Methapyrilene: DNA as a possible target.

The structural features contributing to the potential carcinogenicity, DNA-reactivity and genotoxicity of methapyrilene and its non-carcinogenic congener pyrilamine were examined. The analyses suggest that the former has the potential for DNA-reactivity, a property which is absent from the latter.
