Daunorubicin aqueous solutions were reduced by COO − free radicals produced by γ‐radiolysis. This reaction leads to 7‐deoxyaglycon daunomycinone. Added before irradiation, H 2 O 2 oxidizes hydroquinone daunorubicin giving back the drug directly and thus preventing C‐O bond cleavage. The implications of this reaction on the mechanism of the reductive cleavage are discussed.
