Synthesis and mutagenic properties of 4,4'-diamino-p-terphenyl and 4,4'-diamino-p-quaterphenyl / Jinlong Wang in COLORATION TECHNOLOGY, Vol. 123, N° 1 (2007)  

[article]  inCOLORATION TECHNOLOGY > Vol. 123, N° 1 (2007) . - p. 34-38 Titre : Synthesis and mutagenic properties of 4,4'-diamino-p-terphenyl and 4,4'-diamino-p-quaterphenyl Type de document : texte imprimé Auteurs : Jinlong Wang, Auteur ; Harold S. Freeman, Auteur ; Larry D. Claxton, Auteur Année de publication : 2007 Article en page(s) : p. 34-38 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : 4,4'-Diamino-p-terphenyl and 4,4'-diamino-p-quaterphenyl were synthesised from readily available chemical intermediates. These compounds, along with 1,4-diaminophenylene and benzidine were examined in the Salmonella microsome assay with strains TA98 and TA100. The results of this study indicate that the mutagenicity of these diamines was the greatest for 4,4'-diamino-p-terphenyl, followed by diaminophenylene and benzidine, with 4,4'-diamino-p-quaterphenyl showing no mutagenicity.

Synthesis and mutagenic properties of direct dyes from 4,4'-diamino-p-terphenyl and 4,4'-diamino-p-quaterphenyl / Jinlong Wang in COLORATION TECHNOLOGY, Vol. 123, N° 1 (2007)

Langues : Anglais (eng) Index. décimale : 667.3 Teinture et impression des tissus Résumé : Disazo direct dyes were synthesised using bis-diazotisation and coupling reactions involving 4,4'-diamino-p-terphenyl and 4,4'-diamino-p-quaterphenyl. The formation of the target dyes was confirmed by electrospray mass spectrometry and their mutagenicity was examined in the Salmonella microsome assay using TA98 and TA100. While most of these dyes were clearly non-mutagenic, results from the Prival modification of the standard assay showed that Congo Red and its homologue derived from 4,4'-diamino-p-terphenyl were clearly mutagenic.
