Abstract
A series of α-ethylphenylpropanoic acid derivatives was prepared as candidate peroxisome proliferator-activated receptor (PPAR) α-selective agonists, based on our PPARα/δ 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 PPARα agonistic activity and PPARα selectivity, as had been predicted from a molecular-modeling study. A representative compound blocked the progression of nonalcoholic steatohepatitis (NASH) in an animal model.
