This invention provides a compound of the formula (I): wherein A represents a phenyl group or the like: B represents an aryl or the like: E represents a 1,4-phenylene group; R1 and R2 independently represent a hydrogen atom or the like: R3 and R4 independently represent a hydrogen atom or the like: R5 represents -CO2H or the like:R6 represents an alkyl group having from 1 to 6 carbon atoms or the like: X represents a methylene group or the like. These compounds are useful for the treatment of disease conditions mediated by prostaglandin such as pain, or the like in mammalian. The compounds act as antagonists of the prostaglandin E2 receptor. This invention also provides a pharmaceutical composition comprising the above compound.

ylbenzoic acids was identified and developed as selective prostaglandin EP4 receptorantagonists. Structural modifications on lead compound 4a were explored with the aim of improving potency, physicochemical properties, and animal PK predictive of QD (once a day) dosing regimen in human. These efforts led to the discovery of the clinical candidate AAT-008 (4j), which exhibited significantly improved
