In particular, a cycloalkyl acid derivative represented by general formula (I) and a medical salt thereof, a preparation method thereof, and an application of the cycloalkyl acid derivative and the medical salt thereof as URAT1 inhibitors, and particularly as therapeutic agents for diseases related to an abnormal uric acid level are described, wherein definitions of substituent groups in general formula (I) are the same as the definitions in the specification.
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 33.7 nM, 41 also demonstrated good oral bioavailability in rat (74.8%) and displayed a consistent PK profile across all species tested (rat, dog and monkey).
