Discovery and optimization of a biphenylacetic acid series of prostaglandin D2 receptor DP2 antagonists with efficacy in a murine model of allergic rhinitis
Biphenylacetic acid (5) was identified through a library screen as an inhibitor of the prostaglandin D2 receptor DP2 (CRTH2). Optimization for potency and pharmacokinetic properties led to a series of selective CRTH2 antagonists. Compounds demonstrated potency in a human DP2 binding assay and a human whole blood eosinophil shape change assay, as well as good oral bioavailability in rat and dog, and efficacy in a mouse model of allergic rhinitis following oral dosing.
