A series of novel nitrofuranyl methyl N-heterocycles based on the structure of IIIM-MCD-211 were designed and synthesized. Compounds 6d, 8b and 12a show excellent activity against MTB H37Rv strain (MIC: 0.031–0.062 μg/mL) roughly comparable to INH and IIIM-MCD-211. In addition, a three-dimensional quantitative structure-activity relationship (3D-QSAR) study was performed on the above mentioned chemical series employing comparative molecular field analysis (CoMFA) and comparative molecular similarity index analysis (CoMSIA) techniques. The developed CoMFA and CoMSIA models display high external predictability (r²_pred of 0.954 and 0.935, respectively) and good statistical robustness. More importantly, the newly designed compounds 16a and 16b (MIC: <0.016 μg/mL) based on the two models, as expected, were found to be more active than 12a and IIIM-MCD-21. Design and synthesis of more potent nitrofuranyl methyl N-heterocycles as anti-TB agents are currently in progress.

设计并合成了一系列基于IIIM-MCD-211结构的新型硝基呋喃基甲基N-杂环。化合物6d，8b和12a对MTB H37Rv菌株表现出优异的活性（MIC：0.031–0.062μg/ mL），与INH和IIIM-MCD-211大致相当。此外，利用比较分子场分析（CoMFA）和比较分子相似性指数分析（CoMSIA）技术对上述化学系列进行了三维定量构效关系（3D-QSAR）研究。已开发的CoMFA和CoMSIA模型显示出较高的外部可预测性（r ² _pred分别为0.954和0.935）和良好的统计稳健性。更重要的是，如预期的那样，发现基于两种模型的新设计的化合物16a和16b（MIC：<0.016μg/ mL）比12a和IIIM-MCD-21更具活性。目前正在进行更有效的硝基呋喃基甲基N-杂环化合物作为抗结核病药物的设计和合成。
