Structural basis for specific ligation of the peroxisome proliferator-activated receptor δ.

ABSTRACT: The peroxisome proliferator-activated receptor (PPAR) family comprises three subtypes: PPARα, PPARγ, and PPARδ. PPARδ transcriptionally modulates lipid metabolism and the control of energy homeostasis; therefore, PPARδ agonists are promising agents for treating a variety of metabolic disorders. In the present study, we develop a panel of rationally designed PPARδ agonists. The modular motif affords efficient syntheses using building blocks optimized for interactions with subtype-specific residues in the PPARδ ligand-binding domain (LBD). A combination of atomic-resolution protein X-ray crystallographic structures, ligand-dependent LBD stabilization assays, and cell-based transactivation measurements delineate structure-activity relationships (SARs) for PPARδ-selective targeting and structu
