  摘要：

  New heterocyclic analogues of the potent biphenyl class derived from antitubercular drug PA-824 were prepared, aiming to improve aqueous solubility but maintain high metabolic stability and efficacy. The strategy involved replacement of one or both phenyl groups by pyridine, pyridazine, pyrazine, or pyrimidine, in order to reduce lipophilicity. For para-linked biaryls, hydrophilicities (ClogP) correlated with measured solubilities, but highly soluble bipyridine analogues displayed weak antitubercular activities. A terminal pyridine or proximal heterocycle allowed retention of potency and provided solubility improvements, particularly at low pH, with examples from the latter classes displaying the better in vivo efficacies, high metabolic stabilities, and excellent pharmacokinetics. Five such compounds were >100-fold better than the parent drug in a mouse model of acute Mycobacterium tuberculosis infection, and two orally bioavailable pyridine analogues (3-4-fold more soluble than the parent at low pH) were superior to antitubercular drug OPC-67683 in a chronic infection model.

  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。
