Putative binding interactions of compound 2 against bacterial topoisomerase II DNA gyrase. The ASP437 residue (shown in red) located at the active site of topoisomerase II DNA gyrase forms H-bond (dotted line in green) with OH group of compound 2, in a similar way to hydrogen bond formation between the GSK299423 inhibitor and the enzyme [32].
