Carbocyclic analogues of 2-amino-6-substituted-purine 3'-deoxyribofuranosides were synthesized by beginning with (+/-)-(1 alpha,3 alpha,4 beta)-3-amino-4-hydroxycyclopentanemethanol and 2-amino-4,6-dichloropyrimidine. The route parallels the earlier syntheses of the corresponding ribofuranoside and 2'-deoxyribofuranoside analogues. The 2-amino-6-chloropurine, guanine, and 2,6-diaminopurine derivatives
通过从(+/-)-(1 alpha,3 alpha,4 beta)-3-amino-4-hydroxycyclopentanemethanol和2-amino--开始合成2-氨基-6-取代的嘌呤3'-脱氧核糖呋喃糖苷的碳环类似物4,6-二氯嘧啶。该路线平行于相应的呋喃呋喃糖苷和2'-脱氧核糖呋喃糖苷类似物的早期合成。制备了2-氨基-6-氯嘌呤,鸟嘌呤和2,6-二氨基嘌呤衍生物以及类似的8-氮杂嘌呤。3'-脱氧鸟苷的类似物(3'-CDG)在体外对诱导胸苷激酶的1型单纯疱疹病毒(HSV-1)菌株具有活性,对诱导2型HSV的胸苷激酶诱导的菌株具有适度活性。3'-CDG对缺乏胸苷激酶诱导能力的HSV-1菌株无效,而2-氨基-6-氯嘌呤3'-脱氧核糖呋喃糖苷的碳环类似物对该菌株具有活性。2,6-二氨基嘌呤3'-脱氧核糖呋喃糖苷的碳环类似物在体外对流感病毒显示适度的活性。
