Measurement of homocysteine and other aminothiols in plasma: advantages of using tris(2-carboxyethyl)phosphine as reductant compared with tri-n-butylphosphine.

J Krijt et al.

Clinical chemistry, 47(10), 1821-1828 (2001-09-25)

Aminothiols have been implicated in the pathogenesis of arteriosclerosis, and reliable methods are needed to determine their concentrations in body fluids. We present a comparison of two analytical methods and focus on the reduction of low-molecular weight and protein-mixed disulfides

Tributylphosphine-catalyzed cycloaddition of aziridines with carbon disulfide and isothiocyanate.

Jing-Yu Wu et al.

The Journal of organic chemistry, 73(22), 9137-9139 (2008-10-24)

Aziridines underwent cyclization reaction with carbon disulfide and isothiocyanate in the presence of organophosphine to afford thiazolidinone derivatives in good to high yields. The mechanistic study revealed that organophosphine serves as a catalyst in the reaction.

Identification and quantitation of cysteine in proteins separated by gel electrophoresis.

J X Yan et al.

Journal of chromatography. A, 813(1), 187-200 (1998-08-11)

A simple technique is introduced to identify and quantitate cysteine (Cys) after acid hydrolysis of protein. The technique involves using 9-fluorenylmethyl chloroformate (Fmoc)-based amino acid analysis that recovers all of the amino acids (asparagine and glutamine are recovered in their

The coordination chemistry of copper(I) in liquid ammonia, trialkyl and triphenyl phosphite, and tri-n-butylphosphine solution.

Kersti B Nilsson et al.

Dalton transactions (Cambridge, England : 2003), (9)(9), 1312-1319 (2004-07-15)

The coordination chemistry of the solvate complexes of the relatively soft electron-pair acceptor copper(I) has been studied in solution and solid state in seven solvents with strong electron-pair donor properties, liquid ammonia, trimethyl, triethyl, triisopropyl, tri-n-butyl and triphenyl phosphite, and

Urinary excretion measurement of cysteine and homocysteine in the form of their S-pyridinium derivatives by high-performance liquid chromatography with ultraviolet detection.

E Kaniowska et al.

Journal of chromatography. A, 798(1-2), 27-35 (1998-05-02)

Several human diseases, in particular metabolic disorders, often lead to the accumulation of characteristic metabolites in plasma, urine and cells. The selected diseases of this type include cystinuria and homocystinuria. In the typical laboratory diagnosis of these two diseases, a
