Structure-Based Design of Potent and Selective Inhibitors of the Metabolic Kinase PFKFB3

J Med Chem. 2015 Apr 23;58(8):3611-25. doi: 10.1021/acs.jmedchem.5b00352. Epub 2015 Apr 13.

Abstract

A weak screening hit with suboptimal physicochemical properties was optimized against PFKFB3 kinase using critical structure-guided insights. The resulting compounds demonstrated high selectivity over related PFKFB isoforms and modulation of the target in a cellular context. A selected example demonstrated exposure in animals following oral dosing. Examples from this series may serve as useful probes to understand the emerging biology of this metabolic target.
