  There is an emerging global need for new and more effective antibiotics against multi-resistant bacteria. This situation has led to massive industrial investigations on novel bacterial topoisomerase inhibitors (NBTIs) that target the vital bacterial enzymes DNA gyrase and topoisomerase IV. However, several of the NBTI compound classes have been associated with inhibition of the hERG potassium channel

  全球迫切需要新的更有效的抗生素来对抗多重耐药菌。这种情况导致了针对重要细菌酶 DNA 促旋酶和拓扑异构酶 IV 的新型细菌拓扑异构酶抑制剂 (NBTI) 的大规模工业研究。然而，一些 NBTI 化合物类别与抑制 hERG 钾通道有关，hERG 钾通道是心律失常的不良原因，通过漫长的合成路线挑战药物化学工作。我们在此提出了一种固相策略，可快速促进一类有前途的新型 NBTI 的化学合成。合成了一个概念验证文库，该文库能够通过支架替代调节 hERG 亲和力和抗菌活性。
