for the development of new antibacterial agents that are not impacted by target-mediated cross-resistance with fluoroquinolones. N-Linked amino piperidines, such as 7a, generally show potent antibacterial activity, including against quinolone-resistant isolates, but suffer from hERG inhibition (IC50 = 44 μM for 7a) and QT prolongation in vivo. We now disclose the finding that new analogues of 7a with
