چکیده
rides consisting of six or more cr-1,4-linked Dglucopyranose units which possess primary hydroxyl groups at the C-6 positions and secondary hydroxyl groups at the C-2 and C-3 positions. Because cyclomaltooligosaccharides have a hydrophobic and optically active interior, they have been utilized as transporters of hydrophobic molecules and as small molecular mimics of enzymes. One of the cyclomaltooligosaccharides, cyclomaltooctaose, has a 1arger interior than cyclomaltohexaose and cyclomaltoheptaose, and shows such char-

Solution structures of chemoenzymatically synthesized heparin and its precursors.
We report the first chemoenzymatic synthesis of the stable isotope-enriched heparin from a uniformly labeled [(13)C,(15)N]N-acetylheparosan (-GlcA(1,4)GlcNAc-) prepared from E. coli K5. Glycosaminoglycan (GAG) precursors and heparin were formed from N-acetylheparosan by the following steps: chemical N-deacetylation and N-sulfonation leading to N-sulfoheparosan (-GlcA(1,4)GlcNS-); enzyme-catalyz...
متن کاملConformational changes and anticoagulant activity of chondroitin sulfate following its O-sulfonation.
Chondroitin sulfate from bovine tracheal cartilage, with the basic structure (4-O-sulfo-D-GalpNAc beta-1-->4-D-GlcpA)n, was chemically modified by O-sulfonation. Depending on the reaction conditions, the products showed a different degree of O-sulfonation. A fully O-sulfonated chondroitin sulfate, having no free hydroxyl groups, and a sulfo ester group:disaccharide unit ratio of 4.0 was prepare...
متن کاملSynthesis of sucrose-based surfactants through regioselective sulfonation of acylsucrose and the nucleophilic opening of a sucrose cyclic sulfate
Synthesis of a new class of anionic and amphoteric sucrose-based surfactants is described. Direct sulfonation of 6-O-acylsucrose using the pyridine±sulfur trioxide complex led to a mixture of the regioisomeric monosulfates, 6-O-acyl-40±O-sulfosucrose and 6-O-acyl-10-O-sulfosucrose, while sulfonation of 10-O-acylsucrose aorded a mixture of 10-O-acyl-60-O-sulfosucrose and 10-O-acyl-6O-sulfosucro...
متن کاملNafion-layered sulfonated polysulfone fuel cell membranes
Sulfonated polysulfone (SPSU) with high ion exchange capacity (IEC) and ion conductivity was synthesized through deep sulfonation of polysulfone using the trimethysilyl chlorosulfonate as sulfonation agent. The silicon-containing compounds formed during the synthesis of SPSU were completely removed from the SPSU by simple evaporation. Water swelling, ion exchange capacity, conductivity and fuel...
متن کاملTriclosan as a substrate and inhibitor of 3'-phosphoadenosine 5'-phosphosulfate-sulfotransferase and UDP-glucuronosyl transferase in human liver fractions.
Triclosan is a broad spectrum antibacterial agent used in many household products. Due to its structural similarity to polychlorobiphenylols, which are potent inhibitors of the sulfonation and glucuronidation of 3-hydroxy-benzo[a]pyrene, it was hypothesized that triclosan would inhibit these phase II enzymes. This study was designed to assess the interactions of triclosan as a substrate and inh...
