Reaction Steps

In order to confirm the pentose-derived nature of the native fluorophore 100 mM each of L-lysine, L-arginine and D-ribose were heated for 1 hour at 80° C. Injection of a small amount of this synthetic material on HPLC revealed a major fluorescent peak co-eluting with the native fluorophore. (see FIG. 5) In order to substantiate the proposed structure, the synthetic fluorophore was prepared preparatively and purified. Total yield was 21 mg; i.e., 0.02% of the reactants.
