Abstract

A series of 3-(2-aminocarbonylphenyl)propanoic acid analogs possessing the (1R)-1-(3,5-dimethylphenyl)-3-methylbutylamine moiety on the carboxyamide side chain were synthesized and evaluated for their binding affinity for the EP1-4 receptors and their antagonist activity for the EP3 receptor. Rational drug design based on the structure of the metabolites in human liver microsomes led us to the discovery of another series of analogs. Several compounds were further evaluated for their in vivo efficacy in rats after oral administration and also for their pharmacokinetic profiles including in vitro stability in the liver microsomes.
