A series of tritylated and dimethoxytritylated analogues of selected pyrimidine and purine nucleosides were synthesized and evaluated for their in vitro inhibitory activity against two important members of the genus Flavivirus in the Flaviviridae family, the yellow fever (YFV) and dengue viruses (DENV). Among all compounds tested, the 5′‐O‐tritylated and the 5′‐O‐dimethoxytritylated 5‐fluorouridine
合成了一系列选定的嘧啶和嘌呤核苷的三苯甲基化和二甲氧基三苯甲基化的类似物,并评估了它们对黄病毒科中黄病毒属的两个重要成员黄热病和登革热病毒的体外抑制活性。在所有测试的化合物中,5'-O-三苯甲基化和5'-O-二甲氧基三苯甲基化的5-氟尿苷衍生物均具有抗YFV的能力。有趣的是,在嘌呤类似物系列中,5'O,N-双三苯甲基化的氟达拉滨衍生物在μm浓度下表现出对DENV的强抑制活性,但对YFV的效力却明显减弱。
