Abstract

Parkinson's disease (PD) is a neurological disorder characterized by the progressive impairment of motor skills in patients. Growing evidence suggests that abnormal redox-active metal accumulation, caused by dysregulation, plays a central role in the neuropathology of PD. Redox-active metals (e.g. Fe and Cu) catalyze essential reactions for brain function. However, these metals can also participate in the generation of highly toxic free radicals that can cause oxidative damage to cells and ultimately lead to the death of dopamine-containing neurons. The emergence of redox-active metals as key players in the pathogenesis of PD strongly suggests that metal-chelators could be beneficial in the treatment of this condition. This mini-review summarizes major recent developments on natural, synthetic iron chelating compounds and hydrogen peroxide-triggered prochelators as potential candidates for PD treatment.
