The synthesis, biochemical, and biological evaluation of a systematic series of 2-triazole derivatives of 5'-O-[N-(salicyl)sulfamoyl]adenosine (Sal-AMS) are described as inhibitors of aryl acid adenylating enzymes (AAAE) involved in siderophore biosynthesis by Mycobacterium tuberculosis. Structure-activity relationships revealed a remarkable ability to tolerate a wide range of substituents at the 4-position
5'-O-[N-(水杨基)氨磺酰基]腺苷 (Sal-AMS) 的系统系列 2-三唑衍生物的合成、生化和生物学评价被描述为参与的芳酸腺苷酸化酶 (AAAE) 的抑制剂在结核分枝杆菌的铁载体生物合成中。构效关系揭示了在三唑部分的 4 位具有显着的耐受各种取代基的能力,并且大多数化合物具有亚纳摩尔的表观抑制常数。然而,体外效力并不总是转化为抗结核分枝杆菌的全细胞生物活性,这表明内在抗性在观察到的活性中起重要作用。此外,
