A method of identifying compounds as direct inhibitors of Keap1-Nrf2 interaction through high-throughput screening and lead development. The direct inhibitors of Keap1-Nrf2 interaction are more specific and free of various undesirable effects than existing indirect inhibitors, and are potential drug candidates of chemopreventive and therapeutic agents for treatment of various diseases or conditions involving oxidative stress and/or inflammation, including but not limited to cancers, diabetes, Alzheimer's, and Parkinson's. Novel compounds are identified and methods of preventing or treating diseases or conditions related to Keap1-Nrf2 interaction activity by use of the novel compounds identified or compositions containing such compounds are also disclosed.

perborate in acetic acid is an effective reagent for the oxidation of anilines to nitroarenes and of sulphides to either sulphoxides or sulphones. It is also an excellent reagent for the oxidative deprotection of ketone dimethylhydrazones. Baeyer-Villiger oxidation of ketones can be carried out with sodium perborate in either trifluoroacetic acid or acetic acid/trifluoroacetic acid mixtures, and hydroquinones

Methyltrioxorhenium-catalyzed oxidation of sulfides with hydrogenperoxide in ethanol has been found to be an efficient catalytic system for the selective formation of sulfoxides and sulfones. The oxidation using an equimolar amount of hydrogenperoxide afforded sulfoxides in excellent yield, and the use of two molar amounts of hydrogenperoxide gave sulfones quantitatively. Strongly deactivated sulfide, bis(4-nitrophenyl)
late-stage oxygenation of sulfur-containing complex molecules with ground-stateoxygen under ambient conditions. The high oxidation potential of the active uranyl cation (UO2 2+ ) enabled the efficient synthesis of sulfones. The ligand-to-metal charge transfer process (LMCT) from O 2p to U 5f within the O=U=O group, which generates a UV center and an oxygen radical, is assumed to be affected by the solvent
