identify a potent and selective nucleoside inhibitor of dengue virus RNA-dependent RNA polymerase, a series of 2'- and/or 4'-ribose sugar modified uridine nucleoside phosphoramidate prodrugs and their corresponding triphosphates were synthesized and evaluated. Replacement of 2'-OH with 2'-F led to be a poor substrate for both dengue virus and human mitochondrial RNA polymerases. Instead of 2'-fluorination
为了鉴定登革热病毒依赖RNA的RNA聚合酶的有效和选择性核苷抑制剂,合成并评估了一系列2'-和/或4'-核糖修饰的尿苷核苷氨基磷酸酯前药及其相应的三磷酸酯。用2'-F替代2'-OH导致登革热病毒和人类线粒体RNA聚合酶的底物均较差。代替2'氟化,发现在核糖4'位置引入氟并不会影响线粒体RNA聚合酶的吸收,从而抑制了登革病毒聚合酶的抑制。2'-C-乙炔基-4'
