In this study, a novel reporter substrate named C8CF3-coumarin was synthesized and then characterized, an assay protocol was developed to identify small molecular activators of PLCγ enzymes, and a proof-of-principle high throughput screen was conducted using PLCγ2 and the LOPAC1280 library. These studies showed that C8CF3-coumarin could indeed monitor PLCγ enzyme activity and identify potential small molecule activators from a screen. The identification of such small molecule PLCγ2 activators would be of great utility to the Alzheimer's disease research community by serving as both chemical probes to study the modulation of PLCγ2 and as potential therapeutic agents.
