  具有改善的hERG和抗结核分枝杆菌的体内功效的新型基于N-联氨基氨基哌啶的促旋酶抑制剂

  摘要：

  DNA促旋酶是开发抗结核分枝杆菌药物的临床验证靶标（MTB）。尽管有希望将氟喹诺酮类药物（FQs）用作抗结核药物，但先前对FQs耐药的流行很可能会限制其临床价值。我们描述了一种新型的N-连接的氨基哌啶基烷基喹诺酮类和萘啶酮类，通过抑制DNA促旋酶活性杀死Mtb。DNA促旋酶的抑制机制与氟喹诺酮类截然不同，其抑制氟喹诺酮类抗性Mtb生长的能力证明了这一点。生化研究表明，该类化合物通过单链裂解而不是双链裂解发挥作用，如氟喹诺酮类药物所见。这些化合物对细胞外和细胞内的Mtb具有高度的杀菌作用。铅的优化导致鉴定了具有改善的口服生物利用度并降低了心脏离子通道负担的有效化合物。该系列化合物在各种结核病鼠模型中均有效。

  Benzimidazoles: Novel Mycobacterial Gyrase Inhibitors from Scaffold Morphing

  摘要：

  Type II topoisomerases are well conserved across the bacterial species, and inhibition of DNA gyrase by fluoroquinolones has provided an attractive option for treatment of tuberculosis (TB). However, the emergence of fluoroquinolone-resistant strains of Mycobacterium tuberculosis (Mtb) poses a threat for its sustainability. A scaffold hopping approach using the binding mode of novel bacterial topoisomerase inhibitors (NBTIs) led to the identification of a novel class of benzimidazoles as DNA gyrase inhibitors with potent anti-TB activity. Docking of benzimidazoles to a NBTI bound crystal structure suggested that this class of compound makes key contacts in the enzyme active site similar to the reported NBTIs. This observation was further confirmed through the measurement of DNA gyrase inhibition, and activity against Mtb strains harboring mutations that confer resistance to aminopiperidines based NBTIs and Mtb strains resistant to moxifloxacin. Structure activity relationship modification at the C-7 position of the left-hand side ring provided further avenue to improve hERG selectivity for this chemical series that has been the major challenges for NBTIs.

  value. We describe a novel class of N-linked aminopiperidinyl alkyl quinolones and naphthyridones that kills Mtb by inhibiting the DNA gyrase activity. The mechanism of inhibition of DNA gyrase was distinct from the fluoroquinolones, as shown by their ability to inhibit the growth of fluoroquinolone-resistant Mtb. Biochemical studies demonstrated this class to exert its action via single-strand cleavage
