Without doubt, natural products have been, and still are, the cornerstone of the health care armamentarium. Of all natural sources, the marine environment is clearly the last great frontier for pharmaceutical and medical research. This work progresses in the direction of identifying component(s) from the Mediterranean sponge, Spongia officinalis with(More)
Seaweeds have caused an emerging interest in the biomedical area, mainly due to their contents of bioactive substances which show great potential as anti-inflammatory, anti-microbial, anti-viral and anti-tumoral drugs. Despite the diversity in quality and quantity of the Mediterranean Tunisian coast flora, with its large contains of marine organisms and(More)
Olea europaea L. is used in traditional medicine in the Mediterranean areas. Its natural products are used in the treatment of different disorders, like fighting fever and some infectious diseases such as malaria, the treatment of arrhythmia, and relief of intestinal spasms. The aim of the current study is to investigate the possible anti-inflammatory and(More)
Seaweed polysaccharides are highly active natural substances having valuable applications. The present study was conducted to characterize the physico-chemical properties of sulphated polysaccharides from three Mediterranean brown seaweeds (Cystoseira sedoides, Cystoseira compressa and Cystoseira crinita) and to evaluate their anti-radical,(More)
This study progresses in the direction of identifying component(s) from the Mediterranean sponge, Spongia officinalis with anticonvulsant and analgesic activities. We investigated the efficacy of crude extract and its semi-purified fractions (F1-F3) of the defensive secretion from Spongia officinalis for their in vivo anticonvulsant activity using the(More)
A series of new chiral fluorine-containing β-hydroxysulfonamides were conveniently synthesized in three steps, starting from natural L-amino acids, and evaluated for their anti-inflammatory and analgesic activities. The structures of these compounds were supported by FT-IR, 1H, 13C and 19F NMR, elemental analysis and HRMS. Among the tested compounds, 4c, 4g(More)
Dictyopteris membranacea, a species of Mediterranean brown algae, is believed to have potential pharmacological and nutritional applications. However, such potentials only make sense when devoid of any adverse health consequences. The present study should be seen in this context. It aimed at evaluating the genotoxicity and cytoxicity of its organic extract(More)
Gorgonians of the genus Eunicella are known for possessing a wide range of pharmacological activities such as antiproliferative and antibacterial effect. The aim of this study was to evaluate the anti-inflammatory and gastroprotective effect of the organic extract and its semi-purified fractions from the white gorgonian Eunicella singularis and the(More)
We report the synthesis of new anti-inflammatory 1,7-dihydropyrazolo[3′,4′:4,5]pyrimido[1,6-a]pyrimidine 5 from aminocyanopyrazole. All compounds were characterized by physical, chemical and spectral studies. Preliminary pharmacological evaluation of the resulting products showed that compounds 5a, b, f (50–100 mg/kg, i.p) are active anti-inflammatory(More)
Current study was designed to explore the analgesic and the anti-inflammatory activities of a new cucurbitacin isolated from Tunisian Citrullus colocynthis Schrad. seeds. 11-Deoxocucurbitacin-I-2-O-β-d-glucoside was isolated from C. colocynthis seed chloroform fraction. This organic fraction, one of its subfraction (F19), and the purified(More)
