Cycloaddition of 7a, b with 6 gave, after separation and deprotection, two regioisomers 10a, b and 11a, b. The deprotected acyclic nucleoside 10a used as the precursor for the preparation of 4-amino (12), 4-methylamino (13), 4-benzylamino (14), 4-methoxy (15) and 4-hydroxy (16) analogues. All acyclic nucleosides were evaluated for their inhibitory effects against HIV-1(IIIB), HIV-2(ROD) in MT-4 cells
在分离和脱保护后,将7a,b与6环加成,得到两个区域异构体10a,b和11a,b。脱保护的无环核苷10a用作制备4-
氨基(12),4-甲基
氨基(13),4-苄基
氨基(14),4-甲氧基(15)和
4-羟基(16)类似物的前体。评价了所有无环核苷对
MT-4细胞中HIV-1(IIIB),HIV-2(ROD)的抑制作用,抗肿瘤活性以及对结核分枝杆菌的抑制作用。找不到明显的活动。
