A Novel Pre-fluorescent Nitroxide Probe for the Highly Sensitive Determination of Peroxyl and Other Radical Oxidants
ABSTRACT Peroxyl and other radical oxidants react with stable cyclic nitroxides, such as the piperidinyl and pyrrolidinyl nitroxides to form initially the one electron oxidation product, the oxoammonium cation. For most ...
Total Synthesis of (3R,3'R,6'R)-Lutein, (3R,3'R)-Zeaxanthin and Their Stereoisomers
(3R,3'R,6'R)-Lutein (1) and (3R,3'R)-zeaxanthin (5) are dietary carotenoids that are found in most fruits and vegetables. Numerous studies have shown that 1 and 5 play an important role in the prevention of age-related ...
