  • Title: Demonstration of nitrogen coordination in metal--bleomycin complexes by electron spin--echo envelope spectroscopy.
    Author: Burger RM, Adler AD, Horwitz SB, Mims WB, Peisach J.
    Journal: Biochemistry; 1981 Mar 17; 20(6):1701-4. PubMed ID: 6164390.
    Abstract:
    We have studied the Cu(II), Co(II), and Fe(III) complexes of the antineoplastic drug bleomycin by using electron spin--echo envelope spectroscopy. For all three complexes, nitrogen coordination of the metal ions is demonstrated. For the Cu(II)-- and Co(II)--drug complexes, we have been able to identify imidazole as a metal ligand.
