The effect of sulfhydryl compounds on sister-chromatid exchanges

Mutation Research/Genetic Toxicology, 1980
We examined the SH compounds glutathione (GSH), cysteine (CYS), cysteamine (MEA) and 2-mercaptoethanol (MET) with regard to their capacity for inducing SCEs. Whereas cysteamine and 2-mercaptoethanol increased the SCE frequency, this did not happen with glutathione and cysteine.

The Regulatory Role of Sulfhydryl Compounds in Melanogenesis

Pigment Cell Research, 1988
Since the discovery in 1967 of the phaeomelanin pathway the regulatory role of sulfhydryl compounds in epidermal melanin pigmentation has been a major focus in pigment cell research. The current state of knowledge in the field is briefly discussed, with special reference to some recent studies extending the possible targets of sulfhydryl compounds to ...

Enzymic methylation of foreign sulfhydryl compounds

Biochimica et Biophysica Acta, 1961
Abstract A new transmethylating enzyme system in mammalian tissues, catalyzing methyl transfer from S-adenosylmethionine to sulfhydryl compounds, has been studied. A series of “nonphysiological” sulfhydryl compounds (BAL, mercaptoethanol, O-methyl-mercaptoethanol, mercaptoacetic acid, β-mercaptoproprionic acid, methymercaptan and hydrogen sulfide ...

Toxicity of sulfhydryl compounds to cultured human lymphocytes

Experimental Cell Research, 1970
Abstract The toxicity of cysteine metabolites for cultured human lymphocytes decreases with proximity in the metabolic pathways to the usual organic excretory product, taurine. Polyploidy induction also roughly parallels toxicity.

In Vitro Reduction of Tetrazolium Indicators by Sulfhydryl Compounds

Stain Technology, 1954
There was considerable variation between the sulfhydryl induced in vitro reduction of the oxidation-reduction indicators (2,3,5-triphenyltetrazolium chloride, 2,3-diphenyl 5-methyl tetrazolium chloride, neotetrazolium chloride, neotetrazolium phosphate-2B, blue tetrazolium, tetrazolium violet, potassium tellurite, methylene blue, and resazurin).

Adverse effects profile of sulfhydryl compounds in man

The American Journal of Medicine, 1986
Many of the adverse reactions produced by penicillamine and other compounds with an active sulfhydryl group form a distinctive pattern when viewed as a class. Alterations in taste perception, mucocutaneous lesions, proteinuria due to immune-complex membranous glomerulopathy, and pemphigus are adverse reactions that have been encountered with all of the

[Effect of sulfhydryl compounds on the automatism of the pacemakers].

Biulleten' eksperimental'noi biologii i meditsiny, 1977
Experiments were performed on the isolated rabbit hearts and also on the hearts with complete atrioventricular block; a study was made of the effect of an excess or deficiency of the sulfhydryl groups on the automatism of the cardiac pace makers. Unithiol and cysteine in concentrations of 1-10(-6)-1-10(-4) g/ml were used as donors of sulfhydryl groups;
