MbtA催化分枝杆菌素的第一个重要的生物合成步骤,这是与结核分枝杆菌中铁摄入有关的重要毒力因子。MbtA是抗结核药物开发的经过验证的治疗靶标。5'- O- [ N-(水杨基)氨磺酰基]腺苷(1)是MbtA的双底物抑制剂,具有极强的生化和抗结核活性。然而,1的药物处置特性欠佳,导致半衰期短(t 1/2),低暴露(AUC)和低生物利用度(F)。采取了四种策略来解决这些问题,包括前药的合成,增加酰基磺酰基部分的p K a,调节亲脂性以及将氟引入1的策略。对所有化合物进行了完整的药代动力学(PK)分析。最成功的修饰涉及核苷的氟化,这可显着改善t 1/2和AUC。增加酰基-磺酰基接头的p K a会产生增量的增强,而亲脂性和前药方法的调节则导致PK参数大大降低。
