Defects in mitochondrial function are linked to numerous neurodegenerative diseases including Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, and Friedreich’s ataxia, and are the hallmarks of a number of genetic mitochondrial disorders whose manifestations range from muscle weakness to organ failure. In this context, improvements in mitochondrial function and cellular bioenergetics represent potential targets for therapeutic intervention in mitochondrial diseases.
These compounds are able to quench ROS and lipid peroxidation, maintain mitochondrial membrane potential and confer cytoprotection to cultured cells under conditions of induced oxidative stress. These properties are related to their ability to quench reactive oxygen radicals; therefore, the compounds have been denoted multifunctional radical quenchers (MRQs).
The ability of these compounds to quench lipid peroxidation induced by depletion of glutathione with diethyl maleate (DEM) was evaluated in Friedreich’s ataxia (FRDA) lymphocytes.
