A series of benzamide scaffolds were designed and synthesized by the thiazinone ring opening of PBTZ169, and N-benzyl 3,5-dinitrobenzamides were finally identified as anti-TB agents in this work. 3,5-Dinitrobenzamides D5, 6, 7, and 12 exhibit excellent in vitro activity against the drug susceptive Mycobacterium tuberculosis H37Rv strain (MIC: 0.0625 μg/mL) and two clinically isolated multidrug-resistant
通过PBTZ169的噻嗪酮开环设计并合成了一系列苯甲酰胺支架,最终鉴定出N-苄基3,5-二硝基苯甲酰胺是抗结核药物。3,5- Dinitrobenzamides D5,6,7,和12表现出优异的体外对抗药物易感活性的结核分枝杆菌H37Rv的菌株(MIC:0.0625微克/毫升)和两个临床分离多药耐药性菌株(MIC <0.016-0.125微克/毫升)。化合物D6与PBTZ169相比,显示出可接受的安全性和更好的药代动力学特征,表明其有望成为未来抗结核药物发现的先导化合物。
