Abstract:
The fluorescence of 9,10-dioxa-syn-3,4,6,7-tetramethylbimane (bimane) was found to be quenched in the presence of guanosine 5'-monophosphate. By using this phenomenon, the bimane system was used for the fluorophor of substrates for phosphodiesterase I. Bimanes were coupled to 5'-guanylic acid and the resulting compounds were shown to be portent fluorogenic substrates for the assay of phosphodiesterase I.
