The present study was conducted to determine whether quantitative or qualitative changes in hepatic ferritin occur as a consequence of aging and whether diquat-mediated oxidation is intensified by elevated ferritin concentrations.

These results suggest that diquat toxicity may be associated with the release of iron from ferritin in vivo and that iron release from ferritin may be a process common to other free radical mediated toxicities.

Ferritin iron was released by a number of bipyridyl radicals including those derived from diquat and paraquat, the anthracycline radicals of adriamycin, daunorubicin and epirubicin, the semiquinones of anthraquinone-2-sulphonate, 1,5 and 2,6-dihydroxyanthraquinone, 1-hydroxyanthraquinone, purpurin, and plumbagin, and the nitroaromatic radicals of nitrofurantoin and metronidazole.

Similarly, the cation free radicals of the closely related chemicals, diquat and benzyl viologen, also promoted iron release.

SWR mice were more susceptible than C57BL/10ScSn mice to the toxic action of diquat, which is thought to involve iron catalysis.
