Abstract: The gyraseB subunit of Staphylococcus aureus DNA gyrase is a well-established and validated target though less explored for the development of novel antimicrobial agents. Starting from the available structural information in PDB (3TTZ), we identified a novel series of benzimidazole used as inhibitors of DNA gyraseB with low micromolar inhibitory activity by employing structure-based drug design strategy. Subsequently, this chemical class of DNA gyrase inhibitors was extensively investigated biologically through in vitro assays, biofilm inhibition assays, cytotoxicity, and in vivo studies. The binding affinity of the most potent inhibitor 10 was further ascertained biophysically through differential scanning fluorimetry. Further, the most potent analogues did not show any signs of cardiotoxicity in Zebra fish ether-a-go-go-related gene (zERG), a major breakthrough among the previously reported cardiotoxic gyraseB inhibitors.
