Boiss., A. lepidotum Boiss., A. maritimum (L.) Lam. (now syn. of Lobularia maritima (L.) Desv.) and A. simplex Rudolph. and eight accessions were studied. Th Read More

Background: Calendula arvensis is an annual Mediterranean plant growing in Morocco between Rabat and Khemissat. C. arvensisis is known in folk medicine as an anti-inflammatory and antipyretic remedy. However, few reports have investigated its pharmacological properties. Methods: The objective of the present study was to determine chemical composition of C. arvensis flowers, and to investigate their antidiabetic activiti Read More

Background: Paracetamol (p-aminophenol) and salicylates are nonsteroidal antiinflammatory drugs that are widely used in the general population. The adverse effects of both drugs continue to be a focus of the pharmaceutical industry in the development of new molecules that will increase treatment safety. In this context, we tested nine compounds derived from paracetamol and salicylates, synthesized in our laboratory, fo Read More

Background: Vietnam currently imports up to 90% of the pharmaceuticals it consumes and 100% of the steroid-based pharmaceuticals. The ability for efficient chemical synthesis of the steroids could create commercial opportunities to address this issue. Synthesis of 21-acetoxypregna-1,4,9(11)- triene-17α,21-diol-3,20-dione is considered a key intermediate in the scheme of steroidal drug synthesis. Previous synthesis at Read More

Background: The main aim of the study was to evaluate the bioactive properties of ethyl acetate crude extract of Streptomyces sp. VITASP with a view to assess their therapeutic potential. Methods: The morphological, physiological and the biochemical properties of the strain Streptomyces sp. VITASP were confirmed by conventional methods. The present study evaluated the antibacterial, antioxidant and cytotoxic activities. Res Read More

Background: The antioxidant activity and the total phenolic and flavonoid contents of the derived extracts (chloroform, ethyl acetate and n-butanol) of the 70% hydroalcoholic extract of the aerial parts of Centaurea solstitialis growing in Algeria was assessed. The active extracts were selected for phytochemical investigations. Methods: The antioxidant capabilities of the extracts were assessed using 1, 1-diphenyl-2- picrylhydrazyl r Read More

Background: Rhus pentaphylla Desf. (Anacardiaceae) widely grown in Algeria, is an underutilized plant and remains poorly studied. To investigate for the first time, the chemical composition profile of essential oil and hydrosol extract; besides Total Phenolic (TPC), Flavonoid (TFC) and Condensed Tannins Contents (CTC) of fruits, leaves and roots, the fatty acid composition was assessed. The radical scavenging activity o Read More

Background: Presentlytheeffectiveness of antifolate antimalarial drugs is decreasing due to the emergence of resistant Plasmodium strains. The aim of the present study was to determine the antimalarial effect of hybrid p-bromo phenyl thiazole-triazine derivatives against 3D7 strain of Plasmodium falciparum. Methods: Seventy-fivehybrid derivativeswere designed based on the lead molecule and docking was done again Read More

Background: Ruta chalepensis is a shrub from the Mediterranean basin widely used in the traditional medicine. The plant presents an interesting composition containing alkaloids, coumarins and volatile oil. The present work aims to study the antibacterial and the cytotoxic effects of the ethanol extract, its fractions, and the alkaloid extract from the cultivated Ruta chalepensis. Methods: Extracts were tested against five b Read More

Background: Frozen yoghurt is a suitable vehicle to deliver bioactive compounds and beneficial microorganisms, and to develop new functional dairy products. Methods: Bifidobacterium bifidum was used in the manufacture of frozen yoghurt, whereas skim milk powder was substituted by Nanoparticles Coconut Flour (NCF) and Coconut Flour (CF).
