An electrophilic fragment library of small heterocycles was developed and characterized in the surrogate GSH-reactivity assay and aqueous stability test that revealed their potential as covalent warheads. Screening the library against MurA from Staphylococcus aureus (MurA SA ) and Escherichia coli (MurA EC ) identified heterocyclic fragments with significant inhibitory potency. The validated heterocyclic warhead library might be useful for developing targeted covalent inhibitors for other targets of interest with a new design strategy incorporating heterocyclic electrophiles as warheads.
