A series of novel 2′-deoxy-2′-α-fluoro-2′-β-C-methyl 3′,5′-cyclic phosphate nucleotide prodrug analogs were synthesized and evaluated for their in vitro anti-HCV activity and safety. These prodrugs demonstrated a 10–100-fold greater potency than the parent nucleoside in a cell-based replicon assay due to higher cellular triphosphate levels. Our structure–activity relationship (SAR) studies provided
合成了一系列新型 2'-deoxy-2'-α-fluoro-2'-β- C-甲基 3',5'-环状磷酸核苷酸前药类似物,并对其体外抗 HCV 活性和安全性进行了评估。由于更高的细胞三磷酸盐水平,这些前药在基于细胞的复制子测定中显示出比母体核苷高 10-100 倍的效力。我们的构效关系 (SAR) 研究提供了在大鼠口服给药时在大鼠肝脏中产生高水平活性三磷酸盐的化合物。这些研究最终导致了临床开发候选者24a (PSI-352938) 的选择。
