Abstract

Antibiotics with novel mechanisms of action are desperately needed to combat the increasing rates of multidrug-resistant infections. Bacterial pantothenate kinase (PanK) has emerged as a target of interest to cut off the biosynthesis of coenzyme A. Herein we report the results of an in vitro high-throughput screen of over 10 000 small molecules against Bacillus anthracis PanK, as well as a follow-up screen of hits against PanK isolated from Pseudomonas aeruginosa and Burkholderia cenocepacia. Nine hits are structurally categorized and analyzed to set the stage for future drug development.

Keywords: Bacillus; Pseudomonas; antibiotic resistance; high-throughput screening; pantothenate kinase.
