    Journal: J Med Chem; 1987 Jun; 30(6):1090-4. PubMed ID: 3035178.
    Abstract:
    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 and the analogous 8-azapurines were prepared. The analogue (3'-CDG) of 3'-deoxyguanosine is active in vitro against a strain of type 1 herpes simplex virus (HSV-1) that induces thymidine kinase and is modestly active against a thymidine kinase inducing strain of type 2 HSV. 3'-CDG is not active against a strain of HSV-1 that lacks the thymidine kinase inducing capacity, whereas the carbocyclic analogue of 2-amino-6-chloropurine 3'-deoxyribofuranoside is active against that strain. The carbocyclic analogue of 2,6-diaminopurine 3'-deoxyribofuranoside displayed modest activity in vitro against influenza virus.
