Abstact

Bacterial DNA gyrase is an attractive target for the investigation of new antibacterial agents. Inhibitors of the GyrB subunit, which contains the ATP-binding site, are described in this communication. Novel, substituted 5-(1H-pyrazol-3-yl)thiazole compounds were identified as inhibitors of bacterial gyrase. Structure-guided optimization led to greater enzymatic potency and moderate antibacterial potency. Data are presented for the demonstration of selective enzyme inhibition of Escherichia coli GyrB over Staphylococcus aureus GyrB.
