Amide linked redox-active naphthoquinones for the treatment of mitochondrial dysfunction.

ABSTRACT: Naphthoquinones have been investigated as potential therapeutic molecules for neurodegenerative disorders, which is largely based on their anti-oxidative potential. However, a theoretical framework for the pleiotropic protective effects of naphthoquinone derivatives is largely missing. We synthesized a library of novel short chain 2,3-disubstituted naphthoquinone derivatives and measured their redox characteristics to identify a potential connection with their biological activity. Using two cell lines with different reducing potential, the compounds were tested for their inherent toxicity, acute rescue of ATP levels and cytoprotective activity. For the first time, a structure-activity-relationship for naphthoquinones has been established. Our results clearly demonstrate that it is the grou
