Preparation of sulfate esters. the synthesis of steroid sulfates by a dicyclohexylcarbodiimide-mediated sulfation

Steroids, 1969
Abstract Steroid sulfates were synthesized in good yield under mild conditions by a dicyclohexylcarbodiimide-mediated sulfation. The reaction is especially suitable for the synthesis of 35-labeled steroid sulfates owing to the readily available and reasonably priced 35SO4=.

Sulfates-based nanothermites: an expanding horizon for metastable interstitial composites.

Angewandte Chemie, 2015
Metal sulfates (Ba, Bi, Ca, Cu, Mg, Mn, Na, Zn, Zr) were used as oxidizers in reactive compositions with Al nanopowder. These new kinds of nanothermites have outstandingly high reaction heats (4-6 kJ g(-1) ) compared to conventional Al/metal oxides (1.5 ...

Sulfation in Dog

Current Drug Metabolism, 2005
Sulfation has been thoroughly studied in several species including e.g. man and rat. However, one important species often used for pharmacological drug studies is the dog. Here we describe recent advances as well as older data in the field of dog sulfation. Species differences in sulfation have been reported.

Tinkering with heparan sulfate sulfation to steer development

Trends in Cell Biology, 2007
Heparan sulfate (HS) proteoglycans, at the cell surface and extracellular matrix, facilitate ligand-receptor interactions crucial to many physiological processes. The distinct sulfation patterns of HS sugar chains presented by their protein core are key to HS proteoglycan activity. Tight regulation of several Golgi complex enzyme families is crucial to

Dermatan sulfate and chondroitin 6-sulfate conformations

Biochemical and Biophysical Research Communications, 1973
Abstract X-ray diffraction patterns show that dermatan sulfate in oriented, crystalline films occurs as two or three or eight-fold helices. The two-fold helix has a greater axial rise per disaccharide residue [ h = 9.6 A ] than the corresponding chondroitin 6-sulfate helix [ h = 9.3 A ] .

Sulfation of Polysaccharides using Monomethyl Sulfate

Journal of Carbohydrate Chemistry, 2000
ABSTRACT The polysaccharides, curdlan, starch and dextran were sulfated when heated in DMSO with sodium methyl sulfate and a catalytic amount of H2SO4 or with pyridinium methyl sulfate. Use of diminished pressure and anhydrous CaSO4 as a desiccant improved the degree of sulfation and recovery.

Atomistic simulations of micellization of sodium hexyl, heptyl, octyl, and nonyl sulfates.

Journal of Physical Chemistry B, 2012
Molecular dynamics simulations have been used to study the micellization behavior of atomistic models for sodium alkyl sulfates in explicit water.

Physiochemical properties of alkylaminium sulfates: hygroscopicity, thermostability, and density.

Environmental Science and Technology, 2012
Although heterogeneous interaction of amines has been recently shown to play an important role in the formation and growth of atmospheric aerosols, little information is available on the physicochemical properties of aminium sulfates.

The anticoagulant effect of heparan sulfate and dermatan sulfate

Thrombosis Research, 1976
Abstract The potency of the various glycosaminoglycans (GAGs) as anticoagulants in the activated partial thromboplastin time (APTT) test system has been investigated. Heparin, heparan sulfate (HS) and dermatan sulfate (DS) exhibit anticoagulant effect.

Chondroitin 4-sulfate: The structure of a sulfated glycosaminoglycan

Journal of Molecular Biology, 1978
Abstract The molecular conformation and crystal structure of a regular 3-fold helical form of chondroitin 4-sulfate have been refined by a process in which agreement between observed and calculated intensities is optimized, while non-bonded interactions are restrained simultaneously to reasonable values.
