time-of-addition studies using FTCRI and by the resistance of TCRB-resistant strains of HCMV to four different 3-substituted indole ribonucleosides. The 2'-deoxy analogues of the trichlorinated indole nucleosides also had potent antiviral activity, in contrast to decreased activity and selectivity observed for 2'-deoxy TCRB compared to TCRB. In addition, 3-acetyl-2,5,6-trichloro-1-(2-deoxy-beta-d-ribofuranosyl)indole
已合成了一系列氯化吲哚核苷,并测试了其对人巨细胞病毒(HCMV)和1型单纯疱疹病毒(HSV-1)的活性以及细胞毒性。报道的3-甲酰基-2,5,6-三氯-1-(β-D-呋喃呋喃糖基)吲哚(FTCRI)和3-氰基-2,5,6-三氯的2'-和5'-脱氧衍生物通过对适当的3-未取代的糖修饰的核苷类似物进行修饰或通过将3-取代的杂环与受保护的α-氯糖进行糖基化来合成-1-(β-D-呋喃呋喃糖基)吲哚(CTCRI)。修饰的部分原因是与相应的一系列氯化苯并咪唑核糖核苷的结构相似,以及2,5,6-三氯-1-(β-D-呋喃呋喃糖基)苯并咪唑(TCRB)的5'-脱氧类似物非常重要对HCMV有效。5' FTCRI和CTCRI的-脱氧类似物的活性几乎与FTCRI和CTCRI一样,这表明氯化苯并咪唑核苷和氯化吲哚核苷的作用方式相似。使用FTCRI的加法时间研究以及HCMV的TCRB抗性菌株对四种不同的3个取代的吲哚
