Reaktionsschritte

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 coeluting 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.
