The synthesis of a novel library of purine derivatives bearing various bicyclic and polycylic substituents at the N‐9 position is described. The series includes norbornanes, bicyclo[2.2.2]octanes, and bicyclo[3.2.1]octanes attached at the bridgehead position as well as bicyclo[3.1.1]heptanes, tetrahydro‐1‐naphthalenes, and adamantanes bonded either directly or via a linear chain to the 6‐chloropurine
描述了在 N-9 位置带有各种双环和多环取代基的新型嘌呤衍生物库的合成。该系列包括在桥头位置连接的降冰片烷、双环[2.2.2]辛烷和双环[3.2.1]辛烷以及直接或通过连接的双环[3.1.1]庚烷、四氢-1-萘和金刚烷6-氯嘌呤核碱基的线性链。许多制备的衍生物对肠道病毒具有显着的活性。尽管试图将针对小核糖核酸病毒的活性与其磷脂酰肌醇 4-激酶 KIIIβ 抑制活性相关联,但很明显,这种宿主因子的抑制不能解释观察到的抗病毒效力。
