varieties was found to contain a high content of total phenolic content (342.45 mg GAE/gDW for GE) and therefore exhibited a higher antioxidant activity and inhibitory effect of radicals scavenging activity against DPPH and superoxide anion (IC50 = 7.44 μg/mL and 39.11 μg/mL respectively). The three varieties exhibited significant inhibition nitric oxide using in-vitro assay (IC50 = 240.28 μg/mL for GE). The extracts also displayed high inhibition actions against α-amylase enzymes. The results suggest that the leaves of the three selected varieties of Phoenyx dactylifera can be considered as a good source of natural antioxidant and anti-inflammation drugs as well as potent antidiabetic medicine.

    Opis:
    Introduction: Potato (Solanum tuberosum L.) is an important vegetable crop in Syria. Potato tuber moth Cussonia barteri is a small tree that grows in the sub-Saharan part of Africa. Various parts of the plant are used for the treatment of a variety of ailments in ethno-medicine. Objective: To evaluate the anti-inflammatory and analgesic effect of the methanol leaf extract of Cussonia barteri. Material and methods: The leaves were air-dried, powdered and repeatedly extracted with methanol using a Soxhlet apparatus. The resulting methanol extract (100, 200 and 400 mg/kg) was evaluated for antiinflammatory activity using carrageenan-induced paw oedema, xylene-induced ear oedema and formalininduced arthritis tests. Analgesic effect was evaluated using acetic acid-induced mouse writhing, hot plate and tail flick tests. Results: All doses of the extract significantly (p<0.05) reduced carrageenan-induced paw oedema, however the 400 mg/kg dose gave a sustained effect. The extract significantly inhibited xylene induced ear oedema at all doses. There were no significant (p>0.05) reductions in paw swellings due to formalin. In the acetic acid induced writhing test, the extract significantly (p<0.05) decreased writhing at 400 mg/kg only. Reaction times were not significantly different from the control in the hot plate and tail flick tests. Conclusion: This study has shown that the methanol extract possesses acute anti-inflammatory and peripherally mediated analgesic effects.

    Opis:
    Recently, 1,2,3-triazoles have gained an increased attention in the field of drug discovery because several derivatives have already been marketed as medications (e.g. tazobactam, cefatrizine, rufinamide) [1, 2] and many of them appeared to be very active in diverse biological studies including plinambulin 69 currently in the last stage of the clinical trials [60]. In this review very recent investigations of antibacterial, antitubercular, antifungal, antipsychotic, antiepileptic, anti-inflammatory, hypoglycemic, anticancer and antiviral properties of 1,2,3-triazole derivatives are discussed. These studies allowed to select several compounds which were found to be more active in comparison to the already used drugs.

    Opis:
    Aronia melanocarpa E. berries are a valuable component of the healthy diet. They are extremely high in phenolics exhibiting strong antioxidant properties. However, not much information is available on the chemical composition and bioactive potential of chokeberry leaves. Therefore, the analyses of sugars and phenolics of extracts from chokeberry leaves collected from June to October were performed using spectroscopic (NMR) and chromatographic (HPLC-DAD/RI, GC-MS) methods. The leaf extracts contained a significant amount of sorbitol, especially those made of leaves collected since June to July (avg. 145.2 mg/g d.w.). The average contents of Cya-3-Gal and chlorogenic acids in the extracts were at 0.52 mg g d.w. and up to 13.1 mg/g d.w., respectively. Chokeberry leaf extracts from green and red leaves were subjected to the in vitro study on human umbilical vein endothelial cells (HUVCs). Both extracts suppressed TNF-α-induced surface expression of ICAM-1 and VCAM-1 molecules, and exhibited anti-adhesive and anti-inflammatory properties. Green and red leaves may foster a therapeutic potential in the prevention of atherosclerosis and other pathological events involving leucocyte adhesion. That is why chokeberry leaves can be considered as a promising component of functional foods owing to the high content of chlorogenic acids and sorbitol.

    Opis:
    The purpose of this study was to analyze the indolic, phenolic, and fatty acid content and antioxidant activity of garlic sprouts growing in the dark and in the daylight. The pro- or anti-inflammatory properties of the garlic sprout extract were investigated by evaluating the cyclooxygenase-2 (COX-2), prostaglandin E synthase (cPGES), glutathione S transferase (GSTM1), nuclear factor NF-κB, peroxisome proliferator-activated receptors (PPARs), and aryl hydrocarbon receptor (AhR) protein levels in the RAW 264.7 cells activated with lipopolysaccharide (LPS). The highest amount of total indolic (73.56 mg/100 g f.w.) and phenolic compounds (36.23 mg/100 g f.w.) was detected in garlic sprouts grown in the daylight. Studies on antioxidant activity (the FRAP and DPPH method) of garlic sprouts showed that this activity is significantly higher for sprouts grown in full access to light when compared to those grown in the dark. In garlic sprout extracts, α-linolenic acid (ALA) was found to be in greater amount. COX-2 and cPGES level was lower when compared to LPS alone activated cells. After garlic extract treatment, higher level of GSTM1, PPARΥ, cytosolic p50 and p65 protein, as well as a lower NF-ĸB p50/p65 activity was noted in the RAW 264.7 cells which suggested PPARs and AhR transrepression mechanism of NF-ĸB signalling. The obtained results indicate Allium sativum sprouts are a rich source of n-3 fatty acids, indolic and phenolic compounds characterized by anti-inflammatory and antioxidative activity, which may support their high therapeutic and dietary potential.

    Opis:
    Analgesic and anti-inflammatory activities of four transition metal complexes of a Schiff base derived from salicylaldehyde and glycine, viz. [N-salicylideneglycinato diaqua cobalt(II) dimer] (SGCo)2, [N-salicylideneglycinato-di-aqua-nickel(ll)dimer] (SGN)2, [N-salicylideneglycinato-aqua-copper(II)] (SGC) and [N-salicylideneglycinato diaqua zinc(II) dimer] (SGZ)2 were studied in swiss albino mice. 10 mg/kg (p.o) dose for each compound were selected throughout the research work. The analgesic activity was determined by acetic acid induced writhing and tail immersion methods. All such data were compared with standard drugs at the dose of 10 mg/kg (p.o. The anti-inflammatory activity of the test compounds was determined by the carragenan induced mice paw edema inhibition method.). Analgesic and anti-inflammatory activities of the test compounds at 10 mg/kg (p.o.) were quite comparable to those of standard drugs at 10 mg/kg (p.o.). All these compounds can be considered as potent analgesic and anti-inflammatory agents.
