Tuberculosis remains a leading cause of death resulting from an infectious agent, and the spread of multi- and extensively drug-resistant strains of Mycobacterium tuberculosis poses a threat to management of global health. New drugs that effectively shorten the duration of treatment and are active against drug-resistant strains of this pathogen are urgently required to develop effective chemotherapies to combat this disease. Two nitroimidazoles, PA-824 and OPC-67683, are currently in Phase II clinical trials for the treatment of TB and the outcome of these may determine the future directions of drug development for anti-tubercular nitroimidazoles. In this review we summarize the development of these nitroimidazoles and alternative analogs in these series that may offer attractive alternatives to PA-824 and OPC-67683 for further development in the drug-discovery pipeline. Lastly, the potential pitfalls in the development of nitroimidazoles as drugs for TB are discussed.
结核病仍然是由感染因子导致的主要死亡原因,而耐多药和广泛耐药结核分枝杆菌菌株的传播对全球卫生管理构成了威胁。迫切需要新的药物来有效缩短治疗时间,并对这种病原体的耐药菌株具有活性,以开发有效的化疗方法来对抗这种疾病。两种硝基咪唑类药物 PA-824 和 OPC-67683 目前正在进行治疗结核病的 II 期临床试验,这些试验的结果可能决定抗结核硝基咪唑类药物的未来药物研发方向。在这篇综述中,我们总结了这些硝基咪唑类药物以及该系列中其他类似物的开发情况,这些类似物可能为 PA-824 和 OPC-67683 提供有吸引力的替代品,以进一步开发药物发现管道。最后,讨论了将硝基咪唑类药物开发为结核病药物的潜在陷阱。
