Tuberculosis, caused by Mycobacterium tuberculosis (Mtb), is the infectious disease responsible for the highest number of deaths worldwide. Herein, 22 new N-oxide-containing compounds were synthesized followed by in vitro and in vivo evaluation of their antitubercular potential against Mtb. Compound 8 was found to be the most promising compound, with MIC90 values of 1.10 and 6.62 μM against active
由结核分枝杆菌(Mtb)引起的结核病是导致全世界死亡人数最多的传染病。本文中,合成了22种新的含N-氧化物的化合物,然后在体外和体内评估了它们对Mtb的抗结核潜力。发现化合物8是最有前途的化合物,相对于活性Mtb和非复制Mtb的MIC 90值分别为1.10和6.62μM 。此外,我们进行了体内实验以确认化合物8的安全性和有效性; 该化合物被发现具有口服生物利用度并且非常有效,从而导致Mtb降低至小鼠感染模型中无法检测到的水平。基于微阵列的作用机理初步研究表明化合物8阻止翻译。总而言之,这些结果表明苯并呋喃聚糖衍生物8是用于开发新型化学类抗结核药物的有前途的先导化合物。
