Abstract:

Systematic structure-activity relationship(SAR) exploration of a moderately active tetrazole-bearing lesinurad-based hit 1f led to the discovery of a potent uric acid transporter 1(URAT1) inhibitor 1i, which possessed a novel molecular skeleton and was 11-fold more potent than the parent lesinurad against human URAT1 in-vitro (IC50=0.66 μmol/L for 1i vs. 7.18 μmol/L for lesinurad).

Key words: URAT1 inhibitor, Structure-activity relationship, Drug discovery, Lesinurad, Tetrazole, Bioisostere
