A series of 1,4-benzyloxybenzylsulfanylaryl carboxylic acids were prepared and their activities for PPAR receptor subtypes (alpha, beta, and gamma) with potential indications for the treatment of dyslipidemia were investigated. Analog 13a displayed the greatest binding affinity (IC50 = 10 nM) and selectivity (120-fold) for PPAR delta over PPAR alpha. Many of the analogs investigated were found to be highly selective for PPAR delta and were dependent on the point of attachment of the substituent. In the 1,4-series, analog 28e was found to be the most potent (IC50 = 1.7 nM) and selective (> 1000-fold) compound for PPAR delta. None of the compounds tested showed appreciable binding affinity for PPAR gamma. (c) 2007 Elsevier Ltd. All rights reserved.
