series of novel substituted isatin ribonucleosides 3b-3f were synthesized in good yields by a TMSOTf catalysed coupling reaction between the silylated nitrogenated base (1b-1f) and 1-O-acetyl-2,3,5-tri-O-benzoyl-beta-D-ribofuranose (2). Isatin nucleoside 3a previously reported was also prepared using this method giving high yield. From the compounds tested, ribonucleoside 3f proved to be the most active
通过TMSOTf催化的甲硅烷基化的氮化碱(1b-1f)与1-O-乙酰基-2,3,5-三-O-苯甲酰基-之间的偶联反应以高收率合成了一系列新型取代的靛红核糖核苷3b-3f β-D-呋喃核糖(2)。还使用该方法制备了先前报道的伊斯丁核苷3a,具有高收率。从被测化合物中,核糖核苷3f被证明是对HSV-1感染细胞的抗病毒活性最活跃的化合物,可抑制66%的病毒产量。测试的所有伊斯兰衍生物均未抑制HIV-1逆转录酶(RT)活性。
