  Synthesis and Structure–Activity Relationships of Varied Ether Linker Analogues of the Antitubercular Drug (6S)-2-Nitro-6-{[4-(trifluoromethoxy)benzyl]oxy}-6,7-dihydro-5H-imidazo[2,1-b][1,3]oxazine (PA-824)

  摘要：

  New analogues of antitubercular drug PA-824 were synthesized, featuring alternative side chain ether linkers of varying size and flexibility, seeking drug candidates with enhanced metabolic stability and high efficacy. Both alpha-methyl substitution and removal of the benzylic methylene were broadly tolerated in vitro, with a biaryl example of the latter class exhibiting an 8-fold better efficacy than the parent drug in a mouse model of acute Mycobacterium tuberculosis infection and negligible fragmentation to an alcohol metabolite in liver microsomes. Extended linkers (notably propenyloxy, propynyloxy, and pentynyloxy) provided greater potencies against replicating M. tb (monoaryl analogues), with propynyl ethers being most effective under anaerobic (nonreplicating) conditions (mono/biaryl analogues). For benzyloxybenzyl and biaryl derivatives, aerobic activity was maximal with the original (OCH2) linker. One propynyloxy-linked compound displayed an 89-fold higher efficacy than the parent drug in the acute model, and it was slightly superior to antitubercular drug OPC-67683 in a chronic infection model.

  The introductions of the bicyclic 4-nitroimidazole and the oxazolidinone classes of antimicrobial agents represented the most significant advancements in the infectious disease area during the past two decades. Pretomanid, a bicyclic 4-nitroimidazole, and linezolid, an oxazolidinone, are also part of a combination regimen approved recently by the US Food and Drug Administration for the treatment of pulmonary, extensively drug resistant (XDR), treatment-intolerant or nonresponsive multidrug-resistant (MDR) Mycobacterium tuberculosis (TB). To identify new antimicrobial agents with reduced propensity for the development of resistance, a series of dual-acting nitroimidazole-oxazolidinone conjugates were designed, synthesized and evaluated for their antimicrobial activity. Compounds in this conjugate series have shown synergistic activity against a panel of anaerobic bacteria, including those responsible for serious bacterial infections.

  自行车环4-硝基咪唑和噁唑烷酮类抗微生物药物的介绍代表了过去二十年在传染病领域取得的最重要进展。Pretomanid是一种自行车环4-硝基咪唑，而利奈唑是一种噁唑烷酮，它们也是最近被美国食品药品监督管理局批准用于治疗肺部、广泛耐药（XDR）、治疗不耐受或对多药耐药（MDR）结核分枝杆菌（TB）的联合疗法的一部分。为了寻找具有减少耐药发展倾向的新抗微生物药物，设计、合成和评估了一系列双作用硝基咪唑-噁唑烷酮共轭物，以评估它们的抗微生物活性。这种共轭系列中的化合物已显示出对一系列厌氧细菌具有协同作用，包括那些导致严重细菌感染的细菌。

  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.
