5'-O-[N-(salicyl)sulfamoyl]adenosine (Sal-AMS) is a prototype for a new class of antitubercular agents that inhibit the aryl acid adenylating enzyme (AAAE) known as MbtA involved in biosynthesis of the mycobactins. Herein, we report the structure-based design, synthesis, biochemical, and biological evaluation of a comprehensive and systematic series of analogues, exploring the structure-activity relationship
5'-O-[N-(水杨基)氨磺酰基]腺苷 (Sal-AMS) 是一类新型抗结核药物的原型,可抑制参与分枝杆菌素生物合成的称为 MbtA 的芳酸腺苷酸化酶 (AAAE)。在此,我们报告了一系列全面系统的类似物的基于结构的设计、合成、生化和生物学评估,探索了 Sal-AMS 嘌呤核碱基结构域的构效关系。值得注意的是,2-苯基-Sal-AMS 衍生物 26 表现出异常有效的抗结核活性,在 0.049 microM 的缺铁条件下具有 MIC99,而 N-6-环丙基-Sal-AMS 16 导致提高的效力和 64-增强铁缺乏条件下相对于铁充足条件下的活性,与设计的作用机制一致的表型。
