We designed and synthesized novel PPAR delta antagonists based on the crystal structure of the PPAR delta full agonist TIPP-204 bound to the PPAR delta ligand-binding domain, in combination with our nuclear receptor helix 12 folding modification hypothesis. Representative compound 3a exhibits PPAR delta-preferential antagonistic activity. (C) 2009 Elsevier Ltd. All rights reserved.
Improvement of water-solubility of biarylcarboxylic acid peroxisome proliferator-activated receptor (PPAR) δ-selective partial agonists by disruption of molecular planarity/symmetry
disruption of molecular planarity and symmetry. All 2-substitutedbiphenyl analogs examined showed more potent PPARδ agonistic activity with greater aqueous solubility than 1 or 2. Among these biphenyls, 25 showed potent and selective PPARδ partial agonistic activity (EC50: 5.7 nM), with adequate solubility in phosphate buffer (0.022 mg/mL). The 2-substituted pyridyl analog 27 showed weaker PPARδ partial
