Hepatitis C virus (HCV) is a global health problem requiring novel approaches for effective treatment of this disease. The HCV NS5B polymerase has been demonstrated to be a viable target for the development of HCV therapies. β-d-2′-Deoxy-2′-α-fluoro-2′-β-C-methyl nucleosides are selective inhibitors of the HCV NS5B polymerase and have demonstrated potent activity in the clinic. Phosphoramidate prodrugs
丙型肝炎病毒 (HCV) 是一个全球性的健康问题,需要新的方法来有效治疗这种疾病。HCV NS5B 聚合酶已被证明是开发 HCV 疗法的可行靶标。β- d -2'-Deoxy-2'-α-fluoro-2'-β- C-甲基核苷是 HCV NS5B 聚合酶的选择性抑制剂,并已在临床上显示出有效的活性。制备了 β- d -2'-deoxy-2'-α-fluoro-2'-β- C-甲基尿苷核苷的 5'-磷酸衍生物的氨基磷酸酯前药,并在 HCV 亚基因组复制子测定中显示出显着的效力(< 1 μM)并产生高水平的三磷酸盐6当体内给药时,在原代肝细胞和大鼠、狗和猴子的肝脏中。使非对映体混合物14的单一非对映体51结晶,确定X射线结构,将氨基磷酸酯立体化学建立为S p ,从而首次将氨基磷酸酯前药的立体化学与生物活性相关联。51(PSI-7977)被选为临床开发候选者。
