Abstract: High-throughput screening facilitates the rapid identification of novel hit compounds;
however, it remains challenging to design effective high-throughput assays, partially
due to the difficulty of achieving sensitivity in the assay techniques. Among the
various analytical methods that are used, fluorescence-based assays dominate due to their
high sensitivity and ease of operation. Recent advances in activity-based sensing/imaging
have further expanded the availability of fluorescent probes as monitors for high-throughput
screening of result outputs. In this study, we have reviewed various activity-based fluorescent
probes used in high-throughput screening assays, with an emphasis on their
structure-related working mechanisms. Moreover, we have explored the possibility of developing
additional and better probes to boost hit identification and drug development
against various targets.
