  Design, Synthesis, and Characterization of Novel Tetrahydropyran-Based Bacterial Topoisomerase Inhibitors with Potent Anti-Gram-Positive Activity

  摘要：

  There is an urgent need for new antibacterial drugs that are effective against infections caused by multidrug-resistant pathogens. Novel nonfluoroquinolone inhibitors of bacterial type II topoisomerases (DNA gyrase and topoisomerase IV) have the potential to become such drugs because they display potent antibacterial activity and exhibit no target-mediated cross-resistance with fluoroquinolones. Bacterial topoisomerase inhibitors that are built on a tetrahydropyran ring linked to a bicyclic aromatic moiety through a syn-diol linker show potent anti-Gram-positive activity, covering isolates with clinically relevant resistance phenotypes. For instance, analog 49c was found to be a dual DNA gyrase topoisomerase IV inhibitor, with broad antibacterial activity and low propensity for spontaneous resistance development, but suffered from high hERG K channel block. On the other hand, analog 49e displayed lower hERG K channel block while retaining potent in vitro antibacterial activity and acceptable frequency for resistance development. Furthermore, analog 49e showed moderate clearance in rat and promising in vivo efficacy against Staphylococcus aureus in a murine infection model.

  There is an urgent unmet medical need for novel antibiotics that are effective against a broad range of bacterial species, especially multidrug resistant ones. Tetrahydropyran-based inhibitors of bacterial type II topoisomerases (DNA gyrase and topoisomerase IV) display potent activity against Gram-positive pathogens and no target-mediated cross-resistance with fluoroquinolones.

  对新型抗生素有效且广泛的细菌种类，特别是对多药耐药的细菌种类，有效地满足了迫切的医学需求。细菌II型拓扑异构酶（DNA促旋酶和拓扑异构酶IV）的基于四氢吡喃的抑制剂表现出对革兰氏阳性病原体的有效活性，并且与氟喹诺酮类药物无靶标介导的交叉耐药性。我们报告了我们的研究成果，旨在将这类分子的抗菌谱扩展为难以治疗的革兰氏阴性病原体。理化性质（极性和碱性）被认为可以指导设计过程。二元四氢吡喃基化合物，例如6和21是DNA促旋酶和拓扑异构酶IV的有效抑制剂，对革兰氏阳性和革兰氏阴性病原体（金黄色葡萄球菌，肠杆菌科，铜绿假单胞菌和鲍曼不动杆菌）表现出抗菌活性。化合物6和21在临床相关的鼠类感染模型中是有效的。
