The present invention provides a fluorescent HPLC assay for detecting the presence and/or measuring the level of 20-hydroxyeicosatetraenoic acid (20-HETE) and other P-450 metabolites of arachidonic acid in a sample.

In one aspect, the invention relates to compounds useful as fluorescence assay probes, methods of making same, and methods of using same to assay ligand binding interactions with PXR.
