  Synthesis and Structure−Activity Studies of Biphenyl Analogues of the Tuberculosis Drug (6S)-2-Nitro-6-{[4-(trifluoromethoxy)benzyl]oxy}-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazine (PA-824)

  摘要：

  A series of biphenyl analogues of the new tuberculosis drug PA-824 was prepared, primarily by coupling the known (6S)-2-nitro-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazin-6-ol with iodobenzyl halides, followed by Suzuki Coupling Of these iodides with appropriate arylboronic acids or by assembly of the complete biaryl side chain prior to coupling with the above alcohol. Antitubercular activity was determined under both replicating (MABA) and nonreplicating (LORA) conditions. para-Linked biaryls were the most active, followed by meta-linked and then ortho-linked analogues. A more detailed study of a larger group of para-linked analogues showed a significant correlation between potency (MABA) and both lipophilicity (CLOGP) and the electron-withdrawing properties of terminal ring substituents (Sigma sigma). Selected compounds Were evaluated for their efficacy in a mouse model of acute Mycobacterium tuberculosis infection. In vivo activity correlated well with the stability of compounds to microsomal metabolism. Three compounds bearing combinations of lipophilic, electron-withdrawing groups achieved >200-fold higher efficacies than the parent drug.

  The current invention provides a series of bicyclic nitroimidazole-substituted phenyl oxazolidinones in which a bicyclic nitroimidazole pharmacophore is covalently bonded to a phenyl oxazolidinone, their pharmaceutical compositions, and the method of use of the compositions for prevention and treatment of bacterial infections. The bicyclic nitroimidazole-substituted phenyl oxazolidinones possess surprising antibacterial activity against wild-type and resistant strains of pathogens, and are therefore useful for the prevention, control and treatment of a number of human and veterinary bacterial infections caused by these pathogens, such as Mycobacterium tuberculosis.

  本发明提供了一系列双环硝基咪唑取代的苯基噁唑烷酮，其中双环硝基咪唑药效团与苯基噁唑烷酮共价键合，它们的制药组合物以及用于预防和治疗细菌感染的组合物的使用方法。这些双环硝基咪唑取代的苯基噁唑烷酮对野生型和耐药菌株具有惊人的抗菌活性，因此对于预防、控制和治疗由这些病原体引起的许多人类和兽医细菌感染是有用的，如结核分枝杆菌。
