== Publication Abstract from PubMed == | |||
Peroxisome proliferator-activated receptors (PPARs) are nuclear receptor-type transcription factors that consist of three subtypes (alpha, gamma, and beta/delta) with distinct functions and PPAR dual/pan agonists are expected to be the next generation of drugs for metabolic diseases. Saroglitazar is the first clinically approved PPARalpha/gamma dual agonist for treatment of diabetic dyslipidemia and is currently in clinical trials to treat non-alcoholic fatty liver disease (NAFLD); however, the structural information of its interaction with PPARalpha/gamma remains unknown. We recently revealed the high-resolution co-crystal structure of saroglitazar and the PPARalpha-ligand binding domain (LBD) through X-ray crystallography, and in this study, we report the structure of saroglitazar and the PPARgamma-LBD. Saroglitazar was located at the center of "Y"-shaped PPARgamma-ligand-binding pocket (LBP), just as it was in the respective region of PPARalpha-LBP. Its carboxylic acid was attached to four amino acids (Ser289/His323/His449/Thr473), which contributes to the stabilization of Activating Function-2 helix 12, and its phenylpyrrole moiety was rotated 121.8 degrees in PPARgamma-LBD from that in PPARalpha-LBD to interact with Phe264. PPARdelta-LBD has the consensus four amino acids (Thr253/His287/His413/Tyr437) towards the carboxylic acids of its ligands, but it seems to lack sufficient space to accept saroglitazar because of the steric hindrance between the Trp228 or Arg248 residue of PPARdelta-LBD and its methylthiophenyl moiety. Accordingly, in a coactivator recruitment assay, saroglitazar activated PPARalpha-LBD and PPARgamma-LBD but not PPARdelta-LBD, whereas glycine substitution of either Trp228, Arg248, or both of PPARdelta-LBD conferred saroglitazar concentration-dependent activation. Our findings may be valuable in the molecular design of PPARalpha/gamma dual or PPARalpha/gamma/delta pan agonists. | |||
