Syntheses and Reactivity of Bisflavins. Oxidation of N-Benzyl-1,4-dihydronicotinamide by Flavins in Aqueous Solution

Article abstract of DOI:10.1039/P29840001227

Several bisflavins linked at the 10,10'-positions of isoalloxazine rings have been synthesized.The kinetics of the oxidation of N-benzyl-1,4-dihydronicotinamide in aqueous solution have been examined.It has been found that each flavin of a bisflavin is considerably influenced by another intramolecular flavin moiety due to the formation of a charge-transfer complex between intramolecularly reduced and oxidized flavins.The formation of the complex depends on the conformation.
