3-(4-Alkoxyphenyl)propanoic acid derivatives were prepared as candidate peroxisome proliferator-activated receptor (PPAR) alpha/delta/gamma pan agonists, based on our previous SAR studies directed toward the development of subtype-selective PPAR agonists. Those studies indicated that the steric bulkiness of substituents introduced at the distal benzene ring had an important influence on PPAR activity. The finding that a 4-adamantyl derivative exhibited not only PPAR alpha/delta activity but also significant PPAR gamma activity prompted us to search for structurally novel phenylpropanoic acid derivatives with more potent adipocyte differentiation activity than the well-known PPAR-gamma agonist, rosiglitazone, as well as well-balanced PPAR alpha and PPAR delta agonistic activities. A representative phenylpropanoic acid derivative (12) bearing a 4-adamantylphenyl substituent proved to be a well-balanced PPAR-pan agonist with activities to regulate the expression of genes involved in lipid and glucose homeostasis, and should be useful as a candidate drug for the treatment of altered PPAR function.
