There are two independent mol-ecules in the asymmetric unit of the title compound, C24H22N2O4S3. In each, the sulfonamide N atoms reveal nearly a trigonal-planar geometry with two S atoms of the O=S=O groups and one C atom of the thia-zole ring; the angles around the N atoms are between 117.00 (13) and 123.86 (9)°. The methyl-phenyl-sulfonyl groups are in anti conformations, forming dihedral an...

cellulose was modified by polystyrene (ps) and polyacrylonitrile (pan) via free radical and living radical polymerization, and then cellulose was used as the matrix in the preparation of polymer/clay nanocomposite, through a solution intercalation method. for this purpose, first, the graft polymerization of styrene (st) onto cellulose fibers was performed by using suspension polymerization and ...

Crystal structures of two N-(ar-yl)aryl-sulfonamides, namely, 4-meth-oxy-N-(4-methyl-phen-yl)benzene-sulfonamide, C14H15NO3S, (I), and N-(4-fluoro-phen-yl)-4-meth-oxy-benzene-sulfonamide, C13H12FNO3S, (II), were determined and analyzed. In (I), the benzene-sulfonamide ring is disordered over two orientations, in a 0.516 (7):0.484 (7) ratio, which are inclined to each other at 28.0 (1)°. In (I),...

The novel water-soluble N-methyl-D-aspartate (NMDA) receptor antagonists, N-{4-[4-(4-Guanidinobutylamino)butylamino]butyl}-p-toluenesulfonamide trihydrochloride (1a, TsHSPMG), N-{4-[4-(4-Guanidinobutylamino)butylamino]butyl}butane-1-sulfonamide trihydrochloride (1b, BsHSPMG), N-{3-[4-(3-Guanidinopropylamino)butylamino]propyl}-p-toluenesulfonamide trihydrochroride (2a, TsSPMG) and N-{3-[4-(3-Gua...

the aim of this study was to evaluate the ability of 15 serotypes of salmonella to form biofilm on polystyrene, polyvinyl chloride (pvc) and glass surfaces. .initially slime production was assessed on cra agar and hydrophobicity of 20 salmonella strains isolated from poultry and human and two salmonella enterica serovar typhimurium references strains was achieved by microbial adhesion to n-hexa...
