Several "sugar" modified acyclic nucleoside analogues related to 9-[(1,3-dihydroxy-2-propoxy)methyl]guanine (DHPG, 2) were synthesized and evaluated for antiviral activity. The preparation generally involved the condensation of the acetoxymethyl ether of alcohols 6c-g and 10-12a with diacetylguanine to give adducts 7c-g and 14-16, which were then deprotected to afford analogues 9c-g and 17-19. Alternatively
合成了几种与9-[(1,3-二羟基-2-丙氧基)甲基]鸟嘌呤(DHPG,2)有关的“糖”修饰的无环核苷类似物,并评估了其抗病毒活性。制备通常涉及将醇6c-g和10-12a的乙酰氧基甲基醚与二乙酰鸟嘌呤缩合,得到加合物7c-g和14-16,然后将其脱保护得到类似物9c-g和17-19。或者,将醇12a和13a通过它们的甲苯磺酸酯12b和13b转化为碘化物,然后与鸟嘌呤的钠盐反应,得到脱保护后的类似物22和23。醛27上的醛醇-Cannizzaro交叉反应容易得到28,其脱保护得到类似物29。针对HSV-1的体外分析表明,所测试的所有化合物的活性均低于DHPG,尽管有几种是病毒胸苷激酶的良好底物。在小鼠脑炎模型中评估了更有前途的无环核苷9c,19和29,并证明在20 mg / kg的剂量下无法有效预防死亡。
