In the crystal structure of the title compound, [Zn(C(5)H(4)NO(4)S)(2)(H(2)O)(2)], the 4-oxo-1,4-dihydro-pyridine-3-sulfonate anion chelates to water-coordinated zinc centres through the carbonyl O atom and through one O atom of the sulfonate group. The Zn(II) atom lies on a center of inversion, and adjacent mol-ecules are linked by N-H⋯O and O-H⋯O hydrogen bonds, forming a three-dimensional ne...
In the crystal structure of the title compound, [Mg(H(2)O)(6)](C(7)H(5)O(6)S)(2)·2H(2)O, the octa-hedral complex cation lies on an inversion centre and is hydrogen bonded through the coordinated water molecules to the substituted benzene-sulfonate monoanions and the water mol-ecules of solvation. These inter-actions together with a carb-oxy-lic acid O-H⋯O(sulfonate) association give a three-dim...
In the title p-toluene-sulfonate salt of the drug dapsone, C12H13N2O2S(+)·C7H7O3S(-), the dihedral angle between the two aromatic rings of the dapsone monocation is 70.19 (17)° and those between these rings and that of the p-toluene-sulfonate anion are 72.34 (17) and 46.43 (17)°. All amine and aminium H atoms are involved in inter-molecular N-H⋯O hydrogen-bonding associations with sulfonyl O-at...
In the mol-ecule of the zwitterionic title compound, C(10)H(9)NO(3)S, an intra-molecular N-H⋯O hydrogen bond results in the formation of an almost planar six-membered ring (r.m.s daviation = 0.0150 Å), which is oriented at a dihedral angle of 1.63 (3)° with respect to the naphthalene ring system. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into a two-dimen...
This investigation was undertaken in view of the interest lately aroused in the association of plasma lipids with atherosclerosis. Observations on the antilipemic and anticoagulant activities in man of sodium polyethylene sulfonate, a new drug with heparin-like properties, are presented. Alteration of the serum lipoprotein patterns of these patients observed during the course of the drug admini...
OBJECTIVE Although petroleum products are useful chemical compounds which form an integral part of our modern technology, they have been reported to cause deleterious effect on health following their inhalation. Petroleum hydrocarbons-dependent health hazards and their mechanisms have been associated with the routes of administration. This study, therefore, aimed at the isolation and chemical c...
Electrospun non-woven poly(ε-caprolactone) (PCL) microfiber meshes are described as biodegradable, mechanically robust, and reusable polymeric oil sorbents capable of selectively retrieving oil from simulated oil spills in both fresh and seawater scenarios. Hydrophobic PCL meshes have >99.5% (oil over water) oil selectivity and oil absorption capacities of ~10 grams of oil per gram of sorbent m...
Occurrence of perfluorooctane sulfonate (PFOS) in the tissues of humans and wildlife is well documented. In this study, concentrations and distribution of PFOS, perfluorohexane sulfonate (PFHS), and perfluorobutane sulfonate (PFBS) were determined in samples of surface water, fish and bird blood and livers, and human blood collected in Japan. Notable concentrations of PFOS were found in surface...
