report herein the design and synthesis of “novel imidazo [1,2-a]pyridine-3-carboxamides (IPAs)” bearing a variety of different linkers, based on the structure of IMB-1402 discovered in our lab. Results reveal that 2,6-dimethyl-N-[2-(phenylamino)ethyl] IPAs with an electron-donating group on the benzene ring as a potent scaffold. Compounds 26g and 26h have considerable activity (MIC: 0.041–2.64 μM) against
我们在此报告基于我们实验室中发现的IMB-1402的结构和合成的“新型咪唑并[1,2- a ]吡啶-3-甲酰胺(IPA)”的设计和合成。结果表明,在苯环上具有给电子基团的2,6-二甲基-N- [2-(苯基氨基)乙基] IPAs作为有效的支架。化合物26g和26h对药物敏感/耐药的MTB菌株具有相当大的活性(MIC:0.041–2.64μM),并且它们对MTB H37Rv的安全性指标可接受,SI值分别为4395和1405。此外,N- [2-(哌嗪-1-基)乙基]部分也被鉴定为潜在的替代接头(化合物31),为进一步的SAR研究开辟了新的方向。
