Abstract

Novel bacterial type II topoisomerase inhibitors (NBTIs) constitute a promising new class of antibacterial agents. We report a series of NBTIs with potent anti-staphylococcal activity and diminished hERG inhibition. Dioxane-linked compound 9 demonstrated MICs ≤1 μg/mL against both methicillin-susceptible (MSSA) and -resistant Staphylococcus aureus (MRSA), accompanied by reduced hERG inhibition as compared to cyclohexane- or piperidine-linked analogs.
