Oxidants, nitrosants, and the lung
The American Journal of Medicine, 2000The respiratory tract is subjected to a variety of environmental stresses, including oxidizing gases, particulates, and airborne microorganisms, that together, may injure structural and functional lung components and thereby jeopardize the primary lung function of gas exchange.

Genotoxicity of nitrosated ranitidine
Mutation Research Letters, 1989The genotoxicity of ranitidine, widely used in the therapy of peptic ulcers, and of nitrosated ranitidine was examined in test systems with the bacteria Salmonella typhimurium for gene mutations, and with the yeast Saccharomyces cerevisiae D7 for reverse mutations and gene conversion.

Detection of Nitrosated Proteins
Current Protocols in Toxicology, 1999AbstractThree methods are provided in this unit to detect nitrosated proteins. The Saville assay is the most commonly used and has the advantages that it is less sensitive to interference than the quinine sulfate‐based fluorescent assay, uses simple chemical reagents, and requires a spectrophotometer. The diaminonaphthalene assay (a fluorescence assay)

Nitrosative Stress and Transcription
Biological Chemistry, 2003Low NO concentrations synthesized by constitutively expressed NO synthases act on several signaling pathways activating transcription factors (TF), such as NF-kappaB or AP-1, and thereby influence gene expression. In contrast, during inflammatory reactions the inducible NO synthase produces NO for prolonged periods of time.

The nitrosation of methallylchloride
Recueil des Travaux Chimiques des Pays-Bas, 1951AbstractThe action of aqueous nitrous acid on 2‐chloromethylpropene‐1 (methallylchloride) results in the formation of an unstable addition product which is converted into 1‐chloro‐2‐methyl‐3‐nitropropene‐1 upon treatment with alkali. For this new compound, the name nitro isocrotyl chloride is proposed. Its structure was established by ozonolysis, which

The kinetics of the nitrosation of the ammonia in acid solution show a first-order dependence on [NH4+] and [HNO2], and a zero-order dependence upon [H+]. Reaction is very strongly catalysed by both Br– and SCN–. These facts are consistent with a mechanism in which BrNO or ONSCN reacts with the free base form of ammonia in the rate-limiting step, to ...

AbstractThe nitrosation of nylon 66, with the use of four different nitrosating agents, has been investigated. By the more vigorous nitrosating reactions, heterogeneous nitrosation of nylon yarn occurs rapidly and proceeds to completion in a few hours.
