Transfer of ferritin‐bound iron to adriamycin

Abstract

Interactions of adriamycin with ferritin-bound iron have been investigated. It is demonstrated (i) that adriamycin stimulates an iron-dependent lipid peroxidation in submitochondrial particles in the presence of ferritin, and (ii) that incubation of adriamycin with ferritin results in a slow transfer of iron to adriamycin with formation of an adriamycin-iron complex. The results are discussed in relation to the possible role for intracellular iron in adriamycin toxicity.
