evaluation of new furan derivatives targeting Mycobacterium tuberculosis salicylate synthase (MbtI). A receptor-based virtual screening procedure was applied to screen the Enamine database, identifying two compounds, I and III, endowed with a good enzyme inhibitory activity. Considering the most active compound I as starting point for the development of novel MbtI inhibitors, we obtained new derivatives
我们报告针对结核分枝杆菌水杨酸合酶(MbtI)的新呋喃衍生物的虚拟筛选,合成和生物学评估。应用基于受体的虚拟筛选程序筛选Enamine数据库,鉴定出具有良好酶抑制活性的两种化合物I和III。考虑到最具活性的化合物I作为开发新型MbtI抑制剂的起点,我们获得了基于呋喃支架的新衍生物。在此类SAR中,化合物1a成为迄今为止报道的最有效的MbtI抑制剂(K i = 5.3μM )。此外,化合物1a表现出有希望的抗 分枝杆菌活性(MIC 99 = 156μM),这可能与分枝杆菌素的生物合成抑制有关。
