SAR-oriented discovery of peroxisome proliferator-activated receptor pan agonist with a 4-adamantylphenyl group as a hydrophobic tail
摘要:
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.

Structure-based design, synthesis, and nonalcoholic steatohepatitis (NASH)-preventive effect of phenylpropanoic acid peroxisome proliferator-activated receptor (PPAR) α-selective agonists
摘要:
A series of alpha-ethylphenylpropanoic acid derivatives was prepared as candidate peroxisome proliferator-activated receptor (PPAR) alpha-selective agonists, based on our PPAR alpha/delta dual agonist 3 as a lead compound. Structure-activity relationship studies clearly indicated that the steric bulkiness and position of the distal hydrophobic tail part are critical for PPAR alpha agonistic activity and PPAR alpha selectivity, as had been predicted from a molecular-modeling study. A representative compound blocked the progression of nonalcoholic steatohepatitis (NASH) in an animal model. (C) 2011 Elsevier Ltd. All rights reserved.
