Peroxisome proliferator-activated receptor ? (PPAR?) is a well-known target for thiazolidinedione antidiabetic drugs. In this paper, we present the synthesis and biological evaluation of a series of dihydropyrano[2,3-c]pyrazole derivatives as a novel family of PPAR? partial agonists. Two analogues were found to display high affinity for PPAR? with potencies in the micro molar range. Both of these hits were selective against PPAR?, since no activity was measured when tested against PPARα, PPAR? and RXRα. In addition, a novel modelling approach based on multiple individual flexible alignments was developed for the identification of ligand binding interactions in PPAR?. In combination with cell-based transactivation experiments, the flexible alignment model provides an excellent analytical tool to evaluate and visualize the effect of ligand chemical structure with respect to receptor binding mode and biological activity.
