Different iron(II) complexes of bleomycin A2.
By 13C-nmr on iron-bleomycin preparations, an iron-bleomycin-CO complex is found that loses its CO upon standing, as demonstrated using 14CO. Iron-bleomycin, prepared without rigorous exclusion of oxygen, reacts with CO to a stable diamagnetic iron-bleomycin-CO complex.
