Abstract

The synthesis of a series of tricyclic antagonists for the prostaglandin D(2) receptor DP2 (CRTH2) is disclosed. The activities of the compounds were evaluated in a human DP2 binding assay and a human whole blood eosinophil shape change assay. Potential metabolic liabilities of the compounds were addressed through in vitro CYP studies. The lead compound was demonstrated to have efficacy in a mouse model of allergic rhinitis following oral dosing.
