The first fluorescent sensing system for dihydrouricline detection is presented. Dihydrouridine is the single most frequently occurring post-transcriptional modification in tRNA from bacteria and eukaryotes. A series of 10 boronic acid derivatives was prepared and their fluorogenic behaviours towards dihydrouridine and uridine were investigated. Whereas uridine always quenches fluorescence via pi-pi stacking interactions, several boronic acid sensors have been found to show substantial fluorescence enhancement upon binding with dihydrouridine.
