Herein we describe the structure-aided design and synthesis of a series of pyridone-conjugated monohactam analogues with in vitro, antibacterial activity against clinically relevant Grain-negative species including Pseuedomonas aeruginosa, Klebsiella pneumoniae, and Escherichia coli. Rat pharmacokinetic studies with,compound 17 demonstrate low clearance and low plasma protein binding. In addition evidence is provided for a number of analogues suggesting that the siderophore receptors PiuA and PirA play a role in drug uptake in P. aeruginosa strain PAO1.
