Abstract

Multiple screening approaches were carried out to identify novel chemistry starting for Pyruvate Dehydrogenase Kinases (PDHKs) inhibitors. Through hit triaging efforts and structure-based optimization, two series of ATP competitive inhibitors with single digit nanomolar enzymatic potency for PDHK1/2 and around 10-100-fold selectivity over PDHK4/3 were discovered. Approach of covalent inhibitor was explored to successfully improve the cellular target engagement to single digit micromolar range.
