Micronucleus induction in mice exposed to diazoaminobenzene or its metabolites, benzene and aniline: implications for diazoaminobenzene carcinogenicity.

Nancy B Ress et al.

Mutation research, 521(1-2), 201-208 (2002-11-20)

Diazoaminobenzene (DAAB), a manufacturing intermediate metabolized primarily to the known carcinogens benzene and aniline, has been identified as an impurity in a number of dyes and coloring agents that are components of cosmetics, food products, and pharmaceuticals. Several structural analogs

Determination of 1,3-diphenyltriazene and azobenzene in D&C Red No. 33 by solvent extraction and reversed-phase high-performance liquid chromatography.

J E Bailey

Journal of chromatography, 321(1), 185-197 (1985-03-08)

Data are presented for the determination of trace levels of 1,3-diphenyltriazene (DPT) and azobenzene (AB) in D&C Red No. 33. The contaminants are extracted with chloroform from an aqueous solution of the color, and the chloroform is removed under vacuum.

Reduction of 1,3-diphenyl-1-triazene by rat hepatic microsomes, by cecal microflora, and in rats generates the phenyl radical metabolite: nn ESR spin-trapping investigation.

M B Kadiiska et al.

Chemical research in toxicology, 13(11), 1082-1086 (2000-11-23)

An ESR spin-trapping technique was used to determine whether free radical metabolites are formed as a result of the reduction of 1, 3-diphenyl-1-triazene (DPT) in vivo and in vitro by components of the cytochrome P450 (P450) mixed-function oxidase system in

A ligand-free copper (1) catalysed intramolecular N-arylation of diazoaminobenzenes in PEG-water: an expeditious protocol towards regiospecific 1-aryl benzotriazoles.

Chhanda Mukhopadhyay et al.

Organic & biomolecular chemistry, 8(20), 4720-4729 (2010-09-08)

An efficient and highly versatile method for the synthesis of diverse regiospecific 1-arylbenzotriazoles being important medicinal scaffolds, by the copper (1) catalysed intramolecular N-arylation of diazoaminobenzenes of 2-haloaryldiazonium salts in PEG-water has been developed. A very simple reaction protocol, large

Gold nanoparticles modified electrode via a mercapto-diazoaminobenzene monolayer and its development in DNA electrochemical biosensor.

Feng Li et al.

Biosensors & bioelectronics, 25(9), 2084-2088 (2010-03-09)

A novel protocol for the gold nanoparticles (AuNPs) modification on the electrode surface was proposed, which was based on the self-assembly of AuNPs on the mercapto-diazoaminobenzene monolayer modified electrode. The mercapto-diazoaminobenzene monolayer was obtained by covalent immobilization of 4-aminothiophenol (4-ATP)
