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. We report our research
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。
