Recent Research with Some Sulfur-Containing Chelating Agents

Some nitrogen and sulfur containing compounds as chemotherapeutic agents.

Perspective on recent developments on sulfur-containing agents and hydrogen sulfide signaling.

The last couple of years have witnessed the coming together of several initially unconnected lines of investigation which now link natural sulfur products to hydrogen sulfide release and wide ranging cardiovascular protection. It has become apparent that sulfur compounds contained within garlic, onions, mushrooms and various edible beans and fruits may be transformed chemically or enzymatically...

Chromatographic Separations with Selected Supported Chelating Agents

Effects of some sulfur-containing antioxidants on lead-exposed lenses.

Lead (Pb) is known to negatively affect glutathione (GSH) metabolism in the lens. The present study examined the effects of Captopril, Taurine, and alpha-Lipoic acid on the Pb-induced GSH depletion and lipid peroxide increase in the lenticular system. Captopril administration returned the GSH, cysteine (CYS), and malondialdehyde (MDA) levels to near normal. Following Taurine administration the ...

Oxidation of Some Biologially Active and Related Sulfur Containing Compounds

Earlier works on oxidation of sulf ides, thiols, and disulf ides with both chemical and enzymic systems are reviewed. Enzymic oxidations of thiols and disulfides are compared with their chemical oxidations with N2O and H2O2 by the use of unsymmetrical disulf ides, thiolsulfinates and O18_ tracer technique. In both enzymic oxidation and that with N2O, oxidation of disulfides to thiolsulfinates i...
