Thiols as myeloperoxidase-oxidase substrates.

B E Svensson

The Biochemical journal, 253(2), 441-449 (1988-07-15)

Nine low-Mr thiols were compared with regard to their ability to function as myeloperoxidase-oxidase substrates under conditions where no auto-oxidation of the thiols could be observed. The methyl and ethyl esters of cysteine were found to be about twice as

Kinetics and mechanistic studies of the hydrolysis of diisocyanate-derived bis-thiocarbamates of cysteine methyl ester.

Itai Chipinda et al.

Chemical research in toxicology, 19(3), 341-350 (2006-03-21)

Diisocyanates (dNCOs) are the most commonly reported cause of chemically induced occupational asthma, but the ultimate antigenic form is unknown. Reactions of the three most common monomeric dNCOs, hexamethylene dNCO (HDI), methylene diphenylisocyanate (MDI), and toluene dNCO (TDI), with cysteine

Reaction of trifluoroacetaldehyde with amino acids, nucleotides, lipid nucleophiles, and their analogs.

H Yin et al.

Chemical research in toxicology, 9(1), 140-146 (1996-01-01)

Trihaloacetaldehydes are used as sedatives, are key intermediates in the metabolism of 1,1,1,2-tetrahaloethanes, some of which are chlorofluorocarbon substitutes, and are metabolites of trihaloethanols, which are intestinal and bone marrow toxins. In the present study, trifluoroacetaldehyde was used as a
