A series of phosphate esters of 9-[(1,3-dihydroxy-2-propoxy)methyl]guanine (DHPG, 1) were synthesized and evaluated for antiherpes virus activity. The cyclic phosphate esters were made by a new, efficient method utilizing stannic chloride as a solubilizing agent. Monophosphate 2 and bisphosphate 4 showed comparable activity to DHPG and probably acted as prodrugs of DHPG. On the other hand, the cyclic
合成了一系列9-[((1,3-二羟基-2-丙氧基)甲基]鸟嘌呤的磷酸酯(DHPG,1),并评估了抗疱疹病毒的活性。环状磷酸酯是通过使用氯化锡作为增溶剂的一种有效的新方法制备的。单磷酸酯2和双磷酸酯4具有与DHPG相当的活性,可能充当DHPG的前药。另一方面,DHPG 3的环状磷酸酯被细胞吸收并绕过病毒指定的胸苷激酶。结果,3对缺乏病毒特异性胸苷激酶的DHPG抗性HSV突变体具有活性,对未感染细胞的毒性比DHPG高。在测试的衍生物中毒性最低的膦酸酯5对HSV的活性很小,但在体外对人巨细胞病毒却显示出实质性的活性。
