PubMed Abstract:
N -Myristoyltransferase (NMT) represents an attractive drug target in parasitic infections such as malaria due to its genetic essentiality and amenability to inhibition by drug-like small molecules. Scaffold simplification from previously reported inhibitors containing bicyclic cores identified phenyl derivative 3 , providing a versatile platform to study the effects of substitution on the scaffold, which yielded pyridyl 19 . This molecule exhibited improved enzyme and cellular potency, and reduced lipophilicity compared to inhibitor 3 . Further structure-based inhibitor design led to the discovery of 30 , the most potent inhibitor in this series, which showed single-digit nM enzyme affinity and sub-μM anti-plasmodial activity.
