Abstract

This Letter describes the discovery of a series of potent inhibitors of Human Uric Acid Transporter 1 (hURAT1). Lead generation and optimization via 3D pharmacophore analysis resulted in compound 41. With an IC50 of 33.7nM, 41 also demonstrated good oral bioavailability in rat (74.8%) and displayed a consistent PK profile across all species tested (rat, dog and monkey).
