Upon administration, PLED-based MnSOD mimetic mimics MnSOD and scavenges oxygen free radicals such as superoxide anion, hydrogen peroxide, and hydroxyl radical, thereby preventing oxygen free radical damage to macromolecules such as DNA and minimizing oxygen free radical-related chemotoxicity in normal tissues.

In addition, orthoquinone intermediates, metabolized from combretastatin A1 by oxidative enzymes found to be elevated in some tumor types, may bind to tumor cell thiol-specific antioxidant proteins and DNA, and stimulate oxidative stress by enhancing superoxide/hydrogen peroxide production.
(Combretastatin A1 Diphosphate, NCI Thesaurus)
Manuka honey contains a significant higher concentration of the 1,2-dicarbonyl compound methylglyoxal, which may account for its antibacterial activity; this agent may release small amounts of hydrogen peroxide which may also contribute to its antibacterial activity.

Consisting of manganese (II) ions chelated to fodipir (dipyridoxyl diphosphate or DPDP), mangafodipir scavenges oxygen free radicals such as superoxide anion, hydrogen peroxide, and hydroxyl radical, potentially preventing oxygen free radical damage to macromolecules such as DNA and minimizing oxygen free radical-related chemotoxicity in normal tissues.
(Mangafodipir Trisodium, NCI Thesaurus)
Platinum decomposes hydrogen peroxide and powers propulsion of the donuts.
