We report the synthesis and biological evaluation of a series of 4'-fluoro-2'- C-substituted uridines. Triphosphates of the uridine analogues exhibited a potent inhibition of hepatitis C virus (HCV) NS5B polymerase with IC50 values as low as 27 nM. In an HCV subgenomic replicon assay, the phosphoramidate prodrugs of these uridine analogues demonstrated a very potent activity with EC50 values as low
我们报告了一系列 4'-fluoro-2'- C-取代尿苷的合成和生物学评价。尿苷类似物的三磷酸盐表现出对丙型肝炎病毒 (HCV) NS5B 聚合酶的有效抑制作用,IC50 值低至 27 nM。在 HCV 亚基因组复制子测定中,这些尿苷类似物的氨基磷酸酯前药表现出非常有效的活性,EC50 值低至 20 nM。先导化合物 AL-335 (53) 在体外单次口服剂量后,在人原代肝细胞和 Huh-7 细胞以及狗肝脏中表现出高水平的三磷酸核苷。化合物 53 被选择用于临床开发,在 1 期和 2 期试验中显示出有希望的结果。
