Chronic hepatitis C (CHC) is a major liver disease caused by the hepatitis C virus. The current standard of care for CHC can achieve cure rates above 95%; however, the drugs in current use are administered for a period of 8–16 weeks. A combination of safe and effective drugs with a shorter treatment period is highly desirable. We report synthesis and biological evaluation of a series of 2′,3′- and
慢性丙型肝炎 (CHC) 是由丙型肝炎病毒引起的主要肝脏疾病。目前CHC的护理标准可以达到95%以上的治愈率;然而,目前使用的药物的给药期为 8-16 周。非常需要安全有效的药物与较短治疗期的组合。我们报告了一系列 2',3'- 和 2',4'- 取代的鸟苷核苷酸类似物的合成和生物学评价。它们的三磷酸盐表现出对 HCV NS5B 聚合酶的有效抑制作用,IC 50低至 0.13 μM。在 HCV 复制子测定中,这些类似物的氨基磷酸酯前药表现出优异的活性,EC 50值低至 5 nM。一种铅化合物AL-611 在口服给药后,在体外原代人肝细胞和体内狗肝中显示出高水平的核苷 5'-三磷酸。
