针对抗结核药物新靶酶——腺苷酰化酶家族的泛酸合成酶, 以生物电子等排原理, 模拟泛酸合成酶催化的中间体, 用氟取代中间体糖环上2'位羟基, 合理设计了目标化合物5'-O-{[(R)-2-羟基-3,3-二甲基丁酰基]磺酰胺基}-2'-去氧-2'-氟腺苷(1). 以D-叔亮氨酸和阿糖腺苷为原料, 通过9步反应合成得到目标产物. 其结构经1H NMR, 13C NMR 和HRMS表征确认.

关键词: 氟代腺苷衍生物, 泛酸合成酶, 抗结核, 全合成

Pantothenate synthetase (PS), a member of adenosine acylation enzyme family, was the new target of anti-tuberculosis drug development. Employing bioisostere principle, 5'-O-{[(R)-2-hydroxy-3,3-dimethylbutanoyl]sulfamoyl}-2'-deoxy-2'-fluoroadenosine (1), a mimic of the PS catalyzed reaction intermediate, was rational designed by substituting the 2'-hydroxyl group of intermediate sugar ring with fluorine. This compound was synthesized using D-tertiary leucine and vidarabine as the starting materials by 9 steps of reaction, and its structure was fully characterized by 1H NMR, 13C NMR and HR-MS techniques.

Key words: fluorinated adenosine derivative, pantothenate synthetase, anti-tuberculosis, total synthesis
