Penaeus vannamei protease activating mechanism of sulfhydryl reducing compounds
International Journal of Biological Macromolecules, 2018For the very first time, protease enzyme from Penaeus vannamei was investigated for its activation with thiol reductant compounds. The mechanism by which sulfhydryl reductant compounds enhances the activity of P. vannamei protease still remains unclear. In this study, it was discovered that thiol-reactive compounds increase P.

The Inhibition of Metabolic Oxalate Production by Sulfhydryl Compounds
Journal of Urology, 1991A number of sulfhydryl compounds were shown to inhibit CO2 and oxalate formation from glyoxylate by rat liver homogenates and hepatocytes. The most significant inhibition occurred with cysteine and this inhibition was concentration-dependent. In rats made hyperoxaluric by administering ethylene glycol in their drinking water, daily intraperitoneal ...

Adverse effects profile of sulfhydryl compounds in man
The American Journal of Medicine, 1986Many 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

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.

Toxicity of sulfhydryl compounds to cultured human lymphocytes
Experimental Cell Research, 1970Abstract 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.

Indirect Radioprotection by Sulfhydryl Compounds: A Model Chemical System
Radiation Research, 1970It is shown that radicals produced from ethanol, formate, and methanol by OH radical attack are able to destroy the thymine chromophore, with a rate constant of the order of $10^{5}\ M^{-1}\,{\rm sec}^{-1}$ . Addition of small quantities of cysteine protects thymine almost completely.

The effect of sulfhydryl compounds on sister-chromatid exchanges
Mutation Research/Genetic Toxicology, 1980We 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.

Protection Against Radiation Induced Chromosome Injury by Sulfhydryl Compounds
Acta Radiologica: Oncology, 1985The radiation induced changes in a critically radiation-sensitive tissue, bone marrow of Swiss albino mice and its modification by two sulfhydryl compounds, MPG and WR-2721, were studied cytogenetically after whole body exposure to 0.5, 1.5, 3.0, 4.5 and 6.0 Gy of 60Co gamma radiation.

Alteration of lymphocyte response by sulfhydryl and disulfide compounds
Biochemical Pharmacology, 1979Abstract The effects on the proliferative response of human lymphocytes of the sulfhydryl agents d -penicillamine and 5-thiopyridoxine, some analogues of these agents, and their respective disulfides were investigated. The sulfhydryl agents inhibited the proliferation of mitogen-stimulated lymphocytes and suppressed the mixed lymphocyte reaction ...
