of 1,5-anhydrohexitol nucleosides is described. These nucleoside analogues were obtained by alkylation of the heterocyclic bases with the tosylate 10 or by alkylation of the bases with the alcohol 12 under Mitsunobu conditions. The compounds were evaluated for antiviral and cytostatic activity. Highly selective activity against herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) was noted for 1,5-anhydro-2
描述了1,5-脱水己糖醇核苷的合成。这些核苷类似物是通过在甲苯磺酰脲(Mitsunobu)条件下用甲苯磺酸酯10使杂环碱烷基化或通过用醇12使碱烷基化而获得的。评价化合物的抗病毒和细胞抑制活性。对于1,5-脱水-2,3-二脱氧-2-(5-碘尿嘧啶-1-基)-D注意到对1型单纯疱疹病毒(HSV-1)和2型单纯疱疹病毒(HSV-2)具有高度选择性。 -阿拉伯糖基己糖醇4b的浓度为0.07微克/毫升。此活性必须取决于病毒编码的胸苷激酶(TK)的特定磷酸化作用,因为化合物4b对HSV-1的TK缺陷型突变体无活性。相应的胞嘧啶4c和鸟嘌呤4e类似物对HSV-1,HSV-2和其他疱疹病毒(例如巨细胞病毒,水痘-带状疱疹病毒)浓度远低于细胞毒性阈值(分别为2和20微克/ mL)。在这些浓度下,化合物4c和4e还被证明对人类T细胞(即MT-4,CEM,MOLT-4)的生长具有抑制作用。
