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
