| Popis: | Novel bacterial topoisomerase inhibitors (NBTIs) are an important new class of antibacterials targeting bacterial type II topoisomerases (DNA gyrase and topoisomerase IV). Notwithstanding their potent antibacterial activity, they suffer from a detrimental class-related hERG blockage. In this study, we designed and synthesized an optimized library of NBTIs comprising different linker moieties that exhibit reduced hERG inhibition and retain inhibitory potencies on DNA gyrase and topoisomerase IV of Staphylococcus aureus and Escherichia coli, respectively, as well as potent antibacterial activities. Substitution of the linker’s tertiary amine with polar groups outcome in diminished hERG inhibition. Compound 17 expresses nanomolar enzyme inhibitory potency and antibacterial activity against both Gram-positive and Gram-negative bacteria as well as reduced hERG inhibition relative to our previously published NBTI analogs. Here, we point to some important NBTI’s structural features that influence their hERG inhibitory activity. Članek objavljen 11. 8. 2022. Članek št. 106087. Bibliografija: str. 13-14. Abstract.
