T. Kajiki et al., RATE ACCELERATION OF THE OXIDATION OF AN NADH MODEL BY FLAVIN WITH A FUNCTIONALIZED FLAVIN RECEPTOR IN CHLOROFORM, Chemistry Letters, (11), 1995, pp. 1063-1064
A melamine derivative bearing a guanidinium ion was found to enhance t
he oxidation-activity of flavin via hydrogen bonding at the N(1) posit
ion of the isoalloxazine ring for the oxidation of N-benzyl-1,4-dihydr
onicotinamide (BNAH) in CHCl3.
