Mutagenicity of 4-nitrodiphenyl ether and its metabolites.
The mutagenic potential of 4-nitrodiphenyl ether (NDE) an intermediate of herbicides and an anthelmintic drug, and its reduced products (-NO, -NHOH) were investigated in the Ames test. All the three compounds were potent direct-acting base-pair and frameshift mutagens with activity order -NHOH greater than -NO greater than -NO2. The -NHOH compound has been considered to be the penultimate/ultimate mutagen.
