Structure and carcinogenic activity of azo dyes.
In recent years many investigations have been carried out on the carcinogenic activity of several groups of derivatives of 4-aminoazobenzene, their spectra, the relative basicities of their nitrogen atoms, and their metabolism (1, 2, 9, 14). The principal results on the correlation of structure and activity are as follows: Methylation.--3'-Methyl-4-dimethylaminoazobenzene is a tvery potent carc...
متن کاملStudies in Carcinogenesis with Azo Compounds I. The Action of Four Azo Dyes in Mixed and Pure Strain Mice*
It has been known since 1932 (23) that 4'-amino2,3'-azotoluene will induce liver tumors in rats receiving the dye orally. Later, Kinosita (10) demonstrated the superior carcinogenic activity of an isomeric azo dye, N,N-dimethyl-p-arninoazobenzene, toward the rat liver; this superiority was revealed both in the shorter minimal feeding period and in the shorter latent period. Both these azo dyes ...
متن کاملThe Carcinogenicity of Certain Azo Dyes
Information on the relation of molecular structure to carcinogenicity is not nearly so extensive for the azo dyes as for the polycyclic hydrocarbons (10). Most of the pertinent publications appeared in Japan shortly after the carcinogenicity of azo dyes was first recognized, but before experimental conditions were established for an adequate survival of animals ingesting these compounds. One of...
متن کاملThiophene-Based Azo Dyes and Their Applications in Dyes Chemistry
The thiophene-based azo dyes class of azo dyes have generated considerable interest since its discovery 62 years ago. These dyes have come to be applied to a very large number and variety of fibres and have therefore achieved an importance which is probably greater than the weights used would suggest. The connection between dyeing and fastness properties on the one hand and chemical constitutio...
متن کاملKinetics of anaerobic biodecolourisation of azo dyes.
Kinetics of anaerobic biodecolourisation (methanogenic environment) of four azo dyes (Acid Orange 6, Acid Orange 7, Methyl Orange and Methyl Red) was investigated with regard to their electrochemical properties as well as under variation of dye and sludge concentrations, pH and temperature. Cyclic voltammetry revealed a correlation between the potential of irreversible reduction peak of the dye...
