| Abstract: | The redox potential of the active Fe(III) complex of bleomycin (BLM), which is a DNA cleaving species, was measured by cyclic voltammetry at 25 °C under a hydrogen atmosphere. The cyclic voltammogram showed the reversible one-electron Fe(III)/Fe(II) coupled redox reaction at −0.225 V versus SCE. Under the same conditions the redox potentials of the iso-BLM—Fe(III) complex and the deglyco-BLM—Fe(III) complex were also observed, but the cyclic voltammogram for the inactive Fe(III) complex of BLM could not be obtained. |
