Nitrosation products from S-nitrosothiols via preliminary nitric oxide formation

Autor: Darren R. Noble, D. Lyn H. Williams

Publikováno v: Journal of the Chemical Society, Perkin Transactions 2. :1834-1838

High yields of N-nitroso-N-methylaniline were obtained from S-nitrosothiols (RSNO) and N-methylaniline in water at pH 7.4. Reactions were completely inhibited by the presence of EDTA and also when oxygen was removed from the solutions. Lower yields o

Formation and reactions of S-nitroso proteins

Autor: Darren R. Noble, D. Lyn H. Williams

Publikováno v: Journal of the Chemical Society, Perkin Transactions 2. :13-17

Nitrosation of Bovine Serum Albumin (BSA) by nitrous acid occurs in two stages: a rapid step, which is consistent with an S-nitrosation reaction of a free cysteine unit, followed by a slower reaction which is consistent with an N-nitrosation reaction

Nitrosation of anisole, stability constants of complexes of the nitrosonium ion with aromatic nitroso compounds, and NMR studies of restricted rotation in the complexes

Autor: John H. Atherton, Roy B. Moodie, Darren R. Noble

Publikováno v: Journal of the Chemical Society, Perkin Transactions 2. :229-234

Anisole can be nitrosated in good yield under the acidic and anaerobic conditions previously reported for methylbenzenes. The product, 4-nitrosoanisole, is slowly converted into 4-nitrosophenol in acetic–sulfuric acid mixtures. The decrease in the

Kinetics and mechanism of nitrosation of toluene, o-xylene, and m-xylene in trifluoroacetic acid, or in acetic–sulfuric acid mixtures, under nitric oxide

Autor: John H. Atherton, Roy B. Moodie, Darren R. Noble

Publikováno v: Journal of the Chemical Society, Perkin Transactions 2. :699-706

The title reactions give good yields with m-xylene, and modest yields with toluene and o-xylene which are successfully directly nitrosated for the first time. The advantages of purging with nitric oxide are demonstrated and discussed. The kinetics ha

ChemInform Abstract: Nitrosation of m-Xylene, Anisole, 4-Nitrophenyl Phenyl Ether and Toluene in Trifluoroacetic Acid or in Acetic-Sulfuric Acid Mixtures under Nitric Oxide

Autor: Brian O'Sullivan, Darren R. Noble, Roy B. Moodie, John H. Atherton

Publikováno v: ChemInform. 28

Nitrosation in trifluoroacetic acid or in acetic–sulfuric acid mixtures is regioselective and accompanying non-selective nitrous acid catalysed nitration can be avoided by purging with nitric oxide.

Nitric oxide release from S-nitrosoglutathione (GSNO)

Autor: Darren R. Noble, D. Lyn H. Williams, Helen R. Swift

Publikováno v: Chemical Communications. :2317-2318

In the presence of Cu2+ (10–5 M) very little NO is generated from GSNO at ≡10–3 M at pH 7.4, whereas the reaction is quantitative at ≡10–6 M; this is explicable in terms of the complexation of Cu2+ by the product GSSG.
