Résumé: A convenient method for the synthesis of new series of N-acylsulfonamide containing oxazolidin-2-one moiety starting from chlorosulfonyl isocyanate and chiral oxazolidinones in two steps (carbamoylation and sulfamoylation), is described. The starting oxazolidinones were obtained in two steps starting from amino acids by reduction with NaBH4 then cyclization in the presence of carbonate diethyl. The synthesis of N-acylsulfonamide oxazolidin-2-ones derivatives has been carried out in excellent isolated yields. The structures of all synthesized compounds were unambiguously confirmed by usual spectroscopic methods 1H NMR, 13C NMR, IR, EA and MS.

(2015), Fungitoxic Evaluation of New Modified Amidophosphonates (AP1, AP2) on the in vitro Growth of Two Fun. Research Journal of Environmental Toxicology

Résumé: We performed this work to highlight the in vitro antifungal properties of two amidophosphonates newly synthesized (AP1, AP2). These molecules were synthesized from amino esters and chloroacetyl chloride in two steps using the Michaelis-Arbuzov reaction. We have selected after testing several concentrations 15, 20 and 25 μM for AP1, 10, 25, 40 μM for AP2. The study of the antifungal power by solid medium-diffusion method was performed after microscopic study and purification of fungal isolates from wheat leaves hard, give us the opportunity to identify two fungi: Septoria tritici and Aalternaria tenuis. Results show an antifungal power of two molecules, the growth inhibition-percentage is higher among Aalternaria tenuis. In addition, AP2 molecule appears to have a stronger antifungal activity. Determining the Minimum Inhibitory Concentration (MIC) by the dilution method in liquid medium, shapeless on the effectiveness of our molecules which is to order of 40 μM (AP1) and 25 μM (AP2) for Septoria tritici, 25 μM (AP1) and 15 μM (AP2) for Alternaria tenuis.

Résumé: This study aims to evaluate, in vitro, antibacterial activity of four novel sulfonamide derivatives (1a-d) against Staphylococcus aureus: reference strain ATCC 25923 and 40 clinical isolates. Inhibition zones were performed with the disk diffusion method. The MIC values were determined by the dilution broth method. A 48 hours MIC-Kinetic curve was performed for the tested compounds. All compounds showed significant antibacterial activity. The mean values of the inhibition zones diameter for compounds 1a-d were 22.15 ± 6.22, 16.39 ± 1.17, 15.42 ± 0.66 and 15.83± 1.28 mm, respectively (p value = 0.001). The MIC values were ranged between 64 and 512 g/ml. The compound 1b showed better activity. The 48 hours MIC-kinetic curve showed an inhibiting bacterial growth. The studied compounds 1a-d showed a promising antibacterial effect to response to the urgent need for innovative drugs that could be more effective against resistant pathogens.

(2014), In-vitro Antibacterial Activity of two Novel Sulfonamide Derivatives against Urinary Strains of Esch. Research Journal of Pharmaceutical, Biological and Chemical Sciences

Résumé: Two novel sulfonamide derivatives, the 3,4-dihydroisoquinoline-2(1H)-sulfonamide (1a) and the 4phenylpeperazine sulphonamide (1b), have been evaluated in vitro as antibacterial agents against urinary and standard strains of Gram-negative Escherichia coli, by both disk diffusion and dilution assay methods. These bacteria were screened against the novel compounds which were compared to a standard antibiotic, the sulfamethoxazol-trimethoprim (STX). The results revealed that the tested compounds showed a good antibacterial activity. The diameters of the growth inhibition area were in the range 10-40 mm. Antibacterial activity of compound 1a, against all the bacterial strains, was superior to those of the compound 1b and the commercial drug SXT. The diameters of the growth inhibition area of sulfonamide 1a were in the range 15-40 mm and the MICs were ranged from 2 to 128 g/ml. Compound 1b was less active than compound 1a but more active than antibiotic SXT. Diameters of inhibition of compound 1b were in the range 4-26 mm and the MICs were ranged from 8 to 256 µg/ml. In conclusion, the newly synthesized sulfonamide derivatives showed a powerful interesting antibacterial activity against all strains of Escherichia coli. Better activity was obtained with compound 1a. In-vitro Antibacterial Activity of two Novel Sulfonamide Derivatives against Urinary Strains of Escherichia coli..
