3-(2-Aminocarbonylphenyl)propanoic acid analogs as potent and selective EP3 receptor antagonists. Part 3: Synthesis, metabolic stability, and biological evaluation of optically active analogs
ic 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
