Mechanism study of the thiol-addition reaction to benzothiazole derivative for sensing endogenous thiols
We kinetically studied the reaction between endogenous thiols such as -c-glutamylcysteine (c-Glu-Cys), cysteine (Cys), glutathione (GSH), homocysteine (Hcy), cysteinylglycine (Cys-Gly), and dihydrolipoic acid (DHLA)- ...
The influence of non-protein thiols on DNA damage induced by bleomycin in single human cells
(Begell House, 2016-03)
Nonprotein thiols are considered radioprotectors, preventing DNA damage by ionizing radiation. Because bleomycin (BLM) is a radiomimetic agent, it was proposed that thiols may prevent DNA damage produced by this antibiotic. ...
Thermal degradation of visible-light-cured thiol-methacrylate networks photoactivated with camphorquinone
This report describes the yellowing of visible light-cured thiol-ene networks formulated with Camphorquinone (CQ) as photoactivator. CQ displays an intense dark yellow color due to the presence of a conjugated diketone ...
Effect of thiol compounds on bleomycin-induced DNA and chromosome damage in human cells
(Heldref Publications, 2013-02)
Non-protein thiols are considered radioprotectors, preventing DNA damage by ionizing radiation. As bleomycin (BLM) is a radiomimetic agent it was proposed that thiols may prevent DNA damage produced by this antibiotic. ...
Chemisorption on thiol-silicas: Divalent cations as a function of pH and primary amines on thiol-mercury adsorbed

Thiol oxidation by nitrosative stress: Cellular localization in human spermatozoa
(Informa Healthcare, 2016-09)
Peroxynitrite is a highly reactive nitrogen species and when it is generated at high levels it causes nitrosative stress, an important cause of impaired sperm function. High levels of peroxynitrite have been shown to ...
Thiol-independent activity of a cholesterol-binding enterohemolysin produced by enteropathogenic Escherichia coli

Effect of three non-protein thiols on CHO cells exposed to low doses of X-radiation
The goals of this study were to determine whether cysteamine, β-mercaptohetanol and glutathione protect CHO K1 cells against chromosomal aberrations induced by low doses of X-radiation, as well as whether radiation protection ...
Study of copper complexes absorbed on a silica gel surface chemically modified with 5-amino-1,3,4-thiadiazole-2-thiol
(Academic Press Inc., 1998-10-01)
The isotherms of adsorption of CuX2 (XCl-, Br-, ClO4-) by silica gel chemically modified with 5-amino-1,3,4-thiadiazole-2-thiol were studied in acetone and ethanol solutions, at 25 degrees C. The following equilibria ...
Comparative Study of the Adsorption of Thiols and Selenols on Au(111) and Au(100)
(American Chemical Society, 2017-12)
The effect of the Au crystalline plane on the adsorption of different thiols and selenols is studied via reductive desorption (RD) and X-ray photoelectron spectroscopy (XPS) measurements. Self-assembled monolayers (SAMs) ...
