Abstract

original image

The carcinogenicity of aromatic amines has been known since 1895. It has now been possible for the first time to convert the hydroxylamine derivative generated from 4-aminobiphenyl 1 into the crystalline title compound 2 in vitro. 2 reacts with deoxyguanosine to give the same “adducts” which, e.g., are also obtained when 1 is administered to dogs and the DNA is subsequently cleaved enzymatically (Aryl = 4-biphenylyl).
