1-O-Acetyl-2,3,5-tri-O-benzyl-4-thio-L-arabinofuranoside (6) was transformed in two steps into the 1-(4-thio-L-arabinofuranosyl)-5-halopyrimidine nucleosides 10, 11 and 12, obtained as anomeric mixtures which were separable in the case of 10 and 11. No in vitro antiviral activity against HIV-1 and HIV-2. TK+ and TK- VZV and CMV has been found for 10, 11 and 12.
将1-O-乙酰基-2,3,5-三-O-苄基-4-硫代-L-阿拉伯呋喃糖苷(6)分两步转化为1-(4-硫代-L-阿拉伯呋喃糖基)-5-卤代嘧啶以异头混合物形式获得的核苷10、11和12,在10和11的情况下是可分离的。没有针对HIV-1和HIV-2的体外抗病毒活性。已发现TK +和TK- VZV和CMV分别为10、11和12。
