Three types of sugar modified pyrimido[4,5-b]indole nucleosides (2′-deoxy-2′-fluororibo-, 2′-deoxy-2′-fluoroarabino- and arabinonucleosides) were synthesized by glycosylation of 4,6-dichloropyrimido[4,5-b]indole followed by modification of sugar moiety and introduction of substituents into position 4 by cross-coupling reactions or nucleophilic substitutions. Some 2′-fluororibo- and 2′-fluoroarabinonucleosides
通过4,6-二氯嘧啶基的糖基化反应,合成了三种类型的糖修饰的嘧啶并[4,5- b ]吲哚核苷(2'-脱氧-2'-氟核糖-,2'-脱氧-2'-氟阿拉伯糖核苷和阿拉伯糖核苷)。 [4,5- b ]吲哚,其后修饰糖部分,并通过交叉偶联反应或亲核取代将取代基引入位置4。一些2'-氟核糖核苷和2'-氟阿拉伯糖核苷显示出有趣的抗HCV活性(IC 50 = 1.6–20μM),后一种化合物也具有一些抗登革热活性(IC 50 = 10.8–40μM)。
