To assess the oxidative activation mechanism and anticancer cytotoxicity of indole-3-acetic acid derivatives combined with horseradish peroxidase as an enzyme-prodrug therapy.
Characterized the one-electron oxidation and radical fragmentation kinetics of indole-3-acetic acid and ring-substituted analogs reacting with horseradish peroxidase in anoxic, hypoxic, and oxic environments.
Evaluated the in vitro cytotoxicity of horseradish peroxidase paired with indole-3-acetic acid prodrugs against mammalian and human tumor cell lines.
Horseradish peroxidase efficiently catalyzed the one-electron oxidation of indole-3-acetic acid without added hydrogen peroxide, releasing carbon dioxide and yielding reactive carbon-centered and peroxyl radicals.
The enzyme-prodrug combination exhibited potent cytotoxicity toward mammalian and human cancer cells, with specific halogen-substituted derivatives demonstrating high cytotoxic activity despite increased resistance to oxidation.
