Abstract

A series of PPARdelta-selective agonists was investigated and optimized for a favorable in vivo pharmacokinetic profile. Isoxazole LCI765 (17d) was found to be a potent and selective PPARdelta agonist with good in vivo PK properties in mouse (C(max)=5.1 microM, t(1/2)=3.1 h). LCI765 regulated expression of genes involved in energy homeostasis in relevant tissues when dosed orally in C57BL6 mice. A co-crystal structure of compound LCI765 and the LBD of PPARdelta is discussed.
