Voltammetric Detection of Free Sulfhydryl Compounds in Food Flours
Electroanalysis, 2007 Cyclic voltammetry has been applied to the rapid measurement of free SH-compounds in food flours samples. The protocol is based on the electrochemical adaptation of the Ellman's test, where the DTNB reacts with SH-compounds present in food flour extracts,

Electroanalysis, 2011 A new method to modify electrodes with carbon nanotubes (CNT) was developed. Multiwalled carbon nanotubes (MWNT) were adsorbed on the electrospun nylon-6 nanofibrous membranes (Ny-6-NFM) and used as a coating to modify conventional glassy carbon ...

Detoxification of urotoxic oxazaphosphorines by sulfhydryl compounds
Journal of Cancer Research and Clinical Oncology, 1981Urotoxic side effects, especially hemorrhagic cystitis, have so far been a limiting factor in the therapeutic use of cyclophosphamide (Endoxan), ifosfamide (Holoxan), and trofosfamide (Ixoten). The uroprotective agent mesna (Uromitexan) allows regional detoxification in the kidney and the urinary tract, and thus clinical prevention of the urotoxic side

Incorporation of sulfhydryl compounds into melanins in vitro
Biochimica et Biophysica Acta (BBA) - General Subjects, 1988Cysteine is known to be involved in pheomelanin synthesis. Available evidence, however, indicates that glutathione may also play an important role in melanogenesis. This in vitro study clarifies how cysteine and glutathione participate in melanogenesis.

Reaction of malformin with sulfhydryl compounds
Phytochemistry, 1970Abstract Malformin reacts with the sulfhydryl compounds, cysteine and β-mercaptoethanol, to form an insoluble 1:1 addition product. This reaction may explain the ability of thiol compounds to inhibit the activity of malformin and suggests reaction of malformin with thiol compounds in vivo .

Sulfhydryl Compounds as Thermosensitizers
1988The cytotoxic effects of a number of widely used chemotherapeutic agents have been reported to be enhanced by heat (Hahn 1979; Hahn and Li 1982). The exact mechanism of this enhancement is not fully understood and might differ with the various compounds. Thermosensitization by sulfhydryl compounds in vitro has been observed by Kapp and Hahn (1979).

In vivo depression of hepatic succinoxidase by sulfhydryl compounds
Biochemical and Biophysical Research Communications, 1971Abstract Thioglycolate injected i.v. in dosages of 50 mg/kg, significantly depressed hepatic succinoxidase in immature rats of either sex and adult males whereas, about a five-fold excess was required to elicit a significant response in adult females. Ovariectomy increased and estradiol pretreatment, decreased the sensitivity to thioglycolate.

Role of Sulfhydryls in the Hepatotoxicity of Organic and Metallic Compounds
Toxicological Sciences, 1985Endogenous sulfhydryl compounds serve a critical role in maintaining the function and viability of living systems. Glutathione (GSH) is the most abundant of these nonprotein thiols. During the past decade it has been demonstrated that sulfhydryls such as GSH also serve an important role in protecting vital nucleophilic sites in the liver from ...

Products of the reaction of selenite with intracellular sulfhydryl compounds
Biological Trace Element Research, 1991The usual first step in the intracellular metabolism of exogenous selenite is its chemical reaction with glutathione to form selenodiglutathione (1). We have investigated whether selenite also reacts intracellularly with other SH compounds. HeLa cells were exposed to [75Se]selenite and lysed with SDS.

The reduction of experimentally induced inflammation by sulfhydryl compounds
Biochemical Pharmacology, 1967Abstract The sulfhydryl compounds acetylcysteine and acetylpenicillamine were found to reduce the severity of induced dermal inflammation in rabbits when the compounds were administered in repeated doses. Treatment with acetylcysteine and salicylate given concomitantly resulted in an anti-inflammatory response which was equal to that obtained with ...
