    Abstract:
    Methyl 2-(2-aminoethyl)-aminomethyl-pyridine-6-carboxyl-histidinate (AMPHIS), a synthetic analogue of the chelating part of bleomycin (BLM), has been studied for its metal binding properties. Electron spin resonance parameters of AMPHIS-Cu(II) and BLM-Cu(II) have been found to be closely similar likewise spectra of oxygen radicals spin-adducts induced by AMPHIS-Fe(II)-O2 and BLM-Fe(II)-O2 systems. Thus, AMPHIS could constitute a very useful tool for the study of BLM mode of action.
