Oxidized metabolites of dopamine, known as dopamine quinone derivatives, are thought to play a pivotal role in the degeneration of dopaminergic neurons. Although such quinone derivatives are usually produced via the autoxidation of catecholamines, tyrosinase, which is a key enzyme

Apoptosis was induced in human foreskin fibroblasts by the redox-cycling quinone naphthazarin (5,8-dihydroxy-1,4-naphthoquinone). Most of the cells displayed ultrastructure typical of apoptosis after 8 h of exposure to naphthazarin. Apoptosis was inhibited in fibroblasts pretreated with the cathepsin D inhibitor
