Therapeutic implications of targeting antioxidants to mitochondria

Abstract Redox and oxidative balance are mainly regulated by mitochondria, which control the life and death of cells and organisms, and are therefore implicated in multiple pathologies. Mitochondria can be considered key organelles to be used in different therapeutically approaches, and mitochondria-targeted antioxidants have already shown great potential in the treatment of various human diseases. In fact, major progress has been achieved in the development of different molecules targeted to mitochondria. In this chapter, we will discuss the various strategies that have been employed, such as molecules conjugated with lipophilic cations (e.g., triphenylphosphonium) and peptide-based compou…
