Synthesis and photochemical properties of caged peroxides for photocontrol of cellular oxidative stress

摘要

We developed a caged hydroperoxide, BhcTBHP, releasing prooxidant TBHP under blue light irradiation. MitoTBHP with triphenylphosphonium at position 7 triggered selective oxidative stress and membrane depolarization in mitochondria upon photoirradiation. This study presents a powerful tool for studying redox signaling and oxidative stress in living cells.
