Optically pure acyclic nucleoside analogues with a 3(S),5-dihydroxypentyl or 4(R)-methoxy-3(S),5-dihydroxypentyl side chain were synthesized starting from 2-deoxy-D-ribose. The acyclic nucleosides were obtained by alkylation of the bases with the mesylates 16 and 17. Of these series of novel nucleoside analogues only 9-[3(S),5-dihydroxypent-1-yl]guanine (6d) showed marked antiviral activity. It inhibited the
从2-脱氧-D-核糖开始合成具有3(S),5-二羟基戊基或4(R)-甲氧基-3(S),5-二羟基戊基侧链的光学纯的无环核苷类似物。通过用甲磺酸酯16和17使碱基烷基化获得无环核苷。在这一系列新型核苷类似物中,只有9- [3(S),5-二羟基戊-1-基]鸟嘌呤(6d)显示出显着的抗病毒活性。它以0.4-0.6微克/毫升的浓度抑制1型单纯疱疹病毒(HSV-1)的细胞致病性,因此表明其抗病毒活性比最近报道的R和S对映异构体混合物(12.5微克/毫升)高。毫升)。与6d相反,其4(R)-甲氧基衍生物7d没有显示抗病毒活性,这意味着4'-甲氧基不能模仿正常呋喃糖环的1',4'-氧桥。
