Title: Discovery of AAT-008, a novel, potent, and selective prostaglandin EP4 receptor antagonist.
Authors: Okumura Y, Yamagishi T, Nukui S, Nakao K.
Abstract: Starting from acylsufonamide HTS hit 2, a novel series of para-N-acylaminomethylbenzoic acids was identified and developed as selective prostaglandin EP4 receptor antagonists. 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 pharmacological profiles over grapiprant (1).
