PubMed Abstract: Peroxisome proliferator-activated receptor γ (PPARγ) is a molecular target of metabolic syndrome and inflammatory disease. PPARγ is an important nuclear receptor and numerous PPARγ ligands were developed to date; thus, efficient assay methods are important. Here, we investigated the incorporation of 7-diethylamino coumarin into the PPARγ agonist rosiglitazone and used the compound in a binding assay for PPARγ. PPARγ-ligand-incorporated 7-methoxycoumarin, , showed weak fluorescence intensity in a previous report. We synthesized PPARγ-ligand-incorporating coumarin, , in this report, and it enhanced the fluorescence intensity. The PPARγ ligand maintained the rosiglitazone activity. The obtained partial agonist appeared to act through a novel mechanism. The fluorescence intensity of and increased by binding to the ligand binding domain (LBD) of PPARγ and the affinity of reported PPARγ ligands were evaluated using the probe.
