Discovery of 2′-α-C-Methyl-2′-β-C-fluorouridine Phosphoramidate Prodrugs as Inhibitors of Hepatitis C Virus
摘要:
2'-alpha-C-Methyl-2'-beta-C-fluorouridine and its phosphoramidate prodrugs were synthesized and evaluated for their inhibitory activity against HCV. The structure-activity relationship analysis of the phosphoramidate moiety found that 17m, 17q, and 17r exhibit potent activities against HCV, with EC50 values of 1.82 +/- 0.19, 0.88 +/- 0.12, and 2.24 +/- 0.22 mu M, respectively. The docking study revealed that the recognition of the 2'-beta-F by Arg158, 3'-OH by N291, and the Watson Crick pairing with the template allowed 23 to form the in-line conformation necessary for its incorporation into the viral RNA chain.

HepatitisCvirus (HCV) is a global health problem requiring novel approaches for effective treatment of this disease. The HCV NS5Bpolymerase 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 NS5Bpolymerase 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。
Compounds of Formula I: I and their pharmaceutically acceptable salts are useful for the inhibition of HIV reverse transcriptase. The compounds may also be useful for the prophylaxis or treatment of infection by HIV and in the prophylaxis, delay in the onset or progression, and treatment of AIDS. The compounds and their salts can be employed as ingredients in pharmaceutical compositions, optionally in combination with other antiviral agents, immunomodulators, antibiotics or vaccines.
